Health-keeping and body-building is a way to exercise health, which is usually promoted by adjusting diet, exercising and maintaining good living habits. Normal fitness work generally has no side effects, but helps to improve the body's immunity and resistance.

However, if the methods of keeping in good health and laying the foundation are incorrect or excessive, some adverse reactions or side effects may occur. These side effects may include eating disorders, weight fluctuation, muscle pain, indigestion, sleep problems and so on. In addition, excessive exercise or unreasonable exercise patterns may cause muscle strain or other sports injuries. Therefore, before starting the basic work of health preservation, it is best to consult a professional health consultant or doctor for guidance to avoid potential side effects.

Generally speaking, the basic work of health preservation itself has no major side effects, but it is necessary to pay attention to the correct method and moderate exercise to maintain the balance and health of the body.
