Evolution of an age old healing practice – how infrared saunas are battling cancer in addition to improving health and well-being. If you are like most people, hearing the word sauna triggers a very particular image in our minds. An image perhaps of a small, scorching room lined with wooden benches centered around a pile of very hot rocks and filled with strangers in towels sweating profusely. Most may consider this as too invasive and perhaps unhygienic. On the contrary, sauna is a healing tradition that dates back more than 2,000 years.
