Dreams and Dreamings Completed by 4B class student Maria Naydenova
The purpose of the research work: to find out the meaning of sleep and dreams for humans.
My Tasks 1. study information on this topic using popular scientific literature and Internet resources. 2. Systematize the acquired knowledge. 3. Present your findings in a presentation.
Hypotheses A person sees in a dream what he thinks about. A person sees dreams that then come true. Sleep and dreams are vital for humans.
History of the study of sleep Empedocles Hippocrates Aristotle “Sleep occurs as a result of a slight decrease in the heat contained in the blood.” “The cooling of the members of the sleeper is caused by the outflow of blood and heat into the internal regions of the body.” “The immediate cause of sleep is contained in the food we eat, which releases Spirits. Body heat directs these perfumes to the head, where they accumulate and cause drowsiness.
What is sleep? Sleep is natural physiological process being in a state with a minimum level brain activity and decreased response to the world.
Dream Structure healthy person sleep begins with the first stage of slow-wave sleep, which lasts 5-10 minutes. Then comes the 2nd stage, which lasts about 20 minutes. Another 30-45 minutes occur during stages 3-4. This entire sequence is called a cycle. The first cycle lasts 90-100 minutes. Then the cycles are repeated, with the proportion of slow-wave sleep decreasing, and the proportion of slow-wave sleep gradually increasing. REM sleep.
Functions of Sleep Sleep provides rest for the body. Sleep promotes the processing and storage of information. Sleep (especially slow sleep) facilitates consolidation of the studied material, while REM sleep implements subconscious models of expected events. Sleep is the body's adaptation to changes in illumination. Sleep restores the immune system by activating it to fight colds and viral diseases.
Why and when you don't dream When people sleep, they always dream, even if it seems like they're not. It's just that people often don't remember their dreams. There could be many reasons for this, starting with bad conditions for sleep and ending with insufficient duration.
There are many theories related to the question “Why do we dream?”, some are physiological, others are psychological, and some are a combination of different ideas. The relationship between sleep and daytime activities and emotions. Most research confirms that the daily activities that happen to us in waking state, has some influence on dreams, according to at least, part of the sleep time. In many cases, people can see connections between their dreams and the hopes, fears, worries, and experiences that occur in daily life. Our dreams may be one of the mechanisms our brain uses to find agreement between emotionally charged or traumatic events that happen to us while we are awake.
Activation Theory When considering the question “Why do we dream?”, activation theory suggests that dreams are the result of the brain trying to organize random signals, messages, memories and everyday activities into something recognizable. This theory believes that there is no real logic or reason why our dreams develop. Freudian Explanation Theoretically, the answer to the question “Why do we dream?”, which was popular in its day but has now received less attention, was put forward by Sigmund Freud. In his own words, S. Freud believed that sleep could be “the hidden fulfillment of repressed desires.” In other words, he believed that we hold back certain emotions and actions in our conscious world because they may be socially unacceptable. However, during sleep, the brain feels free to explore these activities. However, not a single study has proven Freud's hypothesis.
Justification Everyday life This is a more recent theory about why we dream, which puts elements of different theories together to create a new one. During sleep, the brain takes in the thoughts, ideas and emotions that a person experiences while awake and mixes information together in an attempt to interpret and organize it in a way that is consistent with each person's beliefs.
When we go to bed, what do we usually think about? About the time we lived, in this or that period, about how we behaved in this or that situation, about how we should have behaved and what happened then. We also dream about the future, imagining its various variations. In this regard, dreams are divided into three types: Everyday ones, where a person participates in resolving various life situations, or experiences some sad events; Significant, where some actions are performed that are not typical for real life the dreamer, and where some symbols are observed in the form of numbers, memorable objects or words spoken by another character; Prophetic things that can show a person what can happen or happen in a given situation, and give a hint to avoid unwanted events. People seeing prophetic dreams are quite rare and can be called gifted to some extent, since their brains are much more capable of receiving information from invisible sources than others. Over hundreds of thousands of years, people have created various dream books, based on observations and generalized into the basic meanings of objects and situations. But, as a rule, it is difficult to judge an upcoming event from one object taken from the context of a dream. Often we dream of such nonsense that it is not only impossible to define its meaning, it is impossible to wrap it in a plot.
It has also been noticed that the most vivid and colorful dreams with a full range of sensations are dreamed by creative people, with developed imagination, as well as for children. Maybe that's why they are remembered better. The essence of the question is also how to treat dreams as a fact, because people with a technical background, skeptics, whose thinking is built on “mathematics”, treat dreams insofar as they are. That is, without interest and they are not at all concerned about what they see or do not see, they have other concerns. As a result, their dreams can be dull, black and white, and easily forgotten. There is also a belief among dreamers that if you immediately look out the window after waking up, the dream will be forgotten.
How much sleep do you need? “Five hours of sleep for the young and the old, six for the merchant, seven for the aristocrats, and eight hours for the lazy and complete slackers.” Lausius (ancient poet) There is no single necessary sleep time for all people. The duration and depth of sleep depend on the person’s character, age, work, habits, and degree of fatigue. There are "larks", "owls", "pigeons".
Napoleon went to bed at 22-24 am and slept until 2 am Then he got up, worked until 5 am, then fell asleep until 7 am Churchill worked until 3-4 am, and at 8 am he was on his feet again Albert Einstein spent every night in bed 10 -12 hours Short sleepers Long sleepers
Time needed for sleep Newborns (0-2 months) 12-18 hours Infants (3-11 months) 14-15 hours Toddlers (1-3 years) 12-14 hours Preschoolers (3-6 years) 11-13 hours Children school age(6-10 years old) 10-11 hours Teenagers (11-17 years old) 8-9 hours Adults 7-9 hours
factors that can lead to sleep disturbances To get a good night's sleep, you need to sleep for about seven to nine hours and eliminate: caffeinated drinks; alcohol; smoking; too hot or too cold room temperature; antidepressants.
