When a fever occurs, the head is hot and the hands and feet are cold, often because of the constriction of the peripheral blood vessels caused by the fever. Cold hands and feet must use warm water to soak the hands and feet, so that the hands and feet warm up, the circulation around them can be good, and the blood circulation in the hands and feet will be relatively good, the blood vessels will stretch and take away the excess heat from the body. In addition, if the head is relatively hot, you can also put a fever patch on the forehead, use a cold towel on the forehead to cool down or put a hot water bag filled with cool water on the forehead to cool down, the effect is good. If the body temperature is above 38.5℃ and you need to take antipyretics to improve head fever and cold hands and feet, you can take ibuprofen suspension or acetaminophen granules to reduce fever. After an interval of 4-6 hours, you can repeat the medication once, not more than four times a day can be used.
