Canadian Analysis: Permanent Daylight Saving Harms Sleep and Mental Health

"With the push to eliminate the twice yearly clock change, Permanent Daylight Savings Time has emerged as the favorite for most states and provinces," writes longtime Slashdot reader kbahey, sharing the findings from a recent analysis published in the Canadian Medical Association Journal. Sci.News reports: "Ending the clock change solves one problem, but it creates another decision: which time should we live on year-round?" said University of British Columbia's Professor Raymond Lam, lead author of the study. "The health evidence points to standard time, largely because morning light matters for our body clocks, sleep, and mood." Professor Lam and colleagues examined the health consequences of the two possible permanent systems rather than the broader question of whether seasonal clock changes should be abolished. They concluded that the accumulated evidence favors permanent standard time, which keeps the clock more closely aligned with human circadian biology.
