Day 20. Today I want to show data from two different wearable devices, Oura ring and WHOOP band, and compare them with a device from Empower Sleep that is used for home sleep studies. You can see the device on my finger in yesterday‘s post. By continuously monitoring vitals, it was able to pick up almost 30 episodes of oxygen desaturation with accompanying spikes in heart rate. While other nights were not as bad as this one, I now have a diagnosis of mild to moderate obstructive sleep apnea. In
