Why Kids Are My Kids Out Of Control? When Big Emotions Take Over

Anyone who has spent time around kids knows one thing to be true; big emotions can show up fast.

One minute everything is fine. The next minute there are tears, yelling, slammed doors, or even physical retaliation. From the outside, it can look dramatic. They seem to be acting irrational.

But what is actually happening inside the body tells a different story.

We all have something called the fight or flight response. It is part of our nervous system and its job is simple: keep us alive. When the brain senses a threat, whether it be real or perceived, it flips a switch. Buh-Bum, Buh-Bum, Buh-Bum. The heart rate increases. Breathing gets faster and blood rushes into the body's limbs as the muscles tighten. Stress hormones are quickly released into the body as a sort of fire alarm system. The system is preparing to fight the danger or run from it.

Here’s the thing: Our bodies do not understand the difference between a dangerous threat and a minor threat. It does not differentiate between running from a hungry lion and our feelings being threatened. The nervous system responds by flipping the switch to protect you. Any threat needs to be protected.

An embarrassment in front of classmates. Someone physically cutting into the line. A sibling snatching a toy. Another kid at school saying mean things. A bully pushing you around.

To the nervous system in times of threat, it all feels important to what matters most, you.

Let’s break this down to understand more what is actually happening. Some people call it “flipping the lid.” When the emotional center of the brain becomes overloaded and fight or flight is turned on, the prefrontal cortex, the part responsible for logical thinking, decision-making, and impulse control essentially shuts down.

In other words, when emotions spike high enough, logic steps aside.

This is why a child who knows they should not, can still find themselves hitting back. This is why a student who is normally respectful can suddenly yell at a teacher or friend. This is why a kid being bullied might either explode in anger or completely shut down.

The body has taken over.

In martial arts, we see this clearly.

A student puts themself in a literal fight or flight situation. While the nervous system is locked into fight mode, they must learn to remain logical. Critical decisions still need to be made. A martial artist learns to control their breathing in a fight, manage their impulses in order to fight strategically rather than emotionally. Believe me, I have made the errors of an emotional reaction that has come at the expense of loss and injury. And, I learned how that does not work for me to succeed. The practice of having to remain calm in the state of survival has been a crucial part of the man I have become. The ability to pause in a heated conversation, walk away from a dangerous encounter, and manage my anxiety in life.

We do not “flip our lid” because we lack an understanding that it’s wrong in certain situations. It happens because the nervous system perceives a threat and shifts into survival mode and when survival mode takes over; access to calm, rational thinking decreases. Before we can think through the consequences, we find ourselves in a regretful situation.

Big emotions are not the enemy, they are signals. The real skill is learning how to work with the nervous system instead of being controlled by it. As I highlighted, in martial arts training, this is one of the most important lessons we teach. We are not just building stronger bodies, we are building stronger self-regulation. Anyone can learn these skills though, not just the ninjas in the dojo!

When a child learns to recognize what is happening in their body “My heart is racing. My fists are tight. I feel my face getting warm.” They gain a small but powerful window of choice. That pause and awareness is powerful. With practice, it can become more and more automatic during stressful situations.

Instead of hitting back, they begin to step away. Instead of yelling, they pause and use words. Instead of freezing, they ask for help.

This is not about suppressing emotion, it is about developing the strength to manage it. Like a muscle, it needs repetitions to get stronger. 

Children are not “bad” when they flip their lid. They are overwhelmed. They are navigating not only the big emotions that feel uncontrollable, but the guilt and shame that follows. And our role as adults, parents, coaches, and teachers is not just to punish the behavior. It is to help them build the skills to navigate the surge because one day, they will not just be managing playground conflicts. They will be managing relationships, careers, and families.

If they can learn early that big emotions are natural, that the body reacts before the brain thinks, and that control can be trained, they can develop something far more valuable than obedience.

They develop self-mastery.

And that is a skill that creates leadership and success in today’s world.
