UV radiation (sun exposure) and Skin cancer |
Both UVA and UVB rays contribute to skin damage, including skin cancer. UVB radiation is known to cause damage to the DNA of skin cells. Skin cancers develop when this damage affects the DNA of genes that control growth and division of skin cells. Recent research has found that UVA also contributes to skin cancer formation.
UVA and UVB radiation, What is the difference?
Sunlight consists of two main types of harmful UV radiation: UVA and UVB
UVA:The "Aging" rays (95% of all rays)
UVA rays penetrate more deeply into the skin. It causes long term deep tissue damage such as elastin and collagen breakdown, wrinkles, age spots, and lost of skin firmness. It results in signs of premature aging and may lead to skin cancer. UVA persist year-round; penetrate on cloudy days and through glasses and clothes.
UVB:The"Burning" rays (5% of all rays)
UVB rays reach the skin surface, causing sunburn and skin aging. It is more prevalent during the summer.
What is" Broad-spectrum" sunscreen?
It protects from both UVA and UVB rays. SPF is a measure of UVB protection only not UVA protection. The SPF of a sunscreen relates only to the protection you receive from UVB rays. That's why you need a sunscreen labeled "broad-spectrum" so you make sure to protect against both UVA and UVB radiation.
Why should you use sunscreen?
Sunscreen helps protect from:
- Skin cancer
- the damaging UVA and UVB rays of the sun
- Painful sunburn
- The signs of premature aging (up to 90% )
- fine lines, wrinkles, uneven skin tone and permanent skin discoloration
What is SPF (Sun Protection Factor)?
The SPF of a sunscreen tells you how long a product will protect your skin, if you apply sunscreen correctly. For example, when using an SPF 30, you get the equivalent of 1 minute of burning UV rays for each 30 minutes you spend in the sun. So spending 8 hours in the sun wearing SPF 30 sunscreen is the same as spending 16 minutes unprotected. Remember, sunscreen does not give you total protection.
Facts you must know about sunscreen use
- SPF- higher SPF protects your skin for longer period of time when exposed to sun. Use sunscreens with an SPF factor of 15 or more
- Areas- use it on areas of skin exposed to the sun, particularly when the sunlight is strong
- Cloudy days- use it also on days that look overcast too, since clouds are able to block only 20% of radiation.
- Prolonged sun exposure- sunscreen should not be used to allow you to sit in the sun longer. Remember that although sunscreens may help reduce your exposure to UV light they will not prevent melanoma if you get too much exposure, particularly if you have other risk factors
- Apply properly- Remember: Sunscreen Only Works When Applied Properly
- Apply before sun exposure- Apply sunscreen 20 to 30 minutes before going outside. Many sunscreens don't become effective for 20 to 30 minutes
- Reapply- most sunscreens need to be reapplied about every 2 hours or after perspiring, swimming or toweling off.
- "Waterproof" or "very water-resistant" labeled products provide protection for 40 to 80 minutes when swimming or sweating
- Expiration date- After expiration date products are less effective
- Amount used- An average adult should use about one ounce of sunscreen to cover arms and legs, and a teaspoon each for neck and face. And don't forget to protect your lips with an SPF 15+ lip balm.
- Most common mistakes- are using too little sun block and waiting to long to reapply
Practicing sun safety to help prevent skin cancer?
It's important to spend time outdoors, but by incorporating some common-sense protective measures, we can play outside while still minimizing our exposure to UV radiation.
What should I look for in a sunscreen beyond SPF?
Sunlight consists of two main types of harmful UV radiation: UVA and UVB. UV-Burning rays cause sunburns. UV-Aging rays penetrate deeper to cause skin damage and premature aging.
Sunscreen is just one part of a sun-healthy lifestyle
The best ways to lower the risk of non-melanoma skin cancer are to avoid intense sunlight for long periods of time. You can continue to exercise and enjoy the outdoors while practicing sun safety at the same time.
- Learn facts about sunscreen. ( see above)
- Avoid the sun between 10 a.m. and 4 p.m.
- Seek shade: Look for shade, us umbrella, especially in the middle of the day when the sun's rays are strongest
- Liquid intake: stay well hydrated in the sun
- Practice the shadow rule and teach it to children. If your shadow is shorter than you, the sun's rays are at their strongest
- Slip Cover up with protective clothing to guard your skin as much as possible when you are out in the sun. Choose comfortable clothes made of tightly woven fabrics that you cannot see through when held up to a light
- Uae a hat: Cover your head with a wide-brimmed hat, shading your face, ears, and neck. If you choose a baseball cap, remember to protect your ears and neck with sunscreen
- Wear sunglasses with 99-100 percent UV absorption to provide optimal protection for the eyes and the surrounding skin.
- Protect your kids: Skin cancer risk increases with life long accumulative effect of sun exposure
