How many hours to sleep at 16. How much sleep do people of different ages need. Definition and rules of healthy sleep

Therefore, it is not in vain that scientists tried to figure out whether it is better for a teenager, and at the same time, when he should go to bed and get up.

Everyone knows that it is difficult to get people aged 15-18 out of bed in the morning. It turned out that this is not just a whim, but a feature of the body at an age when you want to go to bed and wake up later, which is typical for night owls. On average, people aged 17-18 years with a typical schedule of getting up in the morning do not have enough sleep for about an hour and a half, scientists from the USA found after examining 53,689 people over 12 years until 2014.

The best time for teenagers to wake up is 12:30 pm, which in practice is not followed at all. This regime is the complete opposite of the sleep-wake regime for people over 60, who with age turn into “larks”; moreover, they go to bed no later than 11 pm.

Interestingly, already at the age of 19, most teenagers gradually lose the need to wake up in the middle of the day.
As is known, humans have biological ones, the functioning of which is noticeably affected by light. But modern teenagers most often fall asleep with backlights and tablets in which blue light predominates. According to a number of experts, it is possible that the light from them disrupts the functioning of the circadian clock, the chronometer of processes in the body.

Men have been observed to sleep longer than women, perhaps because women see less natural light due to their numerous .

Thus, the time of sleep and rising varies depending on the age, gender and chronotypes of people (“night owls” and “larks”). The study notes that women in the first half of their lives (up to 40 years) are more “early people” than men due to hormonal changes in the body. The average sleep time between 17-18 year olds and 60 year olds was 90 minutes and occurred at 4:30 am and 3:00 am respectively. In reality, older people go to bed no later than 11 pm with eight hours of sleep and wake up at 7 am, but young people do this on average an hour and a half later.

Hormonal changes may be involved in these rhythms, as well as women's family responsibilities, shift work, as well as somatic and mental disorders (depression, for example), bedroom lighting conditions, and passion for something.

The studies were carried out on weekends so that the need to get up for work or other urgent matters was eliminated.

An interesting question is about the spread of people’s chronotypes in the context of “night owls” and “larks”. These differences turned out to be amazing: the difference between them reaches 60% and in some cases can reach 10 hours between different people. (Remember, for example, how I. Stalin worked - he began to work in the late afternoon and strained others for most of the night, involving the same rhythm of the party and state apparatus, where there were different types of people according to their individual characteristics of sleep and wakefulness).

Returning to teenagers aged 17-18, it becomes clear that they are recommended to start school or work no earlier than 8:30 in the morning. The young people studied slept poorly, woke up at night and were sleepier during the day - and this is an unpleasant reality of our time. It is clear who is to blame for this - not only itself, but also social networks growing like mushrooms after rain on the Web. Scientists found that the more teenagers sent messages on social networks, talked, and played before going to bed, the worse they slept.

As an afterword, you need to pay attention to one detail - when changing the clocks to summer and winter time, as is done in most countries of the world, the indicated sleep boundaries require reflection. The point is that we are talking here about more than just one hour. Experts claim that modern time, even without the “summer-winter” movement, has already been shifted by another hour, and go figure out the recommended start and end times of sleep.

Keywords: healthy lifestyle, sleep patterns and duration, students.

Relevance. Human sleep is the main and irreplaceable form of rest and a way to restore the body’s strength and energy resources, especially for a growing body. It is believed that a ten-minute nap restores brain activity by one hour. Sleep patterns and duration are one of the criteria and indicators of a healthy lifestyle and lifestyle.

The educational work of adolescents and students involves a high degree of psychophysical stress and a large amount of time for classes and preparation for them. However, the modern rhythm of life in a metropolis involves unproductive waste of time (traffic jams, queues, etc.). Due to the constant lack of time, students have to sacrifice something. And, more often than not, they sacrifice sleep. The sleep deficit accumulates and is not replenished even on weekends, since various events and intense preparation for the upcoming school week do not provide the opportunity to get enough sleep. My own experience and observations of classmates shows that during classes, especially in the first couples, most of the group openly yawns and sleeps, and in the last couples only the most resilient are present.