“Prophetic dreams” “A dream is an unprecedented combination of past impressions” Ivan Sechenov. What did anyone dream about: Albert the Great - Plan of the Cologne Cathedral Giuseppe Tartini - Dante’s famous “Sonata of the Devil” - “ The Divine Comedy» Goethe - The second part of “Faust” Griboyedov - “Woe from Wit” D.I. Mendeleev - periodic table chemical elements To the chemist August Kekule - the formula of benzene that he worked on for a long time. To A.S. Pushkin - two lines from the poem “Licinius” by Voltaire - a whole poem, this was the first version of the “Henriad”. La Fontaine composed the fable “Two Doves” in a dream; Beethoven composed a play in a dream. Derzhavin composed the last stanza of the ode “God” in a dream.
Interesting facts about sleep and dreaming The drowsiness stage appears in children aged 8-9 years. Predators dream more than their prey. We dream only what we saw. Our dreams last from 5 to 30 minutes. We see at least 5 dreams per night. We forget 90% of dreams. Blind people dream. People who are blind from birth do not see pictures, but their dreams are filled with sounds, smells and tactile sensations. About 12% of sighted people only see black and white dreams. Others dream in color. All people experience twitching and sudden muscle contractions in their sleep. A person does not dream at the moment when he snores. Even in the womb, the baby dreams. The dreaming phase (REM sleep) helps the development of the brain, so up to 2 years of age, dreams predominate in a child. Young children do not dream about themselves until they are 3 years old. From 3 to 8 years old, children have more nightmares than adults do in their entire lives. If you are awakened during REM sleep, you will remember your dream down to the smallest detail. During sleep, we stop breathing for about 10 seconds on average 5 times a night. With age, the number of such respiratory arrests increases.
Sleep hygiene Regular evening walks before bed are necessary; It is necessary to ventilate the room before going to bed; Go to bed at the same time every night; Along with your clothes, you need to throw off all the worries of the day; You can’t have a heavy dinner before going to bed or drink strong tea or coffee; And remember too long sleep also harmful to a healthy body!
Conclusions: Research has helped reveal that absolutely everyone dreams. If you wake a person during REM sleep, he will be able to describe in detail what he dreamed. At the same time, it is almost impossible to remember a dream interrupted at the stage of slow-wave sleep. For this reason, many people believe that they never dream. In fact, they visit everyone, it’s just that many do not remember them. Over time, chronic sleep deprivation can lead to a host of serious health conditions, including obesity, diabetes, heart disease, and even early death. Learn to wake up correctly. Change your wake-up time so that after your alarm goes off, you still have 10-15 minutes to lie quietly in bed. Change the alarm melody so that it doesn't tear you out of sleep, but helps you wake up slowly. As soon as you wake up, block out all thoughts about the day ahead and what you need to do right now. Try to remember your dream. If you don't succeed the first time, don't be discouraged. Over time, such training will bear fruit, and you will remember your dreams more easily.
Dreams provide access to areas of the unconscious that are inaccessible in the waking state. Without being an expert, you can notice that dreams quite often reflect our expectations related to the future. Thus, the fear of failing an exam causes a school graduate to have a dream of corresponding content. However, dream language is rarely so clear. For example, an exam situation may be dreamed of by people who have completed their studies a long time ago and are not taking any exams. In addition, dreams are rich in strange, unusual “scenery,” so that an event perceived in a dream as an “exam” may most closely resemble, from the point of view of everyday perception, a scene from a “play of the absurd.” The category of time in a dream is much more relative than in the waking state. For example, the dreamer knows exactly “what will happen next” (i.e. has clear information about the “future”), but, at the same time, cannot determine “how it all started” and “how he ended up here” (i.e. .e. does not focus on the “past”). Freud notes that, as a rule, in dreams “thoughts expressing wishes for the future are replaced by a picture taking place in the present.”
In a dream, such a characteristic of time as unidirectionality (from the past to the future) is not observed. Therefore, in dreams we often encounter temporal anomalies: we simultaneously participate in mutually exclusive or spatially separated actions or experience the situation “and then it all started all over again.” Perhaps the fabric of a dream, rich in symbols and complex interweaving of events, has more analogies with the concept of “image of the future” than our more rational and systematized “daytime” ideas. After all, on the one hand, our future is constructed on the basis of past experience, and we see the present through the prism of the future (interflow, not a clear separation). On the other hand, images of the future, like images of dreams, are something that objectively does not exist. And modeling the image of the future is possible only with the help of the language of symbols - that is, the same language with which dreams speak to us.
However, not all dreams are symbolic in nature and need to be “deciphered.” The founder of the psychoanalytic approach to dream interpretation, Sigmund Freud, conditionally divided dreams into three groups. The first group included dreams that had a clear meaning and reflected everyday, real reality. The second group consisted of dreams that took place in realistic conditions, but contained strange, unusual events. And, finally, the third group of dreams was characterized by vagueness and absurdity from the point of view of waking consciousness, i.e. these were dreams that carried symbolic rather than explicit meaning. As an example of dreams of the first category, Freud considered the dreams of children. In these dreams, according to Freud, desires that may be satisfied (or not satisfied) in the near future of the child are reflected in an unchanged form.
However, it would be a mistake to think that absolutely all children's dreams are literal and do not carry any symbolic meaning. Younger schoolchildren already quite often see dreams that can be attributed to both the second and third groups. Especially often threatening images acquire a symbolic nature in children's dreams.
