Plummeting Estrogen. Starving Mitochondria: Why Rest Feels Like Physical Torture for Neurodivergent Women in Perimenopause
Why scrolling isn't resting — and how to give your nervous system the medicinal cellular repair it's begging for.
I used to think rest was what happened when I'd earned it.
I know better now. Rest isn't the reward at the end of a productive day. It's the thing that makes productivity possible in the first place. It took me years — and a significant chunk of my life spent confined to bed with severe Chronic Fatigue Syndrome, Autistic Burnout, and Hypothyroidism — to truly understand that.
That experience was horrible. But paradoxically, it was also the most valuable education of my life. I now know myself intimately — my energy, my limits, the precise moments when my battery is about to flatline. I've become, for want of a better term, an energy wizard.
What I practice — and what I want to talk to you about today — is something I call Medicinal Cellular Repair (MCR). It has been the single biggest key to maintaining some semblance of stability in my life.
Sounds straightforward, right?
Yeah. It's excruciatingly difficult.
Why Scrolling on Your Phone Is NOT Resting (Even When You're Lying Down)
Let me be clear: lying on the sofa scrolling through your phone is not resting. I know. I'm sorry. But it's not.
When we scroll while exhausted, our overstimulated nervous systems are still processing massive amounts of data. Gentle, rhythmic pottering — the dishes, a slow aimless walk — can be regulating and has its place. But it cannot replace proper, horizontal, sensory-depleted stillness.
It's like trying to charge your phone by turning the brightness down slightly. Helpful? Yes. Enough? Not even close.
The impact on our cells is significant. And to understand why, we need to talk about mitochondria.
What Is the Cell Danger Response? (And Why Your Mitochondria Are Hiding)
Our mitochondria are the tiny engines inside every single cell in our bodies. They produce our energy. And when we're in burnout — real burnout, not just tired — those engines jam.
They decide the world is unsafe, lock their doors, and stop producing power. Scientists call this the Cell Danger Response, and it's exactly as dramatic as it sounds.
To coax those engines back online, we have to send one very specific signal: safety. Absolute, unequivocal, the-bear-has-gone safety.
When we lie down and glue our faces to a phone screen — the rapid-fire videos, the news, the infinite scroll — we are telling every cell in our body that the bear is still absolutely chasing us. We're keeping ourselves in active lockdown, on a biological level, while convincing ourselves we're resting.
And honestly, which of us wanted a science degree just to understand our own bodies? Not me — I'd have taken a PhD in creative writing given the choice. But when you're neurodivergent and your body is falling apart, the unrelenting quest for why takes over and you end up here, elbow-deep in mitochondrial biology, self-taught and bewildered. So here we are.
Here's what blew my mind when I first learned it: the brain has a whole network — called the Default Mode Network (DMN) — that takes up roughly 20% of its total capacity, and it only switches on when we are genuinely, properly doing nothing. Not scrolling. Not pottering. Staring out of a window. Lying in a dark room. Gloriously, productively, medicinally doing nothing.
When this network is allowed to run:
Our brains grow new neural connections
We repair the physical damage of burnout
We protect our long-term cognitive health
When we never let it run:
Chronic overwork physically ages our brains
Our memory centres shrink
Our nervous systems stay locked in low-grade panic
For those of us with ADHD, this lands differently. Our brains are already burning through enormous amounts of energy just to get through a normal day — masking, focusing, executive functioning, surviving. Our mitochondria are running hot before we've even opened our laptops. Letting the Default Mode Network take over isn't a nice idea. It's urgent maintenance.
This is why neurodivergent burnout is a metabolic issue, not just a masking problem. We must stop treating it as anything less.
How Plummeting Estrogen Makes Everything Worse
Here's what nobody warned us about: perimenopause takes everything I've just described and turns the dial up to eleven.
I've been in perimenopause for about eight years. Eight years of not knowing what's coming next — and just when I thought I was finally near the end, after skipping a period for nine whole months, my body sent three back-to-back like some kind of cruel administrative error. Now they've stopped again. I'm exhausted by not knowing, and honestly, at this point, a little bit furious about it too.
This matters, because estrogen isn't just a reproductive hormone. It's deeply involved in how our mitochondria function:
It helps mitochondria produce energy more efficiently
It protects them from oxidative damage
It supports their ability to regenerate
When estrogen drops — as it does, erratically and without warning, across years of perimenopause — our mitochondria lose one of their most powerful allies. And nobody gave us the manual.
So picture this: you're neurodivergent. Your mitochondria are already sensitive, already working overtime. And then estrogen starts falling away. Those little engines have even less support. The Cell Danger Response becomes easier to trigger and harder to escape.
The result?
Burnout arrives faster
Recovery takes longer
The fatigue feels heavier, more bone-deep, more bewildering
Nothing in your life has obviously changed, and yet you feel like you're wading through treacle
Estrogen also props up our dopamine system — the brain's motivation and reward circuitry. When it drops, our already-struggling dopamine takes another hit. Focus gets harder. Motivation evaporates. The pull towards scrolling, sugar, wine — anything offering a quick hit — becomes even more ferocious.
This is precisely why Medicinal Cellular Repair becomes non-negotiable during this phase of life. If you're noticing that your ADHD and autistic traits have suddenly got worse in your 40s, this is exactly why. Our mitochondria need more rest than ever. More, not less. Now, not later.