The problem of insufficient sleep among adolescents and students is a subject of concern and attention of specialists, because lack of sleep leads to significant health problems. Disturbances in the biological rhythms of the body, sleep patterns and duration lead to a deterioration in the physical and psycho-emotional state, depression, behavioral disorders and aggressiveness of adolescents and students; In addition, lack of sleep impairs memory, thinking, concentration and attention span, reduces the speed of psychomotor reactions, which negatively affects educational results. Pupils and students need sufficient quantity and quality of sleep due to biological maturation and the high educational and psycho-emotional stress that occurs at this stage of ontogenesis.

Problem. The need to obtain new knowledge about scientifically based physiological norms of sleep patterns and duration and real sleep indicators of modern students. We decided to identify answers to the questions: “What are the scientifically developed modern sleep standards?”, “Do teenagers and students follow these standards and recommendations?”

Purpose of the study: to identify compliance of the sleep patterns and duration of adolescents and students with recommended physiological standards.

Research objectives:

1. Identify and study physiological norms and scientific recommendations on sleep patterns and duration for students.

2. To identify the real regime, duration of sleep and well-being of adolescents and students in the learning process.

3. Compare the data obtained with the physiological norms of sleep patterns and duration and suggest ways to solve the problem.

Subject of study - sleep and well-being of adolescents and students.

Research methods: analysis of scientific literature, questionnaires, methods of mathematical statistics.

Organization of the study. The study was organized and conducted at the Kemerovo Institute (branch) of the Russian University of Economics. G.V. Plekhanov at the Department of Physical Education. Adolescents aged 12-14 years (93 people), 15-18 years old (91 people) and students 19-22 years old (93 people) took part in the study.

Research results. To solve the first objective of the study, we analyzed the scientific and scientific-methodological literature, which revealed that there are physiological norms for sleep duration developed for each age category:

· for teenagers (12-14 years old) - 9-8.5 hours;

· for students (15-18 years old) - 8.5-8 hours;

· for students (19-22 years old) - 8-7.5 hours.

Experts believe that adherence to a sleep schedule - the time of going to bed and the time of waking up - significantly affects the quality of sleep, while the time of going to bed for different age categories differs (30 minutes), while the time of waking up is the same for everyone - 7 o'clock in the morning. Experts recommend:

· for teenagers (12-14 years old) “lights out” time - 22.00 hours;

· students (15-18 years old) - 22.30 hours;

· for students (19-22 years old) - 23.00 hours.

To solve the second objective of the study, we conducted a closed survey and analyzed the results by age groups.

Analysis of the results showed that 2% of adolescents in the age group 12-14 years sleep duration is 11 hours or more; 20% - 10.5-10 hours; 30% - 9-8.5 hours; 29% - 8-8.5 hours; 11% sleep 8-7.5 hours; 7% - 7-6 hours. and 1% of respondents sleep less than 5 hours (Fig. 1).

Thus, comparing the results obtained with the recommended norm (9-8.5 hours), we found that only 30% of adolescents aged 12-14 years comply with the norms for sleep duration, and the majority (70%) violate the recommended norms. The identified difference can be explained by high educational and psycho-emotional stress and the body's protective reaction to them.

Analysis of the survey results in the age group 15-18 years old showed that more than 5% of respondents sleep 11 hours; 10.5-10 hours - 7%; 9-8.5 hours - 8%; 8.5-8 hours 20%; 8-7.5 hours 14%; 7-6 hours - 43% and less than 5 hours - 3% (Fig. 1).

Analyzing the results of the study, we found that only 20% of adolescents aged 15-18 years comply with the norms for sleep duration (8-8.5 hours), and the majority (80%) violate the recommended norms. The reason for this may be adolescence, new entertainment, increased educational and household workload, part-time work in the evening or at night.

Students aged 19-22 spend the following amount of time sleeping: 11 hours or more - 2%; 10.5-10 hours - 6%; 9-8.5 hours - 7%; 8.5-8 hours - 13%; 8-7.5 hours - 10%; 7-6 hours - 44% and less than 5 hours - 18% (Fig. 1).

Analyzing the results of the study, we found that only 10% of students aged 19-22 years comply with the norms (7-8 hours) of sleep duration, and the majority (90%) violate them. This is due to the high pace of life of students, heavy academic and everyday workload, and part-time jobs.

