## TL;DR

- Wearables are best at spotting deviations from your personal baseline: resting heart rate, skin temperature, breathing patterns, sleep and activity can all surface early warning signals.

---

## Summary

- Wearables are best at spotting deviations from your personal baseline: resting heart rate, skin temperature, breathing patterns, sleep and activity can all surface early warning signals.
- The strongest clinical case is AFib detection. In one Apple Watch study, irregular pulse alerts were confirmed as atrial fibrillation 84 percent of the time.
- Weaker signals include blood pressure alerts, calorie estimates, sleep stages, VO2 max, HRV and proprietary readiness or recovery scores. Doctors often cannot act on them directly.
- AI coaches from Google, Oura and Whoop aim to make sensor data easier to understand. Useful as a nudge toward testing or a doctor visit, not as a diagnosis.

## Nauti's Take

This is useful AI as long as expectations stay grounded. Wearables can notice patterns people miss, but they are limited at explaining cause and context. The industry likes to sell health certainty, while often delivering probabilities inside polished app cards. Strong as a signal layer; weak as a wrist-based substitute for a doctor.
