Figure 1: Salivary cortisol concentrations during waking hours following sleep at home or sleep in the lab. Daily profiles were assessed by having subjects provide multiple samples throughout the day, beginning immediately upon awakening and finishing prior to going to sleep. Samples were provided following sleep at home (Baseline), the 1st and 2nd nights in the sleep laboratory (Lab1 and Lab2) and again once subjects resumed sleeping at home (PostLab). *Statistically significant difference of Location, P<0.05; †Statistically significant difference between Lab1 and Baseline, P<0.05; ‡Statistically significant difference between Lab 2 and baseline, P<0.005.
