This is the weekend we lose an hour of sleep by changing our clocks.

The Monday and Tuesday after are the worst. The opposite is apparently true when falling back in October, according to cardiovascular researchers at the University of Alabama at Birmingham.

Exactly why this happens is not known but there are a few theories.

People who are sleep deprived weigh more and are at an increased risk of developing diabetes or heart disease. Sleep deprivation also can alter other body processes including inflammatory response which can contribute to a heart attack.
