If you’ve never treated yourself to a spa day before, taking a bath in wine, milk, or mud can sound far from appealing. But such treatments are believed to have significant health and beauty benefits. They’re also pleasurable and relaxing. If you’re considering a trip to the day spa, here are a few treatments worth indulging in.

Balneotherapy. This term refers to bathing in order to bring about a medical benefit. It actually encompasses many common immersion-based spa treatments, including mud baths, vinotherapy, aromatherapy, and hydrotherapy. During the bath, the patient is immersed in a substance-usually wine, water, milk, or mud. There are often herbs and essential oils included. These are believed to have physiological and psychological health benefits.

Mud therapy. Taking a bath in mud might seem a bit strange at first. But the mud used in spas is not the same stuff you track in the house if you forget to wipe your feet. It’s “clean” mud, usually clay-based and specially formulated to draw impurities out of the skin. It can be applied during facials or full-body baths. Many spa-goers are surprised at how good it feels to indulge in a mud bath-and how great their skin looks afterwards.
