The heart and your emotions

Your heart matters if you want to make good decisions, and be able to self regulate your emotions, be cool to work with, and be kind to others.

Cortical inhibition can be a good thing until it´s not.

"Utilizing HRV analysis, we have demonstrated that distinct heart rhythm patterns characterize different emotional states. In general, emotional stress—including emotions such as anger, frustration, and anxiety—leads to heart rhythm patterns that appear incoherent"

"This desynchronization in the ANS, if sustained, taxes the nervous system and bodily organs, impeding the efficient synchronization and flow of information throughout the psycho-physiological systems. This, in turn, results in cortical inhibition, which impairs cognitive functions and diminishes one's ability to think clearly, discriminate among behavioral choices, and self-regulate emotions"
