Studies have proved that the best time to sleep at night is before 10, and sleeping after 10 is considered as staying up late, because after 10, various organs of the body begin to enter a state of dormancy and detoxification. If you don't sleep at this time, it will increase the operating burden of various organs. Therefore, it is suggested that you must sleep before ten o'clock at night, which is a way to be responsible for your health.
