Description

Adaptability of human being to hot environment was discussed from the incidence of heat casualties, the present knowledge of thermoregulation, and from the view point of evolution. The incidence of heat casualties in Japan exceeds 150 per year during hot summer days,and the number of incidence correlates with the number of days with minimum temperature higher than 25 degree C. About 40% of the incidence are found in elderly people over 65, which suggests that elderly people are more susceptible to heat stress with less reserve capacity to tolerate heat. A guide line for the prevention of heat casualty was discussed based on the regulatory mechanism of body temperature, circulation,and body fluid. Human can tolerate the cold more easily than to heat using both behavioral and physiological thermoregulation. On the other hand,it is necessary to elaborate circulatory function and body fluid to tolerate to heat load,which leads to heat casualty more easily. This fact, together with the fact that human being has evolved through ice ages impose the necessity to brake global warming.
