The symptoms of headache and nausea when the patient blows on the air conditioner are related to the spasm and constriction of blood vessels in the head caused by the air conditioner, and also related to the coldness of the air conditioner that causes the person’s gastrointestinal tract to get cold. Therefore, in this case, the patient should immediately get out of the air conditioning environment to avoid the body to continue to be cold. Patients can stay in a warm place for a while, so that the body in a warm state can be improved. If the patient’s symptom relief is not obvious, it is recommended to give the patient ginger slices or boil water with ginger, which can play the role of warming the stomach and removing cold, and can improve the patient’s headache and nausea. If symptom relief is not obvious, it is recommended to give the patient oral duliang drops and Chuanxiong tea-tone powder to disperse wind and cold and relieve the symptoms of headache and nausea.
