First, good cardiopulmonary function.
The heart and lungs are the main internal organs of the human body. Only a healthy heart can develop its myocardium and its heart capacity will be large. Only by jumping once can you discharge more blood than ordinary people. The body needs a certain amount of blood in a certain period of time. If the heart beats more blood at a time, the number of heartbeats will also decrease.
Second, good growth and development.
A healthy person is in good health and usually develops well. From the appearance, you can directly see that you are tall and strong, and from the external image, you can directly see a person's health.
Third, good physical fitness.
The human body needs to exercise every day, and these are the effects achieved by muscles under the control of the nervous system. Muscle condition, such as strength, speed and endurance, will directly reflect the functionality of the nervous system and is also a sign of health. Under normal circumstances, healthy people's muscles are relatively large, and the corresponding overall strength is also relatively large.
Fourth, adaptability and disease resistance are better.
The outside world is changing all the time, and the human body needs to take advantage of the changes in the outside world in time. When the temperature rises, the body will dissipate heat through the expansion of capillaries, and when the temperature drops, the body will also generate heat through muscles, and at the same time, the body will respond accordingly to reduce heat dissipation, thus maintaining the balance of the body, as well as the invasion of bacteria.
