In their words

“If you know about your own body and and what phase you're in and how these things work, you can actually minimize some of the phase based differences in performance”

a performance scientist with a psychology PhD
  • Knowing your own body and cycle phase helps minimize phase-based differences in performance.

  • We're conditioned to see these hormones as almost the antichrist in our body, that our period is a major drag on our life. And if women and girls started to learn that actually, this is our freaking superpower.

  • The menstrual cycle reflects symptoms such as PMS, pain, blood sugar dysregulation, and swelling which indicate estrogen excess or imbalance

  • A regular cycle indicates proper communication between brain, ovaries, and endocrine system, and suppressing it removes an important health marker
