Anger is a secondary emotion, it is a mask that covers something much deeper. Anger is an unwanted natural emotion that many people experience from time to time.
Anger develops to help us react quickly to protect ourselves. It arises primarily from an ancient portion of the brain called the amygdala, which triggers automatic responses when we are threatened. Commonly known as fight, flight or freeze.
When distinguishing threats, the amygdala activates the hypothalamus. Which tells our pituitary glands to release the hormones like the stress chemical cortisol, adrenaline and norepinephrine.
Before we are even aware our body is flooded with hormones and neurotransmitters. That shoots up our heart rate, energizes our muscles and increases blood pressure.
Anger actually affects physical health. A Yale university study found that people with anger issues tend to get sick more often. Their anger actually weakens their immune system. The people who respond negatively to anger are 9% more likely to have a heart attack.
