Interpreting sleep tracker results
Smart rings and smartwatches estimate your sleep based on movement, heart rate and temperature; they don't measure brain waves the way a sleep study does. They're good for following trends but inaccurate at assessing individual sleep stages. This guide helps you make use of your device without unnecessary worry.
You will need
- A smart ring, smartwatch or sleep app
- The device's app on your phone
- A sleep diary for comparison
- A 4-week measuring period
Steps
Use the device correctly
