Saskatchewan people tend to talk tough about braving the bitter cold, but Regina's Dave Limacher really walks the talk.
He regularly goes shirtless when he's shovelling snow at his Lakeview-area home — even when the mercury dips down as low as -10 C.
Limacher is a believer in what's called "cold thermogenesis", which holds that exercising in frigid conditions can help burn fat and bring other health benefits.
"We can use cold to burn fat. We can use cold to improve our hormone function, and just improve overall health. It's probably one of the easiest ways to do it," he said.
When it's colder than -10, Limacher wears a thin shirt to protect his skin.
Often he'll go shoeless when he's clearing away the white stuff.
He says he's sensible and doesn't stay out for prolonged periods when there are dangerous wind chills.
But he really went all out earlier this week when CBC News dropped by to watch him in action.
During his brief, shirtless demonstration, it was a bone-chilling -24.
He admits he sometimes gets looks from his neighbours.
"They say, 'You're nuts' and they kind of give me a look like, 'You're crazy'," he said.
"But I know it's good for my health and there's a lot of research to show it, so it doesn't bother me."
