I am similar, low I guess. Usually 90-94 on my Garmin fenix 6 watch.
I wear the watch on the bottom side of my wrist to keep from scraping it, I will try it the other way...

I have year round allergies, and am usually stuffy at night and in the morning.
Lots of workouts where my nose does not breathe in that well, especially at the start.
Would these allergies lower my numbers?

58 years old, fit cyclist, do some swimming , little old man weights, and foolishly still playing basketball.
I live at 2800 feet. I will ask my doctor ahead of my yearly to see if he has any thoughts.

Now I am worrying a little.
