Clocks fall back at the end of Daylight Saving Time

By Brock Ormond

BELLEVILLE – It’s that time of year again – the end of Daylight Saving Time, that is.

That means that as of 2 a.m. this Sunday, people across North America can set their clocks back an hour, earning them one extra precious hour of sleep.

Queen’s University sleep expert Dr. Judith Davidson says that, despite the extra hour of sleep, the fall-back can affect sleep cycles and circadian rhythms in most people. However, she also says the clocks moving back isn’t nearly as problematic as the clocks moving forward in the spring.

Davidson is the author of Sink Into Sleep: A Step-by-Step Workbook for Insomnia.
