Why the Advice You Got About Shift Work Sleep Is Wrong
For the first 10 years, we thought we were just bad at shift work.
The weight gain. The bloating. The cravings. The irritability. The bone-deep exhaustion that no amount of sleep seemed to fix. We assumed it was just part of the job. Push through. Tough it out. You'll get used to it.
Except we didn't.
And neither will you—because the advice most shift workers are given is fundamentally wrong.
Advice #1: "Stay Awake All Day After Night Shift"
This was the advice from the veterans. Finish your last night shift, stay awake the entire day (find a pub that opens early), and go to bed at a "normal" time. That way, you'll "reset" your sleep schedule.
Sound logical?
Here's what actually happened:
We'd try to stay awake. We'd fight through the exhaustion. And then we'd wake up on the couch—or worse, in the car on the way to the shops—after an involuntary nap we didn't even remember taking.
Then, when we finally went to bed at our "normal" time, we'd be wide awake at 4am, feeling wrecked. Eventually, we'd crash again mid-morning, wake up groggy, caffeinate hard, and spend the rest of the day in a fog.
Why this doesn't work:
Your body is already running on fumes after a night shift. Forcing yourself to stay awake for another 12+ hours doesn't "reset" anything—it just pushes you deeper into sleep deprivation. And when your brain is desperate for rest, it'll take it wherever it can get it.
Advice #2: "Sleep as Long as You Can to Catch Up"
So we tried the opposite approach: sleep as long as possible after night shift. "Catch up" on all that lost sleep.
But that had its own problems.
We'd sleep until midday or later. Then we couldn't fall asleep that night. And we'd spend our days off dragging through with no energy, no rhythm, and no recovery.
Why this doesn't work:
Sleeping until later shifts your circadian rhythm even further out of sync. You're training your body to think your wake up time is morning. So when you try to go to bed at a "normal" time, your brain says no thanks, we're just getting started. And you end up exhausted but wired—never fully recovering.
Neither Approach Respects How Your Body Actually Works
Here's the thing: both of these strategies ignore how your circadian system actually functions.
Your body doesn't "reset" on demand. It doesn't "catch up" on sleep the way you catch up on emails. It operates on biological rhythms that have been hardwired into you for millions of years.
And when you work against those rhythms—whether you're forcing yourself to stay awake or sleeping half the day—you're not fixing the problem. You're making it worse. Every part of you has its own clock and you're making your body fight itself.
For 10 years, we lived in that fog. Snapping at our families. Making mistakes at work. Missing out on life because we were too tired to show up. And the worst part? We thought it was just how shift work is supposed to be.
Turns out, it wasn't. It was the advice.
What Actually Works
It wasn't until we started digging into the research—really understanding how sleep deprivation, ATP production, body clocks and recovery work—that things changed.
That's what we're covering in Part 3: what actually helps, what we changed, and how we rebuilt our lives around shift work. It's no exaggeration to say we are now thriving, as we enter our 40s and after over 15 years of shift work, we have never felt or coped with it better.
