This method quickly thaws intracellular ice crystals, halting ongoing cellular destruction, and promotes vasodilation to restore perfusion while minimizing reperfusion injury.
Never use dry heat (heating pads), massage, or rub with snow. These actions cause burns, mechanical tissue destruction from ice crystals, or further thermal injury due to absent protective sensation.
