Anger is a common emotion in conflict situations that does not need to lead to ineffective reactions if managed properly. Anger signals the body to prepare for a fight and can have adverse health effects if not addressed. Steps to manage anger include recognizing early signs, regulating emotions, and expressing emotions constructively rather than through verbal or physical attacks. When dealing with others' anger, it is important to listen without counter-attacking, help them calm down, and look for options to resolve the conflict collaboratively.
