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.

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.

From a health point of view, sleeping for four hours is definitely not good for the body. Because we humans sleep at least six hours a day, of course, the sleep time should be different according to each age group.

For example, the child's sleep time should reach at least about nine hours, if it is an adult, then it should reach at least seven hours, and the elderly generally sleep less time, generally about six hours, we must ensure normal sleep time every day. And to achieve a certain quality of sleep, so that it can be good for our physical health, because we enter the sleep time stage, our internal organs will be improved immunity will be naturally restored, if this time period does not reach the ideal state, then it has a great impact on our body's immunity. Our body's resistance will deteriorate, so try to ensure the quality of sleep as much as possible.

If you don't sleep well, be sure to find the real cause and then address the symptoms**.

Especially for us young people, sleep is very important, because young people work under pressure, life pressure is relatively high, and it is generally easier to stay up late, so people who stay up late must pay attention to sleep as best as possible, and do not stay up late to work and study. Be sure to get a good night's sleep and eat well.

People only sleep 4 hours a day, whether it has an impact on physical health.

Sleep is our normal physiological activity, our body gets enough rest when sleeping, each organ runs its own role, so that we can work energetically on the second day, too little sleep time every day will cause a great burden on the body, affecting the normal work of various organs in the body.

Normal people should sleep a stable time of about 7 hours a day, if they have a good sleep quality, with an adaptable schedule, you can adjust it to about 6 hours a day, but 4 hours is really too little, our body can not get effective rest, we sleep every day to ensure that the sleep time is two hours to three hours to make our work, study and life not affected, 4 hours to the eye movement cycle to the light sleep time deep, the sleep time is very short, probably about two sleep cycles, In this way, the body does not get effective rest, which will lead to a decrease in immunity, resulting in a worse state and a worse working state.

When our brain is in the state, it will think with high efficiency, half an hour may be able to complete an hour or two hours of work, but if we use time for a long time to boil, we will find that our brain is in chaos, sometimes we feel that the limbs are not under our control, and the body often appears particularly weak, or even to sweat, which means that our body has a problem. We need to take proper rest, and if the condition is more serious, we should also consult a doctor to recuperate our body.

No matter how busy young people are at work and studying, they still have to ensure normal rest, at least not less than 6 hours, because the sleep time is too short, our body can not get effective rest, our work, study and life will be inefficient, feel that our brain is chaotic, and we can't concentrate on anything.
