After 10 days with the Apple Watch Series 12, I'm disturbed by one 'slightly off' reading
After more than a week of wearing the Apple Watch Series 12, I've learned at least one surprising thing about my health.
Since the release of the Apple Watch Series 12, it has evolved from a fitness gadget to a comprehensive health monitor, tracking vital signs like heart rate, temperature, blood oxygen levels, respiratory rate, and sleep patterns. The device's Vital app now provides a holistic view of overall well-being, with a Readiness score on a scale of 1 to 10.
On a recent day using my Series 12 watch, I encountered a "Slightly Off" reading in the Vitals section, specifically for a slightly elevated heart rate while sleeping. This was attributed to a heart rate of 60 beats per minute (bpm), which is slightly above my average of 51 bpm during sleep. While this single reading may cause concern, it's important to note that my subsequent measurements have been "Typical."
The new Series 12 model features a sunburst-style heart rate sensor with larger green LEDs, capable of taking readings every five seconds, which provides more accurate data compared to previous models that only measured heart rate every five minutes. Despite the overwhelming amount of data collected by the watch, I plan to continue monitoring my health and await further updates and AI features in the redesigned Health App set to release later in 2026.
