Sun sensitivity refers to the skin's heightened reaction to ultraviolet (UV) rays from the sun. People with sun sensitivity may experience redness, itching, or rashes after sun exposure, even with minimal sunlight. This condition can be caused by various factors, including genetics, certain medications, or underlying health issues. Individuals with conditions like lupus or rosacea may be more prone to sun sensitivity. To manage this sensitivity, it is essential to use broad-spectrum sunscreen, wear protective clothing, and seek shade during peak sun hours. Regular skin checks can also help monitor any changes or reactions.
