Have you ever noticed that the only time you give yourself full permission to do absolutely nothing is when someone or something else has made the decision for you? I have. I’m fifty-five years old. I’m a psychologist. I’ve spent decades studying human behavior, and I still couldn’t grant myself permission to nap on a Sunday afternoon until roughly three years ago. But put me in seat 14C on a Melbourne-to-Perth flight and I’m unconscious before the seatbelt sign turns off.

This contradiction lived in my body for forty years before I understood what it actually was. And once I did, I realized it had very little to do with sleep and almost everything to do with the architecture of permission that most of us never consciously examine.

The Alarm That Set the Pattern

My father woke at 3:45 AM every day for thirty years. I heard it through the thin wall between our bedrooms, that metallic chirp followed by the immediate creak of his feet hitting the floor. There was no snooze button. There was no lying there for five minutes gathering himself. Alarm, feet, floor. Every single morning.

He worked double shifts. He slept roughly four hours a night. After my mother died when I was twelve, he was the only parent I had, and what I absorbed from watching him wasn’t a philosophy about hard work. It was a nervous system template. Rest was what happened when your body physically collapsed. Everything before that point was available time, and available time had obligations.

By my thirties, my alarm was set for 4:15 AM. I told myself it was discipline. I was building a clinical practice in Melbourne, raising Sophie largely on my own, maintaining a reputation for being steady and composed. I slept four, maybe five hours a night. I wore that schedule like a professional credential, the same way I wore composure: as proof that I was managing, that nothing was falling apart, that I had inherited my father’s capacity to keep going.

What I’d actually inherited was his inability to stop.

Why the Plane Works

Here’s what I’ve come to understand about why I could sleep on flights but not in my own house on a Saturday. The plane removes the variable that kept me awake everywhere else: choice.

At cruising altitude, you cannot answer emails productively (or at least you couldn’t for most of my flying years). You cannot do laundry. You cannot reorganize the hall cupboard or review client notes or call the school about Sophie’s excursion form. The environment is sealed. The expectations are zero. And crucially, everyone around you is also doing nothing. There’s no comparative productivity happening in row 15 that makes your stillness look like failure.

The plane is a container of enforced uselessness, and for someone whose nervous system had spent four decades equating stillness with danger, that container was the only thing strong enough to override the alarm.

I see this pattern in my practice constantly. Clients who can only relax on holiday (and even then, only by day three). Clients who feel a wash of anxiety the moment they sit down without a task. Clients who describe weekends as “worse” than work because at least work provides structure, and structure provides justification for existing. The underlying current is always the same: rest feels safe only when it’s externally imposed.

Productivity Guilt Has a Name Now

Psychology has started calling this productivity guilt, a persistent sense that leisure or rest is undeserved unless you’ve “earned” it through sufficient output. Clinical frameworks often describe it as a cognitive distortion, a belief that your worth is contingent on your usefulness. But what that framing sometimes misses is the biographical infrastructure underneath. Productivity guilt doesn’t appear from nowhere. It’s built, brick by brick, in childhoods and family systems where love and survival looked like labor.

My father’s journal entry from 1987, which I found after he died: “Tired today but there’s no room for that.” Seven words. An entire worldview. I carried that worldview into my thirties, forties, and most of my fifties without ever articulating it as a belief. It just felt like reality. Tired today but there’s no room for that. So you keep going. And the body adapts, the way bodies do, by cortisol-driven hypervigilance that starts to feel like normal operating temperature.

The Nervous System Doesn’t Care About Your Calendar

One thing I’ve learned from both clinical work and personal experience is that the nervous system doesn’t distinguish between “I’m resting because there’s nothing urgent” and “I’m resting because I’ve given up.” Clinical understanding suggests that for people who grew up in environments where vigilance was required for survival (emotional or physical), the internal alarm system can treat stillness as a threat state. Your calendar can be empty. Your to-do list can be cleared. Your conscious mind can know, rationally, that you deserve a break. But the body keeps scanning.

This is why I could sit in my own living room on a Sunday, exhausted after a sixty-hour week, and still feel the pull to get up and do something. My body read the open environment, the available time, the absence of external structure, and interpreted all of it as vulnerability. Something should be happening. If nothing is happening, something is wrong. If something is wrong, you need to be ready.

The plane eliminated that loop. The seatbelt was a physical boundary. The roar of the engines was white noise that flattened my threat detection. The finite duration of the flight (two hours, four hours) gave rest an endpoint, which made it feel contained rather than open-ended. And open-ended rest was what terrified me, because open-ended rest looked, to my nervous system, exactly like the directionless grief of being twelve and motherless.

