What reason is human body temperature low?

Hypothermia refers to body temperature lower than the normal value. Taking axillary temperature as an example, hypothermia is lower than 36℃. The main reasons include excessive heat dissipation, decreased heat production, and damage to the body temperature regulation center.

(1) Excessive heat dissipation of the body, such as staying in a cold environment after drinking, so that the body's blood vessels are excessively dilated and heat is lost; Long time exposure to low temperature environment, the body heat too much, too fast.

(2) Decreased thermogenesis. For example, patients with extreme weakness or severe malnutrition have less nutrients to produce heat, resulting in less thermogenesis.

(3) The body temperature regulation center is damaged, such as craniocerebral injury, cerebral hemorrhage and cerebral infarction patients, the central nervous system function is poor, the body can not respond to low body temperature; In patients with spinal cord injury, the body temperature conduction center is damaged and the body is unable to respond to thermogenesis. In major diseases, such as sepsis and massive hemorrhage, the body is in a state of stress, and the thermoregulatory center is unable to respond to hypothermia.

There are many reasons for low body temperature. When there is low body temperature, we should go to the hospital in time and take active treatment under the guidance of the doctor to find out the cause so as not to delay the disease.
