Fitness Tips | What should I pay attention to before and after exercise?
Do not drink a lot of water during and after strenuous exercise
During strenuous exercise, salt in the body is excreted with a large amount of sweat. Excessive drinking will reduce the osmotic pressure of the blood, destroy the balance of water and salt metabolism in the body, affect the normal physiological functions of the human body, and even cause muscle spasms.
During exercise, it is necessary to increase the frequency of heartbeat and breathing to increase blood and oxygen to meet the needs of exercise. Drinking a lot of water will make the stomach swell and fill, hinder the activity of the diaphragm, and affect breathing; the increase in blood circulation increases the burden on the heart, which is not only unfavorable for exercise, but also hurts the heart.

The blood pressure of the infirm will drop after eating, which is called hypotension after meal, and it is easy to fall when going out. Long-term exercise after meals is prone to appendicitis.
