Brain Hacks: Help your child feel better without screens or lectures!

There is a moment we see in the Clinic regularly. A child comes in wound up from school, buzzing with leftover stress, and the parent says, “They’ve been like this all afternoon. I don’t know what to do with them.”

What’s often happening inside that child is a nervous system that’s been running on stress chemicals, cortisol especially, for hours. What they need, more than a talking to or a screen, is a gentle reset.

These strategies are fundamental for all kids. Every child, just from the ordinary demands of living, school, friendships, screens at home and in the classroom; can become depleted and in need of a reset. But these strategies matter especially for children and teenagers who have a pattern of struggling with emotion regulation, who are prone to anger outbursts or the dreaded “I’m bored,” who have trouble staying stimulated, or who are perpetually over-stimulated. And for our sensitive kids, those who feel the feels strongly, and carry an activated body and brain as a result, these tools can be genuinely life-changing.

The good news is that neuroscience gives us some genuinely fun, sometimes surprising tools to help children and teenagers shift their brain chemistry. These aren’t gimmicks. They’re backed by what we know about how the brain actually works. And most of them take about thirty seconds.

First, a Quick Bit of Brain Science

Two chemicals are worth knowing about here.

Cortisol is the stress hormone. It’s essential in genuine danger - it sharpens focus, boosts alertness, and prepares the body for action. But when cortisol stays elevated for too long, it makes children reactive, irritable, overwhelmed, and hard to reach. Chronic stress keeps the brain stuck in survival mode, which is the last place learning, connection or calm can happen.

Dopamine is the brain’s reward and motivation chemical. It rises when something feels interesting, rewarding, fun or novel. Jonathan Haidt’s research highlights how dysregulated dopamine has become for many children - overstimulated by social media and passive screen use, and understimulated by the kinds of real-world experiences that build genuine wellbeing.

The strategies below are designed to gently lower cortisol and nudge dopamine in a healthy direction, through novelty, play, laughter, and a few things your child definitely won’t see coming.

A quick note on timing

These strategies work best when a child is mildly dysregulated - grumpy, wound up, or flat. If they’re already in full meltdown, the priority is co-regulation first: calm presence, a quiet space, less talking. Once the nervous system starts to settle, that’s when these ideas shine.

1. Novelty: The Brain’s Favourite Wake-Up Call

The brain is wired to pay attention to things that are new, unexpected, or surprising. When something novel happens, dopamine spikes, not because it’s pleasurable, but because the brain registers it as worth paying attention to. It’s one of the quickest natural dopamine triggers we have.

This is why children who seem completely switched off can suddenly light up when something unexpected happens. Novelty interrupts the stress loop.

Some simple ways to introduce novelty:

• Serve dinner in a completely unexpected way e.g. backwards (dessert first, tiny portions), on a tray in the lounge room, or with everyone eating left-handed.

• Change something small without explanation and wait to see if they notice. Children love catching adults out.

• Take a different route home. Walk somewhere new. Rearrange the furniture slightly. The brain’s “what’s different here?” response is genuinely regulating.

• Try a completely random activity e.g. write five activities on pieces of paper, put them in a jar, and let them pull one out. The act of not knowing what’s coming is its own dopamine hit.

  
  

For teenagers, novelty matters even more. The adolescent brain is in a period of heightened dopamine sensitivity and is actively seeking stimulation. When we can offer real-world novelty - new experiences, new challenges, unexpected moments - we’ are feeding a genuine neurological need.

2. Laughter: The Fastest Cortisol Reset We Have

Laughter is, quite literally, medicine for the stressed brain. Research consistently shows it lowers cortisol, releases endorphins, and activates the parasympathetic nervous system - the body’s “rest and digest” state that is the opposite of stress.

Dr Laura Markham talks about the power of playfulness in rebuilding connection with children after tension and it works because laughter signals safety. When a child laughs with you, their nervous system receives a very clear message: “I am not in danger. I am okay.”

A few ways to introduce laughter when the mood is heavy:

• Tell a genuinely terrible joke. The worse the better. Dad jokes exist for a reason.

