As part of National Sun Awareness Week, Niagara Health is urging residents to take caution in the sun and reduce their exposure to ultraviolet radiation.
Skin cancer is the most common cancer in Canada, but it is also one of the most preventable. About 80,000 cases of skin cancer are diagnosed in Canada each year, more than 5,000 of which are melanoma, the mostly deadly form of skin cancer.
However, there are ways to protect yourself.
“The best way to lower the risk of developing skin cancer is to reduce your exposure to ultraviolet radiation (UVR),” says Dr. Janice Giesbrecht, Niagara Health’s Chief of Medical Oncology. “You can enjoy yourself outside as long as you protect yourself from the sun. And it’s important to protect against UV rays throughout the year, not just in the summer.”
Here are some tips from the Canadian Cancer Society to protect yourself in the sun:
• Check the UV index before going outside. When the UV index is 3 (moderate) or higher, wear protective clothing, sunglasses and sunscreen.
• Try to reduce sun exposure between 11 a.m. and 4 p.m., when the sun’s rays are strongest, or any time of the day when the UV index is 3 or more.
• If possible, plan outdoor activities before 11 a.m. or after 4 p.m. If you are concerned about sun protection before 11 a.m. or after 4 p.m., check the UV index for your city that day to see what times it is expected to be over 3.
• Ensure you are choosing a broad-spectrum (protects against UVA and UVB) sunscreen with at least an Sun Protection Factor (SPF) of 30.
• Protect your eyes by choosing sunglasses with UV 400 protection (typically labeled with a UV400 sticker).
• Be aware that exposure to UVR can occur through glass. Glass windows can filter ultraviolet B (UVB) rays, but ultraviolet A (UVA) rays can pass through ordinary untinted glass (such as a car windshield).
• Seek shade or create your own shade when outside, especially between 11 a.m. and 4 p.m. Be prepared to make your own shade by taking along an umbrella. Trees and hedges can provide excellent shade. How much shade will depend on the density and the type of plant.
• Cover your arms and legs. Wear loose-fitting and tightly woven clothing that protects exposed skin from the sun, such as long pants, long-sleeved shirts and long skirts.
