What should you know about sunburn in shade?

A tree, umbrella, balcony, or shade sail can reduce direct sunlight without creating a complete ultraviolet barrier. Open sides allow light to scatter in, while sand, water, glass, and pale paving can reflect it toward the skin. Redness and warmth may appear later, followed by tenderness, blisters, or peeling. Sunburn is separate from long-term sun-damaged skin, although repeated exposure can contribute to both. See [Sunburn](/conditions/sunburn/) and [Sun-Damaged Skin](/conditions/photoaging/).

Move into deeper shade or indoors, cool the skin with a damp cloth or lukewarm shower, and apply a fragrance-free moisturiser to intact skin. Wear loose, soft clothing and avoid more ultraviolet exposure until discomfort settles. Do not puncture blisters or scrub peeling areas. Cover exposed skin with clothing and use sunscreen on uncovered areas when you must go outside. [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) may help restore comfort in dry, irritated skin.

Seek medical advice for widespread blisters, marked swelling, severe pain, infection signs, or symptoms that keep worsening. Get urgent help for fainting, confusion, repeated vomiting, severe headache, inability to drink, or painful eyes and vision changes. A clinician may advise whether [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) are appropriate; do not apply them to broken or infected skin without guidance.

Ask whether the shade structure you use blocks ultraviolet light, which exposed areas need extra coverage, and how to care for blisters or peeling. Mention any photosensitising medicines and ask when normal outdoor activity is reasonable.
