Overexposure to UV radiation from the sun is a leading cause of dermatological diseases, including skin cancer.

Although it is sometimes impossible to avoid exposure, some of the following tips may help to minimize exposure and risk:

• Time of day
  Although sometimes impossible, try to schedule your activities before 11 a.m. or after 3 p.m. when the sun's rays are most powerful.
• Shade
  Spend your breaks in a shaded area. 
• Clothing
  Make sure your clothes cover as much of your skin as possible. Materials should be light and cool, such as cotton or lightweight synthetics. Wear a wide brimmed or legionnaire-style hat (with a back flap) - baseball caps don't protect the ears or the vulnerable neck area. 
• Sunglasses
  Don't forget sunglasses - 100 % UV protection, wraparounds are recommended. 
• Sunscreen
  Apply a broad spectrum, SPF 15 or higher sunscreen 15 to 30 minutes before going out. Reapply every two hours, especially after vigorous activity or sweating. Choose a waterproof or sweatproof sunscreen if you are in the water or will be sweating.
• Lip Balm
  Don't forget to use an SPF 15 or higher lip balm.
