Body temperature of 35 degrees has a certain risk, hypothermia is common in hypothyroidism, traumatic brain injury after the central regulation of body temperature disorders, as well as more serious condition of some shock patients, and children’s scleroderma, etc., the latter two cases are more dangerous. Under normal circumstances, the body temperature is 36 degrees ~ 37.2 degrees, if the body temperature is lower than 36 degrees for hypothermia. 1. When the patient’s hypothermia is due to hemorrhagic or infectious causes of shock, the lack of blood volume leads to hypothermia, such a patient is at some risk. 2. If it is a child hypothermia may be children neonatal sclerosis, easy to cause heart failure, pulmonary dysfunction, serious life-threatening.
