I've done well & no I'm right back in it. I got a fitbit and it tracks spo2 while you sleep. Kinda worried about 95/96% sleep spo2 & Breathing rate of 17/18 bpm. If I google, these are not optimal numbers. Now I'm thinking I should get a pulse oximeter to measure it that way. (And obssess over those numbers) 🤦🏼*♀️ My husband is telling me to let it go. I do have a smoking history but I run everyday & 6 miles straight once a week. Ugh. Ive read too many Google articles. I knew the fitbit may cause me panic. I was right. Should I get a oximeter? Should I start monitoring my spo2 after runs? I don't have any symptoms when running other than the normal breathing hard & sweating. 🥴
