It is a long-standing misconception that “sweating can cure a cold”, and it is important to know that sweating does not relieve the symptoms of a cold, rather sweating is seen as a prelude to a fever. After a cold, the body’s own defense system works actively to defend itself against invading viruses or bacteria, and at this time some people sweat and even develop a fever and other symptoms. The body’s metabolism speed up, such as then engaged in more intense activities, it will make the body heat increase, metabolism faster, too much energy consumption, while the patient’s resistance is greatly reduced, the cold virus is more likely to take advantage of the situation, if the invasion of the heart muscle, it will increase the burden on the heart and lungs and other organs, easy to cause acute myocarditis, cardiopulmonary insufficiency, and even lead to sudden cardiac death. The exercise sweat to cure the cold is not only unreliable, and even produce more harm, especially for the elderly, children and weak people is harmful. It is also important to note that some acute infectious diseases have initial symptoms similar to a cold and should be seen by a hospital in a timely manner, and if you also use exercise to carry it, you are likely to delay the condition. In addition to following medical advice and taking medication or fluids on time, patients also need to rest and drink more water. In addition to the misconception that “exercise cures colds”, there are also some folk ways of treating colds, such as starvation therapy, sauna fumigation, and drinking to cure colds, which are also wrong. People generally lose their appetite and don’t think about eating after they have a cold, so when they don’t eat, the body’s energy supply will be insufficient, and the various symptoms of the cold will aggravate the energy consumption, and relying on hunger to cure the cold will only aggravate the condition. If you go to sauna with cold, the repeated hot and cold will further weaken the body’s resistance and further aggravate the symptoms; drinking alcohol when you have cold will aggravate the blood vessel expansion and congestion, increase the respiratory secretion and further aggravate the condition, which is not only not beneficial but also harmful.
