The warmth can reduce pain and discomfort associated with osteoarthritis, chronic joint stiffness and persistent musculoskeletal conditions. The heat can also help patients to tolerate movement in stiff fingers, thumbs, wrists and toes more comfortably, which is particularly helpful before mobility exercises. By warming superficial tissues and reducing discomfort, wax treatment may help patients achieve better movement during subsequent exercises, stretching and functional activities.

Superficial heat causes local vasodilation, increasing blood flow to the warmed area. This is a temporary physiological response, rather than evidence that the treatment speeds tissue healing. The wax can soften dry skin and may help patients relax, a useful additional benefit for hands and feet affected by chronic stiffness.
