Causes of low body temperature

Probably, each of us knows that the normal body temperature of a healthy person is 36.6 degrees. If it increases, this indicates a pathological condition of the body or the development of a particular disease in it.

What to do when the temperature rises, we all know - to try to understand its main causes, and then bring it down to normal readings with antipyretic drugs or traditional methods.

But there are situations when a person's body temperature is lowered. What to do in this case and what could be the causes of this phenomenon? Let's talk about this in this article.

Diseases that can provoke hypothermia

Low body temperature in humans (35.5 and below) can provoke certain diseases:

  • various options for internal chronic diseases at the time of their exacerbation.
In addition to the above illnesses, the temperature decreases with:

  • state of shock;
  • hypothermia;
  • chronic sleep deprivation;
  • fasting and tough diets;
  • depletion of the internal forces of the body;
  • a large amount of alcohol drunk;

  8. The causes of this phenomenon may be chronic diseases, namely the moment when they progress. These include vegetative-vascular dystonia.
  9. Common cold (ARI or ARVI), flu. Oddly enough, these diseases can provoke both an increase and a decrease in temperature.
  10. A brain tumor that occurs in the hypothalamus, which is responsible for the exchange of heat in the body, also causes chills and, as a result, a decrease in temperature.
