Daylight Savings Time occurred early Sunday morning as clocks sprung forward, eliminating an hour of rest. Linda Golik, from Bellin Health, says that newer research suggests it could take up to two weeks to adapt to the time change. She believes that the adjustment period weighs heaviest on teenagers because they need sleep the most.

Golik says Americans are becoming increasingly sleep-deprived. In extreme cases, she says you should consult with a physician to evaluate all possible options to ensure you’re getting a good night’s rest.
