1. First of all: Generally, 0: 00 to 3: 00 is the time for deep sleep, and it takes about 1 hour-1.5 hours to enter deep sleep. So the latest time to fall asleep at night is 10: 30- 1 1. Nowadays, many people have this phenomenon because of high work pressure. Adequate sleep is very important, but not everyone can achieve good quality. This is related to factors such as work and living environment, but we can guarantee a normal daily life. I can sleep through yoga breaks.
2. Secondly, it is suggested that primary and secondary school students (6 ~ 18 years old) generally sleep no more than 8 hours a day and night; 19 ~ 55 years old, the sleep time should generally not exceed 7 hours; It usually takes about 6 hours for people over 60. Of course, the above sleep time is only a reference time. How much everyone sleeps should also be considered according to their own physique, nutritional status, living conditions, environment, mental and physical strength, labor intensity and other comprehensive factors.
3. Finally: Deep sleep is a part of sleep, accounting for only 25% of the whole sleep time. Deep sleep is also called "golden sleep". People's sleep at night is generally divided into five to six cycles, and each sleep cycle is about 60 minutes to 90 minutes. The length of sleep is also related to the length of life. A large-scale epidemiological study has confirmed that both too short and too long sleep time seem to affect people's life span.
