With the coming of winter, there are more people suffering from colds, because colds are a common disease that can be easily cured. Moreover, for mild colds, doctors suggest that you don't need medication, rely on the body's resistance, appropriately increase the amount of water, eat light food, and pay attention to rest and sleep, so you can heal yourself. Therefore, some people think that a cold is just a minor illness and there is no need to worry. As long as you don't have a fever, you can take part in exercise during a cold. Some people even want to sweat a lot during exercise to lower their body temperature and relieve cold symptoms. So, can exercise treat a cold? First of all, exercise during a cold is not conducive to the recovery of the body. On the surface, increasing sweating through exercise seems to accelerate the elimination of viruses in the body. It is true that some people feel a lot less cold symptoms after sweating, but this is only a temporary illusion. A cold is caused by viruses or bacteria that invade the body. At this time, the body's defense system will strengthen its work, such as rising body temperature and leukocytosis. And exercise will increase the body's heat production, leading to immune regulation disorder. Cold patients have low physical function, even if the exercise intensity is small, they will bear greater physiological load. After exercise, there will often be immunosuppression, and then the body's resistance will drop, which will make the cold worsen rapidly or not heal for a long time. In addition, exercise increases the oxygen consumption and the burden on the heart and lung system, especially for cold patients with fever. The virus invades the myocardium, which will lead to acute myocarditis and cardiopulmonary insufficiency, leading to more serious consequences.

In short, it is best not to exercise during a cold. We should give priority to rest and recovery to avoid fatigue. Adequate rest and reasonable nutrition are the best ways to treat colds, but exercise and sweating are harmful to colds. Even if the cold is cured, exercise should be done step by step, so that physical strength can gradually recover. Otherwise, after intermittent exercise, the body may feel uncomfortable due to exercise, and sometimes the immunity will drop when the physical strength is insufficient, leading to repeated colds. As a sign of body resistance, good immune function can help people resist the invasion of germs. Moderate exercise can improve immune function and reduce the risk of infection. Therefore, exercise helps to prevent colds. A study shows that sports lovers catch fewer colds than those who never take part in sports. This shows that reasonable exercise can make beneficial changes in the immune system, which is conducive to people's resistance to diseases. In winter, if physical conditions permit, we should still insist on outdoor sports. We can choose comfortable and warm clothes, shoes and socks, and do proper physical exercise in sunny periods and leeward places to increase our adaptability. Those who are old and weak or should not go out for exercise should insist on doing physical exercise indoors, pay attention to air circulation and maintain a certain humidity in their living environment. Pay attention to replenish enough water before and after exercise.
