Sleep time does not have to be 8 hours to be healthy. How to define a truly healthy sleep?

For young people nowadays, sleep seems to be a strange circle. They stay up late every night and can't get up in the morning. Recycling in this way, so now young people are overdrawn because of staying up late, and there are many small problems in their bodies. Therefore, some experts suggest that it is best to sleep for 8 hours every day, but is it necessarily healthy to sleep for 8 hours? This is not necessarily false. If you go to bed in the early hours of the night and get up at 8 o'clock the next day, it is also unhealthy, because you are still staying up late. There is also that people of different ages have different sleep times.

Many people around me will set themselves an eight-hour sleep time, thinking that if they don't sleep enough for eight hours, they will not sleep enough, and if they sleep enough for eight hours, they will be healthy.

In fact, everyone's physical condition is different and their age is different. Of course, sleep time can't be unified. It is recommended to sleep for 8 hours, which does not mean that you must sleep enough. It is only a standard of average sleep time, and the scientific method should be to distinguish it by age.

1~3-year-old babies should sleep at least 12 hours every day because their growth and development need enough sleep. Teenagers aged 4~ 12 sleep 10~ 12 hours every day because they are busy with their studies.

/kloc-For adults over 0/8 years old, it is enough to sleep for 7 to 8 hours. For those over 65 years old, it is unnecessary to sleep for 8 hours. The standard of healthy sleep is 6 to 7 hours.

In fact, everyone's sleep is determined according to the nature of work. It is not necessary to sleep for 8 hours, but there must be a regular schedule. Going to bed too late is an overdraft for your health and you will be punished one day. Young people should not think that you can't see anything now, and your physical fitness will decline rapidly when you are old. Sleep is very important to us. Without enough sleep, you can't work hard and attend classes well the next day, so stay up less and sleep more.
