The sauna is a traditional form of relaxation and detoxification that has been used for centuries in many cultures around the world. It is a small, enclosed room or space that is heated to a high temperature, typically between 150 and 200 degrees Fahrenheit. The heat is usually produced by wood or electric heaters, and people typically sit or lie on benches inside the sauna to sweat and relax.
Cold water immersion, also known as cold water therapy or cold water immersion therapy, is a practice that involves immersing the body in cold water for short periods of time. This can be done in a variety of ways, including taking a cold shower, swimming in a cold lake or ocean, or using a cold bath or ice bath.
