From personal experience, cardio will absolutely lower RBC/Hematocrit. It takes time though.I don't think cardio will fix it. From what I've read, cardio may lead to blood clots and stroke in patients with high rbc. Same holds true for any strenuous activity for people with thick blood. As posted above, blood letting or reduction in rbc creating foods is about it.

I've never heard of cardio increasing clots and strokes, in what population? Any lit citations? Only time its been an issue, maybe is in endurance athletes abusing EPO and getting dehydrated.I don't think cardio will fix it.

Same. I would run 15-35 miles a week when in the Corps and RBC/HCT were always normal. I retired and 6 months later when I did my physical my RBC/HCT shot through the roof. Everything remained the same except I was no longer doing cardio. Doc said start doing cardio again, so I started doing 30-60 minutes of slow steady state cardio every day. After 6 months my RBC/HCT were back in normal range. Had a relapse in cardio and RBC/HCT were above normal again. Now I am doing 20-60 minutes cardio every day, either HIIT or slow steady state. I am back in the normal range and have stayed there.From personal experience, cardio will absolutely lower RBC/Hematocrit. It takes time though.
