Canadian researchers urge standard time over permanent daylight saving time
A University of British Columbia-led study argues that if Canada ends biannual clock changes, it should settle on permanent standard time rather than permanent daylight saving time, citing risks to sleep and mental health from darker winter mornings. The warning comes as Yukon, British Columbia, Alberta and the Northwest Territories move toward permanent daylight saving time, and as a U.S. House bill for the same policy awaits Senate action.
