Exercise and immunity

Is it against another cough or a cold? Are you always tired? Walking every day or doing simple exercises several times a week may make you feel better.

Exercise helps reduce the possibility of heart disease. It also keeps bones healthy and strong

I do not know if exercise will increase immunity against certain diseases or how it will increase. There are several theories. However, these theories have not been confirmed. Some of these theories are:

Physical activity helps to wash bacteria from the lungs and respiratory tract. This may reduce the possibility of seizing a cold, flu or other illness

Exercise causes changes in antibodies and white blood cells (WBC). White blood cells are immune system cells whose body resists disease. These antibodies and leukocytes spread more quickly, so they can be found faster than before. But no one knows if these changes will help prevent infection.

A brief rise in body temperature during exercise and after exercise prevents bacterial growth. This temperature rise may help the body better resist infection. (This is similar to the situation at fever.)

Exercise slows release of stress hormone. Some stress increases the likelihood of getting sick. Lower stress hormones can prevent disease

Exercise is good for you, please do not exercise much. People who are already exercising should not exercise simply to increase immunity. Long-term long-term exercise (such as marathon running and intense fitness training) may actually result in injury.

Those who follow the medium energy lifestyle are shown by research to get the most benefit from the beginning (and sticking to it) of the exercise program. Moderate plans include:

Exercise makes you healthier and healthier. It can help you feel better about yourself. So, go ahead and take aerobics class or go out for a walk. You will be better and healthier

There is no strong evidence that immune supplements and exercise can reduce the likelihood of disease or infection

Moderate to high intensity exercise stimulates the immune system by improving blood circulation, thereby enhancing the circulation of various immune system substances in the body. This positive effect is felt several days after exercise. RESULTS: Due to this immune enhancement, it is relatively rare to see people with physical activity with upper respiratory tract infections (URTI) such as sore throat, cold or sinus infections. On the contrary, engaging in intense activities seems to temporarily change our immune defense. Everyone who performs intense training similar to training required for triathlons and marathons increases the risk of releasing stress hormone (cortisol, endorphin, etc.) into the body. Due to this repeated stress, scientists came to call it "open window". Defense system is one to three days sensitive to URTI.

The immune system plays an important role in helping the body recover after thorough training, but the immune system itself is overwhelmed by endurance and its consequences. Three days after this experience, immune cell function is still inhibited, so the susceptibility of the athlete to viral infection and bacterial infection is greatly increased. There are several reasons for this effect, and it seems that it is not fully understood. Part of the problem is that the main fuel of immune cells like amino acid glutamine will be depleted by exhaustive exercise. The immune system is also likely to down regulate its inflammatory response to tissue injury in order to avoid uncontrolled systemic inflammation which would otherwise be caused by high muscle injury. However, this stubborn sluggishness may weaken the ability of the immune system to fight against foreign invaders.

The mechanism proposed to explain the increased "disease" symptoms is related to the immune system's response to tissue damage associated with excessive exercise and lack of recovery. When the tissue is damaged, immunomodulatory molecules called cytokines are released. In some individuals, these cytokines stimulate the branches of the immune system associated with airway hyperresponsiveness and inflammation. This mechanism explains how individuals show symptoms of "cold" without infection.
