When treating a cold, many people will take some native methods, such as covering sweat and exercise. Some of these methods are introduced by others, and some are created by themselves. Medical experts point out that these methods, if used improperly, not only to the body is not beneficial, but also aggravate the disease. First, many people think that the cold and flu cover sweat will be good. When the patient is afraid of cold and not sweating, let the patient drink hot ginger soup, cover the body with a quilt, until a big sweat. This does not necessarily reduce the disease, especially when the patient sweats too much, it is very easy to dehydration, will aggravate the disease or cause other complications due to electrolyte imbalance. Second, many people like to use “exercise therapy” to treat the cold. Especially some young people, once suffering from a cold, they will deliberately carry out some physical work, or go to the sports field to run a few laps, play a basketball, etc. This practice is often counterproductive. This practice is often counterproductive, simply increase the amount of exercise will increase physical exertion, so that the body’s ability to fight disease is reduced, may lead to aggravation. Third, a cold to take medicine. Many people are desperate to take medicine when they have a cold. In fact, the body itself has the ability to naturally cure a cold. Sneezing, coughing, runny nose and high fever can drive the germs out of the body and weaken the destructive power of the germs. Taking medication for a long time will make people resistant to it and reduce its effectiveness. Fourth, a variety of drugs to eat together. Many people suffering from the cold want to make the condition improve as soon as possible, often taking a variety of drugs at the same time for treatment, thinking that the more drugs the better the efficacy will be. In fact, this is a wrong approach, because some drugs taken at the same time will offset each other’s potency, and serious and even toxic side effects.
