Getting a good night's rest is essential for your health: According to the Center for Disease Control and Prevention (CDC), insufficient sleep is associated with chronic diseases including diabetes, heart disease, obesity and even depression.
"You can do just as much harm, if not more, by sleeping poorly than eating poorly or not exercising," Dr. Paul Doghramji, a family practice physician in Pennsylvania, told TODAY.
But what can you do if you wake up during the night, and can't seem to go back to sleep?
First off, know that you're not alone: About 10 percent of the population have chronic insomnia, meaning they've been experiencing sleep problems for over three months, according to Dr. Shelley Hershner, an assistant professor of neurology at Michigan Medicine's Sleep Disorders Center. And 30 percent of the population, she said, have some form of acute (shorter-term) insomnia.
