What effect does physical exercise have on health?

The influence of physical exercise on healthy life lies in exercise, which is beneficial to health. With the continuous development and progress of social economy and politics, the improvement of living standards and the change of ideas, people pay more and more attention to the quality of life and self-health awareness, and more and more people attach importance to self-physical exercise. Health is the connotation of modern civilization. Now we are creating a happy life and a bright future with our own actions. Health is the premise, health is the guarantee, and health is an important part. In the modern civilized lifestyle, health has attracted much attention, been promoted to an unprecedented height, and the understanding of health has also undergone great changes. Its concept, essence, content and form have been injected with fresh blood, reflecting its progress with the times and people's understanding of the nature of life. The idea of health first has been transformed into behavior. Physical exercise can make the metabolism of human body vigorous and enhance the functions of various organs and systems, so as to achieve the purpose of enhancing physical fitness and prolonging life. Label: physical exercise; Modern; Health; Influence; Living standard; Ideas; Scientific and modern concept of health The new concept of health put forward by the World Health Organization is: health, not only not being sick, but also including mental health and social communication ability. In other words, health means maintaining a sound state mentally, physically and socially. The organic combination of the above three aspects can constitute the quality of human life. In the three-dimensional cube of human life, the larger the area of physical, psychological and social attributes, the larger the volume of the life cube, the higher its status in nature and society, and the greater its connection with society, indicating that the quality of life of individuals is higher. On the other hand, if the areas of these three attributes are too small, then the smaller the contact surface between individuals and society, the worse the quality of life. The experience of many healthy people tells us that the higher the quality of life, the greater the possibility of health and longevity. On the contrary, if individuals are psychologically depressed and self-enclosed, they will easily get sick and shorten their life span. This also shows that a person can improve his quality of life and ensure his healthy and happy life only by starting from biology, physiology and society. The American University Health Center put forward a definition of health similar to the three-dimensional view of health, that is, an individual can only be called a truly healthy or perfect state if he is healthy in five aspects (also known as the five elements of health). The Influence of Physical Exercise on Health Health is the basic element of human survival and development. Without health, nothing will be achieved. Health belongs to both individuals and society. Physical exercise can make the metabolism of human body vigorous and enhance the functions of various organs and systems, so as to achieve the purpose of enhancing physical fitness and prolonging life. The influence of physical exercise on health The human body is composed of nervous system, circulatory system, respiratory system, exercise system, digestive system, excretory system, reproductive system, endocrine and sensory organs. Physical exercise is accomplished through the coordination of various organ systems of the human body, and at the same time, physical exercise also has a good influence on various organ systems. 3. 1. Physical exercise and digestive system The digestive system consists of digestive tubes and digestive glands. The digestive system can transform food into nutrients needed by the body, send them into lymph and blood stream for the growth and maintenance of life, and excrete the residues in the metabolic process. 3.2. Physical exercise and nervous system The nervous system includes the central nervous system and the peripheral nervous system. The central nervous system is the "headquarters" for commanding the whole body activities. The essence of all human activities is the reflex activity of the nervous system, which is completed through the process of perception, analysis, judgment and reaction. According to Pavlov's words, it is: "On the one hand, the activities of the nervous system unify and cooperate with each other, on the other hand, it is used to make the body have a relationship with the external environment and keep the various systems of the body in balance with the outside world.
