Now that we’ve entered the winter holiday season, you might think it’s an odd time to talk about sunscreen. Most of us are mindful in the heat of summer to slather on sunscreen at the pool or beach, since the sun “feels” so strong.
Even with shorter days and dropping temperatures, the sun is still a powerful source of skin-damaging UV rays. And when there’s snow and ice all around, the reflection of these shiny, white surfaces strengthens the impact of the sun’s rays on our skin.
Remember to apply sunscreen to your face and hands during the cold and snowy months. An SPF of 15 is sufficient, and studies show you don’t get extra benefits from higher (and costlier) SPF numbers.
While your skin is protected, blocking the UV rays can interfere with Vitamin D production in your skin. That’s the primary source of the body’s vitamin D, since there are very few foods naturally rich in this vitamin. To make sure you get your daily requirement of vitamin D (400-800 IU), include low and non-fat dairy products (fortified) and fatty fish (naturally rich) as dietary sources. A daily supplement might be required, but check with your doctor first; only a blood test can determine the adequacy of your own Vitamin D level.
The bottom line? Sunscreen – it’s not just for summer anymore!
