Oxygen in blood - saturation??

[Horse]

My Garmin (and presumably lots of other people's) does O2 sat and heart rate all the time.

My watch is a Fitbit Versa 4. The app blurb says it only records O2 while I'm asleep, averaged over 3 hours. Also that sleeping O2 is lower than daytime.

Re accuracy, the watch threw an attack of the ab dads a couple of weeks ago.

Also I just looked up resting beats per minute and surprisingly I'm generally in the above average fitness line for my age mostly, sometimes average (did get to good once!! LOL).



Good job I don't take this seriously I am so not above average in fitness!!

I'd be taking a massive pinch of salt with that one. mostly because it puts me in excellent / athlete category

Me too.

Speaking of measuring stuff and trends, my bathroom scales measure weight, fat content, water content and calculate BMI. Only really measured them once (when I got them) but, prompted by this thread I did them again. I'm 'healthier' than when I got them. (Pretty much middle of 'normal' ranges but slightly low on moisture but I did do it v first thing in the morning).
