In clinical practice, the body temperature of the human body is constant and should be between 36.3 and 37.2 degrees, whether it is in the spring, summer, autumn or winter. If the body temperature exceeds 37.2 degrees, hypothermia may exist and should be examined according to the patient’s symptoms, such as inflammatory infections that may lead to hypothermia, and viral infections that may also lead to hypothermia. Therefore, through the above analysis, the body temperature of a person in winter is within the normal range of 36 degrees, but winter is the season of influenza outbreak, once the body temperature is greater than 37.2 degrees, you should go to the hospital for detailed examination to find the foci of the disease, and then the symptomatic treatment, in order to ensure the health of the human body.
