An updated position statement from the American Academy of Sleep Medicine supports the replacement of daylight saving time with permanent standard time.

The statement is published in the Journal of Clinical Sleep Medicine.

It is the position of the AASM that the United States should eliminate seasonal time changes in favor of permanent standard time, which aligns best with human circadian biology. According to the statement, evidence supports the distinct benefits of standard time for health and safety, while also underscoring the potential harms that result from seasonal time changes to and from daylight saving time.

"By causing the human body clock to be misaligned with the natural environment, daylight saving time increases risks to our , mental well-being, and ," said lead author Dr. M. Adeel Rishi, who is chair of the AASM Public Safety Committee and a pulmonary, , and critical care specialist at Indiana University Health in Indianapolis. "Permanent standard time is the optimal choice for health and safety."

The original position statement published by the AASM in 2020 stated that current evidence best supports the adoption of year-round standard time. Based on a growing body of evidence, the updated position statement emphasizes that daylight saving time should be replaced by permanent standard time. This position is supported by similar statements adopted by other organizations including the Society for Research on Biological Rhythms, National Sleep Foundation, Sleep Research Society, and American Medical Association.

"Permanent standard time helps synchronize the body clock with the rising and setting of the sun," said Dr. James A. Rowley, president of the AASM. "This natural synchrony is optimal for , and sleep is essential for health, mood, performance, and safety."

The was developed by the AASM Public Safety Committee and based on a review of existing literature. It was approved by the AASM board of directors and endorsed by 20 medical, scientific, and advocacy organizations:

  • American Academy of Cardiovascular Sleep Medicine
  • American Academy of Dental Sleep Medicine