The data from a study of children's dreams are interesting. So, nine-year-old Tim K. dreams of a recurring “ horrible dream" - he flies over an erupting volcano. The events of the dream cannot be called everyday, however, symbolically they reflect what is relevant for the boy. life situation. Without going into psychoanalytic details, we note that Tima associates “volcano” with “danger” and causes fear. The only way out It seems to him to rise as high as possible in order to be out of reach of the “volcano”. The dream drawing he made includes only a volcano and a small figure of the dreamer flying over it. There is no ground or any perspective in the drawing. IN in this case, flight probably symbolizes moving away from a real source of danger into a fantasy world, which is confirmed by data from other studies.
The function of a dream according to S. Freud is an attempt to satisfy a desire. Each desire can have a correspondence with a certain area of the surface of the body (in this case we are talking about the pre-narcissistic split dream body), which is what partial objects represent. In the philosophical and anthropological theory of poststructuralism, the correspondence we expressed between the objects of desire and the body appears in the form of a “body without organs” - a map of the cohesion of partial objects. In their late work “Schizoanalytic cartographies” (“Cartographies schizoanalitiques”, 1989), J. Deleuze and F. Guattari are engaged in constructing such maps for various systems: the unconscious, society, economy.
“I” as the field of dream unfolding is itself on the surface and designates a certain surface. As a “skin” structure, “I” expresses the unity of surface and boundary, since it is formed on the basis of the difference between “mine” and “other”. All this is reflected in the structure of the dream, as the presence of a bodily diagram in the dream tells us. But beyond that, the most fundamental element of this structure is the “screen”.
The concept of a “dream screen” was proposed by psychoanalyst B. Levin and means something onto which a dream picture is projected, while dream space is a mental area in which the dream process is realized as an empirical reality. These are two different, although complementary, mental structures. He interpreted the screen as a symbol of sleep (the desire to sleep) and the merging of the “I” with the chest in a flattened form, to which sleep is unconsciously equated, while the visual images of the dream represent desires that can disrupt the state of sleep. As a result, we can talk about the fundamental interaction of Self and Other in a dream.
In addition to the border and surface, there is another effect that arises along with them - meaning. In relation to the effects of corporeality, meaning appears to be the same element common system, being also an integral part of the dream structure.
Meaning, as an integral part of any boundary, also appears in a dream at the boundary of the interaction of the “I” with the Other, in the space of which this “I” resides in the dream. Moreover, this boundary is a continuation of interaction with the external other. To illustrate what has been said, one can imagine a Möbius strip, in which only by following the surface one can get to its other side: the distinction between the sides of the border, between the dreaming and the dreaming body, is erased. This is the sliding surface of meaning.
R. Barth speaks about signification in the theory of psychoanalysis: “It is known that Freud considered the psyche as a dense network of relationships of significance.” Thus, one of the elements of this relationship represents the explicit meaning (manifester trauminhalt) - the signifier, the other, for example, the substrate of the dream - the hidden (latente traumgedanken), the real - the signified. There is a third element, which, according to the semantic triangle, is the result of the interaction of the first two - the sign (the dream itself).
Let's return to Freud's basic position about dreams as hallucinatory satisfaction of desire. Desire expresses lack. According to Lacan, it has a “contour,” a surface that is formed by the space of the lost object.
A dream is a “metaphor of desire” (R.O. Yakobson). The desire of an object, which does not know satisfaction precisely because of its absence, is a “metonymy of the lack of being” (J. Lacan).
The boundary of a dream is a break in the chain of signifiers, separating the hidden content from the explicit. The mental apparatus produces manifest material from “hidden” material. Such production gives rise to some theorists to consider the mental apparatus as a dream machine. But the dream machine also turns out to be a machine of surfaces. Each element of a dream is a form, a sliding surface of meaning.
According to Jung, dreams play an important additional (or compensatory) role in the psyche Freidger, Freudimer. " General function dreams - to try to restore our psychological balance of producing dream material, which restores in a subtle way the general mental balance.”
Jung approaches dreams as living realities. They must be gained through experience and carefully observed. Otherwise it is impossible to understand them. Paying attention to the form and content of dreams, Jung tried to reveal the meaning of dream symbols and at the same time gradually moved away from the reliance on free associations in the analysis of dreams characteristic of psychoanalysis.
Taylor, postulates basic assumptions regarding dreams:
1. All dreams serve health and wholeness.
2. Dreams do not simply tell the dreamer what he or she already knows.
3. Only the dreamer can say with certainty whether what the dream means can happen.
4. There is no dream with only one meaning.
5. All dreams speak a universal language, the language of metaphor and symbol.
More important than the cognitive understanding of sleep is its understanding as the act of learning from dream material and taking that material seriously.
The lost harmony between consciousness and the unconscious can be restored with the help of dreams. They bring memories, insights, experiences, awaken hidden personality traits and reveal unconscious elements in their relationships.
Thanks to their compensatory behavior, dream analysis opens up new perspectives and ways out of impasses.
In a series of dreams, a phenomenon stands out that is somewhat reminiscent of the process of development within the personality. Individual acts of compensation turn into a semblance of a plan leading to one common goal, like steps along the path of development. Jung called this process of spontaneous self-expression in the symbolism of dream series the process of individuation.
All sleep phenomena can be divided into three categories:
1) The coincidence of the mental state of the observer with what is happening at the moment of this state, an objective, external event that corresponds to the mental state or its contents (for example, a scarab), in which a causal relationship between the mental state and the external event is not traced, and in which, taking into account the mental relativity of time and space, such a connection cannot exist.
2) Coincidence of a mental state with a corresponding (happening more or less at the same time) external event that takes place outside the perception of the observer, that is, at a distance, which can only be verified later (for example, the Stockholm fire).
3) The coincidence of a mental state with a corresponding but not yet existing future event, which is significantly distant in time and the reality of which can also be established only later.
