If you’re lying in bed unable to sleep, the single most effective thing you can do right now is get out of bed. It sounds counterintuitive, but staying in bed while awake trains your brain to associate the bed with frustration and wakefulness. Go to another room, do something quiet and relaxing, and return only when you feel genuinely sleepy. Below are both immediate techniques to try tonight and longer-term habits that prevent this from happening again.
Get Out of Bed
Sleep specialists at the University of Pennsylvania recommend a simple rule: if you realize you’re lying awake and feeling frustrated about it, leave the bedroom. Don’t watch the clock or try to estimate whether it’s been 10 or 20 minutes. The signal is the frustration itself. Go to a different room, keep the lights dim, and do something low-key until you feel drowsy. Reading with a small lamp or watching TV from a distance are both fine. Avoid your computer or phone, because screens held close to your face emit more light than most people realize, and the activities tend to be mentally stimulating.
When drowsiness hits, go back to bed. If you lie down and the wakefulness returns, get up again. Repeat as many times as needed. This approach, called stimulus control, is one of the core techniques used in clinical insomnia treatment, and it works because it rebuilds the mental link between your bed and sleep rather than your bed and staring at the ceiling.
Try a Physical Relaxation Technique
Your body holds tension you may not notice. Progressive muscle relaxation is a structured way to release it: starting at your feet, curl your toes and arch your feet, hold the tension briefly, then let them go completely. Move upward through your calves, thighs, lower back, abdomen, shoulders, hands, jaw, and forehead. Tense each area for a few seconds, then release. The contrast between tension and relaxation helps your nervous system shift gears.
A simpler version, sometimes called the military sleep method, was reportedly developed for pilots who needed to fall asleep under stressful conditions. Lie on your back with your eyes closed, then mentally scan from your forehead down to your toes, consciously giving each body part permission to relax. Pair this with slow breathing and a mental image of a calm place, focusing on details like sounds, textures, and temperature. If your mind wanders, bring it back to the scene without judging yourself for drifting.
Use Your Breathing to Trigger Relaxation
Slow, deliberate breathing activates your parasympathetic nervous system, which is the branch responsible for calming you down. One popular pattern is 4-7-8 breathing: inhale through your nose for four counts, hold for seven counts, and exhale slowly through your mouth for eight counts. The extended exhale is the key part. It signals your body to lower your heart rate and relax your muscles. Three or four cycles is usually enough to feel a noticeable shift.
Scramble Your Thoughts
Racing or repetitive thoughts are one of the most common reasons people can’t fall asleep. A technique called the cognitive shuffle is designed to interrupt those loops by replacing them with random, meaningless images. Pick a neutral word with at least five letters, like “GARDEN.” For each letter, think of as many words as you can that start with that letter, and briefly picture each one. G: guitar, giraffe, grape, gate. A: airplane, acorn, anchor. The images should be random and unrelated.
This works for two reasons. It occupies your thinking mind just enough to block anxious or planning thoughts, and the random, disconnected imagery mimics the kind of fragmented thinking your brain produces as it drifts toward sleep. Many people don’t make it past the second or third letter.
Room Temperature Matters More Than You Think
Your body needs to cool down slightly to fall asleep. If your bedroom is too warm, this process stalls. Sleep specialists recommend keeping your room between 60 and 67°F (15 to 19°C). That range feels cool to most people, which is the point. If adjusting the thermostat isn’t an option, try lighter bedding, a fan, or sleeping without socks to let heat escape through your feet.
What You Did Earlier Today Might Be the Problem
Sometimes the reason you can’t sleep tonight has nothing to do with what’s happening right now. Two of the most common culprits are caffeine and alcohol, both of which interfere with sleep in ways people consistently underestimate.
Caffeine consumed even six hours before bedtime can cut your total sleep by more than an hour. A study from the American Academy of Sleep Medicine found that 400 mg of caffeine (roughly two to three cups of coffee) taken at 5 p.m. still significantly disrupted sleep at 11 p.m. The general guideline is to stop all caffeine after early afternoon. This includes tea, energy drinks, and chocolate.
Alcohol is trickier because it genuinely helps you fall asleep faster, which makes it feel helpful. But during the second half of the night, once your body has metabolized the alcohol, sleep fragments. You wake up more often, cycle through sleep stages poorly, and lose the deep, restorative phases of sleep. The drowsiness you feel after a drink is real, but the quality of sleep that follows is not.
Dim the Lights Before Bed
Your brain uses light as its primary signal for whether it’s time to be awake or asleep. Blue light, the wavelength most common in screens and LED bulbs, is especially powerful at suppressing melatonin, the hormone that makes you feel sleepy. Research published in the Journal of Applied Physiology found that even relatively low levels of blue light (around 19 lux, which is dimmer than a typical desk lamp) can measurably suppress melatonin production.
In practical terms, this means that scrolling your phone in bed or sitting in a brightly lit room right before trying to sleep actively delays your body’s readiness for sleep. Dimming lights in the hour or two before bed, using warm-toned bulbs, and putting screens away gives your melatonin a chance to rise naturally.
Supplements That May Help
Magnesium is one of the more evidence-backed options for sleep support. It helps activate the “rest and digest” branch of your nervous system and supports the brain chemical responsible for calming neural activity. The glycinate form is commonly recommended because it’s gentle on the stomach. A typical starting dose is 100 to 200 mg of elemental magnesium taken one to two hours before bed. It’s not a sedative, so don’t expect it to knock you out. It’s more of a background support that makes it easier for your body to wind down.
When Sleeplessness Becomes a Pattern
A bad night here and there is normal. But if you’re struggling to fall or stay asleep at least three nights per week, and this has been going on for three months or longer, that meets the clinical definition of insomnia disorder. At that point, the most effective treatment isn’t medication. It’s a structured program called cognitive behavioral therapy for insomnia (CBT-I), which combines many of the techniques described above into a guided plan. It’s typically completed in four to eight sessions and has strong evidence behind it. Your primary care provider can refer you, and online programs also exist.
One rule that helps prevent occasional sleeplessness from becoming chronic: wake up at the same time every morning regardless of how the night went, and don’t nap during the day. This builds up enough sleep pressure that the following night is almost always better. It feels rough in the moment, but it’s one of the fastest ways to reset a disrupted sleep pattern.
