Paraffin wax therapy is a common option in heat therapy treatments for people with arthritis or other rheumatic diseases. The heat helps increase blood flow and relax the muscles, which can help relieve pain caused by arthritis, osteoarthritis and fibromyalgia.
The heat from the Paraffin wax also stimulates blood flow to relieve symptoms caused from Erythema Pernio (Chillblains). It can even soften hardened skin caused by scleroderma, a disease in which collagen accumulates on the body . It increases the skin's elasticity, allowing for increased movement and mobility.
For a paraffin bath, the affected area is immersed in melted wax that has been heated to 49° C. The heat can be retained by wrapping the affected area.
