Figure 2. Salivary Cortisol Diurnal Levels.

Figure 2

Salivary cortisol at nine time points on the rest day taken upon awakening at home (Wake), immediately at arrival to the lab (Pre-Baseline; PB), min 10 and 20 of baseline (Baseline 1 and Baseline 2; B1 and B2), min 15, 30, and 45 corresponding to the stress protocol (Stress 1, Stress 2, and Stress 3; S1, S2, S3), 30 min poststress (Recovery; R), and at home before bedtime (Bed). HC+ women had significantly lower salivary cortisol levels at Wake (p < 0.05), but significantly higher levels from Baseline 1 through Recovery (p < 0.001) than HC− women during the morning session (Group x AM/PM x Time, F(8/1176) = 2.73, p<0.01). There was no difference between HC groups in the afternoon session. Hormone levels are reported as mean ± SEM.
