Why HRV Is the New Longevity Obsession
Heart rate variability (HRV) has moved from elite‑sports labs to mainstream wellness apps, with devices like Oura, WHOOP, Garmin and Eight Sleep reporting daily scores to millions of users. The metric, once a clinical predictor of post‑heart‑attack mortality, is now a daily “readiness” number that influencers and celebrities tout, prompting a surge in consumer interest, especially among young women. Experts caution that HRV’s baseline is highly personal and that obsessively chasing higher numbers can paradoxically increase stress. Properly used, HRV can flag illness or over‑training, but it is not a universal performance shortcut.
