Most patients with upper respiratory tract infections can properly sweat. Upper respiratory tract infections are caused by a decrease in the body’s immunity, mostly due to cold, which causes viruses, bacteria and other pathogens to invade and infect the body, and at this time proper sweating can remove the cold in the body and can promote blood circulation in the body. A proper sweat can also expel some pathogens from the body, such as viruses and bacteria, and the body’s immune system is active in the process of sweating, which can promote blood metabolism and improve the body’s immunity. However, in the process of steaming, you must pay attention to wearing warm clothes as soon as possible after steaming to avoid getting cold again.
