I've seen this subject pop up in articles a few times now, as if someone is trying to make people stop using heart rate monitors? From what I've been reading from ME patient testimonials, heart rate monitors are one of the most helpful devices in self care. So I feel like these studies totally overlook an important target group of heart rate monitors...

“They’re selling millions and millions of these devices and so far we haven’t demonstrated a general benefit to them.”
Other recent studies also contradict the idea that the devices benefit health. One, published last month in JAMA, found that healthy young people who wore devices were less likely to lose weight than those who didn’t; another in The Lancet Diabetes and Endocrinology found that wearing a tracker did not encourage people to exercise more.
