  • Ultraviolet A (UVA) rays deeply penetrate skin, leading to age spots and wrinkles and play a role in skin cancer. 
  • Ultraviolet B (UVB) rays trigger an alarm signal of redness, pain and swelling and cause mutations that lead to skin cancer.
  • Sun protection factor (SPF), measures protection from UVB exposure. SPF 30 blocks about 97 percent of UVB rays. An SPF of more than 30 blocks 98 percent of UVB rays.
  • When selecting a sunscreen, look for true broad-spectrum protection, which blocks UVA and UVB rays, but does not pose potential health risks from toxic chemicals.
  • National Centers for Coastal Ocean Science has discovered that the sunscreen chemical benzophenone-2, or BP-2 is highly toxic to coral reefs. Sunscreens with titanium oxide or zinc oxide, which are natural mineral ingredients, have not been found harmful to corals.
  • U.S. News and Pharmacy Times surveyed 294 pharmacists for their preferred sunscreen brands. Neutrogena was chosen by 52 percent of the vote, followed by Coppertone at 30 percent and Hawaiian Tropic at 10 percent.
  • Sunscreen leads to vitamin D deficiency. Vitamin D, which we get from the sun, is important for immune system health. Some doctors recommend 5 minutes of daily, unprotected exposure, while others argue strongly against it.
  • Boost vitamin D levels by consuming vitamin D enriched products, eating salmon or other fatty fish, or taking a daily supplement of 600 units.
  • Apply sunscreen 15 to 30 minutes before you go outside. For lotions, use 2 to 3 tablespoons. Reapply every 2 hours and after swimming or sweating. Spray sunscreens may pose serious inhalation risks.
Make sun safety a daily habit and wear long, lose sleeves, pants, broad-rimmed hats and stay in the shade. Good sunglasses protect eyes from UV radiation that causes cataracts. While in the water, UV protective clothing like a long-sleeved shirt or rash guard will help prevent sunburn.
