Radio Headspace Sleep Data, Decoded with Dr. Aric Prather
Mar 13, 2026
A lively breakdown of how wearables infer sleep from movement, heart rate, and breathing. A clear look at why sleep-stage readings can be misleading compared with lab measurements. A cautionary segment on orthosomnia and how data anxiety can worsen sleep. Practical ideas for using trackers as behavior-change tools and for running simple personal experiments.

Episode notes
Wearables Track Sleep Time Well But Not Brain Stages
- Consumer wearables reliably detect sleep versus wake because they track movement and signals like heart rate.
- Dr. Aric Prather explains labs use scalp electrodes to measure true sleep stages, which consumer devices currently estimate indirectly.
Patient Obsession With Screenshots Caused Orthosomnia
- A patient repeatedly showed screenshots claiming he had no deep sleep and feared Alzheimer's, fueling distress.
- Dr. Aric Prather used the example to show tracking data can worsen insomnia by increasing anxiety about sleep.
Orthosomnia Is Insomnia From Tracking Obsession
- The term orthosomnia describes insomnia driven by hyper-focus on wearable sleep data.
- Dr. Aric Prather cites Kelly Barron coining the term and links device-driven distress to worsening sleep.
