A prolonged period of body temperature around 35°C is an abnormality. Under normal circumstances, the body temperature will be in a constant state, can fluctuate within a certain range, according to the different measurement methods are divided into axillary temperature, oral temperature and anal temperature, etc., for example, the armpit temperature of a normal person is 36 ℃ ~ 37 ℃, the anal temperature is 36.5 ℃ ~ 37.5 ℃, the oral temperature is 36.2 ℃ ~ 37.2 ℃. Body temperatures above or below the normal range are abnormal. Normal and constant body temperature is an important condition for maintaining the body’s metabolism as well as normal life activities. When the body temperature is abnormal, it will affect the normal metabolism and make the human body experience various discomforts. For a long time in the body temperature of about 35 ℃, it is likely to be related to the extremely weak people, patients with hypothyroidism, or may be in a state of shock. People with extreme weakness may experience hypothermia due to low metabolism of the body and slow blood flow. The slowing down of the basal metabolism caused by hypothyroidism can also cause hypothermia. Hypothermia may also occur in patients with shock due to inadequate perfusion of blood volume. In order to clarify the cause of the disease, it is necessary to go to the hospital in time, ask a professional doctor for an interview, and improve some relevant tests.
