With residents in Ontario set to roll the clocks back in just over a week, the discussion has ramped up regarding if Daylight Saving Time (DST) should walk into the sunset.
If there is any choice, the Canadian Society of Chronobiology (CSC) is recommending Ontario sticks to "Standard Time" 12 months of the year.
"In a nutshell, it's because it's going to be closer to our own internal biological clock," said Patricia Lakin-Thomas, a board member with the CSC, and also a biology professor at York University.
She told The Mike Farwell Show on 570 NEWS our biological clock in the brain is set by light, and sends information to clocks around the body.
She brought up how when we travel through time zones and get jet lag, our brain clock can set rapidly but the rest of the body will be playing catch up over the next couple days, as they set a bit more slower.
"Our brain clock wants to set to the sun, and in particular, it wants to set to the sunrise," Lakin-Thomas said, "Because our brain clock runs a little bit slow. We lose about 10-30 minutes a day, and we need light in the morning to speed us up."
She points out year-round Daylight Saving Time would give us more light in the evening, pushing some people to stay up later.
And your social clock may not be a fan of that.
"You lose sleep when you push your clock late," she said, "Our social clock is going to be an hour out of step with our body clock, and we're going to feel like we're just sort of permanently jet lagged all year round."
In Ontario, Lakin-Thomas said in the middle of winter, we wouldn't have the sun rise until around 9:00 a.m. on DST.
She also pointed out the health impacts of the system we have now, particularly when the clocks go ahead an hour in the spring.
She said that's when people lose sleep, and we start seeing an increased risk of heart attacks, strokes and people are more likely to get into a collision.
