The difference between high fever and low fever is based on the specific body temperature value, the normal underarm body temperature of human body is 36-37℃. If the body temperature is between 37.0-38.5℃, it means low fever, and when the body temperature exceeds 38.5℃, it means high fever, which is accompanied by headache, dizziness, generalized weakness and other symptoms, while the body does not have obvious self-conscious symptoms or the symptoms are relatively mild when the body has a low fever. The human body itself has a thermoregulatory center, so that the body temperature is maintained in the normal range, in the absence of serious infectious diseases, if the body temperature is in a low fever state, by drinking more water or sweating, temporarily without medication, the body temperature can be restored to normal. If the fever is high, you need to take medication to reduce high fever, commonly used drugs are ibuprofen capsules or acetaminophen tablets, when the body temperature is elevated, you need to identify the cause of the disease, and timely symptomatic treatment.