What Changed at Fifty-Five

I sleep seven hours most nights now. I fall asleep easily, which still startles me. The shift didn’t come from a meditation app or a sleep hygiene checklist, though I’ve recommended both to clients over the years. It came from finally understanding what my sleeplessness was protecting me from.

In my late forties, I went through a period of being unwell. I also lost a close friendship, a woman I’d known for nearly fifteen years, and that loss hit harder than I expected. I’ve written before about how never showing weakness can quietly corrode your support systems, and I was living proof. My composure had trained everyone around me to believe I was fine. So when I wasn’t fine, there was no infrastructure for being seen.

That period cracked something open. The performance of relentless capability became too expensive to maintain, and when it broke, what flooded in wasn’t collapse. It was information. Decades of accumulated fatigue that I’d been metabolizing as discipline. The understanding that my father’s 3:45 alarm wasn’t something to replicate. It was a wound dressed up as a work ethic.

He died at sixty-two from a heart attack. As the saying goes, the body keeps the score, but it also keeps the invoice.

The Permission Problem

Most of the clients I see who struggle with rest share a common feature: they can articulate, intellectually, that rest is necessary and healthy. They understand the connection between sleep duration and cognitive decline. They understand that chronic exhaustion is unsustainable. And they still can’t do it. The gap between knowing and doing is wide enough to lose years in, and what fills that gap is almost always a permission structure that was never built.

Children who grow up watching parents rest learn that rest is part of the rhythm of living. Children who grow up watching parents push through exhaustion learn something different: that the rhythm of living has no rests. Only held notes.

I was a held note for forty years. The plane was the only place the music stopped.

What External Permission Looks Like

It looks like the plane. But it also looks like illness (“I can rest because I’m sick”), like doctor’s orders, like someone else insisting. I’ve had clients who could only justify a nap by telling themselves they’d be “more productive after.” Rest had to be laundered through productivity to be acceptable. The nap wasn’t for them. It was for the work that came after.

This is what I mean when I say the plane was structurally justified. It gave me an external excuse that my internal system would accept. You are in a sealed metal tube. There is nothing you can do. Therefore, you are not failing by doing nothing. The logic was airtight, and apparently that was what my nervous system required: an airtight case for stillness.

I came across a video recently by Justin Brown that explores why doing nothing is actually good for you, and it articulated something I’ve spent decades trying to untangle in my own practice—the way our culture has made rest feel like a moral failing rather than a biological necessity. It’s worth watching if you’ve ever needed permission to stop moving.

Building Internal Permission

I don’t have a tidy framework for how I learned to rest on the ground. It happened slowly, in the messy way real change usually does. Part of it was the clinical knowledge catching up with the personal resistance. Part of it was age, the body’s quiet insistence that fifty-five cannot run on the fuel budget of thirty-five. And part of it was the grief work I finally did around my father, understanding that his sleeplessness was a form of performing endurance rather than a model to follow.

After he died, I found a box in his closet containing every item I’d ever given him. Birthday cards from age five. A clay ashtray from primary school. A pressed flower from a bushwalk when I was nine. Everything organized by year in dated envelopes. He had been paying attention the whole time, in the only way his own nervous system allowed: silently, methodically, in private.

He couldn’t rest either. He couldn’t say he was proud. He could only collect evidence of love in a shoebox and hope someone found it later. And I could only sleep at 35,000 feet, in a context so constrained that even my most vigilant self couldn’t find a reason to stay awake.

We were the same person, my father and I. Running the same software on different hardware. And the software’s core instruction was simple: don’t stop, because stopping means something terrible might catch up with you.

What I Tell My Clients Now

When clients describe feeling guilty about rest, I don’t reassure them that they deserve it. They already know that. Knowing has never been the problem. Instead, I ask them: What does rest look like in the absence of permission? And then I watch their faces, because the answer is almost always the same. Confusion. Because rest without permission, rest that is chosen rather than imposed, is a concept their nervous system has never encountered.

I spent forty years watching my own mind with suspicion every time it suggested slowing down. And the flights, the blessed, rattling, pressurized flights, were the only place the suspicion lifted. That’s a strange way to live. But I don’t think it’s an uncommon one.

I nap on Sundays now. Sometimes on the couch, sometimes in bed with the curtains drawn at two in the afternoon. No justification. No productivity reframe. Just a woman lying down in the middle of the day because she is tired, and that is enough.

It took fifty-five years to get here. And honestly, I still sleep better on planes.
