Common Limitations
- Sleep stage detection less accurate than polysomnography
- Cannot diagnose medical sleep disorders
- Affected by device positioning and fit
- May increase sleep-related anxiety
Accuracy Comparison
| Metric | Consumer Device | Clinical PSG | Accuracy |
|---|---|---|---|
| Total Sleep Time | Wearable/App | EEG monitoring | 85-95% accurate |
| Sleep Stages | HRV + Movement | Full polysomnography | 70-85% accurate |
| Sleep Efficiency | Time in bed vs awake | EEG + movement | 90%+ accurate |
| Sleep Disorders | Pattern recognition | Clinical diagnosis | Screening only |
