What to Do If You Can’t Go to Sleep Tonight

If you are staring at the ceiling right now, the single most effective thing you can do is stop trying to force sleep. Get out of bed, go to a dimly lit room, and do something quiet and boring until you feel genuinely drowsy. This counterintuitive move is backed by decades of clinical research on insomnia, and it works far better than lying there willing yourself unconscious. The rest of this article covers the specific techniques, environmental tweaks, and mental tricks that can help you fall asleep tonight, along with what to avoid and how to handle the next day if sleep never comes.

Get Out of Bed

The technique behind “get up when you can’t sleep” is called stimulus control, and it is one of the most studied components of cognitive behavioral therapy for insomnia. The core idea is simple: your bed should be strongly associated with sleeping, not with lying awake frustrated. When you stay in bed tossing and turning, your brain starts linking the bed with wakefulness and anxiety rather than rest. A systematic review and meta-analysis found that stimulus control produces meaningful improvements in how long it takes to fall asleep and total sleep time compared with doing nothing.¹

The practical version is sometimes called the “quarter-of-an-hour rule”: if you have been in bed for roughly fifteen minutes and you are not asleep, get up. Go to another room if possible. Do something low-stimulation, like reading a physical book, folding laundry, or listening to a calm podcast. Return to bed only when you feel sleepy. A randomized controlled trial testing this single instruction found that both versions of the rule (leaving the bedroom or staying in the bedroom but getting out of bed) reduced the time it took to fall asleep and the time spent awake during the night.² If leaving the room is not feasible, just sitting up in a chair with the lights low is better than lying in bed stewing. The key instruction, and the one that research suggests matters most, is not to stay in bed awake.³

Stop Watching the Clock

Checking the time is one of the worst things you can do when you cannot fall asleep, and almost everyone does it. Seeing that it is 2:14 AM immediately triggers a cascade of mental math: “If I fall asleep right now I will only get four hours,” “I have to be up in three hours,” “I’m going to be a wreck tomorrow.” A study of insomnia patients found that this clock-watching behavior commonly leads to frustration and actively perpetuates insomnia symptoms.⁴

Experimental research has shown exactly how destructive this habit is. When people with insomnia were assigned to monitor a clock while trying to fall asleep, they experienced more pre-sleep worry and reported taking longer to fall asleep. They also overestimated how long they had been lying awake compared to a control group given a non-clock monitoring task.⁵ The fix is blunt: turn your clock around, put your phone face-down in another room, or cover any visible time display. You do not need to know what time it is. Knowing will not help you sleep faster, and the evidence says it will make things worse.

Put Your Phone Away

You have probably heard that screens are bad before bed, but the specifics matter for tonight. The issue is not screens in general but the type of light they emit. Blue-wavelength light, which peaks between about 446 and 477 nanometers, is the most potent suppressor of melatonin, the hormone that signals your body it is time to sleep. Blue LED light suppresses melatonin in a dose-dependent way, meaning the brighter the screen and the longer the exposure, the worse the effect.⁶

A study comparing red and blue LED light in healthy adults found that after two hours, blue light kept melatonin suppressed at about 7.5 pg/mL while red light allowed melatonin to recover to 26.0 pg/mL.⁷ That is a large gap. Research on tablets specifically found that melatonin suppression from screen use reaches significance after about two hours of exposure, though some suppression begins after one hour when a blue light component is present.⁸

If you are reading this on your phone right now, that is fine, but switch to the dimmest setting and enable any “night shift” or warm-color filter your device offers. These reduce but do not eliminate the blue component. Better yet, finish reading, put the phone in a drawer, and switch to a paper book or an audio source. If you must use a screen, keep it brief and dim.

Cool Your Body Down

Falling asleep is closely tied to a drop in core body temperature. Your body facilitates this by dilating blood vessels in your hands and feet, pushing warm blood to the skin surface where heat can escape. Research has shown that this temperature gradient between your core and your extremities is actually the strongest predictor of how quickly you fall asleep, outperforming even subjective sleepiness ratings or melatonin onset timing.⁹

This explains the warm bath trick that gets repeated in sleep advice columns: a warm bath or shower about an hour before bed heats your skin surface and opens up blood vessels. When you step out, those dilated vessels dump heat rapidly, your core temperature drops, and you feel sleepy. If a full bath is not practical tonight, even soaking your feet in warm water for ten minutes may help. Keep your bedroom cool, ideally somewhere around 65 to 68°F (18 to 20°C). A room that is too warm interferes with this natural heat-loss process and makes it harder for your body to reach the temperature dip it needs to initiate sleep.

