Why Sleep Trackers Matter for Insomnia
Understanding your sleep patterns is the first step toward improvement. Modern sleep trackers monitor heart rate variability, blood oxygen, skin temperature, and breathing patterns.
What to Look For
Accuracy of Sleep Stage Detection
The best trackers distinguish between light, deep, and REM sleep with 70-85% accuracy compared to clinical polysomnography.
Actionable Insights
Data alone does not help. The best apps correlate sleep data with daily habits like caffeine, exercise, and screen time.
