What Is Cold Therapy?
Cold therapy, also called cryotherapy or ice therapy, is the use of cold temperatures to reduce pain, swelling, inflammation, and tissue damage after an injury or medical procedure. It works by narrowing blood vessels, slowing blood flow to the affected area, and temporarily reducing nerve activity.
Cold therapy is commonly used during the first 24 to 48 hours after an acute injury.
Why Cold Therapy Matters
Applying cold soon after an injury can help decrease swelling, reduce pain, limit inflammation, and promote a more comfortable recovery.
