Hi
I'm an unusual case. I had a Bima heart bypass at 48 (52 now) That's when they leave the grafting and plug both chest arteries into the heart.
Supposed to have a pacemaker and beta blockers, Ace inhibitors. I have managed with none of these.
I bike about 100 miles a week, walk daily and have a Fenix 6 Pro.
My stress reading is usually just under 50. my body battery bombs to 5% and stays there.
But when the recent problems started, my stress levels dropped a little and my body battery would charge around 40- 50% sleeping. Would even go up while I was watching a film.
As of two days ago it's gone back to being stuck on 5%. Nothings changed I monitor my heart with medical equipment.
So while Garmin were off line my stress read about 20% lower.
However I know this reading to be far more accurate than the current (usual) readings.
Just thought I would post this as I can compare the Fenix to facts.
I use a chest strap when riding (dualhr) and it's about perfect, WHR struggles over 120 I find, it's quite accurate up to then.