Mental Techniques Worth Trying Tonight

When your mind is racing, you need something to redirect it. Two approaches have research behind them, and both are free and can be done lying in bed.

The first is called the cognitive shuffle. The idea, developed by a cognitive scientist, involves deliberately generating a random sequence of unrelated mental images: a dog, a stapler, a beach ball, a doorknob, a slice of pie. You cycle through them without trying to create a narrative or make connections. The theory is that this kind of fragmented, diverse imagining mimics the pattern of thought that naturally occurs as you drift off, and it prevents your mind from constructing the coherent anxious narratives that keep you awake.¹⁰ Many people who try it report that they rarely make it past a few minutes before drifting off, though the formal evidence base is still developing.

The second technique is paradoxical intention. Instead of trying to fall asleep, you try to stay awake. Lie in bed with your eyes open in a dark room and gently challenge yourself to remain conscious. This sounds absurd, but it works by short-circuiting the performance anxiety that comes from trying to sleep. A review of the evidence found that paradoxical intention improved sleep onset latency, reduced difficulty falling asleep, and decreased the number of nighttime awakenings compared to doing nothing.¹¹ The attitude matters: it should feel light and almost playful, not like another pressured task. You are not “working” at staying awake. You are just letting go of the demand that you must sleep.

Breathing Exercises

Slow, deep breathing is one of the fastest ways to shift your nervous system toward relaxation. Diaphragmatic breathing, where you breathe deeply into your belly rather than shallowly into your chest, has been shown to lower cortisol levels, reduce heart rate, and improve sleep quality scores in a randomized controlled trial.¹² You do not need a specific count or branded method. The general principle is to slow your exhale so it is longer than your inhale. Breathe in through your nose for a few seconds, then breathe out slowly through your mouth or nose for a few seconds longer. Focus your attention on the physical sensation of the breath moving in and out. If your mind wanders, bring it back to the breath. Even five to ten minutes of this can noticeably reduce the wired, alert feeling that keeps you up.

What to Eat and Drink (and Not) Tonight

If you are hungry at midnight and thinking about a snack, keep it small and simple. A study of healthy young men found that eating a slowly digested, high-protein meal late at night disturbed sleep, while a lighter, more easily digested meal had less impact.¹³ A handful of crackers, a small banana, or a glass of milk is fine. A large plate of steak, a spicy burrito, or anything that is going to take hours to digest is not. Your body has to do real metabolic work to process a heavy meal, and that work competes with the wind-down process sleep requires.

Alcohol deserves its own mention because it is the most common self-prescribed sleep aid and one of the worst. A drink or two may make you feel drowsy and can genuinely reduce the time it takes to fall asleep initially. But alcohol fragments the second half of the night. Once your body metabolizes the alcohol, sleep quality deteriorates substantially.¹⁴ You are more likely to wake up at 3 or 4 AM, and the sleep you get after that point is lighter and less restorative. If you have already had a drink tonight, you cannot undo it, but do not reach for another one thinking it will help.

Caffeine is obvious but worth quantifying: its half-life in most adults is roughly five to six hours, which means half the caffeine from that afternoon coffee is still circulating. If you had coffee after 2 PM, it is plausibly still affecting you. There is nothing you can do about that tonight, but it is worth noting for tomorrow.

Over-the-Counter Sleep Aids

If you are considering raiding your medicine cabinet, it helps to know what actually works. The most commonly available options are antihistamines (like diphenhydramine, sold as Benadryl or in products like ZzzQuil), melatonin, and valerian root.

A systematic review of these three over-the-counter options found that melatonin showed the most consistent benefits, particularly in prolonged-release formulations and among older adults with diagnosed insomnia. The clinical trial data for diphenhydramine and valerian, by contrast, suggested limited effects.¹⁵ A separate meta-analysis found that exogenous melatonin was most effective for reducing sleep onset latency, meaning it helps you fall asleep faster rather than keeping you asleep longer.¹⁶

A few practical notes for tonight: melatonin works best when taken one to two hours before your desired bedtime, at a low dose (0.5 to 3 mg). Most store-bought melatonin comes in 5 or 10 mg tablets, which is far more than the evidence suggests you need. If that is all you have, you can break a tablet. Diphenhydramine will make you drowsy, but it tends to cause grogginess the next morning and can impair alertness for hours after waking. Overall, the evidence for non-prescription sleep aids is mixed at best.¹⁵ None of these are a reliable fix for tonight, but melatonin is the safest bet if you have some on hand.

