More impressively, expansive postures also altered the participants’ hormone levels. Using salivary samples, Carney and colleagues found that expansive postures led individuals to experience elevated testosterone (T) and decreased cortisol (C). This neuroendocrine profile of High T and Low C has been consistently linked to such outcomes as disease resistance and leadership abilities. Although past research has found that occupying a powerful role leads to expansive postures, Carney et al.’s paper is the first to investigate the reciprocal relationship – the causal effect of posture on the mental experience of power.
We talk a lot about hormones and the importance of minimising chronically high cortisol. The implication of this is that you can consciously have an impact on limiting this hormone simply by adopting a more confident posture. Make yourself bigger, more cocky looking.....and you will be even on an hormonal level.
Interesting stuff - expansive, confident posture has impacts on your behaviour and your hormonal state. This is body/mind stuff again and also ties in to the piece on Posture and Attractiveness that I highlighted last month.
