Regardless of the UV Index, the following sun safety measures are always encouraged:

  • Do Not Burn.

  • Avoid Sun Tanning and Tanning Beds.

  • Generously Apply Sunscreen to all exposed skin using a Sun Protection Factor (SPF) of at least 15 that provides broad-spectrum protection from both ultraviolet A (UVA) and ultraviolet B (UVB) rays. Re-apply every two hours, even on cloudy days, and after swimming or sweating.

  • Wear Protective Clothing, such as a long-sleeved shirt, pants, a wide-brimmed hat and sunglasses, where possible.

  • Seek Shade when appropriate, remembering that the sun's UV rays are strongest between 10 a.m. and 4 p.m.

  • Use Extra Caution Near Water, Snow and Sand as they reflect the damaging rays of the sun which can increase your chance of sunburn.

  • Watch for the UV Index.

  • Get Vitamin D Safely through a diet that includes vitamin supplements. Don't seek the sun.

Early detection of melanoma can save your life. Carefully examine ALL of your skin once a month. A new or changing mole should be evaluated by a dermatologist.
