Hitting the Beach? Soak Up These Top Sun Safety Tips

Do I Really Need To Use A Sunscreen?

Yes, absolutely! More than 3.5 million skin cancers are diagnosed annually. Many of these skin cancers could have been prevented with protection from the sun’s rays. The American Academy of Dermatology recommends the use of a sunscreen that offers the following:
  • Broad-spectrum protection (protects against both UVA and UVB rays)
  • Sun Protection Factor (SPF) 30 or greater
  • Water resistance for up to either 40 or 80 minutes

Does Everyone Need to Avoid Getting a Sunburn?

Again, yes! Everyone should avoid getting a sunburn. Ultraviolet radiation from the sun is associated with early skin aging, an increased risk for skin cancer, and eye damage. People who are at most risk for a sunburn are those who are fair-skinned, babies and small children, but even dark-skinned people are at risk of skin cancer.

A severe sunburn at a young age can increase the risk for getting cancer as an adult.

How Should I Protect My Baby From The Sun?

Sunscreen should only be used in children over the age of 6 months; keep younger babies out of the sun. Apply a sunscreen of at least SPF 30 and follow dosing directions. Test your baby's sensitivity to sunscreen by first trying a small amount on the inner wrist. Dress infants in lightweight long pants, long-sleeves, and brimmed hats that shade the neck.

Be sure babies stay well hydrated, too. If your baby is fussy, crying excessively, or has redness on any exposed skin area they should be moved indoors.

What Is a Broad Spectrum Sunscreen?

It is important to protect yourself from both ultraviolet A (UVA) and ultraviolet B (UVB) sun radiation. Skin cancer and early skin aging is primarily the result of UVA radiation. Sunburn is primarily caused by UVB radiation. Sunscreen products that pass the broad spectrum test as determined by the FDA and protect against both UVA and UVB rays are allowed to be labeled as "broad spectrum."

Choose a broad spectrum sunscreen that has a sun protection factor (SPF) of 30 or higher, as recommended by the American Academy of Dermatology.

What's The Best Way To Prevent A Sunburn?

The best way to prevent overall skin damage is by limiting your time in the sun, especially between the hours of 10 AM and 2 PM. Wear long-sleeved shirts, pants, sunglasses, and broad-brimmed hats to cover up your skin. Also, generously apply a sunscreen that is labeled "broad spectrum" (UVA/UVB) with a SPF value of 30 to 50 that is water-resistant.

If you aren't covering up, be sure to generously reapply sunscreen at least every 2 hours, even if it's cloudy; apply more often if you’re working up a sweat or swimming.

Does A Higher SPF Sunscreen Protect Your Skin Better?

The sun protection factor (SPF) value indicates the sunscreen level of sunburn protection. SPF values only apply to a sunscreen's UVB protection, not UVA. Higher SPF values (up to 50) provide greater sunburn protection. A sunscreen with SPF 50 blocks an estimated 98 percent of UVB rays; the added increase in UVB protection is minimal for sunscreens over SPF 50.

SPF numbers like 100 or 150 can give people a false sense of security and entice them to stay in the sun longer without added protection.

Should I Use A Sunscreen Every Day?

The American Academy of Dermatology suggests that you use sunscreen every day that you will be outside. The sun emits harmful UV rays year round. Even on cloudy days, up to 80% of the sun’s harmful UV rays can penetrate your skin. Snow, sand, and water increase your need for sunscreen because they reflect the sun’s rays.

Apply a generous amount, up to one ounce, or "enough to fill a shotglass." You may need more depending upon your body size. Apply the sunscreen to dry skin 15 minutes before going outdoors.

Are Sunscreens Safe?

Sunscreen products are regulated as over-the-counter (OTC) drugs by the U.S. Food and Drug Administration (FDA). The FDA has several safety and effectiveness regulations in place that govern all sunscreen products.

Using sunscreen, seeking shade and wearing protective clothing are all important behaviors to reduce your risk of skin cancer. Preventing sunburn and skin cancer outweigh any unproven claims of toxicity or human health hazard from ingredients in sunscreens.

What Should I Know About Spray Sunscreens?

The FDA is looking into the risks of spray sunscreens and the fumes they produce. To avoid the fumes, never spray sunscreen around or near the face or mouth. It is best to use spray sunscreens in well-ventilated areas. Use caution with spray sunscreens around ignition sources like grills or lighters; they may be flammable.

Spraying sunscreen can increase the chance you will miss an area that may burn, especially if it's windy. Spray the sunscreen into your hands and then generously apply the sunscreen directly to your skin, trying not to miss any spots.

What Is The UV Index?

The ultraviolet (UV) index was developed by the National Weather Service to predict the daily risk of sunburn in local areas based upon predicted weather conditions. You might see this reported in the daily weather forecast.

The UV index typically falls between zero and 11+, where zero to two indicates a very low risk of sun exposure; 10 indicates a very high risk of exposure; and 11+ is an extreme risk of unprotected sun exposure. These numbers can help you to predict your level of local sunburn risk and need for additional sun protection.

Will Using Sunscreen Limit My Vitamin D Absorption?

Vitamin D comes from sun exposure, food, or supplements. However, according to the American Academy of Dermatology, using sunscreen may decrease your skin’s production of vitamin D. If you are concerned that you are not getting enough vitamin D, discuss this with your doctor who can measure your levels.

Food such as certain kinds of fish (salmon, tuna), eggs, fortified milk and yogurt contain vitamin D. Some fish such as tuna may be high in mercury, so watch your consumption. If you choose a vitamin D supplement, be sure to choose one that contains vitamin D3 (cholecalciferol).
