Key summary

Wearable technology often misreads menstrual cycle symptoms as overtraining or sickness due to a lack of understanding of the underlying physiology. This article explores how wearables track the menstrual cycle, from sensors to algorithms, and the accuracy gap that exists.

TL;DR

  • Wearable technology often misreads menstrual cycle symptoms
  • Resting heart rate increases during the luteal phase
  • HRV decreases during the luteal phase
  • Skin temperature shifts due to progesterone's effect
  • PPG sensors capture heart rate and blood volume
  • Machine learning algorithms classify cycle phases
  • Accuracy gap exists due to lack of understanding of physiology
  • Cycle-aware algorithms are needed to improve accuracy