Freud theorized that dreams symbolized a person's unconscious needs and anxieties. He argued that society requires us to suppress many of our desires.
When working with dreams, it is also necessary to take into account Freud's position that the content of dreams comes from real experiences. During sleep, it is only reproduced and remembered, although after waking up a person can deny that this knowledge belongs to his awareness. That is, a person in a dream knows something that he does not remember in the waking state.

Introduction.
This summer a big event happened in our family.My sister Mashenka was born. I noticed that she slept almost all the time. I became interested in how much sleep a child and an adult should sleep.
And also every morning when I wake up, for some reason I always want to sleep. I asked myself the question “Why?” How much sleep should a person actually sleep per day to feel good? Many guys are in a bad mood due to lack of sleep. That's why I decided to do this work.
(Problem )
Every morning when I wake up, for some reason I always want to sleep. I asked myself the question “Why?” How much sleep should a person actually sleep per day to feel good? Many guys are in a bad mood due to lack of sleep.
Therefore, I chose the duration of sleep during the day and week as the object of my research.
(Hypothesis) A junior schoolchild should sleep at least 9 hours a day. Deviation from the norm leads to the development of diseases and affects academic performance.
I set myself the following goals:
1. Find out the opinions of scientific experts on the duration and quality of sleep.
2. Find out why sleep is essential for human health.
3. What determines the quality of sleep?
4. What happens to a person during sleep.
5. Conduct a study in your class to find out how much time students sleep during the week and how this affects their performance.
Main part.
At the first stage of my research work, I turned to scientific sources of psychology and found out:
Dream - a natural physiological process of being in a state with a minimal level of brain activity and a reduced reaction to the outside world, characteristic of mammals, birds, fish and some other animals, including insects.
Sleep is the best remedy restoring wasted energy.We spend a third of our entire lives in it.
The problem of our age is that people do not get enough sleep all the time. Scientists explain that many people are now lacking sleep because they are wasting their sleep time on watching TV shows, surfing the Internet... In addition, scientists found that 37% of the people they surveyed during the research suffer from insomnia, and 24% had other sleep problems.
Not getting enough sleep leads to performance problems immune system, mental fatigue, loss of the ability to adequately perceive reality. Often, “lack of sleep” has devastating consequences for human body can compare with complete absence sleep. It is a common belief that you can train your body to get by with four to five hours of uninterrupted sleep without experiencing any negative consequences.
Most people know that in ancient custom it was necessary to fall asleep at sunset: at sunset it was necessary to go to bed. Now, at this time, “life” is just beginning, especially in cities. Therefore, it is necessary to develop the ability to fall asleep.
However, you should not think that increasing the amount of time allotted to sleep beyond the norm contributes to the restoration and preservation of health. Chronic oversleeping is also harmful for a healthy person. Sleeping longer than nine hours also leads to various dysfunctions of the body: headaches, weight gain. excess weight, back pain, depression, etc. By the way, oversleeping, like lack of sleep, also increases the chances of developing diabetes.
I also had a question: “How long should a child sleep?” - since my little sister sleeps a lot during the first months. Duration baby sleep day and night is a very sore point for many parents with children. How much time a child should sleep affects a large number of factors, for example emotional condition, health status, activity, temperament.
Up to one year, children sleep from 20 to 5 hours during the day, from 8 to 11 hours at night
From 2 to 7 years - from 2 to 1.5 hours, from 11 to 10 hours - at night
From the age of 7, many children have no daytime sleep, and nighttime sleep lasts 9-11 hours. It has been found that lack of sleep can manifest itself bad behavior children.
How many hours a person needs to rest and sleep is a very individual question. In various historical eras, prominent minds of the time asked this question.
Thomas Edison is a world famous American inventor and entrepreneur. Edison received 1093 patents in the USA and about 3 thousand in other countries of the world. He improved the telegraph, telephone, and cinema equipment, developed one of the first commercially successful versions of the incandescent electric lamp, built the first electric locomotives, laid the foundation for electronics, and invented the phonograph. He only needed 4 hours of sleep. Edison believed that sleep was the legacy of the inhabitants of that time, and seriously believed that his invention - the incandescent light bulb, which allows you to turn on the light at any time of the day or night, would put an end to this atavism - sleep - people would sleep much less.
Prime Minister of Great Britain
in 1940-1945
the famous politician Churchill said that those who sleep more than 6 hours a day are inferior people. There were also examples of inveterate sleepers. Einstein usually slept twelve hours a day.
When to go to bed
Better stick a certain regime day, which doesn’t always work out, but it’s worth trying - then health problems associated with sleep disturbances will not visit you.
Our internal biological clock is linked to the length of daylight hours. When the sun goes down and there is less light, the hormone melatonin, a regulator of circadian rhythms, begins to be more actively synthesized in our body.
It “gives a signal” to our organs: it’s time, for example, to reduce the activity of the digestive system and give rest to the heart. In a good way, so as not to go against ours biological clock, you need to sleep at night, not during the day.
People go to bed in different time. Optimally this should be from 10 pm to midnight. Maximum concentration melatonin levels in the blood are observed from 12 am to 4 am. Our dream ends at dawn.
Light blocks the synthesis of melatonin in the body and “wakes” us up. If the body has not had time to recover because someone went to bed late, then there will be little benefit from such sleep.
Some people delay their bedtime in hopes of getting up earlier. They deliberately reduce their sleep duration in hopes of turning from a night owl to a morning person. This should not be done because a person must sleep a certain number of hours a day. Disruption of the biological rhythm can lead to unpredictable consequences. Sleeping less than 5 hours or insomnia can cause many diseases.
What happens in the body when we sleep.
During sleep, many important biochemical processes occur in the body.
