The difference between a hot cold and a cold cold mainly lies in the causes and symptoms. If a cold is mainly caused by the invasion of wind-heat evil into the body, it is clinically characterized by yellow urine, coughing up purulent sputum accompanied by high fever, headache, and sore throat discomfort. On the other hand, a cold cold is primarily caused by the invasion of wind-cold evil into the body, and it is clinically characterized by white, thin sputum, and symptoms such as chills, cold limbs, dizziness, and fatigue. Whether it is a hot cold or a cold cold, from the perspective of Western medicine, most are caused by viral infections. Therefore, taking some anti-cold medication or some traditional Chinese medicines can improve symptoms and shorten the duration of the illness.
