Apple confirms Watch OS update tweaks heart rate monitoring

If you’re an Apple Watch owner with a keen interest in your health and fitness, you might have noticed some odd changes in heart rate monitoring since the rollout of Apple Watch OS 1.0.1. Apple has confirmed that these changes are intentional, and the device is now monitoring heart rate less regularly as a deliberate feature rather than a bug.

Back in the days of Watch OS 1.0, heart rate was recorded every 10 minutes. Now — as users had noticed and Apple has now confirmed with an updated support page — readings aren’t taken as frequently if your arm is moving or your whole body is in motion. The tweak is probably aimed at eliminating erratic readings during exercise, but not all users are happy.

As Apple has already discovered, the technology behind heart rate monitoring is difficult to get right in a device as small as a smartwatch — that’s why many serious athletes invest in a separate chest strap. It’s worth noting that the Apple Watch also includes a separate Workout app, which can provide regular heart rate readings, if required.

So, if you were wondering why your Apple Watch and associated Health app have been behaving differently, now you know. The Watch OS 1.0.1 update also improves the speed of third-party apps, and is able to more accurately track activities such as walking and cycling.

We’re expecting more Apple Watch news once WWDC kicks off from June 8 as well. There might be announcements about the availability of standalone Apple Watch apps (that don’t require an accompanying iPhone app) as well as HomeKit improvements that could put the smart timepiece at the center of your connected home. We should get our first look at iOS 9 too.

Are smartwatches and fitness trackers making us more anxious?

In a recent Apple Watch ad, one of the protagonists is shown taking an electrocardiogram (a test that can be used to check your heart's rhythm and electrical activity) on his watch while riding a bus, working at the office, and even while hanging out at a kids' pool party. The commercial’s message is clear: The latest Apple Watch is so powerful that you can run advanced medical tests anywhere in seconds. The question is: Do you need to?

Although smartwatches have made health insights more accessible than ever and motivated many to adopt fitter lifestyles, their rise has come at a cost. It has sparked a wave of anxiety among users who have become pathologically fixated and prone to over-diagnosing every alert from their wearables.

Dr. Lindsey Rosman, a clinical health psychologist and an assistant professor of cardiology at the University of North Carolina at Chapel Hill, says her clinic has observed a growing number of patients with concerns about the information they receive from their smartwatches.
