Don’t forget your hat and sunscreen!
As we finally enjoy some nicer weather in Atlantic Canada, you may be starting to spend more time outside, whether doing yard work, going for a walk or hike or just spending some time on a patio.
Sun safety is important yearround, but we’re at that time of the year again where it’s good to highlight the importance of sun safety.
Some ultraviolet radiation emitted by the sun is blocked and absorbed by the stratospheric ozone layer in our atmosphere, including UVC and some UVB rays.
But UVA and some UVB rays make it to the Earth’s surface, leading to sunburns, skin aging, cataracts and skin cancer.
The UV index measures this radiation using a numbered scale developed to help people protect themselves from the sun’s damaging rays and take necessary precautions to remain sun safe.
The UV index ranges from zero to 11-plus, with zero to two considered low, three to five considered moderate, six to seven considered high, eight to 10 considered very high and 11-plus considered extreme.
Protection is required when the UV index is three or higher. That typically occurs between 11 a.m. and 3 p.m. during much of spring and summer when it’s not uncommon to have a high or very high UV index.
And just because it is cloudy does not mean you are protected from UV rays.
So, what’s the best way to stay sun safe? First, check the UV index for the day and plan accordingly.
Use broad-spectrum and water-resistant sunscreen with a sun protection factor, known as SPF, of at least 30. Be sure to seek shade on bright sunny days and consider wearing clothing to help cover exposed skin. Sunglasses and a widebrimmed hat will also help protect your face and eyes.
Soak up the sunshine but do so safely.
