The American Academy of Sleep Medicine, the largest scientific organization that studies sleep, now wants to replace daylight saving time with a move to a year-round fixed time.
That way, our internal circadian clocks would not be misaligned for half the year. And it would eliminate the safety risk from sleep loss when transitioning to daylight saving time.
States advocating for permanent daylight saving time are typically those that rely on tourism. Environmentalists, favoring less energy consumption from morning heating and evening air conditioning, often support permanent standard time. Religious groups, whose prayer times are linked to sundown and sunrise, also tend to prefer permanent standard time. So do many educators, opposed to transporting children to school during mornings when it’s still dark.
As you ponder what system is best for a national year-round standard, consider this: The American Academy of Sleep Medicine has recommended we go with permanent standard time – a better way to align with our natural circadian clock and minimize health and safety risks.
