ABSTRACT
The ovulatory menstrual cycle is characterized by hormonal fluctuations that influence physiological systems and functioning. Multi-sensor wearable devices can be sensitive tools capturing cycle-related features pertinent to women's health research. This study used the Oura ring track changes in sleep related features, also tracked self-reported daily functioning symptoms across regular, healthy cycle.Twenty-six women (age, mean (SD): 24.4 (1.1 years)) with cycles (length, 28.57 (3.8 days)) were monitored a complete cycle. Four phases, reflecting different hormone milieus, selected for analysis: menses, ovulation, mid-luteal, late-luteal. Objective measures of sleep, distal skin temperature, heart rate (HR) vagal-mediated variability (HRV, rMSSD), derived from ring, subjective diary (eg quality, readiness) compared phases.Wearable-based continuity stages did not vary Women reported no perceived quality or readiness only marginally poorer mood midluteal phase. However, they moderately more physical during menses (p < 0.001). Distal temperature HR, measured showed biphasic pattern cycle, increased HR 0.03) body 0.001) mid- late-luteal phases relative ovulation. Correspondingly, rMSSD HRV tended lower luteal Further, was ovulation = 0.05).The accompanied significant objective mood, cycles. other evident may longitudinally over multiple natural setting.
