Time To Spring Ahead This Weekend for Daylight Saving Time [AUDIO]

It's that time of year again when we turn the clocks ahead an hour in the annual switch to daylight saving time.

While many of us look forward to the extra daylight during the day, the initial adjustment isn't always easy.

"For those who go to bed earlier, it's harder to fall asleep when there is still daylight outside," said Dr. Priyanka Yadav, sleep specialist at Somerset Medical Center. "Our body usually secretes melatonin when we sense darkness to help us prepare to go to sleep. So, going to sleep when the clocks go ahead is actually easier for the night owls because, chances are, it's dark when they're heading to bed."

"On the flip side, because of the later hour, it's often more difficult for the night owls to wake up the next day," said Yadav. "So, the morning after the clocks go ahead, you can expect to be sleepy. It's ok to take a nap, but limit it to 15 or 20 minutes because the longer you sleep during the day, the harder it is to fall asleep at night."

You know the clocks are going ahead this weekend, so what can you do to prepare? "Starting a few days before, you can start going to bed 15 to 20 minutes early," said Yadav. "If you have children, start their bedtime routine early, so they can make as easy a transition as possible."
