AFib patients using wearable devices are more likely to engage in high rates of symptom monitoring and experience anxiety than non-users, a study shows.
If anything I have the opposite with my garmin watch that shows my heart rate. I've gotten used to seeing what my heart rate does just before I have a panic attack. This has really helped me 'catch' myself before it happens and calm myself down. I've not had one for over 2 years.
In a similar vain, I tried out a garmin smartwatch for a while, and at some point it warned me I was getting stressed.
I wasn't though - I was excited about a project that I had been working on coming together. But apparently the watch could only think in negative moods.
For that, and other privacy and usability based reasons, I decided to return it and go back to my non-heart-rating Pebble Time Steel.
