The human body is provided with various mechanisms for maintaining almost perfect thermal balance, even in extreme environments. Yet, the organism cannot always successfully protect itself against thermal aggression, and that sometimes results in serious illnesses when internal heat production and/or external heat uptake surpass heat loss. However, temperature is not the alone factor. Several other climatic parameters (namely humidity and wind) often play a decisive part, as well as the special vulnerability of the subjects exposed to heat.
