Hot-cold compress options come in many different varieties. Selecting the right one is a matter of considering the needs of the individual, how long the compress is expected to last, and on what area of the body the compress will be used. Most hot-cold compresses are designed to be used more than once and have the capability of offering heat as well as cold to damaged tissue for first aid and other therapies. The varying temperatures have specific functions in aiding the body's healing process. Hot compresses are most often used to alleviate muscle aches, cramping and arthritis discomfort, while cold compresses are ideal for insect bites, sprained joints, and bruises.
The chemical make up of a hot-cold compress is normally a simple saline, or salt, solution. When frozen, the mixture serves as a flexible yet cold compress capable of retaining its low temperature for varying length of time, depending on external circumstances. It is important to never place a cold or frozen compress directly on exposed skin. With microwaveable hot-cold compresses, the same salt mixture is heated to produce a hot pack capable of holding the correct temperature for an hour or more.
Hot-cold compresses are available in many different varieties. Reusable compresses are normally heated in the microwave, and chilled in the freezer. A reusable hot-cold compress, when taken care of, can effectively be used for months and possibly even years. Single-use compresses are also available. They are often smaller and ideal for alleviating pain and swelling of a small area, but because they are disposable, the cost of using these hot-cold compresses can add up quickly.
There are a multitude of uses for hot compress function of a hot-cold compress. Heat therapy increases blood flow and provides pain relief. This type of compress therapy is especially useful in relieving stiff joints and sore muscles, and is often employed by physical trainers and therapists in a number of different situations. It is also not uncommon for doctors to prescribe hot packs to their arthritis patients to promote greater range of motion and to enhance the effects of pain relieving and anti inflammatory drugs. Warm, moist heat penetrates into tissue more deeply than dry heat, and is thus more effective in treating these kinds of muscle and joint problems.
Issues such as tendon or ligament injury, bruising, and head or toothaches can be improved with cold therapy. Cold temperatures impede the flow of blood to a specific area of the body, making it difficult for swelling of the tissues to occur. With reduced blood flow, the sensation of pain is reduced, helping speed up the healing time associated with injuries or illnesses involving swelling. Ice or cold packs can also be employed in minor first aid situations when the patient has light or moderate bleeding. Serious injuries will require a visit to the doctor's office or local hospital.
