Research has shown that positive and negative interactions have powerful and distinct impacts on brain chemistry. Harvard Business Review recently published an article on the neurochemistry of positive conversations. The research looked at what happens in a person’s brain following positive and negative interactions.
Following negative interactions, levels of cortisol spiked and stayed elevated for over 24 hours.
Cortisol is a stress hormone that serves to shut down the thinking center of the brain and activate conflict-aversion and protection behaviors.
