Chiropractors know that mom was right all along when she told us to "stand up straight." But now there's empirical evidence to give even more weight to her command. Good posture is essential to mental as well as physical health, keeping bones and joints aligned while boosting confidence. In fact, posture has been shown to have a greater influence on a person's feelings of power than his or her job title or position.
In a 2012 Harvard study, participants who spent a few minutes in private "power posing" performed better in high-stakes mock meetings and interviews. Slouching one's shoulders, not surprisingly, may have the opposite effect, lowering self-esteem.
