Muscle Recovery & Pain Relief: The aluminum plate of the mini massage gun head rapidly cools in just 3 seconds (within a range of 46-57 °F / 8-14 °C, adjustable in 4 levels). Cold compression contracts muscles and reduces blood circulation, alleviating muscle swelling and diminishing muscle soreness. This feature is particularly effective for post-exercise muscle recovery.
