WHOOP on Lifespan with Dr. David Sinclair

Which brings me to a wearable that I'm particularly fond of, partly because of its scientific foundation at Harvard, where I work, but also the founder's own research and scientific rigor. I'm talking about the WHOOP band, which is the one that I rarely take off my wrist. This wearable is a health and fitness coach that gives me insights into my sleep, recovery, and my body's strain. Researchers have studied how accurate the device is, and in a 2022 study, they compared six wearable devices, including WHOOP, against clinical grade ECGs and sleep recording devices. WHOOP showed strong accuracy for heart rate and heart rate variability, two measurements that are really important. Wearing the WHOOP over the last two months, I've seen dramatic improvements in my personal biomarkers. For example, my resting heart rate has gone down to 45, which is quite a low number for me. And my heart rate variability, which you want to be high, has shot up to 90, putting me in the top few percent for my age.
