Research results suggest changes of physiological parameters such as heart rate, respiration, skin conductance response, sleep duration, sleep quality and skin perfusion during the menstrual cycle. Latest fitness trackers allow to conveniently and non-invasively record these parameters. The present study aims to evaluate whether there is a correlation between physiological parameters and the menstrual cycle i.e. ovulation as measured by a urine ovulation test and the onset of menses. To collect data women will wear two smartwatches and a smartshirt at night. All three devices are CE-approved for sports and fitness.

Condition Intervention
Device: Participants wear a sensor bracelet for collecting physiological data and conducted urine tests to estimate the day of ovulation

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Variations of Physiological Data Throughout the Menstrual Cycle

Primary Outcome Measures:
  • Correlation between menstrual cycle dynamics and physiology [ Time Frame: During 1 menstrual cycle between 24 days and 35 days ]
    Correlation between a combination of the physiological parameters heart rate, respiration, skin conductance response, sleep duration, sleep quality and skin perfusion and menstrual cycle dynamics.
