  1. The need for sleep is a genetically determined indicator that is individual for each person. For most people, it is from 7 to 8 hours, but this is not the norm for everyone! In general, the personal need for sleep varies from person to person in a wide range and can range from 4 to 12 hours!

    People who sleep 4-6 hours are called short sleepers. Those who need 7-8 hours – people with a normal need for sleep. Finally, “dormice” who spend 9-12 hours in bed are long-sleepers.

    In general, only a relatively small number of people get enough sleep in 6 hours. The rest, if they are forced to sleep so much on weekdays, experience signs of sleep deprivation, and then sleep off on weekends. Not a very useful habit, which over time can lead to the so – called social jetlag-knocking down the biological clock, which in turn causes insomnia.

    Try to sleep according to your natural needs and may you have a good night's sleep!

  2. Sleep standards are conditional – someone needs to sleep 6 hours, someone 8. They depend on many factors: gender, age, lifestyle, and others. After all, babies sleep for 18 hours, and young people can sometimes not sleep at all at night.�

    To bring some order to this issue, experts set the norms of sleep. We emphasize once again that they are conditional. But in principle, we can say that between the ages of 16 and 64, that is, for most of your life, six hours of sleep is the acceptable minimum.�

    You can read about sleep standards and the harms of lack of sleep in the article on our website.�

    And please note that the article contains recommended standards. In fact, unfortunately, we sleep less.

  3. True, 5 is enough, but periodically the brain “sleeps off. For example, a week of 5-6 or less hours, then 7-8 hours. As I got older, I started sleeping more. Although the sleep period was not affected in any way. Recently, the body itself somehow changed from a sleep mode from 5 am to 12 pm, on the contrary, from 11-12 pm to 4-5 am, which is better yet I don't know .

  4. There is a lot of controversy on this topic, however, the point is put by the 2015 National Sleep Foundation study. They proved in large samples that it is harmful for an adult to sleep less than 7 and more than 9 hours. Otherwise, the risk of depression, decreased sexual desire, premature skin aging and other disadvantages increases.

    Here is the full table in Russian:

    There is a small caveat, of course. There is a polyphasic sleep or “nap” during the day. In this case, you can sleep at night and 6 hours. But to do this, you need to go to bed during the day for no more than 20-30 minutes, so as not to fall into a deep phase. Otherwise, your body will assume that it's already night and you'll wake up even more exhausted than you were before the day's sleep break.

    In short, if you want to reduce the time to sleep, like Salvador Dali, be careful. This can seriously affect your health.

  5. Don't know…I sleep 2-3 hours at night, approximately 1-1. 5 hours in the afternoon. I feel great, I get up easily in the morning. If you are busy with active activities during the day, then I can neglect daytime sleep.

  6. Yes. some geniuses generally slept for an hour or 1.5 hours a day .Sleep deprivation monitoring the schedule of your phases and that's it(:

    Well, the quality of sleep is more important than quantity))

  7. There are no scientific studies that prove that reducing sleep time improves well-being or quality of life. There are also no studies that clearly show that a lot of sleep is harmful: most often it is just a confused cause and effect, when the disease causes drowsiness, and not sleep causes illness.�

    In short, the need for sleep is a very individual thing. I know a person who goes to bed at 9 pm and gets up at 4-5 am all his life. And she is very happy, she is always cheerful in the morning and advises everyone to have such a schedule. I honestly tried to try, but the problem is that I can only go to bed at 9 pm if I haven't slept for 24 or more hours before. And I can't get up at five o'clock in the morning and never get up at all. Under no circumstances. So don't try to fight yourself. If your body needs 10 hours of sleep to get enough sleep, take it and don't hurt yourself.

    How much sleep do you need

  8. Research in this area is extremely insignificant, so far it is impossible to say with accuracy what exactly will happen from a certain amount of sleep, most likely everything is strictly individual and depends on you, on average, it is desirable to sleep 6-8 hours, but with time, less than this, it is already more interesting. Since I am engaged in science, I keep my schedule at the level of 3-4: 30 hours a day and Some people, such as Tesla, used polyphasic sleep tactics, thus spending only 2 hours a day on sleep, and he lived healthy until almost 90 years. It is impossible to say exactly what will happen, perhaps even a lot depends on your attitude to it, recently even studies have shown that the idea that stress harms you, it can really harm and cause various diseases of the heart system, which then cause early death, but if you convince yourself that this is a protection and help of the body during dangers or unusual something, then even the risk of death from diseases caused by stress decreases, and this decrease is far from fluctuations in statistics, (TED to help you or libraries with research), that is, the effect is approximately similar to the placebo effect, which is very interesting, i.e. the dependence on your mood may be greater than you even imagine.
