New study links early bedtimes to better mental health

A new study is linking early bedtimes to better mental health among older people. The study, funded in part by Stanford University, looked at sleep habits among more than 73,000 people in the U.K. Researchers found that people who went to be early had a decreased risk of depression and anxiety. We talked with Jamie Zeitzer, a psychiatry and behavioral sciences professor at Stanford, for more insight on the findings.
