How long should you apply ice to an injury?

Applying ice to an injury for 15-20 minutes every hour as needed is the best practice because it effectively reduces swelling and relieves pain without causing skin damage. This duration is long enough to constrict the blood vessels and limit inflammation but not so long that it risks frostbite or skin injury. The recommended timing allows the tissues to cool significantly and provides ample recovery time before further applications are made.

This method aligns with common recommendations in sports medicine and first aid practices that emphasize controlled cooling as a way to manage acute injuries. It helps in minimizing tissue damage and accelerating the healing process while ensuring comfort for the injured individual.
