It's 3am and you can't sleep

What should I do in the next ten minutes?

If you've been lying awake for a while, get out of bed: it's called stimulus control, and it's the most useful rule there is. Go to another room, keep the light low, and breathe for a minute with the exhale longer than the inhale. Go back when you're genuinely sleepy.

1. 1

   Get out of bed

   If it feels like a while has passed — twenty minutes or so, without watching the clock — get up. Anywhere but your bedroom.

2. 2

   Low light, not total darkness

   A small lamp, not the ceiling light. And leave the phone where it is: it's a direct door to their Instagram.

3. 3

   Put the loop on paper

   Three lines of whatever you're thinking. Not to solve it tonight — just so it stops circling.

4. 4

   Go back when you're sleepy

   Heavy eyelids is sleepy; bored isn't. If you go back out of impatience, you'll repeat the whole lap in twenty minutes.

1. Push all the air out through your mouth, all the way to the end.
2. Breathe in through your nose for a count of four.
3. Hold for a count of seven.
4. Breathe out through your mouth, slowly, for a count of eight.
5. Repeat the cycle four times: that's about sixty seconds.

This is the 4-7-8 breath. If holding for seven makes you light-headed, drop the hold: what matters is that the air leaving takes longer than the air coming in. A 2026 systematic review in Sleep Medicine Reviews — nine studies, 457 participants — found that slow breathing before bed improves the sleep people report, though the actigraphy measurements stay inconclusive.

Why do breakups feel worse at night?

It hurts more at night because the three things holding you up during the day disappear at once: the busyness, the people and the light. With nothing taking up your attention, your brain goes back to the one unfinished thing.

• The busyness switched off. Work, study, messages: everything that forced you to look elsewhere has closed until tomorrow.
• The people are gone. Nobody's awake to listen, and the sense that you're the only one shows up.
• The bed is a learned cue. If you slept next to that person for years, lying down there alone is climbing into the reminder.

And there's a loop: sleeping badly leaves you more reactive the next day, and that day arrives at night carrying more. In a study published in Current Biology in 2007, healthy people who went a full night without sleep showed amygdala activation around 60% greater in response to unpleasant images.

Why do I wake up at 4am thinking about my ex?

Waking between three and five is the most common shape of breakup insomnia: in the second half of the night sleep is lighter, there's more REM, and cortisol has already begun rising. Any micro-awakening finds a loaded head waiting.

• Don't look at the time. Seeing 4:12 turns an awakening into a countdown; turning the clock around is a daylight decision.
• Don't grab the phone. You'll check whether they wrote, there'll be nothing, and you'll be more awake than before.
• Don't try hard to fall asleep. Effort is the one thing guaranteed to keep you up.

And here's something that has actually been measured: in a 2023 study, 122 recently separated adults were followed for five months with an actigraph. The more time they spent with their ex-partner, the worse their sleep efficiency was. No contact gets charged to the following night.

How long does breakup insomnia last?

There's no guaranteed timeline, and no honest page will hand you an exact number. What the International Classification of Sleep Disorders did define is the threshold: under three months is short-term insomnia; three or more bad nights a week for three months or longer is chronic.

Be suspicious of pages promising it's over in twenty-one days: nobody has that curve.

What usually changes before the number of hours does is the shape. At the start, bad nights come in a row; then they start coming spaced out: two good, one bad, three good. That alternation is the first sign.

Does taking something to sleep actually help?

Alcohol is the worst option: it puts you under fast and then breaks up the second half of the night, exactly where the awakenings live. On melatonin, the American Academy of Sleep Medicine's 2017 guideline suggests it not be used to treat insomnia in adults.

A 2013 review in Alcoholism: Clinical and Experimental Research pooled the studies in healthy people: at all doses alcohol shortens the time it takes to fall asleep and increases fragmentation in the second half of the night. The glass of wine puts you to sleep at midnight and wakes you at four.

With melatonin the honest answer is an awkward one: that 2017 guideline suggests clinicians not use it for sleep-onset or sleep-maintenance insomnia in adults. It's a weak recommendation and it doesn't say melatonin does harm; it says the evidence isn't strong enough.
