Cold compresses are necessary treatment tools for most minor sports injuries. Application of a cold compress reduces both swelling and pain in soft tissue that has been traumatized, thereby shortening healing time for most sprains, strains and bumps. You may be tempted to create your own cold compress by simply putting ice in a sandwich bag or by using a bag of frozen vegetables. While these methods will do in a pinch, there are advantages to using commercially manufactured cold compresses specifically designed to treat these minor injuries.
Homemade ice-packs and compresses are likely to melt quickly, and can cause "ice burn," a condition in which the top layers of skin are frozen and thereby damaged, sometimes severely. Also, it can be difficult to balance or secure a homemade ice-pack so as to maximize its effectiveness.
Specially manufactured cold compresses are generally made from a gel which remains pliable, even when frozen. This pliable gel remains frozen longer than ice itself after being applied to warm skin. And since cold therapy is delivered in conjunction with compression and elevation, cold compresses that meld to the skin and are easily secured in place are preferable.
What to Look for
The type of cold compress you keep on hand is going to be determined by the type of injuries you are preparing for in a certain setting. For general, home use, reusable compresses are available that can be put in the freezer or the microwave to be used hot or cold. For situations where you do not have a freezer, "instant" compresses are available. Instant cold compresses provide cold by means of a chemical reaction that occurs when an inner bag is burst.
Common Pitfalls
While it is less likely that you will acquire ice burn from a commercially-made cold compress, it is still vitally important to read the directions and note whether or not it is safe to apply the compress directly to the skin. If you are in doubt, always wrap the cold compress in a paper towel, wash cloth, flannel or any other cloth you do not mind getting wet. It is unlikely that the compress will leak, but the condensation that forms on its outside will often soak the wrapping.
Also, if using a one-time, disposable compress that is activated when an inner bag is burst, be sure to throw away the used compress when you are finished with it. As handy as it is to store these since they do not require an ice-chest or freezer, it is time consuming and annoying to reach for one, only to discover it has already been used.
