Time changes can affect people's routines and metaphorical internal clock that regulates when they start feeling tired. This past weekend, clocks jumped back one hour, giving some an extra hour of sleep.

That extra hour was likely needed, Dr. Jeffrey McGovern said, "The average amount of time about 35% of people based on one study found people were sleeping about six, six and a half hours and we should be getting at least seven hours of sleep per night."

Dr. McGovern is the director of the sleep lab at Saint Vincent Hospital. He says the time change can affect people differently, but the keys to maintaining routine are general good sleep hygiene practices.

"The way you fix it is really paying attention to your sleep and almost babying yourself where maybe you'll take an extra 20 to 30 minute nap, or maybe you'll be more attentive to nutrition, or maybe you'll be more attentive to exercise," he said, "These are all good sleep hygiene habits that could be very helpful."

Another tip to getting better sleep is making the bedroom a place centered around sleeping. "I like to say the bedroom should really be king over everything else. Leave all the stressors behind, the things that had to be done tomorrow or the next day will be done. Right now, it's time to concentrate on your sleep and you'll be much better off," Dr. McGovern said.