1) There is an active synthesis of the energy source for all processes occurring in living systems. Thus, our body stores energy during sleep.
2) Up to 75% of growth hormone is synthesized. Active growth occurs during sleep young body. The same hormone helps burn fat and increases muscle mass.
3) During sleep, testosterone is synthesized, which is responsible for sexual development person. And finally, within 8-9 hours, self-cleaning of the cells and intercellular fluids of the body from metabolic products occurs.
How to sleep properly
Most best pose for sleep experts recognize the position“lying on your back” (Fig. 1.)People sleeping in this position are less likely than others to complain of back pain, neck pain and headaches.From a health point of view, it can lead to snoring, especially if you have problems with the nasopharynx, asthma, or heart problems. From useful features It is worth noting the property of relieving joint pain due to arthritis.
“Kalachik” (Fig. 2)- extremely useful, as it allows you to relieve the spine as much as possible, reduce pressure on the spinal discs, preventing osteochondrosis.
Naturally, a person turns over more than once during the night. But it's best to fall asleep"on the stomach" (Fig. 3). This pose helps straighten the spine. This means general relaxation of the body. This position also allows the kidneys to work as intensively as possible.
“On the side” (Fig. 4) -this position has a therapeutic effect, reducing the severity of heartburn symptoms.
If you have chosen the most convenient and useful posture, but spent no more than five to six hours in it, sleep cannot be considered healthy and restorative.
How long can a person stay awake
Even scientists still cannot answer this question accurately. An interesting experiment was conducted several years ago. Over the course of two weeks, several young people had their sleep gradually reduced from 8 to 4 hours a night. It turned out that by the end of the observations, all of them had sharply increased blood pressure, mental disorders were noted, and there was increased content sugar is the first step to diabetes.
18 days, 21 hours and 40 minutes, this is the amount of time that holds the record for the longest period of no sleep.
Scientists believe that a person can die in 5 days if he is not allowed to sleep. However, reality brings surprises. For example, the American R. Mac Donalds did not sleep for 19 days. His record was recorded in the Guinness Book of Records.
One more example. During the First World War, the Hungarian soldier P. Kern was wounded in frontal lobe brain The doctors cured him, but Paul stopped sleeping. Doctors decided that his days were numbered. However, Kern felt quite well and lived for many years after his injury.
During the era of the ancient Romans, some dreams were even submitted for consideration and interpretation by the Roman Senate. They thought that dreams were messages from the Gods, and during wars and great campaigns, generals had a person with them to interpret their dreams.
American scientists studying dreams have come to a very interesting conclusion. It turns out that dreams are only seen smart people. This conclusion was made as a result of a study of more than two thousand people. Most respondents do not see or do not remember their dreams. Only people who passed a series of intellectual tests with flying colors could say with confidence that they constantly dream. Moreover, the more intellectually developed a person is, the more vivid and colorful his dreams are.
Interesting Facts
It often happens that if a person cannot solve some very important issue for him during the day, then the answer comes in a dream. There are cases in history when such dreams were truly significant.
Mendeleev had a dream in which he saw a table where the chemical elements were arranged in increasing order of their atomic weight.
Chemist August Kekula dreamed of a formula for benzene, which he had been working on for a long time.
The violinist and composer Tartini dreamed of the final movement of the sonata “Devil's Trills”; this sonata is considered one of his best works.
Pushkin dreamed of two lines from the poem “Licinius”
Beethoven composed the play A Midsummer Night's Dream in a dream.
Derzhavin composed the last stanza of the ode “God” in a dream.
What we see in our dreams
People who are blind from birth do not see pictures in their dreams; instead, their dreams contain smells, sounds and sensations.
People forget their dreams very quickly. Literally 5-10 minutes after waking up, we don’t remember even a quarter of what we dreamed at night.
In our dreams we see many people who seem to be strangers to us, but these are not inventions of our subconscious; in fact, we saw these strangers in real life, but we did not remember their faces.
Not all people are able to see vivid dreams saturated with a rich palette of colors.
Approximately 12% of sighted people can only dream in black and white.
The most realistic and intense dreams are seen by people who have given up such a harmful addiction to smoking.
Practical work.
At the next stageIn my work, I conducted research in the classroom in order to find out how much time children spend sleeping and how this affects their performance, as well as the quality of their dreams.
I suggested to the guys:
- Fill out the form.
- Complete the task: on a piece of paper, mark the time allotted for sleep every day for a week.
- Draw pictures about your dreams.
The results of my research.
Due to the fact that the problem of sleep disturbances and lack of sleep is often encountered among students, I decided to research how much time students in my class devote to sleep. Do they observe sleep hygiene, do they dream?
My classmates were given a questionnaire (see Appendix No. 1). During the analysis of the questionnaire, I received the following results.
- By comparing the time they go to bed and how children feel after waking up, I observe a relationship between the quality of sleep and the time the students fall asleep. The later a person falls asleep, the worse he feels, because... he doesn't get enough sleep. 65% of students go to bed late, so 44% do not get enough sleep.
- What time do you go to bed in the evening?
59% at 22.00
35% at 21.00
7% at 20.00
7% at 23.30
How do you feel after sleep?
37% good
15% is normal
44% sleepy
- Comparing the sleep duration of his little sister and
Odnoklassniki, made conclusion :
Sleep duration with age
A person is reduced by almost 2 times.
Having studied how children prepare for sleep and what they most often see in their dreams, I identified a relationship between the quality of sleep (horror dreams - 27%) and bad habits(watching TV and eating before bed) – 30%.
What do you do 30 minutes before bed?
4% nothing
15% read, eat, play
15% watch TV
65% are engaged in hygiene
What do you most often see in your dreams?
