Baseline characteristics of participants. Bedtime and Wakeup time—habitual sleep and wakeup times according to sleep diary; Time in bed—time between bedtime and getting up time according to actigraphy; Chronotype score according to CTQ. Data are presented as mean ± SEM for women and men participants divided by age (<40—women/men younger than 40 years; ≥40—women/men 40 years and older).
