As many as 60,000 people worldwide die each year from too much sun, but simple safety steps could prevent many deaths, according to a World Health Organization report.

The report, released on Wednesday, was treated as the first overall look at the global health burden from UV radiation, which is linked to up to 90 percent of melanoma（恶性黑色素瘤） and other skin cancers. UV radiation can also cause sunburn, more rapid skin aging, eye diseases, and reactivation of the herpes（疱疹） virus that causes cold sores, and pterygium, a fleshy growth on the surface of the eye.

“We all need some sun, but too much sun can be dangerous—and even deadly,” said Dr Maria Neira, the director of WHO’s agency of public health and the environment, who released the report.

To prevent cancer and other diseases linked to UV radiation, the agency recommends that people:

— Limit time in the midday sun.

— Use shade wisely and seek shade when UV rays are most intense.

— Wear protective clothing, hats and sunglasses.

— Use sunscreen with a sun protection factor 15+.

— Avoid sunlamps and tanning parlours.

People under age 18 should not use them at all.

“The application of sunscreens should not be used to prolong sun exposure but rather to protect the skin when exposure is unavoidable,” the report warned.

The report also noted that the ground’s surface can make a difference:

— Fresh snow reflects as much as 80 percent of ultraviolet light.

— Sea foam reflects about 25 percent.

— Dry beach sand reflects about 15 percent.

Small amounts of exposure to the sun help the skin to produce vitamin D.