7% nothing
11% wildlife
11% family
11% cartoons, funny
11% of acquaintances at the holiday
23% horror
4% site
4% alone on the street
15% racing cars
What kind of dreams do you have?
Colored 88%
Black and white 12%
4. I was also interested in the position in which a person sleeps, and it turned out that most of the children in our class like to sleep on their stomachs and sides. Although sleeping positions have a certain meaning, one should not judge people too quickly. And yet I would like to draw a conclusion from my observations: according to scientists, people who sleep on their stomachs like to command. And indeed, almost half of my classmates are leaders; they love to lead others.
On the back 11%
On the stomach 35%
On the side 50%
- “curl up” 4%
- As a result of research, I found that the majority of my classmates (78%) have a correct idea about the duration of their sleep. I think the other half of the kids will have their misconceptions changed after they get to know my work.
How long do you think a primary school student should sleep at night?
63% 10 hours
7% 11 hours
15% 9 hours
7% 8 hours
4% 5 hours
- Then I gave the guys a task that helped me figure out how much time they spent sleeping during the week.
I compiled a table (Appendix 3) and I was able to calculate the amount of time allocated to sleep by students during the week, and also derived the average amount of time to sleep per day.
Since, according to experts, primary schoolchildren should sleep on average 9 hours, the research shows that
74% of guys sleep the required amount of time or more.
However, it is worth remembering: according to a comprehensive study of the nature of sleep, even one hour of regular sleep deprivation compromises the efficiency of a child's brain functioning, reduces alertness, and also leads to increased fatigue in the early evening.
Here's what happened:
37% of children study with satisfactory grades and sleep on average 8-9 hours a day, and 63% study with good and excellent grades and sleep 9-13 hours a day.
Researchers say lack of sleep reduces children's ability to learn grammar and spelling. native language, and also impairs the understanding of texts. While these abilities are necessary for elementary school students who are just learning to write.
Thus, I observe a direct dependence of students’ academic performance on the duration of their sleep: than smaller child sleeps, the lower his academic performance.
How can I help my classmates improve their performance? I suggested that Irina Anatolyevna conduct Classroom hour on the topic “The Role of Sleep in Human Life,” prepared booklets with recommendations for the children. I think that this will to some extent help the guys reconsider their daily routine and pay attention to proper sleep.
Really junior schoolboy should sleep at least 9 hours a day, or even more. Deviation from the norm leads to the development of diseases and affects academic performance.
Now I understand why my little sister sleeps so much.
Conclusion.
The hypothesis was confirmed. Indeed, a primary school student should sleep at least 9 hours a day. Deviation from the norm leads to the development of diseases, or indicates that not everything is fine in the human body. Lack of sleep negatively impacts student performance.
conclusions
As a result of numerous studies, final conclusions were made:
- Sleep is absolutely essential for human health. For normal functioning, a person needs long and high-quality sleep every day.
- Lack of sleep negatively affects both the physical and mental state of the body.
- The state of a person upon awakening depends on several sleep factors: the duration of sleep and the quality of sleep
- For good health, it is necessary to maintain sleep hygiene.
RESULT: the hypotheses were confirmed.

Introduction
The relevance of addressing this topic is due to the fact that my mother says that I should go to bed on time, get a good night’s sleep and then I will be in a good mood, I will feel cheerful, which means it will be easy for me to study and I will successfully cope with all my tasks. But it turns out that so much time is spent sleeping. During this time I could play on the computer, watch my favorite cartoons, play with friends and much, much more. And you have to go to bed. And every time I’m so reluctant to fall asleep. And in the morning, interestingly, I have difficulty opening my eyes.
I wondered what kind of phenomenon “dream” is? That's the one I chose object your work. How long do I need to sleep? What time should you go to bed? What time do you get up? And when we sleep, we dream. And sometimes they are so interesting and funny. And sometimes scary. And so I decided to conduct my own research to clarify all these questions.
Subject of study -influence of sleep on human health.
Research methods:
Questioning,
Experiment,
Analysis, generalization.
Purpose of the study– study the effect of sleep on human health.
Through research we must confirm hypothesis that good sleep has a positive effect on a person’s health, mood and performance.
Job objectives:
- find out what happens to a person during sleep;
- define best time for sleep and its duration;
- find out how easy it is to fall asleep and wake up.
Main part.
1. Sleep is a gift of nature.
So, sleep. In the electronic encyclopedia, I found the following definition: “sleep is a natural physiological process of being in a state with a minimal level of brain activity and a reduced reaction to the surrounding world, characteristic of mammals, birds, fish and some other animals, including insects.”
Many scientists have studied and continue to study this phenomenon. I found a lot of interesting things about sleep in various sources:
1.1 Types of sleep.
It turns out that each of us has two sleeps: “slow” sleep, lasting 60 minutes, and “fast” sleep (lasting 10 minutes). During the sleep period (6–8 hours) slow sleep It changes quickly several times and it is during this time that a person dreams.
1.2 Significant discoveries.
There are many cases where significant discoveries occurred in a dream. D.I. Mendeleev managed to organize in a dream Periodic table chemical elements,
Mozart heard entire symphonies, Pushkin saw poetry, Beethoven composed a play in a dream.
According to scientists, such insights are possible because dreams create conditions for self-immersion, subconscious processing of information, over which creative person thought intensely while awake.
1.3 Record Randy Gardner.
To some extent, sleep is more important to a person than food. A person can live without food for 2 months, but without sleep - very little. IN ancient China there was an execution: a person was deprived of sleep. And he did not live longer than 10 days.
But the longest period of time without sleep is eighteen days, twenty-one hours and forty minutes. This record was set by seventeen-year-old student Randy Gardner in 1964..
