Why do many people, especially women, avoid the sun in Asian countries?
The major reason is probably fear of darkening the skin, a purely aesthetic concern, as most Asian women prefer white skin. The second reason is the association between skin cancer and ultraviolet exposure.

What damage can excess sun cause?
Pre-cancerous (actinic keratosis) and cancerous (basal cell carcinoma, squamous cell carcinoma and melanoma) skin lesions – due to decreases in the skin's immune function. Benign tumors. Fine and coarse wrinkles. Freckles.
