Acclimatization to Cold in Humans

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...

Effects of cold acclimatization on liver di- and triphosphopyridine nucleotide.

The levels of oxidized and reduced diand triphosphopyridine nucleotide were measured in liver tissue from rats that had been exposed to cold (40 ± 1° C) for one month. These animals exhibited about 65% more TPNH and total triphosphopyridine nucleotide than control animals maintained at an ambient temperature of 250 ± 10 C. The significance of these alterations to the efficiency of oxidative pho...
