The American Academy of Sleep Medicine (AASM), a professional organization of doctors that controls the accreditation of U.S. sleep clinics, has officially called for the elimination of daylight saving time. 

“An abundance of accumulated evidence indicates that the acute transition from standard time to daylight saving time incurs significant public health and safety risks, including increased risk of adverse cardiovascular events, mood disorders, and motor vehicle crashes,” AASM said in a position paper that will be published in the Journal of Clinical Sleep Medicine on October 15.
