$25 for a 45-Minute Salt Cave Session and 30-Minute Infrared Sauna Session from Medical Frontiers Spa (a $60 Value)

A dose of fresh salt air is rumoured to be good for the lungs, which is why all mariners have the enormous lung capacity needed to perform rousing sea shanties in canon. Today's WagJag is certainly worth its salt in benefits: get a 45-minute salt cave session and 30-minute infrared sauna session at Medical Frontiers Spa for only $25 (regularly worth $60).

Halotherapy (or salt therapy) is a well-documented treatment with a host of health and beauty benefits. Medical Frontiers' unique salt cave recreates the atmosphere of natural salt mines through the use of halogenerators, lining the therapy rooms with pure Dead Sea and Himalayan sodium chloride, along with other useful minerals. Simply breathing in the air of these rooms has been shown to alleviate symptoms of several respiratory problems, such as chronic bronchitis, sinusitis, secondary smoke coughing and respiratory allergies, among others. It can help with a wealth of mental wellness issues and has even been productive in saving skin from the ravages of age, acne and psoriasis. Afterwards, spend a half-hour in the spa's infrared therapy sauna to promote circulation and immune function. Both systems are safe for all ages.
