The Message Doesn’t Get Old, but Our Skin Does

We love the sun, especially after a dreary winter and rainy spring. Whether working or playing outdoors, attending parties and picnics, enjoying trips to the beach, or just hanging on the deck or in the yard, we soak up those rays, get our vitamin D, and savor our 2017 tans. But this year, as the perennial warnings about sun exposure and the dangers of Ultraviolet (UV) rays hit the air waves, take note: Skin cancer is the most common form of cancer in the United States, and you can help minimize exposure and prevent its onset by taking simple precautions.

Unprotected exposure to UV radiation is the most preventable risk factor for skin cancer. In fact, UV radiation from the sun and tanning beds is classified as a human carcinogen by the U.S. Department of Health and Human Services and the World Health Organization. Each year, more new cases of skin cancer are diagnosed in the U.S. than new cases of breast, prostate, lung, and colon cancer combined. One in five Americans will develop skin cancer in their lifetime, and one American dies from skin cancer every hour.

Chronic exposure to the sun suppresses our natural immune system and also causes premature aging, which over time can make the skin become thick, wrinkled and leathery. Since it occurs gradually, often manifesting itself many years after the majority of a person’s sun exposure, premature aging is often regarded as an unavoidable, normal part of growing older. However, up to 90% of the visible skin changes commonly attributed to aging are caused by the sun. With proper protection from UV radiation, many forms of skin cancer and most premature aging of the skin can be avoided.

Properly protecting ourselves from UV exposure

The best way to lower our risk of skin cancer is to protect our skin from the sun and ultraviolet light. Using sunscreen and avoiding the sun helps reduce the chance of many aging skin changes, including some skin cancers. However, it is important not to rely too much on sunscreen alone. You should also not use sunscreen as an excuse to increase the amount of time you spend in the sun. Even with the use of sunscreen, people should not stay out too long during peak sunlight hours; UV rays can still penetrate our clothes and skin and do harm.

When possible, avoid sun exposure during the peak hours of 10:00 am to 4:00 pm, when UV rays are the strongest. Clouds and haze do not protect you from the sun, so use sun protection even on cloudy days.

Use sunscreens that block out both UVA and UVB radiation. Products that contain either zinc oxide or titanium oxide offer the best protection. Less expensive products that have the same ingredients work as well as expensive ones. Older children and adults (even those with darker skin) benefit from using SPFs (sun protection factor) of 15 and over. Many experts recommend that most people use SPF 30 or higher on the face and 15 or higher on the body, and people who burn easily or have risk factors for skin cancer should use SPF 50+.

Here’s how to use sunscreen to ensure the best possible protection from the sun’s damaging UV rays:

  • Adults and children should wear sunscreen every day, even if they go outdoors for only a short time.
  • Apply 30 minutes before going outdoors for best results. This allows time for the sunscreen to be absorbed.
  • Remember to use sunscreen during the winter when snow and sun are both present.
  • Reapply at least every two hours while you are out in the sunlight.
  • Reapply after swimming or sweating. Waterproof formulas last for about 40 minutes in the water, and water-resistant formulas last half as long.
  • Adults and children should wear hats with wide brims to shield from the sun’s rays.
  • Wear protective clothing. Look for loose-fitting, unbleached, tightly woven fabrics. The tighter the weave, the more protective the garment.
  • Avoid sun lamps, tanning beds, and tanning salons.
  • Buy clothing and swimwear that block out UV rays. This clothing is rated using SPF (as used with sunscreen) or a system called the ultraviolet protection factor (UPF) index.
  • Avoid surfaces that reflect light, such as water, sand, concrete, snow, and white-painted areas.
  • Beware that at higher altitudes we burn more quickly.

The sun’s rays are important to our health, in moderation, but we get more than enough just by being outdoors for normal activities like going to work and to school, and when puttering in the yard or walking the dog. Taking simple, painless steps to help protect ourselves and our children now can make a huge difference later in life.
