What is the definition of health? What are the five elements?

Health means that a person is in a good physical, mental and social state. The traditional concept of health is "disease-free health", while the modern concept of health is overall health. The World Health Organization puts forward that "health is not only physical health without disease, but also mental health, good social adaptation and morality". Therefore, the health contents of modern people include: physical health, mental health, mental health, social health, intellectual health and moral health. Health is the basis of quality of life; Health is an important aspect of human self-awakening; Health is the best state of life, with rich and profound connotations.

As for the five elements, I don't understand.
