The salt of the earth refers to humble, unpretentious people—unlike the paprika of the earth, which refers to people who go great with deviled eggs. Salute pepper's paler compatriot with today's Groupon: for $20, you get a halotherapy session at Solaris Salt Spa in Mississauga (a $45.20 value, including HST).

At Solaris Salt Spa, visitors seeking stress relief or an all-natural treatment for respiratory ailments can reap the benefits of spending some quality time with sodium chloride. The spa's halotherapy sessions take place inside a quiet chamber whose walls, floor, and ceiling have been stuccoed with 6,000 pounds of Dead Sea and Himalayan salt crystals. While guests loll in lounge chairs, they soak up salt's therapeutic qualities, which can combat skin problems, clogged breathing apparatuses, and underseasoned mashed potatoes. Meanwhile, halogenerators disperse tiny sodium chloride particles into the air, making the mineral's naturally restorative effects easier to inhale. Solaris Salt Spa imparts these benefits while creating a soothing ambience complete with dimmed lights, gentle music, and restful noises provided by an on-staff humpback whale.