Picture 1. Sleep duration of teenagers and students

The results of the answers to the questionnaire question “What time do you go to bed?” allowed us to identify the sleep patterns of the respondents. Analyzing the answers in the age group of 12-14 years, we received the following results: they go to bed at 21.00 or earlier - 11% of respondents; at 22.00 - 25%; at 22.30 - 31%; at 23.00 - 19%; at 24.00-01.00 - 12%; at 02.00 and later - 2% (Fig. 2).

By correlating the data obtained with physiological norms, we found that 25% of adolescents aged 12-14 years observe a sleep schedule, and the remaining 75% violate it.

Analysis of responses from the age group 15-18 years old showed that 3% go to bed at 21.00 or earlier; at 22.00 - 13%; at 22.30 - 15%; at 23.00 - 47%; at 24.00-01.00 - 18%; at 02.00 and later - 4% (Fig. 2). Comparing the data obtained with physiological norms, we found that only 15% of 15-18-year-old respondents comply with the norms, and the remaining 85% violate them.

Analysis of the responses of students (19-22 years old) showed that: they go to bed at 21.00 and earlier - 0; at 22.00 - 4%; at 22.30 - 6%; at 23.00 - 10%; at 24.00-01.00 - 56%; at 02.00 and later - 24% (Fig. 2). Thus, only 10% of students maintain a sleep schedule, and the majority (90%) cannot comply with it.

Figure 2. Sleep patterns of adolescents and students

Analysis of responses to the survey question “How do you rate your well-being during the school day?” (Fig. 3) showed that the well-being of adolescents and students varies greatly.

In the age group of 12-14 years, only 5% of respondents answered “great, I don’t want to sleep, I’m determined to study”; 55% - “I feel good”; 37% - “satisfactory, but I feel weak, want to sleep” and 3% chose the answer “I feel bad, I want to leave class and get some sleep” (Fig. 3).

Analysis of responses in the age group 15-18 years old showed that 0% felt great, slept well and were motivated to study; “I feel good” - 45%; “satisfactory, but I feel weak and want to sleep” - 48%; “I feel bad, I want to leave class and get some sleep” - 7% (Fig. 3).

The student age category (19-22 years old) also did not feel great, had enough sleep and were in the mood to study (0%); while 31% noted that “I feel good”; 35% - “satisfactory, but I feel weak and want to sleep”; 34% - “I feel bad, I want to leave class and get some sleep” (Fig. 3).

Figure 3. Well-being of adolescents and students during the school day

conclusions

1. Sleep is an obligatory and complete form of rest. For the age group 12-14 years old, the mandatory and necessary sleep norm is 8.5-9 hours, 15-18 years old - 8-8.5 hours, 19-22 years old - 7.5-8 hours. Experts recommend following a sleep schedule and its duration; exclude active physical and mental activity, drinking stimulating drinks, smoking, overeating before going to bed; do not sleep during the day, observe the conditions for proper sleep - take a walk before going to bed and perform hygiene procedures; Maintain the optimal temperature in the bedroom (18-20˚), turn off communications and TV.

2. The duration of sleep of adolescents and students aged 12-22 years differs significantly from physiological norms: 20% comply, and 80% do not adhere to the recommended norms for their age group; At the same time, 57% do not get enough sleep, and 23% of teenagers and students oversleep.

3. 17% of adolescents and students aged 12-22 years follow a sleep schedule, and 83% violate it; At the same time, 12% go to bed earlier than the recommended hour, and 71% much later, which disrupts their biological rhythms and well-being during the school day.

4. Due to non-compliance with the norms and sleep patterns of adolescents and students, their well-being during the day is generally between “good” and “satisfactory” and worsens with increasing age. Only 2% of respondents feel great during the school day, while 14% of respondents feel unwell.

1. Plan your educational and household workload, attending entertainment events and part-time work, taking into account your sleep schedule. Set priorities (health, study) and remember that without proper sleep you will not be able to absorb educational material and cope with academic loads.

