Published on

Ultraviolet (UV) rays are an invisible form
of radiation. They can penetrate your skin and damage your skin cells. Sunburns
are a sign of skin damage. Suntans aren't healthy, either. They appear after
the sun's rays have already killed some cells and damaged others. UV rays can
cause skin damage during any season or at any temperature. They can also cause
eye problems, wrinkles, skin spots, and skin cancer.

To protect yourself:



-- Stay out of the sun when it is strongest
(between 10 a.m. and 4 p.m.)


-- Use sunscreen with an SPF of 15 or higher


-- Wear protective clothing


-- Wear wraparound sunglasses that provide 100
percent UV ray protection


-- Avoid sunlamps and tanning beds

Check your skin regularly for changes in
the size, shape, color or feel of birthmarks, moles and spots. Such changes are
a sign of skin cancer.
