Frequently Asked Questions
What are cold hot packs?
Unlike instant cold packs, that are stored at room temperature and quickly chill themselves when needed for one-time use, reusable cold hot packs are merely a material that holds its temperature well, so they are stored in a freezer or heated in water or a microwave oven to reach the desired temperature. The first cold hot pack was introduced in 1948 with the name Hot-R-Cold-Pak and could be chilled in a refrigerator or heated in hot water. The first reusable cold hot pack that could be heated in boiling water or a microwave oven was first patented in 1973.
What are some safety concerns with cold hot packs?
Gel packs have been made with diethylene glycol and ethylene glycol. Both can cause illness if ingested in large amounts making them unsuitable for use with food. The US Consumer Product Safety Commission recalled such packs.
What are ice packs or gel packs?
An ice pack or gel cold hot pack is a portable plastic bag filled with water, refrigerant gel, or liquid. To be prepared for use, the pack is first placed in a freezer. Both ice and other non-toxic refrigerants (mostly water) can absorb a considerable amount of heat before they warm above 0 °C (32 °F) used to keep food cool in portable coolers, or as a cold compress to alleviate the pain of minor injuries, or in insulated shipping containers to keep products cool during transport.
Ice packs are used in coolers to keep perishable foods (especially meats, dairy products, eggs, etc.) below the 5–75 °C (41–167 °F) danger zone when outside a refrigerator or freezer, and to keep drinks pleasantly cool. The amount of ice needed varies with the amount of food, its initial temperature, the thermal insulation of the cooler, and the ambient temperature and exposure to direct sunlight. Ice initially well below freezing temperature will last a little longer.
Water has a much higher latent heat of fusion than most substances, and a melting temperature which is convenient and easily attained with, for example, a household freezer. Additives to improve the properties of water are often used. For example, substances can be added to prevent bacterial growth in the pack, or to prevent the water from solidifying so it remains a thick gel throughout use.
Gel packs are often made of non-toxic materials that will remain a slow-flowing gel, and therefore will not spill easily or cause contamination if the container breaks. Gel packs may be made by adding (Cellusize), sodium polyacrylate, or vinyl-coated silica gel.
When should you use a cold hot pack?
Anyone who has ever sprained or twisted an ankle or pulled a muscle knows that cold is your friend. Bruises, insect bites, and repetitive strain injuries such as tendinitis, also respond well to treatment with cold packs. Cold therapy can help people with muscle spasms, whiplash, and various forms of arthritis as well.
How does a cold hot pack work?
Cold packs are very effective at reducing swelling and numbing pain. An injury swells because fluid leaks from blood vessels; cold causes vessels to constrict, reducing their tendency to ooze. The less fluid that leaks from blood vessels, the less swelling results. Cold also eases inflammation and muscle spasms, two common sources of pain.
The sooner you apply an ice pack to a sprain or strain, the sooner it can do its job reducing pain and swelling. For chronic problems such as low back pain or muscle spasms, ice whenever the symptoms start up.
How long should you use a cold pack?
A general rule of thumb is to ice an injury over a period of 24 to 72 hours. Apply cold packs for periods of up to 20 minutes every two to four hours. When your skin starts to feel numb, it’s time to give your body a break from a cold pack.
What precautions should you take when using cold packs?
Prolonged, direct contact with cold can damage skin and nerves so always be sure to wrap your cold pack in a towel. If you have diabetes, poor circulation, or blood vessel disorders such as vasculitis or Raynauds disease, talk with a health professional before using a cold pack.
When should you use a hot pack?
Heat can increase blood flow and help restore movement to injured tissue. Warmth can also reduce joint stiffness, pain, and muscle spasms. As with cold packs, heat packs have a role in easing pain from both acute and chronic injuries, such as sprains, strains, muscle spasms, whiplash, and arthritis. Doctors often suggest using cold packs for the first day or two, and then switching to heat if the symptoms persist or become more chronic.
In fact, for some folks, nothing soothes a sore back like a hot pack. In a study published in the journal Spine, investigators at the University of Medicine and Dentistry of New Jersey found that the continuous application of low-level heat eased low back pain better than two common over-the-counter painkillers.
How long should you use a hot pack?
Apply a hot pack wrapped in a towel for 20 to 30 minutes at a time. Some physical therapists recommend alternating between heat and cold for people with painful muscle spasms or chronic problems such as arthritis.
When shouldn’t you use a hot pack?
Although you may feel tempted to apply the soothing warmth of a heat pack immediately following an injury, resist the urge. You should treat any new injury with cold for a couple of days before switching to heat. Heat actually may do more damage than good until most of the swelling is gone.
