WASHINGTON – Daylight saving time may have a greater influence on your life than you realize, leaving you more tired and hungrier.

Dr. John Sharp, a psychiatrist and neuropsychiatrist at Beth-Israel Deaconess Medical Center in Boston, tells Fox News the time change essentially adds up to being a “fast-forward into winter.”

He says moving the clock back an hour this weekend gives people a sense of jet lag. It can take two to three weeks to adjust, says the leading Harvard psychiatrist and author of The Emotional Calendar.

His advice: Prep your to-do list well ahead of time. He says it will take more effort and determination to complete those every-day errands.

Sharp also says in about a week you may find you have a bigger appetite. He says you need to stick to your eating schedule and maintain your healthy habits.

To help with the adjustment, extra caffeine during the day is acceptable. And for those having trouble catching ZZZs, melatonin may help.

Daylight saving time ended at 2 a.m. Sunday. If you haven’t already, turn your clocks back an hour.
