People are often more influenced by how they feel about you rather than by what you’re saying.
According to Harvard Business School professor Amy Cuddy, holding your body in “high-power” poses for short time periods can summon an extra surge of power (through increased testosterone) andsense of well-being (through lower levels of cortisol).
“We used to think that emotion ended on the face,” Dr. Cuddy says. “Now there is established research showing that while it’s true that facial expressions reflect how you feel, you can also ‘fake it until you make it.’ In other words, you can smile long enough (two minutes) that it makes you feel happy. This work extends that finding on facial feedback, which is decades old, by focusing on postures and measuring neuroendocrine levels.”
