Smoking and drinking cannot prevent any disease, much less the infection of the new coronavirus. Some people realize that they are sober after smoking and excited after drinking, but both are bad stimuli for the body. The body’s immune status can be disrupted after a state of euphoria, which is not conducive to protection against foreign infectious diseases. Excessive smoking and drinking are not recommended during the prevention of infectious diseases, as they may cause the immune system to be in an unstable state, making it susceptible to viral infections. A light diet should be maintained as much as possible to stabilize the body’s condition. If infected with a virus, it is also important to prevent further aggravation by stabilizing the internal environment of the body. Source: Dr. Yurai
