Steam is a versatile substance—its vaporous clouds have been harnessed to clean upholstery, power locomotives, and torture recalcitrant broccoli. Steam out your stressors with today's Groupon: for $10, you get a one-day admission pass to Dillons Russian Steam Bath in Chelsea (a $20 value). The baths are open to women only on Mondays from September through May and to men only on Tuesdays through Sundays year-round. The spa is closed on Mondays from May through September.

Since 1885, Dillons Russian Steam Bath has been steaming stress out of its patrons, making it one of the oldest traditional Russian baths in the United States. Using the time-honored methods of the banya, Dillons' steam chamber seeks to subdue stress and tension with heated granite rocks, billowing steam, and sponges of cold water for invigorating dousing. At its balmiest, the upper bench of the steam room can reach as high as 180 degrees, promoting a healthy, skin-softening sweat and a bevy of ulterior body benefits.

In addition to the steam service, Dillons woos its warmed patrons with plenty of showers, a slight nostalgic longing for the Cold War, and a large lounge with a big-screen television for sprawling out after a steam. Patrons can also partake in traditional oak-leaf platza treatments in the Russian Room, an exfoliating, skin-tightening experience ($13), and a Russian massage ($25 for 30 minutes, $45 for 60).
