A sauna is a small room or space designed to promote sweating and relaxation through exposure to high temperatures. Traditional saunas use dry heat, while steam saunas (steam rooms) use moist heat. The elevated temperatures in saunas can induce sweating, which may help release toxins from the body, improve circulation, and provide a sense of relaxation and stress relief. Saunas have been used for centuries in various cultures and are often considered a part of wellness and self-care routines.
