1. Your posture can increase or decrease your testosterone levels.
In 2010, Amy Cuddy of Harvard University and Dana Carney and Andy Yap of Columbia University tested the effects of what they call “power posing,” and found that posture has a direct effect on testosterone levels.
In the study, test subjects had to spend two minutes sitting in either high-power or low-power poses. High-power poses were expansive and open, meaning that the subject expanded their body to take up more space and brought their limbs away from the center of their body. Subjects in low-power poses took up less space and brought their limbs in closer to the center of their body.
The study found that after just two minutes, high-power posers experienced a spike in testosterone levels, while the low-power posers experienced a drop in testosterone.
Testosterone is often thought of as the male sex hormone, but it plays a role in many important bodily functions in both men and women. In addition to regulating libido and reproductive health, testosterone promotes muscle and bone growth, stimulates the creation of red blood cells, increases the production of skin collagen, improves spatial memory and mood, and increases self-esteem and confidence.
If spending just two minutes in a posture can create a measurable shift our testosterone levels, imagine the effects of spending a lifetime in a certain posture?
