Scientific reasons to improve your body language

People perceive you as being confident, trustworthy, happy, or otherwise mostly because of how you carry yourself.  As a first impression, your body language and mannerisms matter even more than substance.

To make it more interesting, here’s what we know from science about straightening up, smiling, avoiding fidgeting, and other basic body language patterns:

1. Testosterone, a confidence-enhancing hormone for both genders, increases 20%

2. Cortisol, a stress hormone that impedes performance, decreases 25%.

Cool reasons to straighten up and act the part.
