Does your Apple Watch keep reminding you to breathe? You’re not alone. People all over the world are interrupted by the Apple Watch reminding them to breathe every day — even if they’re already breathing. So what gives?

One of the most common misconceptions about Breathe alerts is that they are related to stress. The idea is that the Apple Watch detects when you need to take advice from Taylor Swift and calm down.

I don’t suffer from this confusion (I “breathe” with the app when it’s convenient but give it no further thought) but this is a good primer into what’s going on behind the scenes.
