When I was 27 years old, crow's feet appeared, which was directly related to staying up late and fatigue. Chinese medicine believes that staying up late is a "dark consumption of kidney essence". People who often stay up late will gradually weaken their immunity, often get sick, and their kidney qi will gradually weaken. This must be noted.

You are 27 years old. At this age, staying up for a few nights is not a problem. You will recover soon after a rest. But often, the damage is very serious. It is suggested that if there is nothing special, it is best not to stay up late. In addition, eating more black things can tonify kidney essence and improve staying up late.
