Although Justin claims his large family was not intentional, it appears it is a trait that runs in the Chambers’ lineage, or at least his parental family. He grew up in a family of seven, with two older sisters; Mia and Susan, an older brother John Jr., and a twin brother Jason.
His parents, who named him Justin Willman Chambers, are Pamela Sue Chambers and John William Eugene Chambers II. Both of them were active members of law enforcement. They served as Deputy Sheriffs in Springfield, Ohio, where they raised the actor. Through his parents, Justin has English, Irish, and German ethnic roots.
His European heritage is not the only thing he got from his parents. He also has a biological sleep deprivation disorder. The condition once caused him to check into the Resnick Neuro-Psychiatric Hospital at UCLA in January 2008. He had only managed two hours of sleep each week prior to checking in for exhaustion. To manage the condition, the actor follows a healthy lifestyle and practices hot yoga.
