While weight loss is achieved from a sauna suit, it is not considered a healthy option. "Sweating excessively has no useful purpose in health weight loss." The heat stress placed on the body simulates hot weather. According to the American Heart Association, extreme heat can cause heat exhaustion, heat stroke and dehydration. Additionally, extreme fluid loss can disrupt sodium and electrolyte levels, leading to brain damage and kidney failure, as well as cardiovascular distress.
