Grey's Anatomy star Justin Chambers says he checked in to UCLA's psych ward recently because of a longtime sleep disorder.

"It's an issue that I've had for a while," Chambers told PEOPLE magazine in his first interview since the incident. "It's a biological sleep disorder. Your mind keeps racing, and your body is tired. It wants to go to sleep, but it can't."

At his wit's end, the 37-year-old actor, husband, and father of five says he was sleeping no more than an hour a week during the two months leading up to his hospital stay.
