Officially, doctors believe that a person should sleep about eight hours a day. According to doctors, if an individual spends more or less time on night rest, this may negatively affect his health. However, many researchers still adhere to a slightly different point of view. In their opinion, the answer to the question of how much sleep a person should have is strictly individual. In this case, everything depends primarily on physical features the body of a particular person, his character and personal qualities.

A good night's rest: two examples from history

It is believed that active people, sanguine and choleric people usually need less time to sleep than phlegmatic and melancholic people. Napoleon, for example, when asked how much sleep a person should sleep a day, once answered: “4 hours for a man, 5 hours for a woman and 6 hours for an idiot.” Leonardo da Vinci never spent any time sleeping at night. To rest, he simply went to bed for 15-20 minutes every three hours. That is, this great person Spent no more than 3 hours a day on sleep.

Scientists have already conducted a very interesting experiment in our time. They found a volunteer who agreed to try Leonardo da Vinci's system on himself. For six months this man slept for 20 minutes once every three hours. At the end of the experiment, it was noted that the biological functions of the subject were absolutely not affected. The mental activity of this person also remained normal during the experiment.

So how much sleep do you need?

Finding the answer to this question for yourself will not be difficult. First, you just need to try to sleep for a couple of weeks as doctors advise. That is, strictly 7-8 hours a day. Although the time needed to sleep is an individual concept, these figures can be considered an average. Most people need this much time to get a good night's rest.

To determine the optimal sleep time, you should carefully monitor the condition of your body throughout the two weeks of the self-conducted experiment. If, after spending 7-8 hours sleeping, you feel lethargic, have a headache, etc., simply try increasing or decreasing this time. In the end, by experience you will definitely be able to determine how many hours you need for a good night's rest.

How much sleep should a person have per week?

If a person needs to spend approximately 8 hours sleeping per day, then it turns out that he needs to sleep 7x8 = 56 hours per week. If you personally have to spend more or less time on your night's rest, you will just need to perform the same simple calculation yourself.

In any case, it’s still worth calculating the time needed for a night’s rest not by weeks, but by days. If, for example, on Monday you sleep for 3 hours at night, and on Tuesday you try to “get” the missing time by sleeping for 13 hours, you still won’t get proper rest. The fact is that one of the absolute conditions for a cheerful mood during the day is adherence to a sleep schedule. That is, no matter how many hours you need to rest at night, you should try to go to bed and get up at strictly defined hours.

Life is getting faster and faster, its rhythm makes us more and more active, forgetting about ourselves and our own health. In the rush to get everything done, people often forget how much sleep they need per day to stay healthy. Sometimes, trying to be in time for everything and everywhere, people devote less and less time to nutritious food, interrupting with fast foods and food “on the go”, they forget about normal mode and daily routine. There are no longer enough hours in the day, and something has to be sacrificed...

One of the most necessary elements human life, along with air, water and food, is sleep

Often this is time to sleep. And then the consequences of this rhythm of life begin. At the age of 30, people of our generation already have a whole “bouquet of diseases” - arrhythmia, headaches, syndrome chronic fatigue and other. You need to understand that we pay for lack of sleep with our health.

Any problems with lack of time can be solved with proper time management and, ultimately, prioritization. After all, no material wealth can replace youth, beauty and health. Systematic lack of sleep is equivalent to several lost years of your life.

How many hours does a person need to sleep?

With the invention of the light bulb and electricity, humanity has the opportunity to not depend on sunrises and sunsets, we can change day and night, we can not take into account the duration of the dark time of the day - this moves us in development and, at the same time, destroys us... Even before Thomas’s invention Edison - the electric light bulb - people slept an average of 9 hours a day. Now this figure is rapidly decreasing and reaches only seven hours out of the 24 we have.

Think about how many hours you sleep a day? Do you maintain a sleep schedule? If yes, then you have an unaffordable luxury in our time. Most people try to combine work, study, family, night parties, and simply waste time watching TV series - this gradually steals the time that should have been devoted to sleep.

Sleep norm

Modern scientists are increasingly coming to the conclusion that there is no single standard of night rest for all people

How much sleep a person needs is an individual and average indicator at the same time. Since childhood, we have heard that we need to sleep 8 hours. So, a person needs AT LEAST 8 hours of sleep per day. This is the minimum that ensures normal functioning body and maintains health. This is our sleep norm. Individually, a person may need a little more time for rest and recovery.

What time should you go to bed?

As already mentioned, thanks to our independence from daylight hours, people can create their own regime. But the point is that The biological clock, laid down to us by nature, is not so easy to deceive. The point is that it is in dark time day - at night, the production of a hormone vital for humans - melatonin - occurs. Melatonin is actively produced from midnight until 2-3 am. Accordingly, a person must sleep at this time, otherwise the lack of melatonin will negatively affect the body’s condition. Melatonin helps keep almost all body systems in order - from the immune system to the cardiovascular system. Also, melatonin helps maintain youth and beauty.

