Student’s t-test analyses ( Table 2 ) revealed HF- vs .-LF differences only at 18.00 h ( p = .02), with differences at 30 min post-waking and at midnight being close to significance ( p = .11 and p = .07, respectively).

Among the subjects who responded to mental stress (baseline-to-peak increment >1.5 nmol/L; n = 13, 5 LF, 8 HF), the amplitude of cortisol response and the steepness of recovery decline displayed an increasing trend in the HF subjects, although between-group differences failed to reach the threshold for significance.
Between-group differences, albeit showing a clear trend, failed to reach the threshold for significance.
