Summer Calls for Sunscreen!

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.
