This emotion is familiar to all of us.
In fact, there is a complex series of physiological (body) events that occurs as we become angry.
Emotions more or less begin inside two almond-shaped structures in our brains which are called the amygdala. The amygdala is the part of the brain responsible for identifying threats to our well-being, and for sending out an alarm when threats are identified that results in us taking steps to protect ourselves.
As you become angry your body's muscles tense up. At the same time your heart rate accelerates, your blood pressure rises, and your rate of breathing increases.
Your face may flush as increased blood flow enters your limbs and extremities in preparation for physical action.
Your attention narrows and becomes locked onto the target of your anger. Soon you can pay attention to nothing else. In quick succession, additional brain neurotransmitters and hormones (among them adrenaline and noradrenaline) are released which trigger a lasting state of arousal. You're now ready to fight.
When you calm down and analyze the situation, it is possible that you will not be able to remember many details, because the ability to concentrate due to anger was significantly impaired.
As you can see, this emotion is detrimental to both you and those around you, and it is desirable to learn to manage it.
