BIRMINGHAM, Ala., Oct. 20 (UPI) -- Beating the blues is important to one's mental health because it is a form of depression, a U.S. expert suggests.
"I think depression is a spectrum, and full-on depression is when you experience things like impaired appetite, disrupted sleep, lack of concentration and ruminative thoughts," Diane Tucker, a professor of psychology at the University of Alabama at Birmingham, said in a statement. "Feelings of discouragement or the blues are on that continuum, and I think it is important to be attentive to those feelings."
