How can the human body be considered healthy?

It is generally believed that the absence of disease or disability means health; Medical staff once thought that "a strong body and perfect functions, and can play its role" is health. With the development of medical science, people realize that health is a complex comprehensive state, so the World Health Organization puts forward that health is not only the absence of disease or physical exhaustion, but also a sound physical and mental state and social adaptability. Its connotation mainly includes:

(1) People are in a sound and peaceful state, feel comfortable and can lead a normal life;

(2) Feeling good about yourself is the basic element of health; Weakness, discomfort and illness make people feel bad;

(3) Optimistic, positive-minded, able to adapt to environmental changes, adjust their own state, and actively participate in labor and social undertakings;

(four) to engage in all kinds of work and labor efficiently and happily, to be responsible for the family and society, and to make due contributions;

(5) Good moral cultivation does not harm the interests of others and the public.

Health is a complicated life process, which needs to be fought for and maintained.
