What to do: Run under cold water for at least 20 minutes. Evidence suggests that this can reduce pain and edema, reduce the depth of the burn, decrease the overall inflammatory response, improve the speed of wound healing and minimize scarring.
Pain management should be a priority: Treating pain early and aggressively has been shown to prevent psychological trauma and even to improve healing. A multimodal analgesic approach is recommended.
What not to do: Treat with ice. Ice causes severe vasoconstriction and can even deepen the burn.
