-
Sun
damage is cumulative. All the doses
of ultraviolet radiation (UVR) received
by the skin, large or small, add up:
the total dose leads to skin wrinkling,
altered pigmentation and skin cancer.
-
There
is no such thing as a 'healthy tan'.
Tanning is a response to skin injury
by UVR.
-
Avoid
sun exposure between the hours of 10
a.m. to 3 p.m.
Plan outdoor activities for the early
morning or late afternoon.
-
Wear Protective clothing,wear a hat and apply
sunscreen to any remaining unprotected
skin.
-
Apply
sunscreens even on overcast days.Although
UVR is less intense on overcast days.
-
Beware
of sun exposure at high altitudes. In
the mountains there is less atmosphere
to absorb UVR, and therefore the risk
of sunburn is greater.
-
UVR
is strongest near the equator, where
the sun's rays strike the earth most
directly.

- UVR
is reflected by sand, concrete and snow,
and reflected UVR adds to the total exposure.
Because UVR is reflected and scattered,
sitting in the shade does not necessarily
protect from sunburn.
- Although
sun beds emit mostly UVA, over-exposure
can still cause sunburn, and their use
enhances skin aging and the risk of skin
cancer.
- People
at high risk for skin cancer (persons
with skin types I and II, outdoor workers,
and persons with a history of skin cancer
or a photosensitivity) should use sunscreens
daily, and should never 'sunbathe'.
- Keep
babies out of the sun. Begin using sunscreens
on children as soon as they learn to walk,
and then allow sun exposure with moderation.
- Teach
children sun protection early.
- Use
a good-quality skin care product, such
as a moisturizer containing sunscreen
ingredients with an SPF factor of at
least 15, and active against UVA and UVB.
Use it regularly, everyday.
