Ive alway used the sauna, since my wrestling days. I only do it once or twice a weekat my age now (47) for about 15 to 20 mins. Helps u bring ur core temp up a little, helps me sweat out metals and toxins, stretch out my tendons and joints real well while im in there, and lose a little extra water, make sure u take in xtra water. Just my opinon, has always really worked well for me!!!
