Anger creates a surge of energy. When that happens, chemicals such as adrenaline enter the bloodstream. Heart rate and blood flow increase, and the muscles tense. This can compromise the immune system and cardiovascular system, which can even shorten the lifespan when sustained.
Excessive and uncontrollable anger can cause rifts in important relationships, challenges in the workplace, and legal and financial problems. Anger can hijack the ability to think clearly, leading to poor judgment and decision-making. It’s often at the root of substance use disorder, domestic violence, abuse and other conditions.
