An interesting experiment was done recently where the testosterone and cortisol levels were measured in people who were in different poses. The testosterone in your body gives a feeling of ‘confidence’, whereas cortisol gives the feelings of ‘stress’.
People who were put into ‘low power’ poses, ie hunched over or curled up, had an increase of cortisol and decrease in testosterone within 2 minutes of entering that pose. People who were put into ‘high power’ poses, ie shoulders out, wide leg stance, hands on hips or out to the side, had an increase of testosterone and decrease in cortisol within 2 minutes.
This really goes to show that your posture and body language can chemically affect your mood and how you feel.
