Anger Is Natural. Losing Control Isn’t. Here’s Why

Your heart starts racing, your face turns red, and suddenly you say something you regret. The reason is that, at the moment, your brain loses control over anger.

So, what really happens inside your brain when you get angry, and how can you manage it?

From a scientific perspective, anger can be seen as a form of defence mechanism. We express anger when we strongly dislike something and feel threatened.

Almost all living creatures have some form of defence mechanism. Even the plants secrete various chemicals to protect themselves from threats.

Anger is essentially a negative emotional response.

According to evolutionary theory, anger is one of the most primitive human emotions. It evolved over millions of years and played an important role in the survival of our species.

Our ancestors used anger as a response mechanism to deal with threats from predators and to compete for limited resources.

But anger is not only a defence mechanism.

If that were the case, why do we become angry even with our loved ones, such as our spouse, children, or other family members?

Anger can serve as a way of maintaining balance. Alternatively, it can be strategic and considered a healthy form of anger.

For example, parents may express anger when their children are stubborn, hoping to guide them toward appropriate behaviour.

Sometimes, we feel angry with our partner when the balance in our home or relationship is disrupted.

Therefore, anger is not harmful; rather, it is a necessary emotion.

However, anger becomes problematic when it begins to affect one’s personality.

Some people are short-tempered, while others may react violently.

These behaviours are not universal, but are likely person-specific, and may also be influenced by genetics.

It is unclear whether such behaviours can be improved, managed or changed.

Both behaviours can harm us by devaluing our personality. If you express anger frequently, people may begin to ignore you, and it rarely leads to positive outcomes.

For example, if you are a CEO in a company or institution and you frequently display anger, especially without justification, your colleague may stop taking you seriously.

Over time, your anger loses its impact and credibility.

Violent anger is always destructive. It can damage relationships and harm one’s reputation, and may even lead to criminal acts.

Such behaviour can also undermine the social capital we build over a lifetime.

In our society, we have observed that uncontrolled anger has led to criminal acts.

Sometimes, even a gentle and well-respected person may commit a crime as a result of losing control over their anger.

When anger becomes intense and crosses a certain threshold, we tend to act on impulse rather than reason.

It is often said that a person’s true character is revealed when they are insulted, because in such moments, anger can expose one’s inner self.

Therefore, it is important to remain calm and keep a cool head, even when someone insults you, especially when you have done nothing wrong.

I recall the recent Gen-Z movement that erupted in Nepal. During the protests, 76 citizens were shot dead by government forces.

In response, widespread public anger led to violent unrest, and several state buildings, including government offices, the parliament, and the Supreme Court, were set on fire.

After the revolt settled, footage related to the movement gradually began to surface.

Several celebrities were seen among the crowds. In the videos, they appeared and used harsh language, prompting widespread public criticism.

What science says about anger?

Anger originates in the brain, particularly in a small almond-shaped structure called the amygdala, which processes emotional response.

When activated, it releases stress hormones, including cortisol and adrenaline.

These hormones increase blood flow, warm the body, and may cause facial flushing, while also raising heart and respiratory rate.

At times, when we experience intense emotions or perceive danger, the amygdala prepares the body for defence.

At the same time, the logical part of the brain, the prefrontal cortex, struggles to process what is happening, and we tend to react on instinct.

Experts suggest that genetics influences brain structure, serotonin levels, and temperament.

Studies indicate that genes may account for about 50% of the variation in anger expression.

Researchers have also identified eighteen specific genetic variations associated with aggression.

As described above, anger is basically an obvious natural emotion; chronic anger may increase the chances of heart disease as well as high blood pressure, which can lead to the risk of heart attacks.

Well-known Psychiatrist and neuroscientist Daniel J. Siegel suggests that ‘we should not respond immediately in a heated situation.

Before we respond, we should first allow our nervous system to calm down’.

If you are short-tempered, experts suggest finding healthy ways to process your anger, like meditation and mindfulness.

Healthy anger means developing effective strategies to respond to different situations.

Finding healthy ways to express anger is important.

Learning to control and express it appropriately can help you build better relationships, achieve your goals, and lead a healthier, more fulfilling life.
