Description
Summary: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 greater blood flow through exposed parts. The Eskimos showed an elevation of basal metabolic rate and of plasma and total red cell volume. There are similarities between the circulatory changes found in the Eskimo and those found in hyperthyroidism.
