The Impact of Anger on Your Brain and Body: What Happens When You Lose Control

When anger strikes, the brain’s amygdala triggers a “fight or flight” response, releasing adrenaline and cortisol.

Your heart races, muscles tense, and your mind focuses intensely on the threat. This reaction can be helpful in emergencies, but if chronic, it harms your health—raising risks of heart disease, anxiety, and depression.

The Brain on Anger

The brain’s amygdala acts as an alarm system, detecting threats and triggering emotional responses like anger. When activated:

• The fight or flight system kicks in.

• The prefrontal cortex (responsible for logic and reasoning) may be suppressed.

• This shift makes you more reactive and less able to think calmly or solve problems.

Over time, repeated anger spikes can rewire the brain, strengthening neural pathways that make angry reactions more automatic.

The Body on Anger

Anger triggers a stress response:

• Increased heart rate and blood pressure

• Muscle tension, especially in the jaw, neck, and shoulders

• Rapid, shallow breathing

• Release of stress hormones like cortisol and adrenaline
  

Chronic anger or frequent outbursts can contribute to health problems such as:

• Cardiovascular disease

• Immune system suppression

• Digestive issues

• Sleep disturbances

Real-Life Example:

Peter’s constant frustration at work caused him to have frequent headaches and insomnia. Over time, he noticed his relationships suffering. After counselling, Peter learned relaxation techniques and mindfulness to calm his nervous system and reduce stress.

Emotional and Social Impact

Anger can cause:

• Strained relationships or social isolation

• Loss of trust or respect

• Legal or financial consequences (e.g., from aggressive behaviour)

• Emotional exhaustion or guilt

How Counselling Helps

Therapy aims to:

• Help you understand your brain-body connection during anger.

• Teach regulation skills to calm the nervous system.

• Provide tools to interrupt angry impulses.

• Explore emotional triggers and work through unresolved trauma.

• Improve communication to express anger constructively.