Based on this, it is normal for human body There should be a sleep schedule in which you need to go to bed at 22-23 o'clock and wake up at 7-8 o'clock in the morning. Compliance with this regime and natural biorhythms will have a positive effect on general condition body.

Owls and larks

According to their sleep patterns, all people are divided into night owls and larks.

The excuse that there are types of people: “night owls” and “larks” is refuted by many scientists, since, initially, the biological clock is inherent in every person in exactly the same way. With the onset of darkness, the body should rest, and during the daytime it should be awake and active. “Owls” are people with a broken routine that needs to be corrected.

Consequences of lack of sleep

Everyone knows that the lack of adequate sleep has a bad effect on a person’s condition. I think each of us has encountered feeling unwell after sleepless night. Inability to concentrate, slight weakness, temporary memory impairment are external signs lack of sleep. What happens to our body due to lack of sleep?

Sleep is restoration for the body, rest necessary for the quality functioning of all systems. In case of lack of sleep, malfunctions and disruptions in the functioning of body systems occur. First of all, lack of sleep affects cardiovascular system, and also reduces brain activity, leads to stress and chronic fatigue syndrome. Memory and attention deteriorate and the risk of heart attacks and strokes develops.

A consequence of lack of sleep is also a violation hormonal levels, and this definitely leads to a deterioration in the functioning of the body and negatively affects the appearance.

The risk of developing terrible oncological diseases, from which modern medicine never invented a cure, increases significantly due to lack of sleep.

And most importantly, life expectancy becomes shorter with lack of sleep.

Folk sleeping pills

Since ancient times, people have been looking for various sleeping pills

Many people suffer from insomnia, or mild sleep disturbances; in other words, they have difficulty falling asleep and their sleep is quite restless. In this case, you need to consult a doctor and find out the causes of the disorder. You don’t have to immediately run to the pharmacy for medicine, you can try folk remedies, which are much more environmentally friendly.

Since childhood, we have heard that you need to ventilate the room before going to bed - this is really good, a remedy for insomnia, and even better a short walk will have a positive effect on the quality of sleep.

To sleep better, you can drink a glass of hot milk at night. Or, take a warm bath with pine extracts. Just a couple of drops fir oil will have a beneficial effect on the ability to fall asleep and are great for preventing colds.

What to do before bed to fall asleep quickly

It is recommended to drink before bed herbal teas that calm you down nervous system. The most common herbs that grow in our country are mint, chamomile, motherwort, valerian, and lemon balm. Tea made from these herbs will relax you and make it much easier to fall asleep.

You can also make a small pillow by filling it with the above herbs and adding a couple of drops essential oil lavender. This pillow should be kept on the bed next to your head; the smell of herbs and oils is soothing and has a great effect on sleep.

Everyday healthy sleep- a physiological necessity for any person. It is necessary to take care not only about the duration of sleep, but also about its quality. Full-fledged. Nowadays everything more people experience difficulties in organizing healthy sleep due to leading a certain lifestyle.

Most scientists agree that lack of healthy sleep has the most adverse effect on health.

In addition, numerous studies suggest that women should sleep slightly longer than men.

How many hours do you need for healthy sleep?

How many hours does healthy sleep last for an adult? Some physiologists say that healthy sleep for an adult should last about 8 hours. It is this duration that makes it full and healthy. However, there is another opinion that the duration of good healthy sleep is different for age groups. So, for people aged 20-50 years, sleep should last at least 8 hours. For older people, due to physiological characteristics, 4 hours of sleep is enough.

It is important to observe the start time of sleep. It is believed that it should begin before midnight, ideally from 22 o'clock. The quality of sleep “before midnight” is several times different from sleep “after”. In addition, not only the total duration of night sleep is important, but also its continuous duration. Thus, data from the World Health Organization suggests that it is more beneficial to sleep 6 hours in a row than to wake up for 8 hours. The following fact is interesting - scientists say that women need to sleep at least 8 hours, while a man needs 7 hours for healthy sleep. This is associated with the increased emotionality of women.

In order for healthy sleep and a person’s biorhythms not to be disturbed, it is necessary to go to bed at the same time, no matter whether it is a working day or a weekend. For healthy sleep you need to create suitable conditions, in particular, a suitable temperature in the room and the absence electric light in it. In addition, there is the so-called law of three eights, according to which healthy sleep should last 8 hours, the length of the working day should be 8 hours, and rest, accordingly, should also be 8 hours.

Thus, systematic disturbances in sleep duration will not have the best effect on a person’s well-being and performance. It is unacceptable to get enough sleep on weekends, increasing the duration of sleep by several hours. After all, the regime is important. Studies have shown that the lack of healthy, full sleep reduces immunity, impairs memory and attention, and leads to cardiovascular diseases, chronic headaches, obesity and depression.

With all this, we must not forget about individual characteristics the body of every person. After all, if one person needs 8 hours to recover, then 4-5 is enough for another. Therefore, it is, of course, advisable to follow the recommendations, but if you adhere to individual treatment your well-being and health do not suffer - then why not continue to live in the same way?
