Insomnia: why trying harder backfires
With sleep, effort is the one thing that never helps. Learn how a bed turns into a place your body expects to be awake, the rule that breaks the loop, and what the evidence says to try first.
Chronic insomnia
Trouble falling asleep or staying asleep on at least three nights a week for three months or more, with a cost you can feel in the day: tiredness, poor concentration, low mood. The daytime part matters. Someone who sleeps six hours and feels fine doesn't have insomnia; someone who lies awake for two hours and drags through every day does.
A week of bad nights before an exam or after bad news isn't insomnia. It's a normal response, and it usually fades once the cause does.
THE PARADOX
Effort is the opposite of sleep
Sleep is something your body does when you stop doing things. The moment you start trying (checking whether it's working, calculating the hours left, telling yourself you must sleep because tomorrow matters) you have switched on the system that watches, plans and worries. That's the alerting system, and it is precisely what has to be off.
Nobody falls asleep by concentrating. You fall asleep on the sofa during a boring film, when you weren't trying at all. That's not a coincidence. It's the mechanism.
Check yourself
Shahin has a presentation tomorrow. At 12:30 he's still awake, so he closes his eyes harder, counts backwards, and reminds himself he has to sleep now or the day is ruined. By 2am he's more awake than at midnight. Why?
- Trying to sleep is effort, and effort turns on the alerting system that sleep needs turned off
- He isn't concentrating hard enough, and more focus on falling asleep would get him there
- His body has forgotten how to sleep and will have to learn it again from the beginning
- Counting backwards is the wrong technique for him, and another relaxation method would have worked instead

Trying to sleep is effort, and effort turns on the alerting system that sleep needs turned off
Exactly. Every check of whether it's working is one more act of monitoring, and monitoring is being awake. The way out is to stop trying, which usually means getting out of bed.
THE LOOP
How a bed learns the wrong lesson
Your brain links places to what usually happens in them. Sleep well in your bed for years and the bed itself is a cue: you get in, your body starts letting go. Spend enough hours lying there awake, frustrated and calculating, and the link quietly reverses. Now getting into bed is the cue for alertness. This is called conditioned arousal, and it's why a long-running sleep problem keeps going after the thing that started it is gone.
The giveaway: you're falling asleep on the sofa at 11, you drag yourself to bed, and you're wide awake the moment your head touches the pillow. Or you sleep better in a hotel than at home.
The chair you only ever argue in
Imagine one armchair in your house where, for a year, every difficult phone call happened. Eventually you'd feel your shoulders tighten just sitting in it, without deciding anything. Your bed can learn the same way. Where the analogy breaks: you could throw the chair out, and you can't stop sleeping in your bed. So instead of removing it, you change what happens there until it means sleep again.

Shahin has been lying awake for forty minutes. Getting up and sitting somewhere dim and dull is more likely to help him than staying put with his eyes closed.

True
True. Lying still doesn't do the work of sleep, and every hour spent awake in bed teaches your brain that this is a place for being awake. Get up, go somewhere dim and dull, and come back when you're actually sleepy.
Stimulus control: five rules that retrain the bed
- Bed is for sleep
Sleep and time with your partner, and nothing else. Not work, not the phone, not television, not eating, not lying there planning tomorrow.
- Go to bed only when sleepy
Sleepy means heavy eyes and yawns. Tired is different: tired can sit up until 2am. If you're tired but not sleepy, stay up.
- Awake about 20 minutes? Get up.
Don't time it, that's clock-watching. Judge it. Leave the room, sit somewhere dim, and do something easy and boring. No screens, no bright lights, no big tasks.
- Go back when sleepiness returns
And if it disappears again, get up again. Some nights that's three rounds. That's the treatment working, not failing.
- Same wake time, whatever happened
Get up at your fixed hour even after a terrible night, and skip naps while you're doing this. The extra sleep pressure is what makes tomorrow night easier.

Does it feed the loop or break it?
- Lying there for an hour and a half hoping sleep turns up
- Getting up and reading in a dim room until your eyes go heavy
- Going to bed at 9:30 to give yourself more chances
- Getting up at 6:45 anyway after a terrible night
- Answering work messages in bed on a Saturday afternoon
- Going back to bed only once the sleepiness returns

CBT-I: what the guidelines actually recommend
- For insomnia that has lasted months, CBT-I (cognitive behavioural therapy for insomnia) is what major medical guidelines recommend before sleeping pills. It's short and structured, usually four to eight sessions.
- It contains what you've just read: stimulus control, a fixed wake time, work on the thoughts that keep you up, and relaxation skills.
- It also uses sleep restriction: deliberately shortening your time in bed to concentrate your sleep, then widening it again as it improves. It's effective, but it makes you sleepier before it makes you better, so do it with a professional rather than alone.
- It exists as a therapist-led course and, in many places, as a digital programme. Your doctor is the person to ask about what's available to you.

Azadeh has slept badly four or five nights a week for six months and is exhausted at work. She books an appointment to ask for sleeping tablets. What do the guidelines say should be offered first?
- A herbal supplement, because natural products are safe by definition
- Nothing, since insomnia that has gone on this long always clears up on its own eventually
- More time in bed each night, so that sleep has more opportunity to happen
- A structured course of CBT-I, which is recommended ahead of medication for insomnia this long

A structured course of CBT-I, which is recommended ahead of medication for insomnia this long
Right. For insomnia lasting months, CBT-I is the recommended first-line treatment, because it works on the loop keeping the problem alive and the gains tend to hold. What role medication plays is a conversation for her and her doctor.

Match each one to the idea behind it
Show the answer
- Getting up after about 20 minutes awake → Stimulus control, breaking the bed-and-awake link
- Keeping the 6:45 alarm after a bad night → Protects the sleep pressure you need tonight
- Lying there trying hard to drop off → Sleep effort, which raises alertness
- Wide awake the moment your head hits the pillow → Conditioned arousal, the bed acting as a cue
Lesson recap
- Trying to sleep is effort, and effort is the alerting system doing exactly what sleep needs it not to do.
- Hours spent awake in bed teach your brain that bed means being awake. That's conditioned arousal.
- Stimulus control breaks it: bed only for sleep, go only when sleepy, get up after about 20 minutes awake, same wake time regardless.
- More time in bed and long catch-up naps feel like help and make it worse.
- For insomnia lasting months, CBT-I is the first-line treatment. Take it to your doctor.
