Daylight saving time: Fact and fiction
The Germans were the first to officially adopt the light-extending system in 1915 as a fuel-saving measure during World War I. These included strokes, heart attacks, accidents and changes in mood, for example, said Dr. Jennifer Ashton, ABC News' chief medical correspondent. Ticking away at the molecular level, the biological clock is entrained -- or set -- by exposure to sunlight and darkness. It regulates bodily functions such as metabolism, blood pressure and hormones that promote sleep and alertness.
The fight over daylight saving time has been going on for more than 100 years now. Should we turn the clocks forward in the spring and set them back in the fall? If not, then should we either stick with daylight saving time or the more traditional standard time?, Montana, Minnesota and the Dakotas have all considered similar measures in recent years without any real momentum. Proposals often lose traction because Congress would have to revise the Uniform Time Act to make any changes possible.
