Causes of hypothermia


One of the most important functions of the brain is to maintain body temperature. To perform this function, it acts in conjunction with other organs, such as the skin and lungs. Instabilities in body temperature affect the functioning of the body. See below what can cause hypothermia, that is, the reduction of body temperature.

  • Circulatory problems

  • Metabolic disorders

  • Shock state

  • Injuries

  • Inadequate diet

  • Alcohol and drugs

  • Use of medicines

  • Other causes

Circulatory problems

Temperature changes caused by circulatory problems are not usually a concern for the patient, as they are usually motivated by the cold and are fought with warm clothing. However, if the symptoms do not go away or even get worse, more serious circulatory problems can be treated.

Metabolic disorders

In this case, thyroid hormones, responsible for the speed of the chemical functions of the organism, are not produced in sufficient quantity, which can cause, in addition to hypothermia, circulatory problems in the extremities of the body and nervous disorders. Another metabolic disorder related to the drop in body temperature is diabetes, which does not allow the body to regulate the amount of sugar in the blood.

Shock state

The state of shock puts the patient’s life at risk. The circulatory system is not able to get enough blood for the vital organs and the individual suffers faintness, nausea, mental confusion, tachycardia (abnormal increase in heart rate) and decrease in blood pressure. One of the symptoms of shock is hypothermia.


Trauma, such as traffic accidents or gunshot woundsare some of the situations in which the patient may enter the aforementioned state of shock and, therefore, suffer a reduction in body temperature.

Inadequate diet

Eating disorders, such as anorexia nervosa and bulimia, can cause hypothermia. The World Health Organization (WHO) mentions that the reduction of body temperature can occur in cases of severe malnutritionbecause, in these cases, the patient has a lower metabolic rate.

Alcohol and drugs

The inappropriate and excessive use of alcohol and illicit drugs it is also one of the factors promoting hypothermia.

Use of medicines

Some drugs can have a side effect of a drop in body temperature. Ingesting, for example, beta blockers it can cause poor blood circulation, causing a decrease in temperature.

Other causes

THE sepsis (generalized infection), infections in newborns Or the advanced age are other causes for the occurrence of hypothermia.
