Changing between standard time and daylight savings disrupts more than just sleep.
Based on these studies and other evidence, the American Academy of Sleep Medicine’s (AASM) position statement strongly agrees that daylight saving time should be eliminated
AASM Position Statement: Abstract
Although chronic effects of remaining in daylight saving time year-round have not been well studied, daylight saving time is less aligned with human circadian biology—which, due to the impacts of the delayed natural light/dark cycle on human activity, could result in circadian misalignment, which has been associated in some studies with increased cardiovascular disease risk, metabolic syndrome and other health risks. It is, therefore, the position of the American Academy of Sleep Medicine that these seasonal time changes should be abolished in favor of a fixed, national, year-round standard time.
