Can't Sleep: What to Do Tonight and What to Do Long-Term

1:38 am. You are reading this on your phone, in bed, with one eye closed. I know because that is exactly the circumstances under which most people arrive at this page. And I know what you are looking for: something that will work tonight.

I have a tonight answer and a real answer. They are different, and neither of them is “try harder to sleep.”

What to do right now

If you have been lying awake for roughly twenty minutes, get out of bed. I know. It sounds wrong. It feels wrong. You are tired, the bed is warm, and the rest of the apartment is cold and dark and uninviting. But lying awake in bed is the single most counterproductive thing you can do for your insomnia, and getting up is the single most evidence-supported move available to you right now [1].

Go to a different room. Keep the lights dim. Do something low-stimulation: read a physical book, listen to a podcast at low volume, sit with a cup of decaf. Do not check the clock, do not scroll your phone, do not calculate how much sleep you can still get. When you feel genuinely sleepy, not just tired, but that heavy-eyed, drifting sensation, go back to bed.

If you wake up again and stay awake for twenty minutes, repeat the process. It may feel absurd. The third time you walk to the living room at 4am, it will feel like performance art. It is stimulus control, one of the most effective components of CBT-I, and it has been studied since Richard Bootzin first described it in 1972 [1].

The logic: your brain has paired the bed with wakefulness. Every night you spend lying awake strengthens that pairing. Getting up breaks it. Over days and weeks, the bed becomes a cue for sleep again rather than a cue for the ceiling and the catastrophic math about tomorrow.

What not to do right now

Do not check the time. Clock-watching is a monitoring behavior that increases arousal. Harvey’s cognitive model shows that monitoring your sleep, whether by checking the clock, counting hours remaining, or calculating wake time, keeps the anxious brain engaged exactly when disengagement is needed [2]. Turn the clock away from the bed. If you are using your phone as an alarm, put it face down across the room.

I kept a digital clock on my nightstand for years. It was the first thing I looked at every time I woke up, and within two seconds of seeing the number I was doing the arithmetic: how much sleep I had gotten, how much I could still get, whether the remaining hours were worth the effort. Every calculation was a dose of adrenaline. Removing the clock from the bedroom was one of the smallest and most effective changes I made.

Do not reach for a supplement. Nothing you take at 1am will produce meaningful sleep tonight. Melatonin affects sleep onset timing through circadian mechanisms; it is not a sedative you can deploy mid-wake. A glass of something alcoholic will sedate you but fragment the remaining sleep cycles and suppress REM. The only acute intervention with evidence for this moment is getting out of bed.

Do not catastrophize. “If I don’t sleep tonight I won’t function tomorrow” is the prediction that fuels the loop. It feels true. It is almost always an overestimate. You have functioned after bad nights before. You will function tomorrow, less well than you would like, and better than the 1am prediction claims. The prediction is a threat signal, and threat signals keep the brain alert. Noticing that you are making the prediction is not the same as being able to stop it, but it is the first step toward weakening it.

Why “can’t sleep” becomes chronic

A single bad night is not insomnia. It is a normal human experience caused by stress, travel, illness, caffeine timing, or nothing identifiable at all. Insomnia becomes chronic when the response to the bad night creates the conditions for the next one.

The pathway looks like this: you sleep badly, so you go to bed earlier the next night to compensate. You lie awake longer, because the extra time in bed dilutes your sleep pressure. You start worrying about sleep during the day. You begin avoiding commitments in case you are too tired. You try a supplement. You try another supplement. Each adaptation is sensible and each one teaches the brain that sleep is a problem requiring management [2].

This is Harvey’s cognitive model in action. The monitoring behaviors (clock-checking, tracking how you feel for signs of tiredness), the safety behaviors (canceling plans, going to bed early, napping), and the catastrophic beliefs (one bad night will ruin tomorrow) form a self-reinforcing system. The system maintains insomnia independently of whatever caused the first bad night. The original trigger may be long gone; the cycle sustains itself.

My own trigger was a stressful project at work. When the project ended, the stress ended with it. The insomnia did not. By then it had its own infrastructure: the early bedtime, the supplements on the nightstand, the weekend naps, the careful mental accounting of how I felt every afternoon. The project was over. The monitoring and compensating and worrying about sleep had become the thing keeping me awake. That is the mechanism. The trigger lights the fire, and the perpetuating behaviors supply the fuel.

The diagnostic threshold is specific: difficulty sleeping at least three nights per week for three months or longer, with associated daytime impairment [3]. If that describes you, the problem is not tonight. The problem is the cycle, and the cycle has a treatment.

The long-term answer

CBT-I addresses chronic insomnia through the mechanisms that maintain it. The full program includes sleep restriction (building sleep pressure by reducing time in bed), stimulus control (breaking the bed-wakefulness association), cognitive restructuring (targeting the catastrophic predictions), and sleep hygiene (the genuine version, not the listicle version) [5].

The AASM clinical practice guideline strongly recommends multicomponent CBT-I as the first-line treatment for chronic insomnia in adults [5]. The evidence base includes multiple meta-analyses showing durable improvements in sleep onset latency, wake after sleep onset, and sleep efficiency. The improvements persist after treatment ends, which is something medication cannot claim.

Sleep restriction is the most effective single component and the least intuitive. It asks you to spend less time in bed, not more. If you are sleeping five and a half hours in an eight-hour window, your time-in-bed allowance starts at five and a half hours. The first week is hard. The consolidation of sleep into a shorter, denser window is what restores the bed as a cue for sleep rather than wakefulness.

This is not a tonight fix. It is a weeks-long program that changes your relationship with sleep. The tonight fix, stimulus control, is the first step of the same program. What you are doing right now, getting out of bed when you cannot sleep, is the beginning of the treatment whether you know it or not.

What makes this hard

The hard part is that you are tired and everything in this post asks you to do more, not less. Get out of bed. Do not check the clock. Start a program that takes weeks. You wanted a breathing exercise that would put you under in ninety seconds, and I am offering you a behavioral intervention that will require effort for a month.

I know. I wanted the breathing exercise too. I tried several. I tried 4-7-8 breathing, box breathing, progressive muscle relaxation done in bed against all recommendations. They work the way a single aspirin works for a broken leg: they address a symptom and leave the structure unchanged. On occasion they helped me fall asleep; they never fixed the insomnia.

What I can tell you, from the far side of two uncomfortable weeks of sleep restriction and many nights of getting up and sitting in a cold living room at 3am with a book I did not want to read, is that the program works for most people. Not all people, and not immediately. But durably, and without a dependency risk, and in a way that a pill cannot match over the long term.

The other hard part is that this post is a poor substitute for a therapist. A trained CBT-I clinician adjusts the protocol to your specific pattern, answers your questions when the second week gets discouraging, and catches the things that a general post cannot address. If you have access to one, use one. If you do not, a digital CBT-I program provides the structure and tracking that self-management alone sometimes lacks.

For tonight: get out of bed. Go sit somewhere dim and quiet and do something that requires very little from you. When the heavy-eyed feeling arrives, and it will, go back to bed and let it happen. For tomorrow: consider starting a sleep diary. The diary is where the real work begins, because it replaces the feeling of how you slept with something closer to the fact of how you slept, and the gap between those two things is wider than most people expect.

If your sleep is affecting daily life, talking to a GP or sleep specialist is a good first step. The American Academy of Sleep Medicine has a provider finder at sleepeducation.org. If insomnia is accompanied by depression, anxiety or other concerns, those are worth raising with your doctor as part of the same conversation.
