Hypothermia of the Body

Hypothermia of the body. Hypothermia or hypothermia is a serious medical condition characterized by a decrease in body temperature below 35 degrees Celsius. For the human body, a drop in body temperature to 25 °C is critical, although the consequences will already occur at a temperature of 26 °C. At a level of 20 °C and below, the activity of the nervous system and brain is disrupted. The temperature of the cerebral cortex is critical; the temperature of the internal organs decreases to 23 °C or lower in trained people. Since even heat loss through the skin from the surface of the entire body is about 40-60 W, and in order for the body to receive heat from the external environment it is necessary to absorb heat (at an ambient temperature of 30ºC a person must cool down by at least 0.2ºC per minute), hypothermia is critical occurs when heat loss per unit surface area is more than 50-65 W/m². In everyday life, the most common cause of hypothermia is being in the cold without appropriate clothing or without shelter, getting wet clothes (if the “warm-up clothing” principle is used) or another layer of clothing on the side of the body and with the obligatory covering of the head, as well as fasting and slowing down movements.

Hypothermia can be caused by the following factors: * Excessive physical activity at low ambient temperatures;

* Low calorie diet;

* Excessive fluid loss in conditions of low temperatures and insolation;
