Relieve sunburn by applying a cold, wet towel to the skin, moisturizing with aloe vera or soy and taking ibuprofen to alleviate the pain it causes, according to the American Academy of Dermatologists. It is also important to stay hydrated while nursing a sunburn and avoid touching and picking at the blisters formed by the sunburn.
At the first sign of sunburn, it is important to get out of the sun and go indoors if possible. The immediate application of a cold, damp towel for around 10 or 15 minutes several times daily can help to take some of the heat out of the burn. A cool bath or shower can also be helpful in soothing sunburn pain; applying moisture after bathing can help trap moisture inside the skin and alleviate the dryness that sunburn causes.
Aloe vera or soy can also be soothing to a sunburn. The AAD warns that using lotions that contain benzocaine, lidocaine or petroleum can be detrimental to the sunburn and may cause further irritation. Hydrocortisone cream may be used for particularly uncomfortable spots.
Ibuprofen can help to reduce swelling and alleviate discomfort. Sunburn dries the body out, so drinking plenty of water will help replenish the body and avoid dehydration.
