What are the benefits of exercise for your health? Eight benefits of regular exercise to health.

1 Promote the growth and development of teenagers. Regular exercise can promote the growth and development of teenagers, because bones and muscles need a lot of blood during exercise, which contains a lot of oxygen and nutrients, and the metabolism is in a vigorous state; On the other hand, the epiphyseal cartilage is constantly rubbed and squeezed during exercise, and the cells are constantly divided and ossified, which makes the bones thicker and longer, so people who insist on exercise grow taller and their limbs develop more symmetrically than those who don't like exercise.

2. Delaying aging and persisting in exercise can regulate the function of nervous system, accelerate nerve reflex, make the heart beat vigorously, increase blood output and enhance muscle strength; Moreover, exercise needs more oxygen, so regular exercise can exercise the respiratory muscles, delay the aging of the respiratory system, promote the internal metabolism and visceral function of the body, and effectively delay aging.

3 makes people happy. Regular exercise can balance the excitement and inhibition of cerebral cortex, and also increase norepinephrine in blood and brain. Norepinephrine can strengthen the connection between the brain and nerves in various parts of the body and improve the excitability of the nervous system. When norepinephrine in the blood increases, people's mood will become happy.

4. Enhance cold and heat resistance. There is a thermoregulation center in the hypothalamus, which can keep the balance of heat production and heat dissipation in the body according to the external cold and heat changes. Insisting on exercise can improve the sensitivity of the thermoregulation center, regulate the body temperature faster and more accurately, and thus enhance the human body's ability to resist cold and heat. Long-distance running, cold bath, sunbathing, swimming, skating, skiing and other sports are all very helpful for the exercise of cold and heat resistance.
