Quick answer: Cold therapy for sports injuries may temporarily ease pain and help manage swelling after a new sprain or strain. Wrap a gel ice pack in a thin towel and apply it for up to 20 minutes at a time. The NHS advises using ice every 2 to 3 hours during the first 2 to 3 days for sprains and strains. Cold therapy can support short-term comfort, but it does not diagnose an injury or guarantee faster healing.
How cold therapy helps after a sports injury
Cooling an injured area can temporarily numb pain. For an acute sprain or strain, ice is one part of the NHS PRICE approach: protection, rest, ice, compression and elevation. It is a way to manage symptoms while the injury settles, not a treatment that repairs a torn ligament or muscle by itself.
How quickly an athlete returns to sport depends on the injury and recovery plan. Do not use reduced pain after icing as proof that it is safe to train or compete. If movement, swelling or pain is not improving, get advice from a qualified health professional.
How to use a gel ice pack safely
- Put a barrier between the pack and your skin. Wrap a frozen gel ice pack in a thin towel or cloth. Do not place ice directly on bare skin.
- Keep each session short. Apply for up to 20 minutes, then remove the pack. For sprains and strains, NHS guidance suggests repeating every 2 to 3 hours during the first 2 to 3 days, as needed.
- Check your skin. Stop if the area becomes unusually painful, burns, or develops concerning color or sensation changes. Let the skin return to its normal temperature before another application.
- Stay awake and follow the product directions. Do not fall asleep with a cold pack on, and do not wrap it so tightly that it restricts circulation.
The American Academy of Orthopaedic Surgeons also advises limiting ice applications to 20 minutes, using a cloth to reduce direct skin contact, and avoiding ice when circulation is poor.
Choosing a cold pack for an injury
A reusable gel ice pack can be convenient because it can be refrozen and may flex around areas such as an ankle, knee or shoulder. Choose a size that covers the sore area comfortably, keep a cloth barrier in place, and use the pack according to its care instructions. A pack’s flexibility or coldness does not mean it will heal an injury faster.

Pair cold therapy with a recovery plan
For the first 2 to 3 days after a sprain or strain, the NHS recommends protecting and resting the injured area, using ice, adding comfortable support with a bandage, and elevating the area when possible. A bandage should not cause numbness, tingling, increased pain or a change in skin color. When you can move without pain stopping you, gentle movement can help prevent stiffness. Follow a clinician’s advice for serious injuries or a return-to-sport plan.
When to avoid ice or seek medical help
Ask a health professional before using cold therapy if you have poor circulation, reduced sensation, or a condition that makes you unusually sensitive to cold. Do not use an ice pack as a reason to delay an assessment when symptoms are severe.
Seek urgent medical help if you heard a crack, the injured area looks deformed, you have numbness or tingling, the skin turns blue or grey, pain or swelling is severe, or you cannot bear weight. These symptoms can need prompt assessment and may indicate a more serious injury.
Cold therapy questions athletes ask
How long should I leave an ice pack on?
Use it for up to 20 minutes at a time with a cloth between the pack and your skin. Remove it sooner if it causes burning, unusual pain or concerning skin changes.
Can cold therapy make a sports injury heal faster?
Cold therapy may help with short-term pain and swelling, but it cannot promise faster tissue healing or a quicker return to sport. Recovery depends on the type and severity of injury and appropriate rest, assessment and rehabilitation.
How often can I use a gel ice pack?
For sprains and strains, NHS guidance says up to 20 minutes every 2 to 3 hours during the first 2 to 3 days. Your clinician may recommend a different plan for your injury.
