Named the most optimal duration of sleep.
The debate about optimal duration of sleep did not subside for several decades. Someone claims that it is enough to sleep 6 hours a day, someone says something about 8-hour sleep, sometimes called the other figures.
Of course, each person is different, but General rule of sleep, scientists have deduced. According to doctors, these standards – the optimal duration of sleep for an adult.
In particular, a recent study showed that too short and too long sleep contribute to the emergence of chronic diseases. Another study conducted in Korea showed that people who sleep an average of 5 less hours or more than 9 hours, have considerably more health problems, not only physical but also mental.
The most common health problem in people who don’t get enough sleep is a state of anxiety and depression.
More than 30% of people have sleep problems. According to scientific studies, the optimal duration of sleep for a healthy adult is 7 to 8 hours a day.
However, it is not so simple. It is known, for example, that 1-2 hours of sleep a day can replace several hours of sleep at night. Although there is a downside – NAPs can cause insomnia at night.
Athletes should make the amendment – as they perform during a day of hard work and spend a lot more energy than other people, their body needs a longer sleep – 8 to 10 hours a day. Although 7 hours of sleep won’t hurt sports achievements which is also proven by several studies.
There are people who are able to sleep well for 5 or 6 hours. But these people – not more than 5%, the rest need to stick to 7 or 8 hours sleep.
In General, try to sleep at least 7 hours a day but not more than 9 (with rare exceptions) – it is this optimal duration of sleep for the immune system and human health.
