Wear sunglasses on bright days. In winter, reflection off snow can nearly double UV strength.

If you burn easily, cover up and use sunscreen.

Snow and water can reflect the sun's rays. Skiers and swimmers should take special care. Wear sunglasses or goggles, and apply sunscreen with an SPF of at least 15. Remember to protect areas that could be exposed to UV rays by the sun's reflection, including under the chin and nose.

Take precautions such as covering up and using sunscreen if you will be outside.

Stay in shade near midday when sun is strongest.

An easy way to tell how much UV exposure you are getting is to look for your shadow:

--If your shadow is taller than you are (in the early morning and late afternoon), your UV exposure is likely to be low.

--If your shadow is shorter than you are (around midday), you are being exposed to high levels of UV radiation. Seek shade and protect your skin and eyes.
