Staying in the Summer Sun
Ground-level ozone (smog) is a type of air pollution the
Illinois EPA deals with closely, especially in the Chicago area.
When summertime comes, levels of ozone increase as high
temperatures mix with emissions from industry, gasoline-powered
engines and consumer products. There is also another kind of
ozone, 35,000 feet up in the stratosphere, that protects us from
harmful ultra-violet (UV) rays. The depletion of this ozone layer
presents problems for those exposed to the sun.
Sun Tips
- Minimize sun exposure. Limit
exposure during 11 a.m. and 3 p.m. when the sun's
rays are strongest.
- Use sunscreen. Apply SPF 15 of
higher frequently.
- Wear UV protection sunglasses.
UV rays can cause eye problems, such as
cataracts.
- Cover up. Wear a hat and shirt
for protection from strong rays.
- Be aware of reflected UV rays.
On the beach, water and sand can reflect harmful
UV rays, even under hats and umbrellas.
- Use caution in tanning parlors.
Artificial UV rays can be just as damaging as
sunlight, so use good judgement as to how long
you stay under the lamp.
- Don't be fooled by clouds. Even
if the sun disappears, UV rays can penetrate
through clouds.
