Abstract
Sleep recordings skin and rectal temperatures were taken on two young caucasian males sleeping two nights in neutral conditions then for ten nights in cold conditions and finally for two nights under neutral conditions. The sleep studies in a cold environment showed disturbances in sleep patterns, decreasing total sleep time. In parallel with the increased wakefulness and drowsiness, the most affected stage was paradoxical sleep (REMS): cold exposure caused a deprivation in REMS. The debt was immediately "repaid" on return to neutral conditions. The changes in human sleep during cold nights were generally in agreement with the results of animal studies.
