BIRMINGHAM, AL (WAFF) -
Daylight Saving Time kicks in this weekend, and folks around the country will be changing clocks in their homes and cars and trying to acclimate themselves to the change. Early in the morning hours of March 10th, we'll lose one hour as we "spring forward."

But why? What's the point?

The concept was first put into practice in Germany during World War I as a way to save electricity, and was adopted worldwide in the years following the war. The idea was that giving everyone an extra hour of daylight during summertime would result in a decrease in electricity consumption at night.

Not everyone observes the changing of the clocks. Several countries in South America, Africa and Asia ignore it, and even some American states, (Arizona, Hawaii) territories (American Samoa, Guam, Puerto Rico and the Virgin Islands) and Canadian provinces (Yukon Territory, Saskatchewan) have stopped abiding by the change.

A petition on the White House website begs the President to do away with the clock-changing business, and adopt Daylight Saving Time as permanent. 

The practice has recently been tied to some health problems. A 2012 study from the University of Alabama Birmingham linked the change to an increase in heart attacks every spring.

"The Monday and Tuesday after moving the clocks ahead one hour in March is associated with a 10 percent increase in the risk of having a heart attack," said UAB Associate Professor Martin Young, Ph.D., in the Division of Cardiovascular Disease. "The opposite is true when falling back in October. This risk decreases by about 10 percent."
