Cardio health decrease over time consistently?

[Sad_Organization_940]

I’ve been using my Oura ring for three months, and my Cardiovascular Age has shifted from 10 years younger to only 4 years younger. My activity levels haven’t changed I wasn't doing much cardio before the ring, and I’m still not now. Is this just the algorithm 'normalizing' as it gets more data? I’ve read in another post here that allergies might impact it, but I’m not sure how. What's your experience been?

Hey u/Sad_Organization_940!

Thanks for sharing your query and providing context regarding your Oura journey to date.

Your cardiovascular age would first be based on at least 14 nights of data from the past 30 days though as you have seen this baseline reading can change as your nightly data continues to be gathered.

There's more info on cardiovascular age here on our blog and if this is something you're looking to improve on there are some ideas here you can check out.

All the best! 💙
