What is the best substance to use on a burn?

1. Burn ointment

2. Aloe vera gel

3. Cool water

4. Petroleum jelly

The correct answer is: Cool water

Using cool water is the best immediate treatment for a burn because it helps to cool the affected area, which can alleviate pain and prevent further tissue damage. The cool temperature helps to stop the burning process and can reduce swelling. It's important to use cool, not cold, water, as extreme temperatures can exacerbate the injury. In addition to cooling the burn, immersing the area in cool water or running cool water over it for several minutes can promote healing and soothe irritation. Proper initial care with cool water is crucial for all types of burns, including first-degree burns, for which the skin is red and painful, and even for more serious burns to minimize damage. While other substances like burn ointments or aloe vera gel may have their uses in later stages of burn care or for certain types of burns, they are not as effective as immediate cooling with water for alleviating pain and stopping the burning process right after the injury occurs. Petroleum jelly should generally be avoided on fresh burns as it can trap heat and bacteria, delaying healing.
