No matter what kind of people it is, it is necessary to ensure adequate sleep, and it is recommended to develop a regular habit of work and rest, which can ensure full energy and help prevent the occurrence of various diseases.

Sleeping more than four hours is very bad for the body, sleeping 8 hours is the normal sleep time, but the sleep time varies from person to person, usually adults over 18 years old, sleeping 6-8 hours is the normal sleep time. If you wake up after 8 hours without feeling tired, you can increase the sleep time appropriately, but not too long. The average sleep time of each adult is hours, each person's sleep cycle includes two stages of deep sleep and light sleep, it usually takes about 30 minutes to enter the deep sleep stage after falling asleep, deep sleep and light sleep are alternated in the daily sleep process, usually need 4 cycles to ensure that the brain gets a better rest.

From a health point of view, sleeping for four hours is not good for your health. The latest research has found that adults should sleep a little more than 7 hours, which is the most suitable for the human body and is beneficial for longevity. It is generally believed that more than 80% of adults sleep for about hours a day, teenagers need more, teenagers need about 8-9 hours, and children need more, children need 10 hours of sleep.

But this is only for most people, there are individual differences. Some people take short sleeps and only need 4-5 hours of sleep every night. These 4-5 hours of sleep will not cause any physical discomfort to these people, so there is no need to force 6-7 hours, or 7-8 hours of sleep, so that they will feel uncomfortable.

Some adults may need to sleep for a longer period of time, perhaps 9-10 hours. This is a long sleeper, accounting for about 1%-3% of the population. So how long you sleep depends mainly on whether you can sleep well, and you can be clear during the day, and you don't feel tired or sleepy, so you don't have to worry too much about how long you have to sleep.

From a health point of view, sleeping 4 hours a day is not good enough for the body. Because for most people's physique, 4 hours of sleep is far from enough.

Therefore, if you want to make yourself well, you must not sleep for 4 hours, and it is best to sleep for about 7 or 8 hours, so that your body can be better.

And in fact, the sleep needs of ordinary people are actually more than 7 hours, sometimes even 8 hours and 9 hours, and a small number of people can sleep for very little time, but they are still very energetic.

And in fact, everyone's sleep time is different, some people are the kind of long sleepers, but some people are short sleepers. Long sleepers need to sleep for seven or eight hours, or even 10 hours, to be energetic.

And those who wait for sleep may actually be able to sleep for only three or four hours to achieve energy efficiency. Therefore, there is a big difference between the two, and most of the people who can say that they can sleep for 4 hours are actually a kind of short sleeper, or he has made himself a short sleeper through some acquired exercise.

But the vast majority of people are not such short sleepers, that is to say, if you only sleep 4 hours a day, your body will not be able to stand it, and even collapse, so it is still not recommended to sleep 4 hours a day.

Because even if you can free up a lot of time to do more things, but for us ordinary people, health will be more important, if 4 hours a day, for most people will lose a lot of physical health, so 4 hours of sleep is not enough, it is better to let yourself sleep a little more, let yourself be energetic, this is the best.
