Cold Therapy Packs

Cold therapy or cryotherapy, works by temporarily reducing nerve activity and decreasing blood flow to the wounded area. This process significantly reduces inflammation and swelling that causes pain. 

There are different applications, the most common one is applying an ice pack or cold pack directly to the affected area. Although you can apply the ice pack several times a day, it should not be applied for more than 20 minutes at a time.


There are many types of ice packs that can be used for pain relief. The most common types include:

Single-use ice packs contain two bags inside. One bag is filled with water and is inside the other bag containing ammonium nitrate and calcium ammonium nitrate. Once the inner bag of water is broken by squeezing the ice pack, it will dissolve the chemicals on the outer bag. An endothermic reaction will occur. This reaction absorbs the heat from the surroundings, lowering the ice pack's temperature almost instantaneously.
