Sleep as long as possible?

The answer is no, Chinese medicine believes that lying down for a long time hurts the spirit, that is to say, too much sleep dissipates the spirit and makes the yang and spirit slack. Modern research has proved that excessive sleep and bed rest can cause nerve inhibition of cerebral cortex cells, leading to fine brain hypoxia. Therefore, sleeping more is not good for your health.

So, how long is it appropriate to sleep? Sleep time varies from person to person, there is no absolute value. It is generally believed that 8 hours' sleep is normal. In the questionnaire survey of 654.38+00000 people, it is found that 80% of adults sleep within 7-9 hours every day. Another survey of 800 people found that the average sleep time was 8.5 hours. In addition, short sleepers who sleep for 4~5 hours and long sleepers who sleep10 ~1hour only account for 1%~2%, while ultra-short sleepers who sleep less than 4 hours and ultra-long sleepers who sleep more than 1 1 hour do not.

In short, the sleep time varies from person to person, and the average person can generally be in the range of 6 to 9 hours.
