For thousands of years, people have adapted to sleeping at night and working during the day, both mentally and physically. This is a subconscious biological activity cycle - the biological clock - formed in the process of human evolution.

The adjustment cycle of the body's biological clock is 3-5 days. People who often work two shifts have their bodies constantly adjusting. They may not eat well, sleep well, feel weak, and feel listless. Over time, this will lead to a decline in the body's immune function. Aging accelerates and even affects various normal functions of the human body.

A large number of factories arrange double-shift working methods for efficiency, which has caused great harm to the workers' bodies and minds!
