American Academy of Sleep Medicine opposes permanent daylight saving time. In March, the Senate passed the Sunshine Protection Act (S 623), which would establish permanent daylight saving time in the United States as of November 2023. While the American Academy of Sleep Medicine (AASM) agrees that clocks should not change twice a year in the fall and spring, the academy supports maintaining a national, fixed, year-round standard time (the period between fall and spring) instead of daylight saving time (the period between spring and fall when clocks are set one hour ahead). In a position statement in the October 15, 2020, Journal of Clinical Sleep Medicine, the AASM says standard time "aligns best with human circadian biology and [thereby] provides distinct benefits for public health and safety." Transitions both into and out of daylight saving time, according to the AASM, have been associated with "increased cardiovascular disease risk, metabolic syndrome, and other health risks," including sleep disruption, mood disturbances, and suicide. The bill is now awaiting consideration in the House of Representatives.
