Mitochondria are often called the powerhouses of the cell, but that barely scratches the surface. These tiny organelles don’t just keep the lights on. They are the command centres. They decide when to repair and when to retreat, when to launch an immune attack and when to stand down. They control inflammation, send out distress signals, and shape how every cell in the body interprets its world – is it safe, or is it under siege?
In children with chronic illness, those messages often get scrambled. Mitochondria don’t fail. They adapt. And when they get stuck in survival mode, it’s no longer about boosting energy. It’s about decoding the message. Shifting the body from fear to safety.
This is what we call the Cell Danger Response (CDR), and it flips everything we thought we knew about fatigue, flare-ups, and recovery.
Imagine your child’s cells have an internal alarm system. When they detect a threat such as an infection, a toxin, or a trauma, they sound the alarm. The mitochondria stop making energy and switch to protection mode. ATP, usually the body’s main fuel, is transformed into a cry for help.
This is the body at its most brilliant: a survival mechanism that prioritises protection over performance.
But here’s the catch.
If the threat doesn’t resolve or the body doesn’t realise it has, those alarm bells never stop ringing.
And when that happens, the symptoms can be heartbreaking:
We see it every day in our clinic – in children with autism, PANDAS, PANS, Long COVID, and post-viral syndromes. The original trigger may have passed. But the body hasn’t got the memo. It’s still locked in defence.
Now, here’s where the science gets thrilling and hopeful.
Recent research shows that mitochondria aren’t stuck inside the cells they’re born in. They can move. Yes, move. From one cell to another. Like tiny paramedics, travelling across the body to rescue struggling neighbours.
After a stroke, for example, support cells in the brain send their healthy mitochondria into injured neurons, helping them survive and recover. Damaged lung cells can receive a donation of fresh mitochondria from nearby cells. This isn’t science fiction. It’s happening in real time, in our bodies, every day.
And it’s changing how we think about inflammation, autoimmunity, neurodevelopment, and repair.
So how do we support the body to exit survival mode and re-enter growth, rest, and healing?
Here’s how we approach it in clinic:
We don’t go in guns blazing. We start by turning off the alarms, gently but deliberately. That means addressing:
When the body is screaming “danger!”, nothing else will work.
Mitochondria are wrapped in delicate membranes that act like communication centres. When those membranes are damaged, messages get distorted.
We restore clarity with:
Fix the messaging system, and the body starts to trust again.
Inflamed gut. Inflamed brain. The two are constantly talking, and often, they’re shouting.
We restore calm by:
The goal is safety, not stimulation.
Only once the body feels safe do we begin to feed the mitochondria:
Too much too fast can push the body right back into crisis. Timing is everything.
e’ve witnessed the transformation first hand:
In each case, the mitochondria weren’t broken. They were responding exactly as designed – to danger.
Real recovery isn’t about endless supplements or forcing energy production. It’s about safety. Cellular safety. When the body feels protected, when the danger messages stop, the mitochondria don’t need coaxing. They return to their role of nurturing life.
And with them, come the shifts we long for – energy, joy, sleep, learning, laughter.
The emerging science of mitochondrial transfer and the Cell Danger Response gives us a new roadmap for supporting children with complex chronic conditions. It reminds us: your child’s body isn’t broken. It’s trying to survive. And with the right steps, it can begin to thrive.
