During summer we limit exposure to UV rays, avoid the hours between midday and 4pm, dig out our wide-brimmed hats and keep our sunscreens close to hand. However, a winter sun poses just as much danger! During winter the sun's rays hit the earth at a lower angle, but that doesn't mean they won't harm our skin. So even if you're giving winter sports a miss and sticking to your 9 - 5, it's nonetheless vital that you protect yourself. The problem is overcast days can make us forget that, behind the clouds, the sun's still got his hat on!
And, depending on cloud cover, up to 80% of UV rays can still penetrate gloomy skies. To make matters worse, if UV rays hit snowy landscapes we're in even deeper trouble! Our bodies are suddenly bombarded not only by UV rays that pass through clouds, but also ones reflected off the ground.
