Acclimatization to heat and cold

Methods to Estimate Acclimatization to Urban Heat Island Effects on Heat- and Cold-Related Mortality

BACKGROUND Investigators have examined whether heat mortality risk is increased in neighborhoods subject to the urban heat island (UHI) effect but have not identified degrees of difference in susceptibility to heat and cold between cool and hot areas, which we call acclimatization to the UHI. OBJECTIVES We developed methods to examine and quantify the degree of acclimatization to heat- and co...

Cold Acclimatization in Eskimo

0 N EXPOSURE to cold the body has a complicated physiological problem to solve. There is a limit to the heat it can produce to provide for an increased heat loss and during exposure of much severity a heat deficit is incurred. While peripheral tissues are cooling, the central body temperature must be kept within a very narrow range if the function of vital organs is to be maintained. If the acc...

The circulation in cold acclimatization.

The hand and forearm blood flow of the Eskimo has been found to be greater than that of a control group of white persons in a temperate climate both at rest at an ambient temperature of 20 C. and during acute cold exposure. Under cold stress, rectal temperature was better maintained in the Eskimos, though certain deep muscle temperatures fell more than they did in the white men because of the g...
