Why You Can’t Just “Try Harder” to Sleep (And What Actually Helps)

It’s 11pm. I should go to bed. I’ve been exhausted since about 3pm.

But I’m on the couch scrolling through my phone instead, watching videos I’m not even interested in, because this is the first quiet moment I’ve had all day. My daughter is asleep. No one needs anything from me. And I’m not ready to give that up yet.

There’s a name for this, apparently. Revenge bedtime procrastination. (I didn’t make that up. It’s a real thing.)

The problem is, when I finally do go to bed—usually well after midnight—I can’t sleep. I’m lying there, exhausted, while my brain decides to run through the week’s to-do list. The email I forgot to send. Whether I paid the rego. What I should have said in that conversation three days ago.

I’ve tried fixing it. Chamomile tea. Lavender pillow spray. A weighted blanket that cost more than I want to admit. Magnesium tablets. One of those white noise apps. (I ocean setting. Then rain. Then “brown noise,” which I still don’t fully understand.)

Some of it helped a bit. Most of it didn’t.

Anyway, here’s what actually made a difference: understanding why my brain wouldn’t switch off. Turns out it’s a nervous system thing, not a willpower thing. Which was a relief, actually—I’d spent years thinking I just wasn’t trying hard enough.

Your brain has a cleaning system (and it only works when you’re asleep)

Here’s something I wish I’d known years ago: sleep isn’t just “rest.” It’s active maintenance.

Dr Matthew Walker, author of Why We Sleep (2017), describes sleep as your brain’s housekeeping shift. While you’re out, your brain activates something called the glymphatic system — essentially a waste removal service that clears out metabolic junk, including proteins associated with Alzheimer’s disease.

In other words, your brain literally washes itself while you sleep.

When I first read this, I stopped thinking of sleep as something I should do and started thinking of it as something my brain genuinely needs to function. It’s not laziness. It’s maintenance. (This reframing helped me stop beating myself up on bad nights, which — ironically — made the bad nights slightly less frequent.)

Why “just relax” is useless advice

If you’ve ever had someone tell you to “just relax and you’ll fall asleep,” you’ll know how spectacularly unhelpful that is. It’s like telling someone having a panic attack to “just calm down.” Thanks, very useful, I’m cured.

The problem is that your nervous system doesn’t take orders from your conscious brain. You can’t decide to relax. You have to signal relaxation to your body — and that takes a bit of know-how.

Dr Stephen Porges, who developed Polyvagal Theory, explains that our nervous system is constantly scanning for safety cues. When it detects threat (even low-level stuff like work stress or too much screen time), it keeps us in a state of alertness that makes sleep genuinely difficult.

For me, this explained why I could be bone-tired and still unable to drift off. My body was stuck in “something might go wrong” mode. It wasn’t a willpower problem. It was a nervous system problem.

What’s actually helped (from someone who’s tried everything)

I’m not going to pretend I’ve cracked the code. I still have rough nights. But here’s what’s made a genuine difference:

The “brain dump” notepad. I keep a cheap notebook next to my bed. When my brain starts composing an important email at 2am, I write it down. Not neatly. Just enough to get it out of my head. Something about externalising the thought lets my brain stop holding onto it.

Temperature matters more than I thought. Research suggests the ideal bedroom temperature for sleep is around 16-18°C — cooler than most people keep their homes. I resisted this for ages (I hate being cold), but adding a warmer doona and dropping the room temperature made a noticeable difference.

The 4-7-8 breathing thing. Breathe in for 4 counts, hold for 7, exhale for 8. I know, I know — breathing boring. But this really does work, because that long exhale activates your parasympathetic nervous system. It’s not magic. It’s biology.

Giving up on “trying” to sleep. This sounds counterintuitive, but the nights I lie there thinking “I MUST fall asleep” are always worse than the nights I think “well, if I’m awake, I’m awake.” There’s research on this — it’s called paradoxical intention — but honestly, I discovered it by accident after enough 3am ceiling-staring sessions.

The permission slip you might need

Still, the fact is that some nights are just going to be bad.

You can do everything “right” — dim the lights, skip the late coffee, do your breathing exercises — and still find yourself wide awake at midnight. Bodies are weird. Stress accumulates. Life happens.

One bad night (or even a string of them) doesn’t mean you’re broken. It doesn’t mean you’re doing something wrong. It might just mean your nervous system needs a bit more support right now.

If sleep problems are persistent and really affecting your life, it’s worth chatting to a GP. But for the rest of us — the occasionally sleepless, the sometimes-anxious, the 3am ceiling-starers — please know you’re not alone in this.

And on the nights when sleep won’t come, be gentle with yourself. Your brain’s just trying to keep you safe, even if its timing is absolutely terrible.
