Steam therapy is far from a new phenomenon. For thousands of years, many different cultures have used the healing powers of steam to soothe the body and relax the mind. However, modern societies are now rediscovering for themselves the many benefits of steam and reinventing the ways in which people experience it. A growing number of owners and managers of commercial and institutional properties have embraced steam therapy—hotels and resorts, golf and health clubs, day spas, and timeshares.
