A sweat lodge detoxifies the body by stimulating blood circulation and causing you to sweat out impurities. You are typically naked or wrapped in a towel.
A traditional Native American sweat lodge is dome-shaped and circular, and built low to the ground. Rocks are heated up in a fire outside the lodge, then brought into the center of the lodge with a shovel and placed in a dug pit. More rocks are brought in, traditionally in four rounds, and the Indian sweat lodge gets progressively hotter.
The person in charge of the ceremony "pours the water" and is responsible for the health and well-being of participants. Typically there are 8 to 12, but there can be as many as a few dozen. Find out how to stay safe in the sweat lodge.
Pouring water on the rocks creates steam, which makes the Native American sweat lodge feel even hotter. Sweatgrass or sage is scattered on the rocks. You might be smudged with sage smoke before entering the Indian sweat lodge, to aid with the ritual purification. It is usual to offer up prayers, share your thoughts with others, and ask for the release of pain and suffering.
The traditional Native American sweat lodge is not that common at spas. New Age Health Spa in Neversink, New York, offers sweat lodge ceremonies once a month from April through October, on the Saturday closest to the full moon. Skana Spa in upstate New York has a sweat lodge, but you have to wear swimsuits.
