Abstract
Five male volunteers (ages ranging from 20 to 25 years) slept one screening night and one baseline night (except for one subject) in a standard sleep laboratory. They then slept in a cold room maintained at -20C for one adaptation night (breathing air) followed by six non-consecutive series of two nights with combinations of single or double sleeping bag and 0%, 2% or 4% CO2. The order of conditions was counterbalanced across subjects and the single and double bag conditions provided cold exposure manipulation. Standard polysomnography and 10 locations of body temperature was monitored. For all four subjects who had an adaptation night at normal temperature there was a decrease in total sleep time, sleep efficiency, REM sleep and sleep satisfaction when sleeping in the cold. All showed increases in REM latency. TRUNCATED
