Can exercise boost your immune system?

Usually often cold and fever, you will hear that your body resistance is too weak, usually you can exercise more to improve the body's immunity, enhance physical fitness. We all know that exercise can effectively improve immunity and increase the body's ability to resist viruses, but the specific reasons why exercise can improve immunity is something most people do not know. Here's a look at why exercise can improve immunity.

Why exercise can improve immunity

Immunity is the body's own defense mechanism, which is the body's ability to identify and destroy any foreign invasion of foreign substances, such as bacteria, viruses, etc. The ability to deal with aging, damaged, dead, degenerated own cells as well as identify and deal with mutated cells and virally infected cells in the body.

Ability to increase the number of immune cells

Exercise is able to raise the total number of immune function cells for a short period of time, only to return to normal after a few hours. During the period of elevated white blood cell count, it facilitates the body's ability to destroy invading pathogenic microorganisms. The effect of long-term regular exercise on immune function is mainly manifested in the enhancement of immune function activity, and also a small increase in the number of immune function cells in the quiet state. Therefore, long-term regular exercise in the right amount can strengthen the body's immune function and enhance the ability to fight diseases.

Increases body temperature

When exercising, the body temperature can be increased, and the increase in body temperature is conducive to improving the phagocytic effect of cells on viruses and bacteria, which can help the body to prevent the invasion of original microorganisms, inhibit their reproduction and spread in the body, thus improving the body's resistance and strengthening the body.

Can you improve your immune system by exercising?

It is not true that you can improve your immune system by exercising. Occasional exercise and excessive exercise not only can not play a role in improving the body's immunity, but also may harm the body. Only long-term adherence to the appropriate amount of regular exercise to improve immunity. The scientific exercise practice is to exercise 3-5 times a week, each exercise time control in 40-60 minutes, the intensity of exercise should not be too large. And to continue to exercise for 12 weeks may have the effect of immune system improvement, after 12 weeks still need to continue to adhere to the exercise.

What exercises are more effective in improving immunity

Brisk walking

Brisk walking is a relatively healthy and simple way to exercise, you can continue to walk every day for 30 minutes, can regulate immunity, enhance physical fitness. However, we should also pay attention to control the amount of exercise, you can gradually increase the amount of exercise, exercise time should not exceed 2 hours.

Swimming

Swimming can improve the body's ability to adapt to cold, especially winter swimming, can stimulate and promote blood circulation, improve the body's sensitivity to thermoregulation, and enhance the body's ability to adapt to changes in external hot and cold temperatures. When swimming, the skin will be stimulated by cold water, making the skin's blood vessels contract sharply, and after a strong contraction, there will be a corresponding diastole, so that the blood vessels can be exercised, and thus play a role in improving immunity.

Jogging

Jogging can enhance physical fitness, can strengthen the respiratory system for temperature adaptation, improve the body's resistance, regulate the ratio of white blood cells, macrophages, lymphocytes, etc., and these cells can play a role in phagocytosis of viruses and cancer cells in the body. Jogging should be done at a constant speed, not too fast, to be able to breathe normally.

Yoga

The thymus gland is the center of cellular immunity in the body and is located in the mediastinum of the thorax. Its main function is to regulate the ratio of T-lymphocytes and secrete thymic hormones, so that the body can maintain cellular immune function and kill foreign germs. Many of the asanas and breathing techniques in yoga have the function of stimulating the thymus gland, and by stimulating the secretion of the thymus gland, the body's immune system is enhanced.
