What is the recommended first aid for a first-degree burn?

The recommended first aid for a first-degree burn is to apply cool running water. This method helps to lower the temperature of the skin and alleviate pain or discomfort caused by the burn. Cool running water can effectively cool the area, promote healing, and prevent further skin damage. It's important to ensure that the water is not ice-cold, as extreme temperatures can exacerbate the injury rather than assist in its recovery.

Using cool running water for at least 10-20 minutes is commonly advised, as it can provide long-lasting relief from pain and help reduce swelling. This approach is consistent with general first aid guidelines for treating minor burns, as it focuses on soothing the area and preventing complications.

While other options such as ice pack application, ointment application, and covering with a cloth have their uses in different contexts, they are not the most effective immediate response for first-degree burns. Ice can cause further tissue damage, ointments may be inappropriate right after a burn, and simply covering the burn without cooling does not address the immediate need for pain relief and cooling.
