In the past, the definition of physical health was "being able to engage in daily activities with energy and agility, not feeling too tired, optimistic, energetic and capable of stress". However, at present, what is good health? Some people think that the concepts of health and healthy behavior should be distinguished. Health means that the circulation, respiratory system, various organs of the body, joint activities and muscle strength have reached the normal minimum level, which will help reduce the risk of degenerative diseases.
Healthy behavior needs a certain level of health, and it is related to agility, speed, muscle endurance and contractility, which can make the body better engage in physiological activities in occupation and entertainment. The World Health Organization (WHO) defines physical health as: "Health not only means that a person has no symptoms or diseases, but also means that he has good physical, psychological and social adaptability".
Extended data
Health not only refers to whether a person is sick or weak, but also refers to a person's physical, psychological and social integrity, which is a relatively complete scientific concept of health in modern times.
For any organism, health is a dynamic balance. This is a state of balance: energy and matter are evenly input and output (even allowed to grow). Health also means the expectation of continuing to live. For animals with feelings, such as human beings, it is the spirit of all things, born with two better lifestyles, spiritual and material, so the concept of health cognition and requirements will be broader.
