Daylight savings time has been around since about World War I when Germany instituted it, and it was soon followed by other European countries and the United States.
However Daylight Saving time – despite the fact we changed clocks last weekend – may soon be going out of style. Last week the European Union suggested member countries no longer had to abide by “spring forward, fall back” after officials signaled they may drop the rule which requires it.
The “time change” has always been rather controversial, but since the Uniform Time Act in 1966 all states have been in compliance. The exceptions are Arizona and Hawaii, who opted out.
Outside of America and Europe’ other countries don’t alter the time, including most African countries.
When first passed in the United States, states were required to observe DST beginning at 2 a.m. local time on the last Sunday in April and to end it at 2 a.m. local time on the last Sunday in October. Through the years, there have been changes, and a 2007 study indicated that DST results in energy saving.
More recently daylight saving time may be falling out of favor. The American Academy of Sleep Medicine published a report this year that it may cause health issues.
“Although chronic effects of remaining in daylight saving time year-round have not been well studied, daylight saving time is less aligned with human circadian biology—which, due to the impacts of the delayed natural light/dark cycle on human activity, could result in circadian misalignment, which has been associated in some studies with increased cardiovascular disease risk, metabolic syndrome and other health risks,” according to Rishi MA, Ahmed O, Barrantes Perez JH, et al. Daylight saving time: an American Academy of Sleep Medicine position statement.
“It is, therefore, the position of the American Academy of Sleep Medicine that these seasonal time changes should be abolished in favor of a fixed, national, year-round standard time,” according to the study.
