What it is necessary to cure, not to freeze?

The human body constantly carries out heat exchange with the surrounding air. At the same time, there is a balance that allows maintaining the temperature inside the body at a level of 36.5 degrees. But some diseases and processes disrupt the process of thermoregulation, leading to a deterioration in well-being.

How does heat exchange occur in the human body?

The microclimate of the body depends on three main parameters:

Thermoregulation occurs simultaneously in all three ways.

Why is the heat exchange disturbed?

The change in the temperature balance is manifested by the following diseases:

All these diseases are caused by a violation of the central nervous system and the hypothalamus. This part of the brain contains special neurons that connect the spinal cord and the brain.

Let's consider each disease in more detail.

Hypothermia

This ailment is characterized by a body temperature with a lower value - less than 35 degrees. Most often, hypothermia is accompanied by autonomic dysfunction.

Among the symptoms of the disorder in question, general weakness of the body, low blood pressure, worsening of working capacity, increased sweating should be noted.

Hypothermia usually occurs against a background of such diseases as hypothyroidism , exhaustion, hypopituitarism, parkinsonism, orthostatic hypotension. In addition, it causes intoxication with alcoholic beverages, a prolonged stay in a cold room or water, as well as taking certain medications (barbiturates, butyrophenones, benzodiazepines).

Hyperthermia

This syndrome is of three types:

In the first case, hyperthermia is also called a crisis. It is accompanied by a sharp increase in temperature to 39-41 degrees. In this case, there is a strong reddening of the face, headache, muscle tension. Paroxysmal hyperthermia passes quickly, after which the patient feels weakness, fatigue, drowsiness.

The permanent type of the disease is characterized by long lasting (up to several years) body temperature at a level of 37-38 degrees, and this is not associated with infectious diseases. In people suffering from this disease, heat exchange is sometimes normalized, mainly in summer and in spring. Most patients normally suffer permanent hyperthermia, in rare cases, complaints of headache, weakness occur.

Mixed or permanent-paroxysmal type of disease combines the symptoms of the two previous types: a constant value of body temperature from 37 to 38 degrees with a sudden increase to 39-41 degrees.

Causes of hyperthermia:

Syndrome of "fever"

This disorder manifests itself in a constant sensation of cold to the patients, "goosebumps" along the body, low pressure, weak pulse, increased sweating, respiratory system disorders.

The main cause of the syndrome of "chills" are mental disorders in combination with phobias and the parenchymal-hypochondriacal condition.

Chronic hyperkinesis

The disease under consideration has such symptoms as sudden feeling of chills, trembling inside the body, muscle tension. The reasons for this are:
