Yes my wife and I enjoy these in the cold season. Refer to the book "Outlive" for a review of sauna research. If memory serves, a 20-min sauna at 165 F several times a week produces markedly improved longevity. But as you know, grip strength is one of the best indicators of longevity. The book lists numerous beneficial practices and tests. But yeah cold plunges and sauna are great. Oh I forgot to mention, it appears research is showing the majority benefit of cold can be achieved at temp of 65F. So you may not need the ice after all. 65 can feel pretty good after being in it for about 30 seconds.
