Don't stay up late, because of individual differences, there is no standard definition of how late to sleep, and the specific time to fall asleep can't be used as a standard for staying up late.

Staying up late not only refers to falling asleep too late, but also refers to irregular sleep in a cycle, such as sleep time in the morning and evening (one day 10, 2 o'clock a day) and sleep cycle disorder (one day 12 hours, 5 hours a day). No matter when you sleep, as long as you keep a fixed sleep cycle and a relatively stable sleep duration, it is not called staying up late.

For example, if you are used to 12 going to sleep and getting up at 7 am, it is not staying up late. But if you are used to falling asleep every night 10, and occasionally fall asleep after one night 12, then you will stay up late.

Lying in bed for a long time, activities are reduced, and if you don't get up on time to eat in the morning, gastric juice will digest our gastric mucosa and cause certain harm to our stomach. Long sleep can also lead to slow metabolism, insufficient blood supply, and often feel weak and tired.

In addition, people who go to bed early and get up late generally have poor sleep quality, sleep for too long, find it difficult to fall asleep at night, sleep lightly all night, sleep deeply for a short time, and get insufficient relaxation and rest. The mental state of the next day could not be restored.

A good sleep should establish a regular work and rest system, and it is best to go to bed early and get up early. If you can't do it, try to be regular and try to be close to 6~8 hours.
