Experimental timeline for both sleep-deprived trial (left panel) and normal sleep trial (right panel). Acute cold exposure always occurred between 0600 hours and 0800 hours, followed by rewarming from 0800 to 1000 hours. Sedentary activities were permitted for the remainder of the trials.

Physiological and perceptual responses to a 53-hour period of sleep deprivation (SDEP) and normal sleep (CON). (A) Rectal temperature (Tre); (B) mean skin temperature (Tsk); (C) oxygen consumption (VO2); (D) thermal sensation. Mean ± SD. *Significant difference between SDEP and CON. Acute cold exposure (ACE [in 10°C) always occurred between 0600 hours and 0800 hours, followed by rewarming (RW [in 25°C]) from 0800 to 1000 hours.
