第三篇：       A Native-American sweat lodge is a ceremonial sweat bath that typically has its roots in Native-American history and culture. Traditionally, it is a purifying ritual that uses intense heat to stimulate vision and insight. A sweat lodge ceremony helps detoxify 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 built low to the ground. Rocks are heated up in a fire outside the lodge and 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 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 participants, but there can be as many as a few dozen. Pouring water on the rocks creates steam, which makes the Native American sweat lodge feel even hotter. Sweet grass or sage is scattered on the rocks. You might be smudged with sage smoke before entering the sweat lodge to aid with the ritual of purification. It is usual to offer up prayers, share your thoughts with others, and ask for the release of pain and suffering.       The sweat ceremony is intended as a spiritual reunion with the creator and a respectful connection to the earth itself as much as it is meant for purging toxins out of the physical body. The ceremony is believed to free the mind of distractions, offering clarity (mental healing)； to allow for introspection and connection to the planet and the spiritual world (spiritual healing)； and to provide antibacterial and wound-healing benefits (physical healing).
