## TL;DR

- Wearables are strongest at spotting deviations from your own baseline: resting heart rate, skin temperature, breathing, sleep and activity can together flag changes before symptoms are obvious.

---

## Summary

- Wearables are strongest at spotting deviations from your own baseline: resting heart rate, skin temperature, breathing, sleep and activity can together flag changes before symptoms are obvious.
- Only a small set of features is clinically solid today. Atrial fibrillation alerts are among the most useful; one Apple Watch study confirmed AFib in 84 percent of irregular pulse notifications.
- Other metrics remain shaky: blood pressure alerts, calories, sleep stages, VO2 max, HRV and readiness scores are rough signals, not medical findings.
- AI coaches from Google, Oura or Whoop may explain patterns and nudge earlier care, but much of the logic is proprietary and hard for doctors to verify.

## Nauti's Take

This is less Star Trek medicine than an early warning system with a marketing problem. Good wearables do not tell you what disease you have; they tell you that something no longer matches your normal pattern. That can be valuable if the app stays humble and the doctor does not become an optional footnote. The best role for AI here is not oracle, but translator between raw signals, daily context and the next sensible step.
