Williamsburg Salt Spa tends to the corporeal conundrums of clients with the help of more than 15 tons of salt rocks that have been imported from Pakistan and Poland and arranged in a relaxing environment. In the course of a 45-minute session spent lounging in reclining chairs in the unique microclimate of the spa's salt room, succor seekers (up to eight people per public session) naturally absorb an array of powerful minerals through their skin and inhalations, much as a sponge absorbs water and a football coach absorbs Gatorade. The body boosters include sodium, which is known to improve the skin, and magnesium, which can help battle stress. Other minerals—such as iron, iodine, and potassium—can provide many health benefits, including boosting the immune system and relieving respiratory problems brought on by allergies or pollution. Light music and warm air soothe sodium-soakers as they breath in the saturated air, helping relax away the tension of workplace quarrels with intransigent fax machines.
