​How Staying Up Late Might Be Tanking Your Mood

If you’ve made a habit of staying up too late and sleeping in every morning, you might be at a greater risk for depression, especially if you have type-2 diabetes, according to a new study presented at the Endocrine Society’s annual meeting in Orlando.

Researchers surveyed nearly 500 people suffering from diabetes in Chicago and Thailand. They included vastly different geographic areas in the study because sleep cycles vary by location.