• Introduce a ridiculous rule for five minutes — everyone has to speak in a silly accent, or respond to everything with a sound effect.

• Be unexpectedly silly yourself. When a stressed child sees their parent being ridiculous, it is often disarming in the best possible way.

• Watch a funny video together. Shared laughter, even from a screen, activates the same bonding chemicals as laughing in person.

  
  

The key is genuine lightness, not forced cheerfulness. Children are exquisitely sensitive to authenticity. A real laugh from a parent is far more regulating than a performed one.

3. Turning the Hard Thing Into a Game

One of the most effective (and underused) tools in a parent’s toolkit is gamification - turning a routine, a chore, or an anxiety-provoking task into something with challenge, unpredictability or reward built in.

When a task feels like a game, the brain processes it differently. Dopamine rises in anticipation of reward. Cortisol drops because the sense of threat is reduced. And crucially, the child moves from resistance to engagement — often without even realising it.

This works particularly well for tasks children typically avoid, like getting ready in the morning, doing homework, tidying a room, or tolerating something boring.

Some ideas that actually work in practice:

• The timer challenge. “I wonder if you can get your shoes on before I count to twenty.” This works best when you actually count theatrically slowly and let them beat you.

• The ridiculous points system. Assign wildly arbitrary points to boring tasks. “You get three hundred points for putting your plate in the dishwasher.” No prize required -children often just enjoy the absurdity.

• Beat the robot. Tell your child you’re going to give them instructions like a robot and they have to carry them out as fast as possible. Use a monotone voice. It’s funnier than it sounds.

• The mystery envelope. Write a task on a piece of paper and seal it in an envelope. The child doesn’t know what it is until they open it. Even mundane tasks feel more interesting with a bit of drama.

• Two truths and a task. Mix one real job with two ridiculous fake ones. “Your options are: unload the dishwasher, iron the cat, or vacuum the ceiling.” Children almost always pick the real task when the alternatives are absurd enough.

  
  

For teenagers, gamification needs to feel slightly more sophisticated. However, the principle still holds. Challenges, friendly competitions, time-pressure tasks, and choice all activate the same dopamine pathways. The key is letting them feel some sense of autonomy and mastery.

A note on using these strategies

These tools are most effective when they come from a place of genuine connection, not desperation. Children pick up on the difference between a parent who is playfully engaged and one who is performing playfulness to manage behaviour. If you’re exhausted or frustrated, that’s okay. Start small. Even one tiny unexpected moment can shift the chemistry in the room.

4. A Few More Rapid Brain Resets Worth Knowing

Beyond novelty, laughter and play, there are a handful of other evidence-supported strategies that help shift the nervous system quickly:

• Movement. Even five minutes of physical activity — a quick run around the garden, a dance in the kitchen, jumping on a trampoline — significantly lowers cortisol and boosts dopamine. The body was designed to move stress through the system physically.

• Cold water. Splashing cold water on the face activates the dive reflex, which slows heart rate and triggers the parasympathetic nervous system almost immediately. It sounds odd. It genuinely works. Humming or singing. Stephen Porges’ Polyvagal Theory explains why vocalisation, especially with rhythm and tone, activates the vagal nerve and signals safety to the nervous system. Singing in the car together isn’t just fun. It’s regulating.

• Doing something with their hands. Drawing, building, kneading dough, or even just fidgeting with something textured can help bring a child back into their body and out of their head.

What all of these strategies have in common is that they work with the brain, rather than against it. They don’t ask a stressed child to “just calm down” or reason their way out of a dysregulated nervous system. They create the biological conditions for calm, engagement and connection to be possible.

Maggie Dent often talks about the power of play as a serious developmental tool,. not a reward for good behaviour, but a fundamental need. When we make space for laughter, novelty and lightness, we’re not abandoning structure or letting children “get away with things.” We’re actually doing some of the deepest nervous system work available to us as parents.

And if none of this comes naturally at first, that’s okay too. Start with one thing. Tell one terrible joke. Take a different route home. You might be surprised what shifts! My kids, especially my biggest one, tends to roll their eyes at me at first, but they actually really love it - and to see the genuine interest, engagement and often joy on their little faces, is priceless!
