Is Sauna Really Good for Blood Pressure?

I think having a cold shower or a cold bath is very good for blood pressure. I definitely feel so much more relaxed and like, the next day I feel amazing after I do it every time. During the cycling thing that I get with Chris, he was like one or two of the days there was a sauna and it was like, it was like a relief. It was like God, I felt so ready the next day. No, I totally get it. This is like, this is like me eating salad because I think it tastes good. And then I'm like, Oh, actually it is really good for you. So I just don't find it a pleasant experience.
