I used to be a runner, but have had a lot of knee trouble these past few years, and am looking for ways to help with my joints and cardio health. I try to walk 10k steps every day, but am looking to add something more to my routine. I read that IR saunas have cardiovascular benefits? And an article claims that the heat stress can mimic moderate intensity walking or other exercises in terms of heart rate and blood flow.

I occasionally use the sauna at the gym after a workout, but haven’t been consistent enough to notice any changes in my health tracker. Interested to know if there’s any truth to these claims and if anyone has health stats to back it up?
