Mad, or angry, is an emotional response to perceived threats, injustices, or frustrations. It can manifest in various ways, including irritability, frustration, or even rage. This emotion is a natural part of human experience and can serve as a signal that something is wrong or needs to be addressed. When someone feels mad, their body may react with increased heart rate and adrenaline, preparing them for a fight-or-flight response. While anger can motivate action, it can also lead to negative consequences if not managed properly. Understanding and expressing anger in healthy ways is important for emotional well-being.
