‘You’re going to be surprised’: Why you should wear a watch with heart rate sensor

“I think it’s pretty safe to say that it’s not going to cause an issue for anyone, especially if you wear a good watch,” said Lisa Krawczyk, who works as a health consultant in Houston.

“I would expect that any device that uses it, whether it’s a smartwatch or not, would have a heart rate monitor that is working properly.”

Krawczyks said a smart watch can have a wide variety of features, but a watch that’s designed for a single function should not be an issue.