2. Gradually bring your bedtime closer to the recommended time, remember that sleeping within an hour before midnight and waking up at 7 o'clock corresponds to a person's biological rhythms, which helps restore strength and maintain health.

3. Try not to sleep during the day, this disrupts your bedtime in the evening and negatively affects the duration of night sleep and your well-being during the school day.

Temperature of water during hardening

Contrary to popular belief, hardening does not require low temperatures. It requires temperature contrast. Cold causes blood vessels to constrict; heat causes them to expand. And the main thing in hardening is vascular training.

Teenagers are very active: they study diligently, attend extracurricular activities, play sports, are interested in creativity, communicate with friends, watch movies... To restore the energy expended after physical and mental stress, the body needs sleep.

Lack of sleep quickly affects a teenager’s condition: he quickly gets tired, becomes lethargic, inattentive, and irritable. His academic performance deteriorates, difficulties appear in communication, and interest in his former hobbies disappears.

Therefore, proper sleep patterns for teenagers are of great importance.

What time should a teenager go to bed?

The daily sleep requirement is approximately 9 hours for adolescents 10-14 years old and 8 hours for adolescents 14-18 years old. If mental and physical stress daily exceeds the norm, sleep time can be increased to 10 hours.

Based on these indicators, you can create the right sleep schedule for teenagers.

What time should a teenager go to bed? If in the morning he has to wake up at 7.00, then he should fall asleep no later than 22.00-23.00. You should not give up a short daytime sleep - just 1 hour (for example, 15.00-16.00) will help make up for the lack of sleep at night and restore the strength expended in the first half of the day.

Teenagers are night owls and early risers

“Larks” and “owls” are common types of human biorhythms. “Larks” wake up easily in the morning, are active in the first half of the day, and fall asleep before midnight. Owls have difficulty waking up in the morning. Their peak activity occurs in the afternoon, falling asleep occurs after midnight.

Most people are “early people” - waking up early and falling asleep early is characteristic of the human body. Those who call themselves “night owls” are most likely simply accustomed to this lifestyle.

Teenagers are especially guilty of this. Their daily schedule is occupied not only with schoolwork, but also with communication with friends, games, walks, and hobbies. Not having time during the day, teenagers transfer some of their work to the evening and night. Gradually, the body gets used to falling asleep late, but the problem of waking up early appears.

What to do if your teenager goes to bed late?

Parents often find teenagers reading books, smartphones or computers long after midnight. There is no time to compensate for the lack of sleep - you have to get up early in the morning for school.

What should parents do if their teenager goes to bed late?

• Explain for a teenager, the importance of a good night's sleep - to improve school performance, sports achievements, and creative results;
• Reduce daily loads or correctly distribute school and extracurricular activities throughout the day so that the teenager does not have to transfer some of his activities to the night;
• Limit computer games, surfing the Internet, watching movies, listening to music;
• Exclude energy drinks (including cola), strong coffee and tea at night;
• Encourage short naps during the day and timely (no later than 23.00) falling asleep at night;
• Avoid long sleep on weekends.

Sleep plays an important role in daily routine. In the light of modern ideas, sleep is considered as an active activity of the body, only organized differently than daytime life. Human sleep is the main and indispensable form of rest and a way to restore strength and energy resources of the body, especially for a growing organism. Sleep patterns and duration are one of the criteria and indicators of a healthy lifestyle. The problem of insufficient sleep among students is a subject of concern and attention of specialists, because lack of sleep leads to significant health problems.

The purpose of our study is to identify the correspondence of students' sleep duration to recommended physiological standards. Objectives of the study: 1. To study the effect of sleep on human health and performance. 2. Study the physiological norms of sleep duration and compare them with the sleep duration of students.

Object of study: students of TI (f) NEFU. Subject of research: sleep and its duration. The study involved 178 1st-5th year students studying full-time at the Technical Institute (branch) of NEFU.

