What Is Cold Therapy?
At its core, cold therapy is the use of cold temperatures to reduce pain, swelling, and inflammation in the body. It’s sometimes referred to as:
-
Cold compression therapy (when cold is combined with compression)
-
Cryotherapy (a broad term that also includes whole-body cryotherapy in clinics)
-
Cold packs, ice packs, or cold therapy wraps (at-home methods for targeted relief)
Cold therapy works by lowering the temperature of the skin and underlying tissues. This cooling effect slows down blood flow, numbs irritated nerves, and reduces swelling in the injured area.
Cold Therapy vs Cryotherapy
It’s important to note that “cryotherapy” can mean different things. Clinical cryotherapy chambers use subzero air for whole-body exposure, while at-home cold therapy wraps (like Vortech 58°F™ wraps) deliver safe, targeted cooling to a specific joint or muscle group. Both methods reduce inflammation, but at-home wraps are designed for daily, repeatable use that fits into recovery routines.
Why Cold Therapy Wraps Are Different From Ice Packs
Traditional ice packs and frozen gel packs can be messy, uncomfortable, and hard to keep in place. In contrast, cold therapy wraps are designed to:
-
Conform ergonomically to knees, shoulders, and other joints
-
Deliver consistent cooling without “freezer burn”
-
Stay in place so you can move around
-
Offer adjustable compression for faster swelling reduction

How Cold Therapy Works — The Science
So how does something as simple as cold help with pain and swelling? The answer lies in the body’s natural response to temperature changes.
Vasoconstriction and Reduced Blood Flow
When you apply cold to the skin, blood vessels constrict (narrow). This slows blood flow to the injured or surgical area, which in turn reduces swelling and bruising. Less fluid leakage means less pressure in the tissues — and less pain.
Nerve Activity and Pain Relief
Cold also affects the way nerves send signals. By slowing the conduction of nerve impulses, cold therapy decreases the sensation of pain. This is why even a short session can provide relief that lasts beyond the time the wrap is on.
Inflammation Control
Inflammation is the body’s natural healing response, but too much can delay recovery. Cold therapy limits excessive inflammation so healing tissues can repair more efficiently. That’s why surgeons and physical therapists almost universally recommend cold therapy in the first days and weeks after surgery.
The Power of Cold + Compression
Research shows that combining cold with compression is even more effective at reducing post-surgery pain and swelling than cold alone. A wrap that delivers both at the same time can shorten recovery timelines and improve comfort.
Cold Therapy vs Heat Therapy — When to Use Each
One of the most common recovery questions is: Should I use ice or heat? Both therapies play an important role in healing, but they’re used at different stages.
When to Use Cold Therapy
Cold therapy is best for:
-
Acute injuries (sprains, strains, fractures)
-
Post-surgical recovery (especially first 72 hours)
-
Swelling or inflammation
-
Joint pain or arthritis flare-ups
-
After intense workouts (to reduce soreness and muscle micro-tears)
Think of cold as the go-to for “new” pain, swelling, or irritation.
When to Use Heat Therapy
Heat therapy, on the other hand, is best for:
-
Stiff muscles and joints
-
Chronic pain (like long-term back pain or arthritis stiffness)
-
Relaxation and circulation improvement
-
Before activity or stretching (to loosen muscles)
Heat increases blood flow, which helps with stiffness — but it can worsen swelling if applied too early after an injury or surgery.

How Long & How Often to Use Cold Therapy
The effectiveness of cold therapy isn’t just about applying it — it’s about using it at the right frequency and duration.
General Guidelines
-
Typical session: 15–20 minutes at a time
-
Frequency: Every 2–3 hours during acute pain or swelling
-
Total daily use: 3–5 times per day as needed
Always allow the skin to return to normal temperature between sessions to avoid overcooling.
Post-Surgery Protocols
Surgeons often recommend a structured routine after procedures like ACL repair, knee replacement, or rotator cuff surgery. This usually involves:
-
First 72 hours: Very frequent icing (every 2–3 hours)
-
Weeks 1–2: 3–4 sessions per day
-
Weeks 3+: As needed for pain and swelling
👉 For a full breakdown by procedure, see our in-depth guide: Cold Therapy After Surgery: A Recovery Timeline.
Safety Considerations
-
Never apply cold directly to bare skin (always use a wrap or fabric layer).
-
Limit single sessions to 20 minutes.
-
Avoid use if you have poor circulation or nerve damage unless cleared by a doctor.
