New Report: THIS Is What We Lose Sleep Over

A good night's rest is never a given when you're a parent. But—aside from crying babies or kids wanting water or another bedtime story—what actually causes us to lose sleep? A new report from Bankrate.com did a deep dive into the question of what makes our nights restless, and came up with some answers.

According to the researchers, older millennials (those ages 28 to 37) say that money worries have cost them some serious shut-eye, making them the group that's the most concerned about their bankrolls. In fact,people who fall into this age range worry more than anyone else about credit card debt (24% have chased zzz's in vain because of this) and paying off their monthly mortgage or rent bil (17%).

For younger millennials (those 18 to 27 years old), it's work that tops the angst A-list, with 39% of them saying they've lain awake at night fretting over stuff back at the ol' office. They also lose sleep due to stress over family relationships (32%), their romantic partners (31%) and pals (24%).
