Heat essentially works in the opposite way to cold therapy. It causes vasodilation and dilates the blood vessels and increases the circulation and blood flow to the area, this flushes out the inflammation and toxins and brings in new oxygen and nutrients which also speeds up efficiency of healing.

Through this heat also aids in releasing muscle tension, through warming up the muscle fibres it allows the muscle cells to relax, decreasing soft tissue restrictions and muscle fasciculation’s (spasms).
