Quick Answer
Overexposure to the sun can cause second-degree burns, also known as partial-thickness burns, which affect the epidermis and dermis layers of the skin. These burns are characterized by blisters, redness, and swelling. They require immediate medical attention.
Understanding Second-Degree Burns
Second-degree burns, classified as partial-thickness burns, can result from prolonged exposure to direct sunlight, especially when UV radiation is high. The American Academy of Dermatology recommends seeking shade or using protective measures like clothing, hats, and sunscreen with a sun protection factor (SPF) of at least 30 when spending time outdoors. However, even with these precautions, accidents can still occur.
Recognizing Second-Degree Sun Burns
Recognizing second-degree burns is crucial for proper treatment. Look for signs such as redness, swelling, and blistering, which can appear within hours of sun exposure. If you notice these symptoms, seek medical attention immediately. The burn’s size and location are also essential factors to consider; for example, burns covering a larger body surface area (greater than 10% in adults) or those located on the face, hands, or feet may have a higher risk of complications.
Treatment and Prevention
Preventing second-degree sun burns is easier than treating them. In addition to using protective gear and clothing, apply broad-spectrum sunscreen liberally and reapply every two hours or immediately after swimming or sweating. Also, stay hydrated by drinking plenty of water, especially during prolonged sun exposure. If you do suffer a second-degree sun burn, cool the affected area with cool or lukewarm water for 10-15 minutes, then apply a topical antibiotic ointment and cover the burn with a non-stick dressing.
