As wearable health tech becomes more common, understanding the limits of its accuracy matters for people making health decisions based on it. The takeaway isn't to distrust the devices entirely, but to use them as trend indicators rather than precise medical measurements.
- Wearable sleep trackers may not report exact, clinically accurate numbers.
- Doctors still see value in these devices for tracking personal sleep trends.
- Users should interpret sleep data as relative patterns rather than absolute truth.
