hellow GrannyM, and just a bit of info i was told on sauna. First, i read how its a great way to help detoxify yourself and that some have not even needed D when they have saunna'd regularly... On the other hand!!!!!!!!!!!!! Bo's dr advises STRONGLY against it. So there ya go! In other words, i have no idea
..but i do know that if you have heart issues as well, that it is for sure not recommended. Im guessing it's something you best discuss with your neph/heart dr/ or who ever else takes care of your health with you. Seems that it's one of those things that is really individual... And btw....
