Using ice to treat injuries is one of the oldest methods of pain control. Proven to be safe and effective at reducing swelling, relieving pain and decreasing muscle spasms, ice therapy is an easy self-care technique that anyone can administer. Every mother knows to put ice on a bruised knee after a soccer game or on a teething toddler’s tender gums. But do you really know how ice works?
Cold therapy, also known as cryotherapy, works on the principle of heat exchange. This occurs when you place a cooler object in direct contact with an object of warmer temperature, such as ice against skin. The cooler object will absorb the heat of the warmer object. Why is this important when it comes to cold therapy?
