Why You Can't Sleep (And What to Do About It Tonight)

The night I couldn't sleep for the hundredth time

I remember lying awake at 2am, completely exhausted, unable to switch off, adding "fix sleep" to a mental to-do list that was itself keeping me awake.

If that sounds familiar, you're not alone. Sleep problems affect roughly a third of adults, and the number rises sharply among women in their thirties and forties. Yet most of the advice on the internet amounts to "go to bed earlier" and "put your phone down" — which is not exactly revelatory.

Here's what I've learned from working through it myself and supporting dozens of clients through the same.

Why your brain won't stop at night

The racing mind at bedtime isn't a flaw in your thinking. It's a consequence of how modern life is structured.

We spend our days in high-stimulation, high-demand environments — screens, decisions, deadlines, noise — and then expect our nervous system to flip a switch at 10pm. It can't. Not without help.

Your brain needs a transition. A buffer zone between the demands of the day and the rest of the night. Most people don't build one, and they pay for it in the ceiling.

The sleep hygiene advice you've already heard (and why it's not enough)

Yes, consistent sleep and wake times matter. Yes, your bedroom should be cool and dark. Yes, caffeine after 2pm is probably not helping.

But if you're lying awake with a busy mind, those things alone won't fix it. What you also need is:

A genuine wind-down. Not scrolling. Not half-watching TV while thinking about tomorrow. A real transition — something that signals to your nervous system that the day is over. This could be reading fiction, a slow walk, gentle stretching, a bath, or simply sitting quietly with a cup of herbal tea.

An externalising practice. The brain's job is to keep track of unfinished things. That's why your mind replays tomorrow's meeting at midnight. Writing things down — a brief brain dump before bed — signals to your brain that it doesn't need to hold on. It's been recorded. It can let go.

A body-first approach. Sleep is a physical state, not just a mental one. Slowing your breathing, releasing tension in your body, and lowering your heart rate through deliberate relaxation is often more effective than trying to think your way to sleep.

The one change that moved the needle most for me

Of everything I've tried, the single most impactful habit was a consistent wind-down that started 45 minutes before I wanted to be asleep — not the moment I got into bed.

No screens. Low light. Something quiet. The same routine, night after night.

It felt pointless for the first week. By week three, my body had started associating the sequence with sleep. By week six, I was falling asleep faster than I had in years.

Consistency is the mechanism. The specific routine matters far less than doing something, every night, that your body learns to recognise as the signal to rest.

If it's been going on for a long time

Chronic insomnia — difficulty sleeping three or more nights a week for more than three months — often has roots that go beyond sleep hygiene. Hormonal changes, anxiety, chronic stress, and certain nutritional deficiencies can all disrupt sleep in ways that require a more targeted approach.

If you've been struggling for a long time and the basics aren't working, it's worth going deeper. That's exactly the kind of work we do in the Sleep & Energy Reset programme — looking at the whole picture, not just the symptom.