Sound and Your Sleeping Environment

If noise is part of your problem tonight, you have a few options. The popular solution is a white or pink noise machine or app, but the evidence for sound masking is actually weaker than the evidence for simple earplugs. A controlled study exposing participants to intermittent environmental noise (the kind of unpredictable noise that wakes people up, like traffic or a partner’s snoring) found that earplugs were the only intervention that fully preserved deep sleep and REM sleep. Pink noise at two different volume levels did not significantly protect sleep structure compared to noise alone.¹⁷ Participants wearing earplugs spent about 21 more minutes in deep and REM sleep per night than those exposed to noise without protection.

This does not mean noise machines are useless. They can be psychologically comforting and may help mask very low-level background sounds. But if your environment is genuinely noisy, a pair of foam earplugs is the more evidence-supported choice. If you do not have earplugs, a fan provides both white noise and airflow that helps with room temperature.

Getting Through Tomorrow

If you have read this far and sleep still has not come, it is worth thinking about damage control for the day ahead. The good news is that one bad night is less catastrophic than it feels at 3 AM. A study testing cognitive performance after a single night of sleep deprivation found no significant decline in scores on standard cognitive tests.¹⁸ You will feel tired and irritable, but you are likely to function better than your anxious 2 AM self is predicting.

A nap the next day can meaningfully help. Research on recovery from acute sleep restriction found that a midday nap reversed increased sleepiness and normalized stress-related immune markers, including returning elevated cortisol levels to baseline immediately after the nap.¹⁹ Keep a recovery nap short, roughly 20 to 30 minutes, and take it before mid-afternoon. A long, late nap will feel restorative in the moment but can push back your sleep drive enough to set up another bad night, starting the cycle over.

Caffeine is an obvious tool, and it works. Use it strategically: have it in the morning, and cut yourself off by early afternoon to avoid carrying the stimulant into the following night. Avoid the temptation to over-caffeinate. Two cups of coffee will sharpen you; six will make you jittery and anxious without proportionally improving alertness.

When a Bad Night Becomes a Pattern

One sleepless night is unpleasant but normal. Most adults experience occasional insomnia triggered by stress, schedule changes, or illness. The concern is when acute sleeplessness hardens into a chronic pattern, and the research on how that happens is informative.

The most widely used model in sleep medicine describes three phases. A predisposing factor, like a naturally anxious temperament, makes some people more vulnerable. A precipitating event, like a work crisis or a breakup, pushes them over the threshold into acute insomnia. Then perpetuating factors take over. These are the compensating behaviors people adopt to cope: spending extra hours in bed, napping excessively, scrolling their phone in bed, drinking more coffee, and developing catastrophic thoughts about sleep (“I’ll never sleep normally again”).²⁰ Over time, the original stressor fades, but the perpetuating habits keep the insomnia alive on their own.²¹

If you have been struggling to sleep for more than a few weeks, and especially if you recognize yourself in those perpetuating behaviors, it is worth talking to a doctor about cognitive behavioral therapy for insomnia (CBT-I). This is the first-line treatment recommended by every major sleep organization, and it is more effective than sleeping pills for long-term outcomes. It can be delivered in person, through telehealth, or even through validated self-guided apps. The techniques in this article, particularly stimulus control, clock avoidance, and paradoxical intention, are all components of CBT-I, so if they help tonight, a full course of the therapy is likely to help more.

Why You Feel Awake When You Should Be Tired

It can feel baffling to be exhausted all day and then wide awake the moment your head hits the pillow. This is not your imagination. Insomnia researchers describe this as hyperarousal: a state where the body’s alert systems stay activated even when external circumstances call for rest. A review of the evidence found that this hyperarousal involves neuroendocrine pathways, meaning stress hormones and related signaling systems remain elevated.²² Your cortisol may be running higher than it should at night, and your brain’s arousal centers are not quieting down on schedule.

Adding to the frustration, people with insomnia frequently underestimate how much sleep they actually got. Research into sleep state misperception suggests that insomnia involves a dysfunction in the brain’s ability to distinguish between being asleep and being awake.²³ You may have slept for stretches that felt like wakefulness. This is not meant to dismiss your experience; feeling like you did not sleep is miserable regardless of what a lab would show. But it is worth knowing that the reality is probably not as dire as the feeling suggests. That knowledge alone can take some of the edge off the panic, and less panic means an easier time drifting off.
