I Stopped Using the Oura Ring… Here’s Why

Is the Oura Ring a medical breakthrough or just an expensive sleep tracker? After 90 days of testing the Oura Ring during 12 hour urgent care shifts and cageside at mixed martial arts events, I break down the clinical reality of this $400 biohacking device. In this video, we go beyond the Silicon Valley hype. As a board certified physician, I analyze the underlying photoplethysmography (PPG) technology, compare the ring's sleep stage accuracy to clinical EEG sleep labs, and reveal what happens to your Heart Rate Variability (HRV) during extreme adrenaline spikes. If you are an athlete, entrepreneur, or high performer trusting your recovery to a wearable, you need to understand the data it is getting wrong.
