The Impact of Daylight Saving Time on Health and Society

Daylight saving time is ending on the first Sunday in November, with clocks falling back an hour at 2 a.m. in most of North America, Europe, Australia, and New Zealand. Some U.S. states, such as Hawaii and most of Arizona, do not participate in the time change. The concept of daylight saving time was proposed by Benjamin Franklin in 1784, but it was implemented in the United States in 1918 to address train transportation coordination concerns during World War I. While there have been efforts to eliminate the semiannual tradition, there is currently no major movement to end daylight saving time in the U.S.
