Episode notes
INSIGHT

Trackers Trade Convenience For Stage Accuracy

  • Consumer trackers separate sleep vs wake reasonably well (≈70–80% vs PSG) but stage classification is harder and less accurate.
  • Devices use movement, heart-rate, respiration and temperature to approximate sleep stages.
ADVICE

Use Trackers For Trends, Not Nightly Scores

  • Use sleep tracker data to raise awareness and guide behavior changes, focusing on trends not nightly headlines.
  • If tracking fuels anxiety or obsession, remove the device or limit checking to once weekly.
INSIGHT

Orthosomnia: When Metrics Harm Sleep

  • Excessive focus on perfect sleep metrics can cause or worsen insomnia-like anxiety, a phenomenon called orthosomnia.
  • Not everyone suffers it, but clinicians are seeing it in some users of wearables.
