Overview

• Sunburn is an inflammatory burn caused by UV radiation damaging skin cells, leading to redness, swelling, pain and itching.
• Blisters form natural protective barriers over damaged skin and should not be self-drained, with only a dermatologist deciding if they need to be opened to prevent infection.
• The six recommended immediate care steps are moving indoors, applying cooled compresses wrapped in cloth, using lightweight moisturizers, staying hydrated, taking over-the-counter pain relievers and tracking the UV index.
• The Bundesamt für Strahlenschutz advises protecting skin and eyes with sunscreen and head coverings at UV index values of three and above and seeking shade or avoiding midday sun when the index reaches eight.
• Experts warn that although sunburn heals visibly, the UV-induced cellular damage persists and contributes to long-term skin cancer risk.
