The most effective exercise method to resolve phlegm is aerobic outdoor exercise. If illness and physical strength allow, you can increase the amount of exercise in your daily life and do some outdoor aerobic exercises such as jogging and tai chi to increase your body’s immunity. If the disease is more serious and physical strength is poor, encourage indoor activities, or turn over more, pat the back more often, etc., which can also effectively promote the discharge of phlegm. At the same time, a light diet, together with expectorant drugs such as eucalyptus-pinocampus enteric capsule, acetylcysteine, etc., can promote the discharge of phlegm. When patients with unexplained phlegm, they can go to the hospital for further consultation and examination, so as not to delay the condition. The above drugs should be standardized and rationally applied under the guidance of professional physicians and pharmacists.
