Sleep 6 hours: what is its harm
Scientists learned in 2004 that six hours of sleep is harmful. Then an experiment was conducted at the University of Pennsylvania with the participation of 48 people. For the duration of the experiment, their sleep was reduced to 4, 6, and 8 hours. Some people did not sleep at all for two days – but there is no need to talk about the dangers of such an approach.

3. Six hours of sleep helped to maintain good mental abilities until the tenth day. After there was a sharp deterioration – and the rates were the same as in sleep-deprived people.
Thus, sleeping for six hours a day is equal to two days of sleep. At the same time, people did not feel sleepy, everything, in their opinion, was normal.
Sleep longer than 7 hours – harmful or beneficial
If the minimum sleep time is supposed to be seven hours, is it possible to sleep longer? Until recently, everyone was sure of this. But recent studies have shown that such a long sleep leads to a deterioration in attention and memory. That is, the optimal amount of time for sleep – exactly seven o'clock.

According to research, people who get seven hours of sleep have a low threshold for morbidity and mortality. But exceeding this indicator by just an hour significantly increases the risks. The study, which proved this fact, involved 160,000 people. The data also suggests that seven hours of sleep increases cognitive function. But the eight o'clock is already beginning to oppress them. That is, too much sleep is just as harmful as its lack.
How much sleep to get enough sleep and be healthy
Sleep research is ongoing, all facts are being tested. Therefore, while you can be guided by the advice of experts who advocate a middle ground. Lack of sleep is as harmful as too much sleep.
But the norm for every person – its. And, above all, there are differences in the age of the sleeper:
• adult healthy people should sleep at least 7 hours, maximum – 9;
• seven or eight is enough for the elderly;
• schoolchildren must rest for at least ten hours;
• teenagers can sleep from 9 to 10 hours.
In case of severe fatigue, stress or illness, the body needs more sleep. It is also considered that the body itself sets the norm for itself – and if you wake up on your own, then the body has already rested and "wakes up" you.
If the sleep mode is disturbed – you don't get enough sleep, you don't sleep well, you can't fall asleep – this is fraught with many problems. For example, due to a lack of sleep, the risk of cardiovascular disease, obesity, and diabetes increases. Therefore, avoid such situations:
1. Sleepless nights – one such night can negatively affect the body, after which it will recover for two weeks.
2. No sleep mode – if you go to bed at different times, this leads to hormonal disorders. As a result – obesity, hypertension.
3. Intermittent sleep – students often sin in preparation for the session. If you sleep for a couple of hours, then work and then fall asleep again, then the body is depleted.
As you can see, sleep for 6 hours is just as harmful as, for example, 10 hours, but with nightly gatherings, intermittent or no sleep. Therefore, try to go to bed at the same time, do not stay up after midnight, try to sleep for at least seven hours.
