Longevity & AgingFirst Wearable to Track Cortisol Continuously Could Transform Stress and Metabolic Health
A California startup called Adaptyx Biosciences has introduced the first wearable device capable of continuously measuring cortisol over multiple days in humans. Cortisol is a hormone that regulates energy, metabolism, blood pressure, immune function, and stress response — yet until now, it could only be measured through single-point blood, saliva, or urine tests. At the American Diabetes Association's 86th Scientific Sessions, Adaptyx presented early human data showing the device accurately tracked cortisol changes, including the natural morning surge known as the cortisol awakening response. For anyone interested in sleep quality, metabolic health, or stress management, continuous cortisol monitoring could provide an entirely new window into how the body's hormonal rhythms affect daily health and long-term disease risk.
