OXYGEN CONSUMPTION AND BODY TEMPERATURES OF ESKIMOS DURING SLEEP.

The paper reports the results of measurements of metabolism and body temperatures taken during 14 nights of comfortably warm sleep in six male Eskimos from the village of Wainwright on the arctic coast of Alaska. The mean age of these subjects was 20.8 (plus or minus 1.26) years, mean height 169.1 (...

Description
Summary:The paper reports the results of measurements of metabolism and body temperatures taken during 14 nights of comfortably warm sleep in six male Eskimos from the village of Wainwright on the arctic coast of Alaska. The mean age of these subjects was 20.8 (plus or minus 1.26) years, mean height 169.1 (plus or minus 5.08) cm, mean weight 66.6 (plus or minus 2.0) kg and mean value for percent body fat 9.1 (plus or minus 1.08)%. These data show the effects of the sleep cycle on metabolism and body temperature. The sleeping metabolic rate declined from 50 (plus or minus 7.35) kcal/sq m/hr at 2230 hours to 39 (plus or minus 5.22) kcal/sq m/hr at 0600 hours. Concomitantly, rectal temperature, which was negatively correlated with time ( r = - .965393), fell from 37.0 (plus or minus .386) C at 2230 hours to 35.4 (plus or minus .386) C by 0600 hours. Calculated mean body temperature was directly related to the level of metabolic activity. These coastal Eskimos had essentially normal values for early morning basal metabolic rates in contrast to Anaktuvuk Pass Eskimos from the interior of Alaska who are hypermetabolic. (Author)
