Aggression is a complex and often misunderstood behaviour that can affect both the individual experiencing it and those around them. Whether it appears as verbal outbursts, physical violence, or passive-aggressive behaviour, understanding what drives aggression is essential to managing it effectively. In this post, we’ll explore some of the common causes and triggers of aggression, and how psychotherapy at CARESPACE can help individuals develop healthier ways to cope and communicate.
Root Causes of Aggression
One of the most common sources of aggression is unresolved anger. When anger isn’t processed or expressed in healthy ways, it can build up and lead to explosive reactions. This is often the case for individuals who have experienced trauma or stressful life events that leave them feeling powerless. Psychotherapy offers a supportive space to explore these emotions, understand their origins, and develop more constructive ways to manage anger.
Underlying mental health conditions such as depression or anxiety can also contribute to aggression. When individuals feel constantly on edge or emotionally dysregulated, they may become more reactive. Therapy helps address these conditions, improving emotional regulation and reducing aggressive responses.
Common Triggers of Aggression
Aggression can also be triggered by external or situational factors. Stress is one of the most common triggers—high stress levels can lead to irritability and a shorter temper. Through psychotherapy, individuals can learn mindfulness, relaxation, and stress management techniques to help prevent escalation.
Trauma can be another powerful trigger. Those who have experienced past trauma may respond aggressively as a way to protect themselves from perceived threats. Therapy supports clients in processing trauma, resolving lingering fear or anger, and rebuilding a sense of safety.
Substance use can also heighten aggression by lowering inhibitions and impairing judgment. Addressing substance use in therapy helps individuals identify triggers, build coping strategies, and reduce the risk of aggression tied to alcohol or drugs.
Sometimes, aggression arises from unmet emotional needs such as lack of validation, attention, or support. In these cases, aggressive behaviour can be an attempt to communicate distress. Psychotherapy helps individuals identify their needs and learn healthier, more effective ways to express them.
Environmental and Social Factors
A person’s environment also plays a key role in shaping aggression. Growing up in a chaotic or violent home, experiencing bullying, or being exposed to media that glorifies hostility can normalize aggressive responses. In therapy, individuals can explore these influences, challenge unhelpful patterns, and develop new, more adaptive behaviours.
Working Toward Change
There’s no single explanation for aggression—it often stems from a mix of biological, psychological, and social factors unique to each person. Through psychotherapy, individuals can gain insight into what fuels their aggression, learn to manage triggers, and build healthier coping mechanisms.
