Ultraviolet radiation can damage skin and eyes even when the air does not feel extremely hot. WHO recommends sun-protection measures when the UV index reaches 3 or above.
Use layers of protection
Shade, clothing, a broad-brimmed hat and sunglasses reduce UV exposure. Sunscreen is an additional layer rather than permission to stay in strong sun indefinitely. Reapply according to the product instructions, especially after swimming, sweating or towelling.
Children need particular care
Young skin is especially vulnerable to UV injury. Build sun-safe habits early and avoid intentional tanning. Tanning beds and sunlamps also expose skin to harmful UV radiation.
Have new, changing, bleeding or persistently irritated skin lesions assessed. People with many atypical moles, previous skin cancer or strong family history may need more structured surveillance.
