The main way for human body to absorb nutrients is to absorb them from food, which needs to be decomposed and absorbed in the stomach to become nutrients. Fasting exercise, at this time will increase the consumption of energy and substances, will cause greater harm to the human body. Therefore, exercise is best done half an hour after meals or with sufficient energy.
Exercise is not a matter of once and for all, and the interval between exercises should not be too long. Exercise can enhance physical fitness, strengthen muscles and bones, but it is not advisable to increase exercise intensity quickly in a short time. As we all know, exercise itself is consumptive. If we constantly increase the intensity of exercise, beyond the body's endurance and adaptability,it will not play a role in strengthening the body, but cause harm to the body. Therefore, exercise should be gradual and persistent, not blindly exercise,don`t rush it.
During and after exercise, the body urgently needs to release heat in the body.The capillaries of the skin expand, and the pores of the whole body will open. If you take a cold bath immediately, the skin will be subjected to super-cold stimulation, capillaries suddenly contracted, which is not conducive to heat emission. Excessive stimulation from heat to cold can also cause the dilated pore to close urgently, and the immunity of the human body decreases accordingly. At this time, bacteria are most likely to invade. And the shower does not help the muscles relax, but will make the muscles more tense. The correct way is to take a bath with warm water after the sweat has dried up. The temperature of the water should be higher than the body temperature of 1-2 degrees Celsius, so that the muscles can be fully relaxed.
After exercising, water should be supplemented, but excessive water should be avoided. After exercise, the organs and systems of the human body also need rest. At this time, a large amount of water will add a heavy burden to the digestive, blood circulation and other systems, especially to the heart. The best way to replenish water after exercise is to use a small amount of water several times, so as to maintain the balance of water in the body without increasing the burden of drinking too much water. At the same time, after vigorous exercise, a large amount of blood flows to the moving muscles and body surface, while the digestive organs are in a relatively anemic state. Drinking frozen drinks at this time will bring strong stimulation to the stomach and easily induce acute gastritis and other diseases.
