9 Apple Watch Health Features That Fly Under the Radar, According to a Doctor at Apple
The Apple Watch includes several underutilized health features that can provide valuable insights into users' well-being. Dr. Lauren Cheung, a doctor at Apple, highlights tools like the Vitals app, noise monitoring, and ovulation estimates as potentially life-saving. These features use advanced sensors to track metrics such as heart rate, environmental noise, and temperature changes for proactive health management.
- ▪The Vitals app uses overnight metrics like heart rate, wrist temperature, respiratory rate, and sleep duration to monitor health trends and send alerts when readings are out of range.
- ▪The Noise app measures environmental sound levels and can notify users when they are exposed to potentially harmful noise, helping protect hearing health.
- ▪Ovulation estimates are enabled by advanced temperature sensing on Apple Watch Series 8 and later, using tiny temperature shifts to identify ovulation and improve period predictions.
- ▪Users must wear the Apple Watch consistently for at least seven days to establish baseline readings for the Vitals app.
- ▪The Cycle Tracking app requires setup through the Health app with fertility predictions enabled to provide ovulation estimates.
