A hot body but normal temperature may be due to a more vigorous metabolism, strenuous exercise, and hormonal secretion. It is important to note that in order to ensure that the temperature measurement is correct, it is recommended to re-measure the temperature after ten to fifteen minutes. 1. Exuberant metabolism: mainly because of growth and development, cell division increases, which will lead to the body’s metabolism increases, there will be the body hot, but the body temperature is normal performance, this is a normal physiological phenomenon, do not need treatment. 2. Strenuous exercise: If the body is simply hot, but the body temperature is normal, it may also be due to strenuous exercise, such as running, basketball, etc., which will lead to faster blood circulation, increase the body’s metabolic rate, resulting in the body hot. 3. Exuberant hormone secretion: When a woman is in menstruation or pregnancy, due to the body’s hormone secretion, there may also be body heat, but the body temperature is in the normal range of the situation. In addition to the above, there are other conditions that may cause the body to be hot but the body temperature is normal, such as autonomic dysfunction, etc., if we can exclude physiological factors, it is recommended that we go to the hospital for examination, follow the doctor’s instructions in a timely and targeted treatment, do not do it on their own, so as not to delay the course of the disease.
