Can't Sleep Because of Anxiety? What to Do Tonight

When anxiety keeps you awake, the problem is a racing, aroused mind — so the fix is lowering arousal, not trying harder to sleep. Get out of bed if you are wired, use slow breathing (4-7-8 or box breathing), write worries down earlier in the evening, and keep a fixed wake time. CBT-I directly targets the anxiety-insomnia loop.

It's late, you're exhausted, and your mind has chosen this exact moment to replay every worry you own. Anxiety-driven insomnia is one of the most common and most frustrating sleep problems there is, because the harder you try to sleep, the more awake you feel.

Here's what actually helps, tonight and beyond.

Tonight: stop trying to sleep

This sounds backwards, but it's the most important rule. Lying in bed willing yourself to sleep raises your arousal and trains your brain to associate the bed with frustration. If you've been awake for around 20 minutes and you're wired, get up. Go to another room, keep the lights low, do something calm and boring, and only return to bed when you feel sleepy. Protect the bed as a place for sleep, not for battling your thoughts.

Get the worries out of your head

Racing thoughts loop because your brain is afraid it'll forget them. Give it permission to let go: keep a pad by the bed and write down what's spinning — worries, tomorrow's to-dos, the lot. A worry dump before bed, or in the moment, externalises the loop so your mind can stand down.

Slow your body down

Anxiety is physical as much as mental. A long, slow exhale tells your nervous system it's safe. Try breathing in for four counts and out for six to eight, for a few minutes. Slowing the out-breath is the part that matters — it nudges you out of fight-or-flight.

The longer-term fix

One bad night is normal. Weeks of them is a pattern worth treating — and the good news is that chronic insomnia has a genuinely effective, drug-free treatment: CBT-I (Cognitive Behavioural Therapy for Insomnia). It's what sleep clinics use first, and it directly targets the anxiety-and-effort loop that keeps you awake. Our guide on what CBT-I is explains it in plain English.

Anxious and can't sleep — is that just anxiety, or insomnia too?

Usually both, feeding each other. Anxiety raises your heart rate and keeps your mind scanning for threats, which blocks sleep onset; the resulting bad night then makes you anxious about sleep itself the next evening. Treating only the anxiety often isn't enough once that second loop has taken hold — which is exactly what CBT-I is built to break.

Can't fall asleep because of anxiety — what actually stops the racing thoughts?

Externalise them rather than trying to out-argue them in your head. Write down what's spinning on a pad by the bed, then pair it with slow breathing — a longer exhale than inhale is what actually shifts your body out of fight-or-flight, not the content of the thoughts themselves.
