How can I improve the accuracy of my sleep data?

Sometimes my WHOOP doesn’t seem to recognize when I fall asleep or wake up. Are there any settings I can adjust or best practices to improve the accuracy of my sleep tracking?

Hi Emily,

To improve sleep data accuracy try following these steps…

Snug fit is key: wear it about 2–3 fingers above your wrist bone with the LEDs hidden to keep the sensor steady.
Consistency matters: sleep with it on every night so it can track things like HRV, respiratory rate, and movement around the clock.
Keep your sleep space chill: literally and figuratively. Fewer disruptions = cleaner data.
Check trends, not just one night—WHOOP updates your sleep baseline over time, so patterns are more telling than one-off results.
Use the AI Sleep Coach: it gives you personalized bedtime and wake-up tips to help you recover like a pro.

Stick with these habits, and WHOOP will serve up sharper insights into your sleep and recovery.
