Protect
yourself and your family from harmful effects of the sun.
Summer means outside time with
picnics, camping, boating – even yard work. All that extra time outdoors
though, exposes you to potentially harmful ultraviolet (UV) rays from the sun.
These rays can damage your skin in as little as 15 minutes.
Think you’re sun-savvy? Take this
quiz to test whether you know how to protect yourself from the sun’s harmful
effects.
- True or False: Unused sunscreen should be thrown out after a year.
False. According to the Centers for Disease Control,
sunscreen has a shelf life of up to three years – less if it’s been exposed to
high temperatures. Always shake the bottle to fully mix the ingredients.
- True or False: A sunscreen with a Sun Protection Factor (SPF) rating of 30 is twice as good as an SPF of 15.
False: According to the American Cancer Society,
SPF 15 sunscreens filter out about 93 percent of ultraviolet "B"
(UVB) rays, while SPF 30 filters out about 97 percent. An SPF 100 filters about
99 percent. The higher the SPF rating, the smaller the difference. However, no
sunscreen provides 100 percent protection.
- True or False: Protection from the sun isn’t necessary on a cloudy day.
False:
According to the Food & Drug Administration (FDA)
up to 80 percent of the sun's UV rays get through clouds on an overcast day.
- The sun's rays are most harmful only at noon, right?
Wrong:
According to the CDC, between 10 a.m. and 4 p.m. is the most
hazardous for UV exposure.
- I’ll use a tanning bed instead of the sun. These are OK, right?
Wrong.
According to the American Cancer Society,
tanning lamps give out UVA and usually UVB rays as well. Both ultraviolet
"A" (UVA) and UVB rays can cause long-term skin damage and can
contribute to skin cancer.
Want to have fun in the sun while
reducing the risks associated with exposure to UV rays? These suggestions can
help.
Protect yourself
If it’s cool out, don’t be fooled.
People often get sunburned in cooler weather because they don’t think about
protecting themselves if it’s not hot. Even when swimming, UV rays can reach
below the water’s surface to give you a burn.
Be especially careful if you have:
- pale skin
- blond, red, or light brown hair
- been treated for skin cancer
- a family member who's had skin cancer
Fortunately, you don’t have to avoid
the sun completely. Here are some pointers to help protect yourself and your
family.
Use sunscreen
Apply about 20 minutes before going
outside. Sunscreen should have an SPF of at least 15 and provide protection
from both UVA and UVB rays. A higher SPF number means more UVB protection (UVB
rays are the main cause of sunburn). Reapply sunscreen every two hours and
after swimming or sweating. Don’t forget sensitive spots like the tops of the
ears, nose and feet. For those who don’t have much hair, don’t forget the top
of your head!
Wear protective clothing
A long-sleeved shirt, pants, a
wide-brimmed hat and sunglasses offer great protection from the sun. Look for
hats and clothing made of tightly woven materials. If you can see light through
the fabric, UV rays can get through, too.
Sunglasses
Wear sunglasses that block UV “A”
and “B” rays. Wrap-around styles give the most protection.
Shade
The sun’s rays are strongest between
10 a.m. and 4 p.m. Find shade or go inside if possible.
Be careful around water and sand
These reflect the sun and can
actually double UV exposure.
Be careful with medications
Some prescription and
over-the-counter drugs can increase your sensitivity to sun exposure and
increase the risk of sunburn. Talk to your doctor or pharmacist about any medications
you take.
Protect children
Children tend to spend more time
outdoors and burn more easily. Be sure your child is wearing sunscreen or
protective clothing. If your child burns easily, be extra careful to cover up,
limit exposure and apply sunscreen.
If you’re concerned about the
day-to-day intensity of the sun, the Environmental Protection Agency provides a
no cost UV index by ZIP code that’s updated daily.
