A person spends sleeping a third part of life. It turns out about 25 years – think about this figure! However, this is not so easy to reduce the sleep time. It just will not work. For a full-fledged existence, our body needs about 7-8 hours of night rest. If this figure is much smaller, then there is a rapid decline in mental and physical abilities. However, scientists noticed that during the last century due to rapid technological progress, the average sleep time decreased from 9 to 7.5 hours. Who knows, it’s possible that this is not the limit either.
The longest period of time, during which a healthy person could manage without sleep, was 11 days. The record was set in 1965 by a 17-year-old high school student from San Diego, California. Although history knows an even more impressive case when a Hungarian soldier suffered brain damage due to a head wound and did not sleep for nearly 40 years.
Scientists have found that a systematic lack of sleep can lead to a fairly rapid weight gain (up to a kilogram for a week). This is explained by the fact that the body, with a lack of resources, tries to fill them in any accessible way. Therefore, subject constantly fells hungry, which results in the appearance of extra pounds. Therefore, if you want to lose weight, get enough sleep.
Great people differ from all others not only in their mental abilities but also by certain domestic habits. For example, Leonardo da Vinci used the method of polyphasic sleep: he rested for 15 minutes every 4 hours. Nikola Tesla slept 2 hours a day and Einstein rested a little more – 4 hours a day. This is not a complete list.
Some people claim that they never see dreams. However, this is not true: according to scientists, everyone sees dreams. It is simply we forget the absolute majority of them. After five minutes of wakefulness, 50% of nighttime adventures can no longer be remembered, and if ten minutes have passed, then this figure is close to 90%. Hence the conclusion: if you want to fix your night sleep, put a notebook with a pen or a dictophone next to you to record them.
The first mechanical alarm clock was invented by Levi Hutchins in 1787 in America. He could only wake you up at the same time – 4:00 in the morning. The alarm clock, which can be set up at any time, appeared only 60 years later thanks to the Frenchman Antoine Redier. They were insanely expensive devices then, so ordinary people often used the services of special people who walked the streets and knocked on the windows at a predetermined time.
According to statistics, women sleep about 20 minutes more than men do. Of course, this does not apply to sleep under the influence of tablets from pharmacies such as Soma. As for the quality of sleep, men sleep more restless sleep and wake up more often. But women are 10% more likely to complain about problems with sleep and note the quality of their sleep as unsatisfactory. This can be explained by the fact that women see much more intense and emotional dreams, sometimes turning into nightmares.
