Is it healthy to suppress anger?

Evolutionarily, anger helps us survive and react to perceived threats. It is linked to our sympathetic nervous system’s ‘fight, flight or freeze’ response.

Anger, often deemed the forbidden emotion in our society, is frequently labelled as ‘bad’. It is seen as the ‘black sheep’ of emotions, and forced to be buried deep within by the walls built inside us by society. It is often unwelcome: a trespasser in the garden of civility. But does masking it with an ingenuine but polite smile truly resolve its cause? Or does it merely complicate matters, allowing it to fester until it explodes later? Also, is it as bad as portrayed?
