In a recent study, researchers from the University of Auckland found that standing up straight not only improves self-esteem and mood in healthy people, but can also reduce the symptoms of people with mild-to-moderate depression. The study suggests that being in an upright position can make you feel more alert and enthusiastic while feeling less fearful. Give a little attention to your body language, it could improve your mental well-being.
