>> For most Americans, it was dreaded all of last week. For other less prepared individuals, it was an unpleasant surprise Sunday morning. But like it or not, at 2 AM on March 12th, most of North America lost an hour of sleep. Daylight Savings Time is the practice of moving clock forward by one hour during summer month so that daylight last longer into the evening.

But the growing body of scientific research suggest that springing forward may do more harm than good. Study show the time change and the lack of sleep caused by it will likely prompt an increase in heart attacks and strokes, cause more car accidents, and reduce worker productivity. This video you're watching, for example, took me longer than usual to edit.

In December, a psychology journal published results showing that federal judges handed out sentences that were, on average, 5% longer the day after moving the clocks forward than those given out one week before or after. Perhaps the most disturbing thing about Daylight Savings Time is that it won't even cut the nation's energy bill contrary to what the experts once believed.

The practice was widely adopted during World War II as an energy saving measure. The rationale being that a later sunset would mean fewer hours using electricity. But studies have generally failed to show any significant energy savings associated with the shift. Abolishing the practice would require a law passed by congress.

Legislators in some states have tried unsuccessfully to pass laws to abandon the time change. The only states that don't reset the clocks twice a year are Arizona because of the heat and Hawaii because its location near the equator means changing the clocks wouldn't make daylight last much longer.

Most of Europe will have to go through the same painful time change in two weeks.
