Abstract: slope) throughout the study. CV autonomic modulation was assessed using indices of heart rate and blood pressure variability. CV onset times for all indices did not differ significantly from DLMO (p > 0.05). Mean differences between DLMO and CV onset time were significantly correlated with the phase angle of entrainment (all significant, r > +0.75). Our results suggest that CV autonomic transition into biological night was not associated with DLMO, which seems to depend on the phase angle of entrainment.
