6 Cold Therapy Myths You Should Stop Believing
Cold therapy is one of the most common and effective tools in post-injury and post-surgical recovery. From reducing swelling to managing pain, cold therapy — when used correctly — can speed healing and improve comfort. Yet misconceptions persist. At Supply Physical Therapy, we’ve spent nearly 30 years working with clinicians and patients, and we see the same myths over and over. Here are six cold therapy myths you should stop believing — and what the research and experts actually recommend.
Myth 1: Cold therapy prevents healing
Truth: Cold therapy reduces inflammation and pain, which can support the healing process when used appropriately. Short-term vasoconstriction limits swelling and bleeding after injuries and surgeries. It’s important to balance cold therapy with other treatments and follow provider guidance.
For post-operative protocols and clinical guidance, see our resource on why cold therapy is essential for post-surgery recovery.
Myth 2: Ice packs are as good as a cold therapy machine
Truth: Traditional ice packs can be helpful for short-term relief, but dedicated cold therapy machines and cold-compression systems offer more consistent temperature control and longer treatment windows. Machines like the DonJoy Iceman Clear3, Breg Polar Care Wave, and the Polar Care Cube provide regulated cold and compression to manage swelling over hours — something a gel pack can’t reliably do.

Myth 3: The colder, the better
Truth: Extremely cold temperatures can damage tissues and delay recovery. Effective cold therapy maintains a therapeutic temperature to reduce pain and swelling without causing frostbite or skin injury. Many modern devices have safety settings to maintain optimal temperatures — for example, the Omni Ice Pulse Compression and Cryodynamics ARC Iceless systems that manage temperature and, in some models, integrate compression for added benefit.
Myth 4: Cold therapy is only for acute injuries
Truth: Cold therapy is useful for acute injuries and post-operative swelling, but it also helps chronic conditions by controlling flare-ups and managing pain. Devices like the Breg Polar Care Kodiak and Aircast Cryo Cuff have pads and wraps designed for repeated use on chronic joint issues and arthritis management.
Myth 5: You should apply cold directly to skin
Truth: Always use a barrier such as a thin cloth or the integrated liner on machine pads. Direct ice can cause frostbite or cold burns. Most high-quality pads and wraps are designed to be applied over surgical dressings or directly to skin safely. Browse cold therapy pads and replacement wraps in our Breg cold therapy collection or explore Omni Ice accessories for compatible liners and straps.
Myth 6: Cold therapy is only for athletes
Truth: While athletes use cold therapy for performance and recovery, it’s equally important for everyday patients — seniors recovering from joint replacement, people recovering from surgery, and workers with repetitive strain injuries. Our range includes portable options for home use, like the Polar Care Cube, and hospital-grade machines for clinical settings. Read case studies and rehab tips in our blog series on integrating cold therapy into recovery, such as Cold Therapy 101.
Practical tips for safe and effective cold therapy
- Follow your provider’s timing guidance — typical cycles are 15–20 minutes, repeated every 1–2 hours in the first 48–72 hours after injury or surgery.
- Use a barrier between skin and ice to prevent frostbite; most machine pads are made for safe direct application when used correctly.
- Choose the right system for your needs: portable gel wraps for convenience or machines like the Breg Polar Care Glacier and Aircast Cryo Cuff for longer, regulated therapy.
- Consider cold-compression systems when swelling and inflammation are primary concerns — options include the Breg Polar Care Wave and the Omni Ice Pulse Compression.
