Watch for physiological signs of anger. Anger is certainly a psychological emotion, but it is also physiological, involving chemical reactions in your brain. [1] When you get angry, your amygdala, the center for emotional processing, sends a distress signal to your hypothalamus, which sends epinephrine along your autonomic nervous system through the path of the sympathetic nervous system to the adrenal glands, which starts pumping epinephrine (adrenaline) throughout your body. The adrenaline gets your body ready to meet a threat, increasing your heart rate and sharpening your senses. [2]