Sleep is an effective way to relieve mental and physical stress. It is not without reason that a weakened, sick person or someone who has been in extreme situations for a long time is able to sleep for a long time. This is a physiological defense of the body; the need, like treatment, is determined by complex psychophysiological processes. As noted by I.P. Pavlov, sleep is not just rest, but an active state of the body, which is characterized by a special form of brain activity. In particular, during sleep, information accumulated by a person over the previous time is analyzed and processed. If such sorting was successful, then the brain is freed from excessive information accumulated the day before and is again ready to work. Thanks to this, a person’s neuropsychic state is normalized and performance is restored. Sleep facilitates programming processes in the brain and performs a variety of other functions. During sleep, changes occur in the entire vital activity of the body, energy consumption decreases, systems that have suffered overload (overwork or painful changes) are restored and begin to function. Sleep eliminates fatigue and prevents depletion of nerve cells. Energy-rich phosphorus compounds accumulate, and the body's defenses increase. Chronic lack of sleep contributes to the so-called disorder - the appearance of neuroses, deterioration of functionality and a decrease in the body's defenses.

Disturbances in the biological rhythms of the body, sleep patterns and duration lead to a deterioration in the physical and psycho-emotional state, depression, behavioral disorders and aggressiveness of adolescents and students. In addition, lack of sleep impairs memory, thinking, concentration and attention span, reduces the speed of psychomotor reactions, which negatively affects educational results. Students need sufficient quantity and quality of sleep due to biological maturation and the high educational and psycho-emotional stress that occurs at this stage of ontogenesis.

Sleep is closely related to the body's circadian rhythm of alternating day and night, light and dark. During sleep, the energy and functional reserves of the human body are renewed and accumulated. People sleep for about a third of their lives. Events and activities during the day affect how you sleep at night and how you feel the next day. The more a person is awake, the more sleep he needs. Sleep performs a so-called homeostatic function, relieving the feeling of fatigue.

Sleep is associated with the production of several very important hormones. This is why lack of sleep can cause health problems. Melatonin is a hormone that protects against stress, premature aging, improves immunity and prevents cancer. Up to 70% of its daily requirement is produced during sleep. Its production begins at dusk, reaches a peak in the dark - from midnight to 4 am, and falls by dawn. Urban residents have problems with melatonin deficiency more often than rural residents due to the strong illumination of cities at night. Somatotropic hormone (growth hormone) slows down aging, improves memory and regulates the activity of the nervous system. Its production peaks at the beginning of the night, 2-3 hours after falling asleep. Sleep disturbances lead to a decrease in the production of growth hormone. Grelini leptin: the first is responsible for appetite, the second for the feeling of fullness. Those who do not get enough sleep increase their appetite, and therefore their weight. Therefore, those losing weight need to improve their sleep. Studies have shown that women who get enough sleep lose weight 2 times faster than those who don’t get enough sleep.

The average duration of a person's sleep usually depends on numerous factors: ranging from age, gender, lifestyle, diet and degree of fatigue, to external factors (general noise level, location, etc.). The duration of sleep in newborns, adults and the elderly is 12-16, 6-8 and 4-6 hours per day, respectively. Also, in spring and summer, with a sedentary lifestyle, with a small amount of carbohydrates in meals, and also outside the city, the normal duration of sleep can be only 5-6 hours, and with sudden loud sounds (or during loud music) and bright lighting it is possible even a complete lack of sleep. In general, in case of sleep disorders, its duration can range from several seconds to several days. There are also cases that an adult needs 12 hours to get enough sleep or recover from hard work and sleepless nights. Sleep duration of less than 5 hours (hyposomnia) or disturbance of physiological structure are considered risk factors for insomnia. Starting from the age of seven, the sleep norm is 10 hours. In adolescence (12-18 years) - about nine hours. From the age of eighteen, a person is considered an adult and his sleep norm is 8 hours. As you age, your sleep requirement gradually decreases and by the age of 60 it reaches the level of six hours of sleep per day. It is generally accepted that students need to sleep 7-9 hours a day. The most physiological period is the period from 23 to 7-8 am. .

The survey we conducted made it possible to find out that 20.7% of the surveyed number of students sleep lasts 8 hours, 24.7% - 5 hours, 17.9% of respondents - 6 hours, 16.3% of students sleep 7 hours, in 7% of students sleep for 4 and 9 hours, and 5% of students sleep for 10 hours.

Based on the data obtained, we can conclude that half of the students experience lack of sleep.

