A steady flow of endorphins and Substance P through our bodies strengthens our immune system, keeps us feeling happy, joyful, optimistic and energized. This heightens our sense of well being so that we feel calmer, more centered and focused no matter what kind of stressful events might be happening around us.
Physiologically, these brain chemicals improve circulation, reduce blood pressure, increase body warmth and improve weight control. Kindness helps us relax so that we can connect with others and with our own good feelings.
The reverse is also true. When we are angry with others, it stops the flow of these “feel-good” chemicals. They are replaced by cortisol and other forms of adrenaline that create fight, flight and freeze behaviors associated with trauma and stress.
