title: Periodicity in body temperature in man.
abstract: Body temperatures and self-assessed mood scales were recorded for 7 weeks or more by male volunteers. Auto-correlations of temperatures from the 21 subjects show evidence of a significant peak at the 20-day-interval. The self-assessed measure of 'Alertness' (from 18 of them) also shows some evidence of rhythmicity, at the 22-day-period.
