    Identify ways to reduce the risk of sun damage
    List things that minimize risk of sun damage
  • 3. Why is sun protection important?
    What are the benefits of sunlight?
    What are the risks?
  • 4. How many of you use a form of sun protection when at the:
    Beach
    Park
    Afterschool activities
    Walking the dog
  • 5. Let’s see what you know (or don’t)
    1. If you use plenty of sunscreen, you can stay in the sun as long as you'd like.
    A. True
    B. False
  • 6. 2. Which of the following surfaces reflects
    ultraviolet rays?
    A. Snow
    B. Sand
    C. Ice
    D. Water
    E. All of the above
  • 7. 3. You don't need to protect or cover your skin
    on cloudy days.
    True
    False
  • 8. 4. Wearing white during hot weather protects you from sun damage because light-colored clothing reflects light, rather than absorbing it.
    True
    False
  • 9. 5. Choose a sunscreen with a sun protection factor (SPF) of at least:
    5
    10
    15
    30
  • 10. 6. Darker lenses on sunglasses offer better protection from ultraviolet rays than do lighter sunglass lenses.
    True
    False
  • 11. 7. Sunbathing or sun tanning once in a while won't hurt your skin.
    True
    False
  • 12. 8. The darker your skin color, the less you need to worry about sun protection.
    True
    False
  • 13. Physics
    Sunlight
    Total spectrum of the Electromagnetic Radiation given off by the sun
    Electromagnetic Radiation
    The full range of wavelengths that makeup light (visible and non-visible)
    Light waves are fluctuations of electric and magnetic fields
  • 14. Electromagnetic Spectrum
  • 15. Ultraviolet Rays
    Band of sun rays
    5% of sunlight that reaches the earth
    Reflects off of water, snow, sand and ice
    Three types
    UVA
    UVB
    UVC
  • 16. UVA
    90% reaches the earth on a cloudy day
    Not blocked by window glass
    Penetrates light clothing
    Penetrates deeper into the skin
    Has more long-term effects than UVB
  • 17. UVB
    “B” for burn
    Cloud cover provides some protection
    Intensity varies
    Time of day
    Season
    Altitude
    Weather
  • 18. UVC
    Most rays are absorbed by the earth’s atmosphere
    More dangerous than UVA and UVB
    Causes serious damage to DNA
  • 19. How does Ultraviolet Radiation affect the skin?
    Sunburns -- the most common and acute response
    Photoaging – the leading cause of skin aging; damage begins as early as in one’s 20’s
    Cancer – ultraviolet radiation is a known carcinogen (cancer causing agent)
    The effect is cumulative; the more time spent unprotected in the sun over your lifetime, the greater the risks.
  • 20. Melanin
    Skin’s protective sun filter
    Natural pigment
    Acts as a shield against the sun’s ultraviolet rays
    Greater in populations that live in area with greater sun intensity (Africa, Latin America, India)
  • 21. Skin type
  • 22.
  • 23.
  • 24. Skin Cancer
    The most common form of cancer in the US
    1 million new cases are diagnosed yearly
    1 in 5 Americans and 1 in 3 Caucasians will develop skin cancer in their lifetime
    >90% of all skin cancers are caused by sun exposure
    The risk for skin cancer doubles if a person has had 5 or more sunburns
  • 25. Tanning Beds
    Newer high pressure sun lamps can emit UVR in doses 15 times that of the sun
    Occasional use of tanning beds almost triples the chance of developing melanoma – the deadliest form of skin cancer; the use of tanning beds before the age of 35 increases the risk for melanoma by 75%
    People who use tanning beds are 2.5 times more likely to develop squamous cell cancer and 1.5 times more likely to develop basal cell cancer
    On an average day, more than 1 million people in the US tan in tanning salons; 70% are Caucasian women ages 16-49.
  • 26. Who is at risk?
    Everyone
  • 27. EVERYONe
  • 28. SPF -- Sun Protection Factor
    A rating system developed by the FDA to describe the level of sun protection provided by a sunscreen
    For example: an SPF of 30 allows an individual to stay out in the sun 30 times as long as without the sunscreen before developing the same reddening of the skin.
  • 29. Sunscreen
    SPF 15 blocks approximately 93 percent of all incoming ultraviolet rays
    SPF 30 blocks 97 percent
    SPF 50 blocks 99 percent
    AAD and the Skin Cancer Foundation recommend a minimum SPF of 15
    Reapply every 2 hours (even on cloudy days), especially after swimming or sweating
  • 30. Sunscreen Recommendations
    Broad spectrum providing protection from
    UVA
    UVB
    Apply 30 minutes before sun exposure
    Reapply every 2 hours
    Reapply immediately after swimming, toweling off or excess sweating
    Use 1 ounce each time
  • 31. Sunscreens
    Physical
    Made of zinc oxide and titanium dioxide
    Protect against UVA and UVB
    Prevent rays from being absorbed
    Chemical
    Mexoryl protects against UVA and UVB
    Avobenzoneor Oxybenzone protect against UVA OR UVB
    Absorb rays before they can do damage
  • 32.
  • 33. Sunscreens
    Cream formulations
    Contribute to destruction of coral reefs due to chemicals
    Mineral based sun protection (Colorescience® Sunforgettable) do not have chemicals that affect the environment
  • 34. Skin Cancer Foundation Recommends
    Window film
    Sunscreens with UVA and UVB protection
    Sunglasses with UVA and UVB protection
    Self tanners
    Sun protective clothing and fabric
    Makeup, lip balm and moisturizers with a sunscreen
