Skin cancer is the most common type of cancer in Canada. Ultra violet rays from the sun can damage anyone’s skin over time and we all have to be careful when heading out into the sun regardless of the season. The UV Index provides us with information about the strength of the sun’s ultraviolet (UV) rays. The UV Index predicts the sun’s intensity on a scale that ranges from 0 (low intensity) to 11+ (high intensity). The higher the number, the stronger the sun’s rays. Ultra violet rays from the sun can cause skin cancer and can damage skin over time but skin cancer can be prevented.
Try to stay out of the sun between 11 am and 4 pm when the sun’s rays are most intense. Look for a shady spot under a tree or under a sun umbrellaWear sunglasses with both UVA and UVB protectionUse a sunscreen that is at least SPF 15 or higher. SPF means Sun Protection Factor. The sunscreen should also say "broad-spectrum" on the label, to screen out most of the UVA and UVB rays.Put on your sunscreen 20 minutes before going outside and reapply often.Don’t forget to put sunscreen on your lips, ears and nose – these parts burn easily!Wear a wide brimmed hatPut on more sunscreen after swimming or sweating
Below are some sun safety tips to help you practice sun safety in all seasons:
