At 2 a.m. Sunday, we will be going back to Standard Time and moving the clock back one hour. Sleep medicine professionals say that an extra hour of sleep this weekend will help most wake up rested but that change in "light" could affect some people's sleep patterns. Doctors say you should practice good sleep hygiene.

Some studies say that regularly disrupted sleep can cause more cardiovascular events, motor vehicle accidents, and psychological problems. But making some slight adjustments before you lose an hour this Sunday could help you rest better.
