TEMPERATURE DROP AND SLEEP - TESTING THE CONTRIBUTION OF SWS IN KEEPING COOL

SLEEP and body temperature characteristics were studied in man in base line (B), 24 h-constant routine (CR) and recovery (R) after the CR. Th e sleep advanced and deepened the trough of the minimum temperature wh en compared with CR. No relevant difference in minimum body temperatur e, or in the slope of temperature decrease was found, however, between B and R sleeping nights. No correlation was found between the amount of slow wave sleep and body cooling. The results do not support a home ostatic role of slow wave sleep in brain and/or body cooling.
