Selective SWS suppression does not affect the time course of core body temperature in men

Abstract
SUMMARY  In eight healthy middle‐aged men, sleep and core body temperature were recorded under baseline conditions, during all‐night SWS suppression by acoustic stimulation, and during undisturbed recovery sleep. SWS suppression resulted in a marked reduction of sleep stages 3 and 4 but did not affect the time course of core body temperature. These data suggest that sleep stages 3 and 4 of nonREM sleep (i.e. SWS) do not play a major role in the regulation of core body temperature in humans.
