Warriors use this time to work on themselves. They are also provided massage therapy, workout room and state of the art Infrared Saunas. Dr. Jeffrey Lieberman, MD, has completed two studies in which he had people with major depression sit in an infrared sauna. In his first study, the participants had just one infrared sauna treatment and it reduced their symptoms by about 50%. In his followup study, he found that a single session caused a rapid and powerful antidepressant effect, and the benefits continued for six weeks, which was unexpected. He concluded that whole-body hyperthermia holds promise as a safe, rapid-acting, antidepressant treatment with a prolonged therapeutic benefit.
