Abstract
Two Caucasian males, aged 19 and 22, slept at night in sleeping bags (9.0 clo) in an unheated tent at ambient temperatures between -25 and -35C in the Arctic. Electroencephalographic (EEG) sleep studies were conducted for two baseline nights (19-21C), 10 cold exposure nights and 2 recovery nights (19-21C). Rectal and skin temperatures, and heart rates were also recorded. The subjects suffered disturbances in sleep patterns involving an insomnia composed of an increased wakefulness, a decrease in slow wave sleep and a deprivation in rapid eye movement (REM) sleep. Dissimilarities appeared between the subjects which may be related to differences in thermoregulatory responses.