He later spoke about his terrifying mental state. He developed neuroses - feelings of fear, anxiety, tension, various images appeared, vision, memory and logic deteriorated. After the record, Randy slept for fifteen hours. This was enough for him to get some sleep. Since then, the record has not been broken.
2. Research with my friends.
I did my research. My friends Albina and Vadim helped me with this.
2.1 Study No. 1: How much sleep do we need?
There is an opinion that children from 7 to 12 years old should sleep 9-10 hours. We slept for 3 days - 8 hours each, then 3 days - 10 hours each and 3 days - 11 hours each. We rated our well-being on a 10-point scale. And this is what happened:
Well-being assessment | Days |
As you can see, we felt the best from days 4 to 6, that is, it turns out that we really feel bettersleep for 10 hours. 8 hours is not enough for us, and more than 10 hours is also not good for us.
2.2 Study #2: What time should we go to bed?
For 5 days we went to bed at 8 o’clock, then 5 days at 9 and 5 days at 10. Then we noted that at 8 o’clock it was difficult for us to fall asleep, at 9 o’clock Albina and I quickly fell asleep, but Vadik could not sleep. And when we went to bed at 10 o’clock, we felt tired and really wanted to sleep, and Vadim said that for him 10 o’clock is the best time to fall asleep. As it turned out, Albina and I used to go to bed at 9 o’clock, and Vadim at 10. And we concluded that it depends on a person’s habits, but you need to go to bed at the same time, then it will be easier to fall asleep.
3. Fall asleep easily.
I checked them. For 5 days, my friends and I walked before going to bed, took a bath and ventilated the room. After discussing our feelings, we realized that these recommendations really work: we fell asleep faster.
3.2 Advice from doctors.
But how can you easily get up in the morning? Doctors advise:
And what helps me get up quickly is an interesting exercise that I came up with myself and showed to my friends. You need to roll over onto your back, remove the pillow from under your head, lie down straight like a “soldier” and imitate the movements of a caught fish: top part The torso should remain almost motionless, and the legs—more precisely, the feet and shins connected together—should be moved from side to side (while pulling the feet toward you).
My friends and I do this fun exercise every morning, after which we feel invigorated and our mood is lifted.
Conclusion.
After reading the opinions of scientists and conducting my research, I came to the conclusion that sleep is not a time “crossed out” from active life. This is the process during which our body gains strength, preparing us for next day. Good sleep gives us strength, we feel fit, we think clearly. It allows us to concentrate on work throughout the day. The best way to do everything we have planned is to give our body time to rest while sleeping.

Introduction
As evening approaches, everything around calms down, people begin to yawn and go to bed. Why is this happening? Why does a person sleep? Is sleep really necessary?
I noticed that in the mornings I can be cheerful, and sometimes lethargic, even if I am not sick. What does this depend on? Maybe it was the way I slept?
All these questions aroused my interest and determined the topic of my research. The relevance of the topic is the need to preserve the greatest asset of every person - his health. I decided to figure out what sleep is and how it affects my well-being and health in general. Is it possible to find some conditions in order to be cheerful and able to work? As we began working on these issues, we determined:
Object of study:
A man's dream.
Subject of study:
Conditions for adequate sleep for a primary school student.
Target:
Study the role of sleep in maintaining human health.
Tasks:
Explore sleep as a process;
Identify the connection between sleep and health;
To study the features of sleep organization for 3rd grade students at school No. 5;
Research methods:
Collection and analysis of information from various sources;
Conversation;
Questionnaire;
Experiments.
Research hypothesis: Sleep is not a waste of time, but a very important part of our life, which affects our health and ability to work.
In order to prove our hypothesis, we studied theoretical material. Looking for information in books, encyclopedias and the Internet, I learned a lot of new and interesting things. It turns out that this question occupied many scientists, including the world famous - Ivan Pavlov, Sigmund Freud.
Main part
Why are we sleeping?
Sleep is a natural physiological process of being in a state with a minimal level of brain activity and a reduced reaction to the outside world, inherent in birds, fish and some other animals.
Physiologically, ordinary sleep differs from other states similar to it -(“hibernation” in animals),, , , .
Neither man nor animal can always remain awake. It turns out that when tired the body requires rest. Sleep is rest, a protective reaction of the body. Sleep is especially important for relaxation and rest. nervous system. It is a known fact that a person spends about a third of his life sleeping. And here we are in great danger - if we treat our sleep with disdain, sooner or later it will affect our general health and on the state of our health.
Sleep experiments were carried out at different times. It is a known fact that a French court sentenced a certain Chinese man to death for the murder of his wife. The sentence was to deprive the killer of sleep. Three guards were assigned to the Chinese, taking turns replacing each other. They had to wake up the punished murderer. Ten days later, the killer begged: “Execute me, quarter me, shoot me or hang me - just stop this inhuman torment!” This case was reported in a medical journal in 1859. In addition, in the middle of the 20th century, scientists experimentally, with the help of volunteers, found that on the fifth day, a person deprived of sleep has deteriorating vision and hearing, hallucinations may begin, coordination of movements is impaired, attention is scattered, and he is not capable of purposeful activity.
Scientists have discovered that each of us has two sleeps: slow-wave sleep and fast-wave sleep. During the night, slow-wave sleep (lasting 60-90 minutes) is replaced several times by fast sleep - for 10-20 minutes. It is in these short minutes that we dream. We have 4-5 of them per night. When we sleep, the brain is not idle. At this time, metabolism occurs in the brain, nerve cells brains restore their functionality.Not a single minute of such sleep is wasted; each stage is necessary for the complete restoration of the body. But, unfortunately, the majority modern people have already forgotten what healthy sleep means. Various sleep disorders, the wrong approach to its organization - this unsettles even the healthiest people.
