It happens every spring and every time it happens people complain about the one less hour of sleep they'll be getting. I don't get it. Doesn't phase me in the least, but 61% of people surveyed says it has a negative affect on them.

Even so-called experts disagree on the real effect. According to David Volpi, founder and medical director of Eos Sleep, a center for treatment of snoring and sleep apnea, it's not the big deal people make it out to be. He says, "I think people use that as an excuse. It's only an hour. It's not like you are dealing with jet lag."

On the other hand, according to sleep educator Nancy Rothstein, the one hour change is pretty significant. She says, "Our body clock is a natural thing. Changing the clock is not natural. It's a man-made thing that forces changes on us."

Regardless of what the experts say, expect any "zombies" walking around in the office today with a dazed look on their faces to use the time change as an excuse. Like everything else, this too shall pass.
