Salt Spa is operated by Dr. Nita Desai, a family physician, holistic medical doctor, and certified Ayurvedic practitioner who believes that halotherapy is as therapeutic as it is relaxing. It's certainly the latter: clients laze upon adjustable lounge chairs in the halotherapy cave, meditating or even napping as soft music plays in the dimly lit space. As they rest, their lungs absorb salted air, the purpose of which is to encourage mucus production and cilia function in order to expel pollens, viruses, and toxins from the body. The removal of stagnant mucus is also said to soften the effects of many chronic conditions, including asthma, sinusitis, allergies, and hay fever. The source of this therapeutic air is the two tons of salt that cover the walls and floor of the cave, plus the halogenerator, a device that grinds the compound into a dry aerosol that circulates throughout the room on tiny helicopters.
