Clinical manifestations of cold, headache and dizziness are usually due to fever, and body temperature can be monitored. If the body temperature exceeds 38.5℃, oral antipyretic medication is recommended, e.g., Merrill Lynch, Roxarsone, etc. If the body temperature is lower than 38.5℃, physical cooling can be given, such as warm water bath, which can wipe the forehead, armpits, palms and feet. At the same time, drink more water, eat more fresh vegetables and fruits, replenish minerals and vitamins, and improve the patient’s body immunity. If the patient has a lot of sweating after oral antipyretics, pay attention to fluid replacement, and pay attention to replenish potassium ions, because a lot of sweating and fever, can induce hypokalemia, can eat potassium-rich foods or fruits, such as bananas, oranges, tangerines and so on.
