The World Health Organization defines health as: "Health is a state of physical, mental and social adaptation, not the absence of disease and weakness." From the definition of health by the World Health Organization, it is obviously different from our traditional understanding: it contains three basic elements: (1) physical health; (2) Mental health; (3) Social adaptability. Social adaptability is an internationally recognized primary standard of mental health. Overall health includes physical health and mental health, which are closely related, indispensable and inseparable. This is the essence of the concept of health.
Therefore, on the one hand, teenagers should pay attention to reasonable diet and physical exercise in their daily life, on the other hand, they should cultivate their own sentiments, broaden their minds and avoid being in a tense emotional state for a long time. If you feel that your mood continues to be unhappy, you should make psychological self-adjustment in time, and go to a psychological clinic or psychological counseling center for help when necessary to ensure your overall psychological and physical health.
