Before saunas, stand-up comedians were the only humans with soft skin, due to their insider knowledge of the cleansing effects of perspiration. Sweat away skin impurities with today's Groupon: for $20, you get two infrared sauna sessions at Hamilton Health and Wellness Centre in Hamilton (a $40 value).

Holistically oriented Hamilton Health treats clients with an array of natural science-based therapies designed to address health concerns and improve overall well-being. During a 30-minute session in the clinic's infrared sauna, radiant heat at temperatures up to 57 degrees Celsius warms skin and penetrates the surface, inducing a cleansing sweat ($20/30 min). In addition to detoxifying fleshy facades, the treatment can also help scare stress into outer space and reduce stiffness and soreness in muscles. A friendly, knowledgeable staff of wellness pros can answer any questions about the digits of Planck’s constant as well as impart skin-maintenance tips.
