Moderate work and rest refers to the reasonable arrangement of various activities, including physical activity, mental activity and sexual activity. Any activity should adhere to the principle of moderation, neither too much nor too little.

Human physical activity includes two aspects: labor and sports. Persisting in labor and exercise can promote qi circulation, blood circulation and joints, thus enhancing the body's disease resistance. However, if you are overworked and exceed your endurance, it will also cause damage to your body and affect your health. Excessive comfort can easily lead to stagnation of qi and blood, thus inducing various diseases.

Emotional activities within a certain limit, including mental work and entertainment, are normal and necessary, but if they exceed the limit, emotional activities will be too intense or last too long, which will also lead to various diseases.

A person's sexual life must be moderate and moderate, which plays a key role in a person's life and death. Excessive indulgence will exhaust the essence in the kidney, so "cherishing essence" and "abstinence" are important principles of TCM health preservation.
