Whether or not you can run after catching a cold should be judged according to the severity of the cold. You can run appropriately after catching a mild cold, but running is not recommended for severe colds. 1. Slight cold: If the symptoms of cold are not serious, you can jog appropriately without feeling fatigue and discomfort. 2. Severe cold: If the patient has serious cold symptoms, jogging at this time will increase physical exertion, and even lead to breathing difficulties, resulting in different degrees of hypoxia, which is unfavorable to the recovery of the condition. Patients should pay attention to rest, drink water appropriately, and keep the living environment with fresh air. It should be noted that patients with colds need to exercise according to their own situation, do not exercise strenuously, so as not to cause injury.
