Natural Cycles, the first FDA Cleared birth control app, launched NC° Sleep Insights, a sleep tracking feature specifically designed to help women understand how hormonal changes can impact how they rest and recover. "We hear from many women that they notice changes in their sleep throughout their cycle, but most sleep platforms aren’t designed to explain those patterns through the lens of female physiology," said Dr. Magda Armbruster, VP of Product at Natural Cycles. "Because Natural Cycles already helps users understand their hormonal patterns and fertility status, we’re uniquely positioned to connect sleep changes to the menstrual cycle."
To make the most of this female-first sleep tracking feature, women only need to wear their NC° Band or Oura Ring overnight so that real-time data can be collected when they rest. In the morning, users can log how they feel, and over time, take note of how they may be restless during the pre-menstrual phase and experience better nights of rest during other parts of their cycle.
