Physical and occupational therapists, rehabilitation and pain management specialists, and a host of other medical professionals using warm paraffin wax for the heat treatment of arthritis, inflammation, strains, muscle spasms, and more.
What paraffin wax does is, it provide heat to relieve muscle stiffness and joint pain. At the time paraffin wax loses its stored heat, blood vessels will absorb heat and expand. This caused more blood circulation to the affected area.
Increase circulation means more oxygen at the cellular level. A temporary increase in the pain threshold, a decrease in muscle spasms, and an increase in flexibility occur, significantly benefitting the outcome of therapeutic range of motion exercises.
