True or False: Tanning beds are safer than the sun
False. All forms of UV tanning damage the skin’s DNA, which can lead to cancer. Just one indoor tanning session can increase the risk of melanoma by 20%
True or False: You do not need to apply sunscreen on a cloudy day.
False. UVA can penetrate clouds and cause damage to the DNA in the midlayer of the skin, even if you don’t feel burnt.

c. Sand

D. Snow is the most reflective surface (88%), followed by water (75%), sand (15%), and concrete (10%).
True or False: During the winter months, tanning beds can help increase your Vitamin D production
Answer: False. Tanning beds do not produce the right wavelength of light for Vitamin D production. Instead of using a tanning bed, there are many foods that have a good supply of Vitamin D, like salmon, dairy and plant milks, and egg yolks.

a. 1 ounce
b. 3 ounces
c. 4.5 ounces

True or False: glass is effective at blocking UV radiation.
False. There are two types of UV radiation: UVA and UVB. Glass blocks UVB radiation, but not UVA radiation.
True or False: Melanoma is the most common form of cancer in adults between the ages of 25 and 29.
True. Melanoma is also the second most common type of cancer diagnosed in 15- to 19-year-olds.
What are three things you should wear while skiing or snowboarding to protect yourself from the sun?
Possible answers: Sunscreen, goggles, neck gaiter/other face covering
What does SPF stand for?
Answer: Sun Protection Factor. SPF measures a sunscreen’s ability to block UVB rays and tells you how well they prevent sunburns.
3. How often should you reapply sunscreen?
a. Every 15 minutes
b. Every 30 minutes
c. Every hour
d. Every two hours
D! You should reapply sunscreen approximately every two hours.
True or False: Getting a tan or a spray tan is an effective way to prevent sunburns.
False. While a tan does provide some SPF protection, it’s very small (approximately 2-4SPF) and is not an effective way to prevent sunburns.
True or False: If I use sunscreen and other protective measures, my skin will improve.
False. Wearing sunscreen and doing other sun safety measures can help prevent further damage, it can’t reverse the damage that’s already been done.
What skin care measure, IN ADDITION TO SUNSCREEN, can you take to protect your skin in the winter?
Answer: Moisturize!!! Cold winter weather is very drying, and your skin is healthier if it’s hydrated. Consider a moisturizer or a moisturizing sunscreen with ingredients such as glycerin or lanolin that help trap moisture.
If you have a mole, what things should you check for?
a. Symmetry
b. Shape and size
c. Color
d. All of the above
Answer: D. If you have a mole, you should check it on a regular basis and ask the following questions: • Is it asymmetrical? • Is the border irregular? • Is the color uniform? • Is it larger than the eraser of a pencil? • Does it change size or shape? , If you have a concern about a mole, you can make an appointment with your doctor to have it checked out.
True or False: 100 SPF is better then 50 SPF
False! There is little to no difference between sunscreens higher then 50 SPF
There are two types of UV radiation: UVA and UVB. Which type of UV radiation is responsible for sunburns? Which type causes skin aging?
UVB radiation is responsible for sunburns. UVA radiation causes skin aging. UVB radiation accounts for only 5% of solar radiation while UVA radiation accounts for the other 95%
What are the long-term effects of sun exposure?
Cancer, Cataracts, Aging including wrinkles, hyperpigmentation, liver spots, uneven skin texture/coloration, and spider veins (aka broken capillaries)
True or False: UV exposure is greater when you’re at a higher elevation.
True. Even though you can still get sunburned at a lower elevation, UV exposure increases the higher you are in elevation. For example, Boulder’s UV exposure is about 26% higher than it is at sea level. If you’re going skiing, apply sunscreen and wear layers to shield your skin from exposure.
True or False: Aftersun products repair the damage done by sunburn
False, No, they don’t. While aftersun products may soothe the unpleasant symptoms of sunburn, they won’t fix any damage that was done to the DNA inside your cells. So, if you start to notice the signs of burning, seek shade and cover up immediately.
True or False: Darker skinned people do not need to wear sunscreen
False! Although people with darker skin are at a lower risk for skin cancer, they should still wear sunscreen to protect from sun damage, aging and hyperpigmentation. When people of color develop melanoma, it’s usually detected later and with a worse prognosis, so wearing sunscreen is crucial.
There are two types of UV radiation: UVA and UVB. Which wavelength of UV radiation is longer?
UVA radiation is longer and penetrates deeper into the skin. UVB has a shorter wavelength and only penetrates the upper layer of skin. Tanning
