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

For a first degree burn, the recommended first aid involves submerging the burned area in cool water. This helps to reduce pain and lower the temperature of the skin, which can prevent further tissue damage. Cool water provides immediate relief by soothing the burnt skin and can also help in reducing swelling.

Applying ice directly on the burn can cause further tissue damage and increase pain, while covering the burn with ointment may not be appropriate for first-degree burns as they usually do not require medication or heavy coverings. Leaving the burn exposed to air may increase discomfort and delay the healing process; it's often better to protect the area lightly while allowing air circulation. Keeping the burned skin cool and hydrated is crucial for effective healing, making immersion in cool water the most recommended option.
