First of all, maintaining psychological balance is very beneficial to health. When the mood fluctuates violently, the human body will produce a lot of harmful secretions, which will cause endocrine disorders and be harmful to health, while when the mood is calm, the human endocrine will be normal. Therefore, in life, don't haggle over every ounce, don't get angry easily, keep a generous attitude, be optimistic and easy-going, get what you don't like, lose what you don't like, and be neither arrogant nor impetuous. In this way, we can maintain normal endocrine, thus contributing to health. More importantly, a good mood is the basis of improving human immunity. Under normal circumstances, the human body produces about 3000 cancer cells every day. At the same time, human immune cells will kill them. Studies have shown that human immunity is closely related to emotions. Good emotions such as optimism, self-confidence and peace can stimulate the fighting capacity of immune cells, while bad emotions such as anger, pessimism and depression will reduce the efficacy of immune cells and greatly weaken their ability to kill cancer cells. Therefore, we should restrain our emotions, maintain psychological balance and be calm as water.

Second, keep exercising. Exercise is very helpful to health. Exercise can speed up the blood circulation of the whole body, so that nutrition can fully reach all organs of the body and the tissues of the human body can be fully nourished. At the same time, exercise can improve the metabolism of the human body, so that all kinds of garbage and toxins produced by the human body can be excreted more quickly and thoroughly. Exercise must be persisted. It is useless to fish for three days and dry the net for two days.

Third, prevent in advance. Everything goes through a process, and so does disease. In this process, if we intervene in time, there will be no unpredictable results. Therefore, we should pay special attention to the prevention of diseases at ordinary times, prevent slow progress, and eliminate health hazards in the bud.
