Why a sleep doctor says we should never change our clocks again
from The Decibel · host The Globe and Mail
On Sunday, most Canadians lose an hour of sleep as the clocks get turned forward to daylight time. But while most of us have gotten used to the bi-annual time change, our bodies have not. And with a growing number of experts saying the practice messes with our sleep – should Canadians stop messing with the clock? Today, psychology professor Joseph De Koninck is here. He studies sleep at the University of Ottawa, and his recent research looks at how Daylight Savings Time impacts our circadian rhythms, what we can do to minimize the health effects the change has, and why he thinks Canada should consider staying on Standard Time year-round.
