Mobile health service is promising to detect the blood pressure and HRV fluctuations across the menstrual and the lunar cycle

Here we report on experimental feasibility and preliminary results on mobile health services to detect enigmatic effect of the lunar cycle (LC) on heart rate variability (HRV) parameters and blood pressure (BP) in young females, with respect to the menstrual cycle (MC). We found that the MC exerted strong effect on varied HRV parameters specifically in the ovulation phase. Unlike the MC, the LC presented only tiny and non-significant, though still notable, effect on BP and HRV seen primarily in the full moon phase. We hypothesize on potential usability of e-medicine services, such as mobile-nested on-line day-to-day monitoring of electrocardiogram (ECG) for HRV, as a research tool for a longitudinal experiment with ultimate goal to detect the LC impact on human circulation system. Would such hypothetic effect experimentally been found, a mobile medicine services could be invented which allows user synchronizing the MC with the LC for better awareness on current physiological status and planning of daily activities and reproductive behavior.
