So long sunshine.

OK, so that may be a little extreme but it can feel like that when we move from daylight saving time to standard time, pushing more light into the morning and away from the afternoon.

Daylight saving time ends Sunday Nov. 5, and we “fall back” by moving the clocks back one hour. At 2 a.m. on Nov. 5, most modern clocks automatically change back an hour (or will be set back before bed on the 4th for us old-fashioned folks.)

Daylight saving time will remain in place until 2 a.m. on Sunday, March 10, 2024 and then end again at 2 a.m. on Sunday, Nov. 3, 2024.

The idea of changing time was first instituted in the U.S. during World War I in an effort to conserve energy. It was brought back during World War II and then became law in 1966 when President Lyndon Johnson signed the Uniform Time Act, establishing the start and end times within standard time zones. The policy, regulated by the Department of Transportation, aims to save energy, reduce traffic fatalities, and reduce crime.

In 1973, President Richard Nixon signed into law the Emergency Daylight Saving Time Energy Conservation Act that made DST permanent in the U.S. In 2005, the Uniform Time Act tweaked that schedule by setting the start of daylight saving time to the second Sunday of March and the end on the first Sunday of November, lengthening the duration of DST.

Is the time change bad for your health?

Experts point to the twice-yearly clock change as a potential disruption to sleep patterns.

Dr. Phyllis Zee, a sleep researcher at Northwestern Medicine in Chicago, told the AP that while the ending of DST is easier on the body than beginning, chronic sleep deprivation can increase levels of stress hormones that raise heart rate and blood pressure, among other issues.

Sleep issues can also affect people’s ability to multitask, stay alert or even keep their balance.