Thus, sleep is a physiological defense of the body from excessive information, a period of restoration of the neuropsychic and physical state. Sleep has a therapeutic effect of maintaining the body in health and helps to increase a person’s vigor and performance. The physiological norm of sleep for people of student age is 7-9 hours. Based on our analysis, we can state that only 44% of the students surveyed had normal sleep duration. 49.6% of respondents do not get enough sleep, 5% oversleep. In this connection, it is necessary to study the reasons for lack of sleep in students and develop valeological recommendations.

Scientists have found that teenagers aged 14 to 18 years need to sleep 8.5-9.5 hours. During sleep, children rest their body, brain and restore strength after physical and mental stress. If a child does not get enough sleep, he will soon become lethargic, irritable and inattentive. Its performance will decrease by 30%.

How much sleep does a 14 year old teenager need?

There is no single sleep standard for teenagers. Research by American and Swedish scientists has proven that children of a certain age have different needs for rest.

Sleep patterns in adolescents aged fourteen during the day and night

Children don't think about the fact that lack of sleep can lead to serious problems. 14-year-olds should have the same sleep schedule every day.

Teach your child to go to bed at 10-11 pm and wake up at 7 am.

And when a tired teenager comes home from school, he can regain his strength by sleeping between 15:00 and 16:00.

Duration of sleep in fourteen-year-old children during the day and night

Of course, teenagers should have not only night sleep, but also daytime sleep. At night, 14-year-olds may need 8 hours of sleep instead of the required 9.5. But soon your child may become nervous and tired.

Children should spend 30-45 minutes on daytime rest. This time is enough to relieve fatigue, gain strength and go to additional classes or training.

Sleep disturbance in a 14 year old child: causes

• Doctors are confident that modern children are disrupting their sleep patterns because they spend a lot of time at the computer or TV, watching movies or TV shows.
• In addition, many teenagers fall asleep with headphones in their ears while listening to music tracks. Limit your child from these activities before bed.
• Drugs containing caffeine that stimulate performance can disrupt sleep.
• Poor sleep can also be caused by illness, such as breathing problems. It is worth seeing a doctor to find out if your child is sick.
• In addition, a hard sleeping bed or a stuffy room can affect your sleep.

A 14-year-old child constantly sleeps: why?

The main reason in adolescence is- both mental and physical. Many parents complain that their children sleep a lot during the day when they come home from school. There are frequent cases when 14-year-olds wake up for dinner and then go to bed to sleep until the morning.

Also, the reason for the constant desire to sleep can be disease . It can go unnoticed.

For example, some diseases of the ENT organs cause lethargy, malaise and occur without high fever. It is worth seeing a doctor and taking the necessary tests.

Comment from doctor Anna Yuryevna Pleshanova, pediatric neurologist:

The main criterion for adequate sleep is the quality of wakefulness.

If a teenager, despite the small number of hours of sleep, gets up easily in the morning, feels normal during the day, does not experience drowsiness or fatigue, successfully copes with educational and sports loads, and has a good memory, it means he has enough sleep.

If the teenager does not meet these criteria, it is necessary to increase the duration of sleep either by going to bed earlier in the evening, or, if possible, by sleeping 40 minutes to an hour during the day.

How much sleep does a 15 year old need to sleep?

Children at the age of 15 are very active; they attend not only school classes, but also clubs. In order not to lag behind in development and to restore physical and mental abilities in time, adolescents must sleep.

Let's consider how the rest process should proceed for 15-year-olds.

Proper sleep schedule for children aged 15

A 15-year-old child completely refuses daytime sleep. But there are teenagers who relax at lunch when they come home from school. Daytime sleep occurs approximately from 15 to 16 hours.

A proper night's sleep schedule varies from 10-11 pm to 7 am. As a rule, children wake up for school at this time.

How long should a teenager sleep during the day and at night?

The duration of daytime sleep depends on the load. However, children should not sleep for more than 30-45 minutes. It has been established that this time is enough for rest.

And the duration of night sleep is less than that of 14-year-olds, although not by much. 15-year-olds should sleep 9 hours at night.

Causes of poor sleep in a child aged fifteen

Sleep disturbances in a 15-year-old child can begin for several reasons.