Why Stopping Feels Like Physical Torture: The Dopamine Detox
So why do we scroll? Why is it so incredibly hard to just stop?
Doing absolutely nothing is physically, psychologically, and emotionally agonising for a neurodivergent brain hooked into a dopamine cycle. Especially one with dwindling estrogen support.
When we're scrolling or hyper-focusing, our brains are getting a potent dopamine hit. When we try to sit in silence and actually rest, the withdrawal feels like a physical ache. We feel agitated, anxious, instantly thrown into flight mode.
It's entirely natural that we reach for our phones, food, wine, or the TV just to medicate that acute discomfort. This, fundamentally, is the root of why I've struggled with so much addiction in my own life.
For those of us with ADHD or autistic traits, task transitions are agonising too. Moving from finishing work to cooking dinner requires a surge of executive function we simply don't have. So we reach for our phones — using the dopamine hit of scrolling as a starter motor to build enough neurochemical momentum to launch into the next part of our day.
When we understand this, we can see it's a highly intelligent survival strategy for a brain running on empty. But because we're sitting still while we do it, we mistakenly label it "rest."
It's not rest. It's a dopamine bridge — and while it gets us to the next task, it leaves our mitochondria starved and locked in the Cell Danger Response.
My Daily 1 PM Sanctuary in Cambodia (And the Resentment It Sometimes Brings)
Every day at 1 PM, right after lunch, I retreat to my bedroom for anywhere between 30 minutes and two hours. Air con on full. Room plunged into darkness. Earplugs in. Eye mask down. Sometimes I sleep. Sometimes I don't.
Before I go in, I stand for a moment in my kitchen. The Cambodian sun is flooding through the windows — that particular midday white light that feels almost aggressive, like it's got a point to make. The heat outside is immense and close. And I turn away from it, and I walk into the dark and the cool, and I lie down.
I have to be honest: sometimes, when the clock strikes one, I feel sad and resentful. I sigh. Especially if I've had a morning of intense productivity and my dopamine is firing on all cylinders. Gimme more, gimme more! My ADHD brain tells me stopping is a terrible idea.
But I always go anyway. Because I know the devastating cost if I don't.
I know not everyone can disappear for two hours. Maybe you've got small children climbing on you, a job that doesn't pause, or a life that simply won't allow it. But:
Ten minutes with your eyes closed in a parked car before school pickup counts
Five minutes lying on your bed with an eye mask while the kids watch Bluey counts
Your mitochondria aren't fussy — they just want the bear to leave
I don't have CFS or active burnout anymore. I've recovered. But for those of us who are neurodivergent — and especially those navigating the hormonal chaos of perimenopause — our mitochondria are highly sensitive. We need this daily respite.
And without fail, every single time, within five minutes of lying down, the magic happens. As the temperature drops, as my eyes feel the profound relief of the dark, as the sensory input drops to zero, my body settles. My nervous system sighs. I think: Ahh, yeah. Here I am.
What happens after MCR? I get my second morning. An afternoon with sharp cognition — work, clients, groceries, a massage. No pushing through. No brain fog. No wishing my brain were different.
How to Start Resting Properly (When It Feels Impossible)
The conditioning that equates rest with laziness — capitalist, patriarchal, deeply ingrained — is incredibly hard to break. Here's what a few friends told me when I asked about their rest habits:
"I do rest, but it always makes me sad... If I rest for too long, I find it almost impossible to re-emerge."
"Unfortunately, my upbringing doesn't allow me to rest. It doesn't fit with the toxic work ethic drummed into me."
"I romanticise about it, but when it comes to it, I believe there are far more important things to be doing."
That first one stopped me. Because that was me, for a long time — lying down and immediately feeling a kind of low-level grief, like I'd stepped off a moving walkway and couldn't work out how to get back on.
I understand now that what I was feeling wasn't laziness or weakness. It was dopamine withdrawal. My brain, screaming for stimulation, trying to convince me that stillness was dangerous.
It's not dangerous. It's the most productive thing you can do.
Here's how to begin:
Start with just 10 minutes — not two hours. Remove the pressure entirely
Remove all sensory input — eye mask, earplugs, dark room, a temperature that feels like relief
Think of it as building a cocoon for your mitochondria — not meditating, not performing rest, just signalling safety
Expect the agitation — let your brain scream for dopamine, because it won't scream for long
Wait for the drop — the moment your body finally realises the bear is gone
What starts as excruciating torture eventually becomes the best part of your day.
The Bottom Line: Stable Energy Is Possible For You
Stable energy is possible for us. I know because I'm living it. But it requires a fundamentally different approach to the one we've been handed — one designed for neurotypical bodies that aren't also navigating a hormonal earthquake.
Please have faith in your recovery. It doesn't look like theirs. It was never supposed to.
Rest isn't just an antidote to exhaustion. It's where our cells repair, our hormones find what balance they can, and our brains quietly grow new connections while we're not looking.
The rest is not separate from your life. The rest is your life. It's the thing that makes everything else possible — the sharp afternoons, the creative work, the capacity to show up for the people you love.
So here's my challenge: ten minutes. Today. Screen off. Eyes closed. Let the agitation come and then let it pass.
Turn away from the light. Walk into the dark. Lie down.
Let your tired, brilliant, overstimulated, hormonally-besieged brain do the one thing nobody ever taught us was productive:
Nothing.
