Abstract
Rectal and skin temperatures of two young Caucasian males were recorded in Arctic winter conditions for fourteen nights - the first two nights under neutral conditions, the next ten nights while sleeping outdoors in an unheated tent, and the final two nights under neutral conditions. One had a "quiet" sleep and allowed his body to cool, thus decreased heat loss. The other showed an insomnia accompanied by many body movements, and also maintained his body temperatures. A speculative hypothesis based on the interrelationships of biogenic amines was advanced to explain the observed differences in thermoregulation.
