A common heat therapy treatment, a paraffin bath involves the application of warm paraffin wax to a specific part of the body, like hands, feet, joints, and muscles. The wax is gently melted in a small tub-like self-heating appliance large enough for feet or hands to be submerged. Kept at a mild 125-135 degrees, melted paraffin is generally very safe for your skin.
The body part being treated is quickly dipped into the wax; heat from the wax transfers to the affected area as the wax solidifies. Once the wax dries, the dipping procedure is repeated until the layer is five to ten mm thick (less than ? of an inch)
