If you can’t fall asleep, the single most effective thing you can do right now is get out of bed. It sounds counterintuitive, but lying awake in bed trains your brain to associate the bed with frustration rather than sleep. Give yourself roughly 20 minutes. If you’re still awake and starting to feel restless, move to another room and do something quiet until you feel genuinely drowsy, then return to bed.
That 20-minute guideline is the foundation of stimulus control therapy, one of the most well-supported techniques in sleep medicine. The rest of this article covers what to do during those wakeful minutes, what’s keeping you up in the first place, and how to set yourself up for better sleep going forward.
What to Do When You Leave the Bed
The goal is to lower your alertness, not entertain yourself. Good options include listening to calm music, reading a physical book (not on a bright screen), or doing a simple meditation. Avoid eating, working, scrolling your phone, or watching anything exciting on TV. These activities spike your alertness and push sleep further away.
If you wake up in the middle of the night and can’t fall back asleep within about 20 minutes, the same rule applies: get up, do something boring and low-stimulation, and only return to bed when your eyelids feel heavy. You may need to repeat this cycle more than once. That’s normal, especially at first.
A Breathing Technique That Actually Works
The 4-7-8 breathing method is worth trying, both while you’re in bed and during your quiet time out of bed. It works by activating your body’s “rest and digest” nervous system, which counteracts the stress response that keeps your heart rate up and your thoughts racing. Studies show it lowers heart rate and blood pressure, putting your body in the right physical state for sleep.
Here’s how to do it:
- Step 1: Place the tip of your tongue against the back of your upper front teeth. Keep it there the whole time.
- Step 2: Exhale completely through your mouth.
- Step 3: Inhale quietly through your nose for 4 counts.
- Step 4: Hold your breath for 7 counts.
- Step 5: Exhale slowly through your mouth for 8 counts.
- Step 6: Repeat the cycle three more times (four total).
The counting sequence doubles as a mental anchor. Instead of looping through tomorrow’s to-do list or replaying an awkward conversation, your mind latches onto the numbers. It’s a distraction with a physiological payoff.
Your Bedroom Might Be Working Against You
Temperature matters more than most people realize. The Cleveland Clinic recommends keeping your bedroom between 60 and 67°F (15 to 19°C). Your core body temperature naturally drops as you fall asleep, and a cool room helps that process along. If you’re waking up sweaty or kicking off blankets, your room is too warm.
Light is the other major factor. Your brain uses light, especially blue-wavelength light around 464 nanometers, to decide whether it’s daytime. In one study, melatonin levels after two hours of blue light exposure were just 7.5 pg/mL compared to 26.0 pg/mL under red light. That’s a dramatic suppression. Current guidelines recommend keeping light levels in the three hours before bedtime extremely low. In practical terms, this means dimming overhead lights in the evening, using warm-toned bulbs, and turning on night mode on any screens you use.
Caffeine, Alcohol, and Screens Before Bed
Caffeine has a long and variable half-life, meaning the cup of coffee you had at 3 p.m. could still be circulating in meaningful amounts at bedtime. Research supports cutting off caffeine at least six hours before bed, though some people metabolize it more slowly and may need a longer buffer. If you’re sensitive to caffeine, noon is a safer cutoff.
Alcohol is trickier because it genuinely helps you fall asleep faster. The problem is what happens next. At moderate and high doses, alcohol significantly delays the onset of your first REM sleep period and reduces the total percentage of REM sleep across the night. It also consolidates the first half of sleep while fragmenting the second half, which is why you might fall asleep easily after a few drinks but wake up at 3 a.m. feeling wired. Even low doses disrupt the second half of the night.
Screens combine two problems: blue light that suppresses melatonin (covered above) and content that keeps your brain engaged. If you use your phone in bed, your brain starts associating the bed with scrolling rather than sleeping. Ideally, screens go off 30 to 60 minutes before you intend to sleep.
Morning Sunlight Resets Your Internal Clock
What you do in the morning affects how easily you fall asleep at night. A study published in BMC Public Health found that every 30 minutes of sunlight exposure before 10 a.m. shifted sleep timing earlier by about 23 minutes and improved overall sleep quality scores. Sunlight in the morning signals your brain to start the countdown toward producing melatonin later in the evening.
You don’t need to sit outside for an hour. Even a short walk, having coffee by a window, or commuting without sunglasses can make a difference. The key is consistency: regular morning light exposure gradually pulls your circadian rhythm into a more predictable pattern, making it easier to feel sleepy at the right time.
Supplements That May Help
Melatonin is the most widely used sleep supplement, but most people take it incorrectly. A dose-response meta-analysis found that melatonin’s sleep benefits peak at around 4 mg per day, and that taking it three hours before your desired bedtime works better than the common practice of taking it 30 minutes before bed. Melatonin shortens the time it takes to fall asleep and increases total sleep time, but it’s not a sedative. It signals to your brain that it’s nighttime. If your room is brightly lit, that signal gets overridden.
Magnesium is another option with a plausible mechanism. It interacts with the brain’s calming neurotransmitter system (GABA) while simultaneously dampening excitatory signals. This dual action has a particular impact on deep, slow-wave sleep, the phase most important for physical restoration and memory consolidation. Magnesium glycinate is the form most commonly recommended for sleep because it’s well absorbed and less likely to cause digestive issues than other forms.
When Sleeplessness Becomes a Bigger Problem
Everyone has bad nights. But if you’re struggling to sleep at least three nights per week and this has been going on for three months or longer, that meets the diagnostic threshold for chronic insomnia disorder. At that point, the most effective treatment isn’t medication. It’s cognitive behavioral therapy for insomnia (CBT-I), a structured program that combines the stimulus control techniques described above with sleep restriction, relaxation training, and strategies for managing the anxious thoughts that fuel the cycle.
CBT-I is typically delivered over four to eight sessions, and its effects last longer than sleep medications because it addresses the underlying patterns rather than masking them. Many providers now offer it through telehealth or app-based programs, making it more accessible than it used to be.
