Abstract

An experiment was conducted to assess sleep and circadian regulation in an astronaut. Sleep was recorded polygraphically on tape as was body temperature. Daytime alertness was subjectively rated by a mood questionnaire. For a comparison, the same parameters were measured during a baseline period preceding the flight. The circa- dian rhythms of body temperature and alertness were found to be de- layed in space compared to baseline. This could mark a phase shift or the transition to a circadian state of free-run. Sleep was shorter and more disturbed. The structure of sleep was significanly altered. In space, REM-latency was shorter, there was less REM sleep in the second non-REM/REM cycle, and slow wave sleep was redistributed from the first to the second cycle.
