We know our minds change our bodies. But do our bodies change our minds?

Powerful people typically are assertive, confidant, optimistic, risk takers, tend to think more abstractly. Physiologically they have more testosterone (dominance hormone) and less cortisol (stress hormone). High power alpha males in nature have high testosterone and low cortisol and powerful and effective leaders also have high testosterone and low cortisol.

Amy Cuddy describes her 2 min experiment;

“this is what we did; we decided to bring people into a blast and ronaldo experiment and these people adopted for two minutes either high-power opposes or low-power poses.”

The results

High Power Poses produced a 20% increase in testosterone (dominance hormone) and a 25% decrease in cortisol (stress hormone).

Low Power Poses produced a 10% decrease in testosterone (dominance hormone) and a 15% decrease in cortisol (stress hormone).

Simply expanding your body for two minutes produces very significant increases in your hormonal levels. These hormones are the same hormones that drive our confidence and our success in many cases. Amy Cuddy makes a strong case for the body’s ability to influence the way we think. Simply faking a motion for two minutes can convince you that you do belong, you can be successful and that you are powerful.

What I loved about this video is that Dean Potter is so capable physically of allowing his mind to clearly focus on shutting his intuitive muscles down and allowing for the natural process of movement to occur. He is able to quiet his mind of what he should or should not be doing.

Fast forward today and I am reading an article in the NYTimes called Rethinking Sleep. The author talks about the importance of shutting down our mind in order to get a restful nights sleep. It’s not the hours you get, but the quality. Most people do not get the 8hrs their body requires in order to allow the body to recuperate physically and mentally.

“It seemed that, given a chance to be free of modern life, the body would naturally settle into a split sleep schedule. Subjects grew to like experiencing nighttime in a new way. Once they broke their conception of what form sleep should come in, they looked forward to the time in the middle of the night as a chance for deep thinking of all kinds, whether in the form of self-reflection, getting a jump on the next day or amorous activity.”

Dean Potter has the ability to shut down his intuitive active mind. We should all take this as a cue as to why exercise and conscious physical challenges are important to our sleep cycle which allows our brain to do more deep thinking, self reflection and the important rest it needs to recuperate our body for tomorrow.
