What Is Sleep Tracking Actually Measuring and When to Trust It?

Emma Sullivan and David Park break down what sleep trackers actually measure—movement and heart rate, not brainwave activity—and why that matters for interpreting your nightly scores. They explore when tracker data is genuinely useful (spotting patterns over weeks, not judging individual nights) and when it backfires, causing "orthosomnia," the anxiety of obsessing over sleep metrics. Listeners will learn how to use these devices as pattern-finding tools rather than report cards, and when to trust their own sense of rest over a number on their wrist.Follow The Wellness Rhythm Show:  ▶️ YouTube: https://www.youtube.com/@TheWellnessRhythmShow  📖 Newsletter: https://thewellnessrhythmshow.substack.com  Powered by VoxCrea.AI
