In the fast pace of modern life, most people want to maintain physical health, and they need to adjust and improve themselves, which can be roughly divided into two types: adequate sleep and proper exercise.
But what is good sleep? How can I have a good night's sleep?
You must have heard of the 8-hour sleep theory. Many people believe that you can only get enough sleep if you get 8 hours of sleep each night. In fact, it is not necessary to sleep for 8 hours, but on the basis of a certain period of time, the quality of sleep should be high.
In fact, measuring good sleep status can be roughly divided into three types:
Sleep well: you haven't been disturbed by the outside world, and you haven't woken up halfway through.
Getting enough sleep: According to the recommendation of sleep experts, the sleep time of adults should be controlled between 7 - 9 hours.
Sleep steadily: Keep going to bed and getting up at the same time every day, and try to keep this frequency as often as possible.
As long as you can do the above three points, generally speaking, you have a good sleep.
