hyperthermia promotes everything that somehow violates the process of sweating or impedes the evaporation of sweat: a combination of high temperatures and humidity, wearing synthetic clothing, the use of rubber or leather overalls during heavy physical work, long hikes in hot weather, fatigue, abundant fatty foods, lack of fluid intake.

Most often heat stroke occurs when significant dehydration during intense exercise provided an increased ambient temperature.But this does not mean that the air temperature at a comfortable develop

There is thickening of the blood and an increase in its viscosity.As a result, blood flow leads to difficulty tissue hypoxia.Violated respiratory function, there is a malfunction of the kidneys.There is a metabolic disorder in the body.He suffers from the central nervous system - is developing tissue edema and brain membranes are marked multiple hemorrhages.For this state is characterized by congestion of internal organs and the presence of punctate hemorrhages in the stomach and intestine, and bleeding under the epicardium, endocardium and pleura.
