Dont forget to put your clocks back one hour on Sunday, Nov. 3. Five things you may not have known about Daylight Saving Time: 1. Daylight Saving Time was made to save energy. In the U.S., daylight saving time was first used during World War I to conserve resources. The Department of Energy studied the energy savings in 2008. They found that during daylight saving time, U.S. electricity use decreased by 0.5 percent per day, which added up to 1.3 billion kilowatt-hours, enough to power about 122,000 average U.S. homes for a year. 2. Daylight Saving Time Begins in March and Ends in November. From World War II until recently, the seven month period of daylight saving time in the U.S. ran from April until mid-October. But in 2007, Congress adjusted daylight saving time to begin three weeks earlier and end one week later, a move they hoped would help save energy. 3. Not All US States and Territories Observe Daylight Saving Time. Arizona, Hawaii, American Samoa, Guam, Puerto Rico, Northern Marianas and the Virgin Islands do not move their clocks forward. 4. Daylight Saving Time Helps Prevent Traffic Injuries and Reduces Crime. The extra hour of daylight has been credited for preventing traffic injuries and reducing crime as people travel to and from school and work and complete errands during the daylight, and more people are out conducting their affairs during the daylight rather than at night, when more crime occurs, according to the U.S. Department of Transportation. 5. Time Changes Can Impact Body. Its just one hour, but the time shift and stress caused by time changes can be bad for the body. Researchers in Sweden reported in 2008 in the New England Journal of Medicine that the number of heart attacks jumps during the period immediately following time changes, and that those vulnerable to sleep deprivation should be extra careful.
