Drs. Imre Janszky of the Karolinska Institute in Stockholm published their findings this week in the New England Journal of Medicine. According to Janszky, on the Monday following the end of Daylight Savings there are 5% fewer heart attacks on average. The opposite is true for the Daylight Savings adjustment in Spring, where the risk of heart attack goes up 5% when the clocks are moved forward.

"Some people find it quite difficult to adjust to it, and the sleep quality and sleep duration is affected and it takes a certain toll," Janszky told the AFP. "There is a growing body of evidence that problems of disruptions of the biological rhythms and sleep problems are connected to cardiovascular health."

Simply moving clocks ahead or back an hour doesn't change when the sun rises, yet we are suddenly expected to change our sleeping patterns and go to work earlier or later.

"This makes this shift more dangerous to some people," Janszky said.

More than 1.5 billion people deal with a form of Daylight Savings worldwide.
