If you get enough sleep, your skin will get better if you sleep soundly. If you often stay up late, your sleep will be irregular, and your skin will look dull if you don't get enough sleep. Adequate sleep is very important for the skin. People's mental state, health state and environmental factors will all have certain effects on the skin. 10 afternoon to 2 am is the most vigorous time for skin cell metabolism. Therefore, you usually need to develop good sleep habits and don't stay up late. Don't face computers and mobile phones for a long time.

Going to bed early and getting up early is a healthy lifestyle often advocated by health care experts, but surprisingly, if going to bed early and getting up early exceeds a certain level, it may be a disease. There is a strange family in Utah, USA. Five members in three generations of this family have very abnormal sleep patterns. They always climb into bed at five or six in the evening and start to sleep, and then wake up in the early morning. This has been the case for decades.

After several days of continuous observation, the doctor confirmed that it was a rare disease and named it "Early to bed and early to rise syndrome". After being reported by the local media, some people called it "early bird syndrome".
