Finding it difficult to get up after the switch to daylight-saving time this weekend? You also may be at increased risk for a heart attack, a heart expert claims.

"The Monday and Tuesday after moving the clocks ahead ... is associated with a 10 percent increase in the risk of having a heart attack," Martin Young, an associate professor in the cardiovascular disease division at the University of Alabama at Birmingham, said in a university news release. "The opposite is true when falling back in October. This risk decreases by about 10 percent. "Exactly why this happens is not known but there are several theories," Young said. "Sleep deprivation, the body's circadian clock and immune responses all can come into play when considering reasons that changing the time by an hour can be detrimental to someone's health."

Here are som tips for adapting to the time change:

•Eat a healthy breakfast.
•Head outside to catch some sunlight in the early morning.
•Spend a few minutes getting some morning exercise, as long as you don't have heart disease.
