Ultraviolet Radiation - UV Sunlight contains 3 types of UV rays…

Ultraviolet Radiation - UV UVA—causes skin aging & wrinkles. Used in tanning beds. Colors skin and gives false sense of protection from the sun. UVA rays pass effortlessly through the ozone layer.

Ultraviolet Radiation - UV UVB—causes sunburns, cataracts, immune system damage, skin cancer. Melanoma may be associated with severe UVB sunburns occurring before the age of 20. Most UVB rays are absorbed by the ozone layer.

Ultraviolet Radiation - UV UVC—these rays are the most dangerous. Fortunately, these rays are blocked by the ozone layer and don’t reach the earth.

Ultraviolet Radiation - UV You can sunburn even on a cloudy day. On average, children get 3 times more exposure than adults. Concrete, sand, water, and snow reflect 85% to 90% of the sun's UV rays. Depletion of Earth's ozone continues to increase your exposure to UV rays. One blistering sunburn can double a child's lifetime risk of developing skin cancer.

Measuring Radiation Reported on a scale of 1 -11+. Lets check a few @ http://www.weather.com/ We use the UV Index Scale. Reported on a scale of 1 -11+. Take special care when the UV Index is 5-6 or higher.

Effects of UV Exposure Sunburn

Effects of UV Exposure Sunburn develops when the amount of UV exposure is greater than the protection your skin’s melanin can provide. The lighter your skin, the less melanin it has to absorb UV and protect itself. All skin, no matter the color, thickens and hardens with continued sun exposure, resulting in wrinkles later in life. https://www.youtube.com/watch?v=9Wa89-F2WvU

Effects of UV Exposure Eye Damage

Effects of UV Exposure Spending long hours in the sun with no eye protection may increase your chance of developing cataracts. Even low amounts of sunlight can increase the risk of eye disorders. UVB damage to the eyes is cumulative, so it is never too late to start protecting your eyes.

Effects of UV Exposure There are about 1.3 million new cases of skin cancer in the U.S. each year, resulting in about 9,800 deaths. Melanoma is one type of skin cancer. It is the most common cancer among women between the ages of 25 and 29.

Effects of UV Exposure Skin cancer is the most common of cancers and is largely preventable. Increased outdoor leisure time, less clothing worn outdoors, and decreased ozone levels are partly to blame.

Effects of UV Exposure Compare the underside of your arm to the topside of your arm to see the effect of sun exposure on your skin. “Sun damage” causes wrinkles, easy bruising, brown “liver” spots, and potentially, skin cancer.

Effects of UV Exposure Scientists believe sunburns can alter the body’s immune system for up to 24 hours after exposure to the sun. Repeated overexposure to UV radiation can cause more damage to the body’s immune system, even in people with dark skin. https://www.youtube.com/watch?v=kS0tzhDAAFo

Guidelines for Protection Eye Protection

Guidelines for Protection Sunglasses offer excellent protection. Make sure the lenses are designed to block out 95% of UV. Polarizing lenses and mirror finishes reduce glare, but have little effect in blocking the absorption of UV rays.

Guidelines for Protection SPF stands for Sun Protection Factor Sunscreen doesn’t offer 100% protection. SPF 30+ sunscreen blocks 96% of UV; SPF 15+ blocks out 92%. In addition to sunscreen, wear a hat, sunglasses, more clothing, and seek shade.

Guidelines for Protection Using SPF 30+ instead of SPF 15+ does not mean you can safely double your time in the sun. Apply sunscreen 20 minutes before going outside. Don’t rub it in—a light film should stay visible.

Guidelines for Protection Reapply sunscreen every 2 hours if you are swimming or sweating a lot. Fragrances and moisturizers in sunscreen may cause allergic reaction; experiment with other brands if this is a problem.

Guidelines for Protection Protective Clothing

Guidelines for Protection Choose clothes that cover your arms, legs and neck to ensure proper protection. You won’t get too hot or uncomfortable in lightweight fabrics like cotton, hemp or linen. THE BEST WAY TO PRACTICE SUN SAFETY IS WEAR SUNSCREEN!!

Guidelines for Protection Most cotton and cotton/polyester fabrics protect against 95% of UV, but are less effective if wet, faded, or aged. Dark colors are better at absorbing UV than light colors. If you choose to wear light colors, make sure the fabric is a tight weave, such as canvas.