So, let's define main role sleep is the rest of the body. In addition, it ensures the organization and processing of information received during wakefulness. And also - it improves your health during illness: not in vain folk wisdom says: “Sleep is the best medicine.”
Dreams
An interesting phenomenon of sleep is dreams. What is it? A dream is a subjective image that appears in a person’s mind. A person usually does not understand that he is dreaming and perceives the dream as objective.
In a dream, a person can see realistic and fantastic events. Dreams can be colored or black and white. You can also see pleasant dream, or it could be a nightmare. Most often it depends on what happened to the person during the day, what worries him. If you don’t remember a dream immediately after waking up, it will be forgotten very quickly. Some people claim that they don't dream at all. Since ancient times, people have tried to learn how to explain dreams, believing that dreams contain information about the future. It is known that sometimes we actually have “prophetic” dreams. Some musicians hear their future compositions in their sleep, and when they wake up, they rush to write down the music with notes. The famous scientist D. Mendeleev also first saw a table of chemical elements in a dream.
3. Third graders and sleep
How much sleep should our third graders sleep? Various scientists and doctors indicate different standards. On average, children should sleep:
from 7 to 8 years – up to 12 hours a day;
from 9 to 11 years old – 10 hours a day (age of 3rd grade students);
from 12 to 15 years old – 9 hours a day.
IN Lately Doctors note an increase in sleep disorders. All these disorders are based on overwork, noisy games, watching late-night movies, and often improper sleep organization. One of the reasons for sleep disturbance in people is a lack of sleep hormone in the body - melatonin, which is produced at certain hours: in adults - from 0 o'clock to 3 o'clock in the morning, and in children - from 23-00 to 3-00. So, at this time we should already be sleeping! All processes in our body occur much more slowly during sleep, including digestion. Therefore, you should take your last meal 2 hours before going to bed so that it has time to digest, but you should not go to bed on an empty stomach. 1-2 hours before bedtime, you need to stop mental activity and physical exercise, since the body and nerve cells tired during the day are further greater load, which leads them to exhaustion. It's threatening having trouble falling asleep, sleep with nightmares.
To analyze whether our children organize their sleep correctly, we conducted a survey among 50 students in grades 3A and 3B. (Annex 1) The results were sad.
The answers to the first two questions showed that 68% of children sleep less than 10 hours, which means they do not get enough sleep. These same children answered that they did not feel sleepy and alert. This means that lack of sleep affects their well-being. The answer to the question about dreams showed that 36% of children dream more often disturbing dreams, 24% have generally scary dreams, and only 32% have good dreams (while 8% of children claim that they do not see dreams). Those children who have disturbing and scary dreams wake up at night – 56% and have difficulty falling asleep – 52%. So, our third-graders not only don’t sleep enough, but their sleep is also not complete. (Appendix 2) Perhaps the reason lies in the fact that they simply do not know what rules need to be followed in order for sleep to bring maximum benefit? This was confirmed by the children’s answers to the corresponding question. Conveying the rules and the need to comply with them is an important task. We found these rules in various sources. They are practically the same. They asked for recommendations from the school doctor, Lyudmila Vasilievna. But it was necessary to verify experimentally that they work. I conducted this experiment on myself.
Experiment
For 5 days I changed my sleep time and falling asleep conditions. This is what happened.
Day 1.
Sleep time is 8 hours. Before going to bed I played on the computer for 1 hour. I decided not to ventilate the room. I ate an apple before bed.
I slept peacefully. In the morning I woke up well. I don't remember the dream. I was not always attentive in class and made mistakes. Not in a good mood.
Day 2.
Sleep time is 7 hours. Before going to bed I watched a movie on TV. I didn't ventilate the room. I ate a hearty meal before going to bed.
I couldn't sleep for a long time. I dreamed about something unpleasant. I didn't want to get up in the morning. At school he was inattentive and got angry about everything. After lunch I felt tired.
Day 3.
Sleep time – 6 hours. Before going to bed I played on the computer again. I didn't ventilate the room. I ate a little before going to bed.
I fell asleep quickly. I woke up once at night. I don't remember the dream. Got up in the morning with difficulty. At school I got tired already in the second lesson. Everything is annoying.
Day 4.
Sleep time is 10 hours. I took a shower before going to bed. I read it a little. I ventilated the room. I drank a glass of kefir.
I fell asleep immediately. Slept without waking up all night. I don't remember the dream. I woke up easily this morning. I felt cheerful. Everything worked out well in the lessons. Mood good all day.
Day 5.
Sleep time is 10 hours. Before going to bed, I played on the computer and took a shower. I didn't ventilate the room. I ate a little before going to bed.
I didn't fall asleep right away. I woke up once at night. I had a terrible dream. Got up easily this morning. Almost everything is fine at school. Tired in the afternoon.
Conclusion: the doctor’s recommendations work! My well-being and performance depend on how I slept. I was surprised by day 4. After three days of lack of sleep, I regained my strength in 1 night! Now we can talk about this and issue a leaflet with recommendations for children and their parents. (Appendix 3)
Conclusion
Our hypothesis was confirmed: our research showed that sleep is a vital necessity. Healthy sleep is the key to a person’s daily activity, high level its performance. A person who sleeps less than normal has a reduced life expectancy, various stress conditions, irritability, fatigue, and illness. internal organs. Health is an invaluable happiness in the life of any person. Each of us wants to be strong and strong and never get sick. And if we follow the rules healthy sleep, then the coming day will be more eventful and joyful.
In the process of work, I found out that when all the requirements necessary for sleep are met, healthy and good sleep. The goal has been achieved and the assigned tasks have been completed. Based on the results of the study, recommendations were made for students, which are presented in the memo. The work has practical significance.
Sleep is only one of the factors affecting health. I became interested in finding out what else our health depends on. Perhaps this question will be the topic of my next research.
