Sunscreen for all seasons Everyday, no matter how careful we are, we are exposed to sunlight. And yes that applies to the colder months as well. Although UV radiation levels are highest under cloudless skies, they can also be high even with cloud cover.1 UV radiation levels are also influenced by ground reflection.1 Grass, soil and water reflect nearly 10% of UV radiation; fresh snow reflects as much as 80%; dry beach sand about 15% and sea foam about 25%.1 So no matter what the weather, the season or the outdoor condition, exposure to sunlight of any kind, requires us to be vigilant with our sunscreen. We know that sun exposure can lead to sunburn, the development of premature ageing and wrinkling; and can lead to skin cancers. We also know that sun damage is cumulative, which means every little bit adds up over time. The damage that leads to adult skin cancers starts in childhood and teenage years, with 80% of all sun exposure occurring before we are 18 years old.2 It is vital that children and teens are protected just as we would protect ourselves. To best protect your skin from sun damage it is essential to wear sunscreen everyday. It is important to use a high quality SPF 30+ broad spectrum sunscreen in conjunction with protective clothing, hats and eyewear, and avoid prolonged exposure to the sun. Think of sunscreen application as a marathon instead of a sprint. Apply all of your sunscreen in the morning and you’ll most likely be burnt before the day is out. Apply in the morning, and then reapply every two hours spent outside or more often if you’ve spent time in the water or have been sweating, and you’ll be safely home. Even if you don’t do anything other then sit in the sun, you still need to apply sunscreen all over again every two hours. Sure it sounds like a lot of work, but it sure beats finishing up the day burnt. 1. WHO fact sheet N°271. Ultraviolet radiation: global solar UV index. August 2002. 2.
