Analysis supports permanent standard time as clocks stay on daylight saving

A new analysis by sleep, mental health and economics experts argues that permanent standard time is better for health than keeping daylight saving time all year. The article says Alberta, British Columbia, Manitoba and the Northwest Territories have all moved toward staying on yearround daylight time instead of changing clocks twice a year. But the researchers, including neuroscientist Ralph Mistlberger of Simon Fraser University, say darker winter mornings could disrupt sleep, affect students, and create wider health concerns. Published in the Canadian Medical Association Journal, the analysis reviewed multiple studies and concluded that standard time is more closely aligned with the body’s natural rhythm. It cites possible effects on sleep, schooling, productivity and longterm health, while also noting that public surveys in some provinces did not offer permanent standard time as an option.
