People have different physical responses to anger, but some of them may include teeth grinding, flushing, paling, fists clenching, prickly sensations, sweating muscle tensions, temperature changes and numbness.
Anger usually is obvious by our facial expressions.
Women often describe anger as a slow burn, while men describe it as a fire or flood that rages within them. It also varies by cultural norms. Some Asian cultures, for instance, experience anger in a milder way and for a shorter period of time than Caucasian Americans.
In either case, your body is gearing up to survive or fight the wrong that has been perpetrated against you. Chemicals like noradrenaline and adrenaline surge through the body.
