The clocks change this weekend as we ‘spring forward’ into daylight saving time.
On the one hand, this time switch does mean we’re getting close to spring… but it also means we lose one hour of sleep this weekend.
The change back to daylight saving will happen at 2 a.m. on Sunday morning when the clocks will spring forward one hour.
Not all Canadians will be changing the clocks this weekend, though, as Yukon, most of Saskatchewan, and parts of Quebec, Ontario, and B.C. don’t adhere to daylight saving time.
And there could be good reason to ditch the switch—studies have shown the beginning of daylight saving time can negatively interfere with sleep regulation.
A 2019 report in the Journal of Clinical Sleep Medicine found there’s an increased risk of heart attacks in the weeks following the spring and fall time changes.
And a 2016 report from Finland suggested stroke-related hospitalizations increased for two days after the switch.
