Purpose. This investigation evaluated the effects of 33 hrs of sleep deprivation on thermoregulation in six young males (29 +/- 6 yrs) and females (24.5 +/- 6.9 yrs) during 180 min of cold exposure in 12°C air. Methods. Subjects underwent two cold air trials (CAT) (12°C air for 180 min): one following a normal night of sleep (i.e., 6--8 hrs) (CON) and one following 33 hrs of sleep deprivation (SDEP). ANOVA was used to determine significance between gender and SDEP vs. CON across time for rectal temperature (Tre), mean skin temperature Tsk, metabolism (M), and insulation (I). Results. ANOVA revealed no significant differences (p > 0.05) between CON and SDEP for Tre, Tsk, HP, and I. A main effect for time was demonstrated for I, M, and Tsk. Furthermore, a significant group difference for Tsk was shown. There was no significant difference between SDEP and CON or between genders for the following hormonal variables: epinephrine, norepinephrine, cortisol, glucose, free fatty acids and insulin. A significant main effect for time was demonstrated for both norepinephrine and free fatty acids. Conclusions. There was no differential response between SDEP and CON in males or females. The only significance demonstrated was with respect to Tsk between males and females whereby females had a higher overall mean skin temperature during cold air exposure, which may indicate peripheral fatigue in females. Furthermore, SDEP combined with acute cold exposure may have masked any difference in thermal, metabolic and hormonal variables.
