Whether you’re headed to the beach, planning a weekend at the lake, or checking out a summer fair, sun protection should be part of your daily routine, even when the sun’s hiding.
Karen Faurschou, educator with Central Plains Cancer Services, reminds people that UV rays aren’t just a summer thing.
“UV rays can be harmful all year round, even in the spring, fall and winter, especially when reflected off snow or water in Canada,” she notes. “UV levels can be high from late March to early October, so protection is needed beyond summer.”
Overcast skies? Still time for sunscreen
It might not look sunny, but those rays can still do damage.
“Up to 80% of the UV rays can penetrate clouds,” says Faurschou. “Recently we’ve had smoke-filled skies from the forest fires and just because you can’t see the sun doesn’t mean it’s not there.”
She also says to ditch the tanning oil.
“It typically amplifies UV exposure, increasing the risk of sunburn, skin aging, and skin cancer,” she adds. “It offers little to no sun protection and actually can be very harmful over time.”
Know your SPF and check the date
There are a lot of options on the shelf, but Faurschou says the most important thing is to use sunscreen properly and consistently.
“An SPF factor of 30 blocks 97% of the UVB rays. SPF 50 blocks 98%,” she explains. “Sprays are more convenient, but you can then miss spots or accidentally inhale. Lotions are more even and thorough.”
She also says to reapply often and make sure it’s not expired.
“Not all sunscreens are equal,” Faurschou continues. “Always look for the Canadian Dermatological Society logo.”
Sorry, base tans don’t actually help
If you’re heading somewhere tropical or just hoping to avoid a burn at the cabin, don’t rely on a “base tan.”
“A tan is actually a sign of skin damage,” Faurschou remarks. “It provides minimal protection, around an SPF 3 or less, and it increases the long-term risk of premature aging, skin cancer, especially melanoma, and DNA damage.”
She also advises against DIY sunscreen hacks found online.
“They don’t offer reliable or consistent UV protection,” she says. “If you prefer more natural products, look for mineral sunscreens with zinc oxide or titanium dioxide.”
Protect your skin and your style
Sunscreen is important, but it’s just one piece of the puzzle. Faurschou recommends throwing on a wide-brimmed hat, UV-blocking sunglasses (yes, the sticker matters), and long sleeves if you’re going to be in the sun for a while.
“Seek shade, especially between 10 a.m. and 4 p.m.,” she adds. “Use umbrellas or sunshades when you’re outdoors and stay hydrated.”
She notes that sun safety looks a little different depending on age; babies under six months should stay out of direct sunlight, while seniors are more vulnerable to cumulative sun damage.
The damage may not show up right away
A sunburn might fade, but the impact can linger.
“The UV rays damage the DNA in your skin cells,” Faurschou explains. “Over time this can cause mutations that lead to skin cancers.”
She encourages families to build good habits early, whether it’s for a day at the splash pad or an evening ball game.
“Check the UV index every day before heading out,” Faurschou says. “Perform regular skin checks and watch for new or changing moles. And remember, even if the burn fades, the damage can remain.”
