The unexpressed anger contributes to physical and emotional tension. The expression of anger releases that tension. Without healthy ways to express anger, unexpressed anger builds up and can result in physical symptoms such as headaches, body tension, indigestion and anxiety.
There are those who claim they 'don't get angry'. Outwardly they may appear calm and unfazed. Again, this could be a result of witnessing negative expression of anger in their past. However, this tension still exists and builds up, adding to the emotional 'gunnysack'. A seemingly trivial event can trigger an explosive expression of anger.
For example, an unwashed teacup is the trigger for an all-out argument over who does their fair share, which leads to who contributes and to personal attacks and so on.
There are ways to express anger that are productive and allow us to maintain hones relationships with those around us, even during difficult times.
Expressing our anger does not mean that the cause of the anger has been addressed or resolved but, when we release some of the tension, we have more energy to address the situation.
