Anger is one of the most important components of our core moral values. This is exactly what psychologists see as one of the main tasks of emotions: They let us feel what is good for us – and what is rather bad. When we are wronged, norepinephrine flows through the body. Heart rate and blood pressure rise, we knit our eyebrows and press our lips together, our stomachs cramp, our shoulders tense up, we sweat – we are angry. Only: How much anger is normal? And should you let them out or breathe away?
