Almost all human organs grow fastest from night to early morning, because at this time, the human body consumes the slowest, and the body has enough time for positive metabolism and renewal of dead cells. This also forms the body's biological clock. People who often stay up late may not see anything wrong, but the result of going against the weather is that they can't carry out normal renewal activities under appropriate conditions. Over time, the overall function of the body will slowly decline. Once symptoms appear, that is, quantitative change begins to turn into qualitative change, which cannot be remedied by drugs. Therefore, ensuring a normal sleep start time is the correct way to keep fit. Wisdom teeth stop hurting when they grow up.
