What is the first step when performing first aid for a sprained ankle?

The first step in providing first aid for a sprained ankle is to rest the affected area and apply ice. Resting helps prevent further injury and allows the inflammatory process to begin without additional strain on the joint. Ice is a crucial component as it reduces swelling and numbs the area, which alleviates pain.

Applying ice should be done for intervals of about 15-20 minutes at a time, ensuring that the ice pack is not directly on the skin to avert frostbite. This initial care aims to manage symptoms and promote healing right from the start of the injury.

Other options like keeping weight on the ankle can worsen the injury, while applying heat may increase swelling and pain during the initial injury phase. Wrapping the ankle tightly may also risk restricting blood flow and increasing swelling, which is not advisable immediately following a sprain. Therefore, resting and icing the ankle effectively addresses both pain and swelling, laying the groundwork for successful recovery.
