"Can't get back to sleep at 3 a.m.? What to do in the next ten minutes"

You are awake. You are not sure why. The house is quiet, the duvet is half on the floor, and some part of your brain has already started the arithmetic: if I fall asleep right now, that is three hours and forty minutes.

Then it is 3:20, and you are more awake than you were at 3:07.

This post is not about why you woke up. We covered that in why you wake up at 3 a.m. hot. This one is about the part after, the ten minutes that decide whether this is a short blip or the rest of the night. Most of what helps comes down to one idea: stop waking yourself up further.

Waking at 3 a.m. is normal. Staying awake is the part to work on

An unbroken night is mostly a myth. Sleep runs in cycles of roughly 90 minutes, and adults usually go through five or six of them a night. It is normal to surface briefly at the end of each one, and those brief wakes tend to get more frequent as we get older. Most of them you never remember.

So the wake-up itself is not the problem. The problem is what happens in the next few minutes, when a brief surfacing turns into full alertness: you check the time, you notice you are hot, you start thinking about the 9 a.m. meeting, and now your body thinks it is morning.

People have also been awake in the middle of the night for a very long time. The historian Roger Ekirch, of Virginia Tech, spent years in diaries, court records and old literature and found thousands of references to a "first sleep" and a "second sleep," with a stretch of quiet wakefulness in between. People prayed, talked, read, or just lay there. Nobody saw it as an emergency.

That does not mean you have to love it. It means the goal is not "never wake up." It is "get back under quickly."

Minute one: do not look at the clock

This is the hardest one, and the one with the clearest evidence.

In a 2007 study published in the Journal of Behavior Therapy and Experimental Psychiatry, researchers asked people to either watch a clock or not watch one while trying to fall asleep. The clock watchers worried more and took longer to fall asleep. That held for good sleepers as well as poor ones. In a second experiment with people who had long-running sleep trouble, the clock watchers also overestimated how long they had been lying awake.

The number starts the arithmetic, and the arithmetic starts the worry. On a phone, it is also one tap from your inbox.

What to do instead:

• Turn the clock to face the wall before bed. If you need the alarm, it will still go off.
• Leave the phone across the room, or at least face down and out of arm's reach.
• If you already looked, let it go. The number is not information you can use at 3 a.m.

Minutes one to three: fix the heat before you fix your thoughts

If you run warm, there is a decent chance heat is part of why you woke up, and it will keep you up if you ignore it. Do the physical fixes first, quickly, and with as little light and movement as possible.

• Shed a layer, not the whole duvet. If you have two light layers instead of one heavy one, kick off the top one. Throwing everything off means you will be cold and pulling it back in twenty minutes.
• Put one foot out. Your hands and feet are where your body lets heat go. It is the oldest trick in the book because it works with how you are built.
• Flip the pillow. The underside has been sitting in cooler air.
• Drink some cold water, if it is within reach. Mostly so you do not have to get up for it.
• If you are damp, change your top. Damp fabric against your skin will make you cold a few minutes from now, and that cycle of too hot, then too cold, will keep you up on its own. A dry top folded on the nightstand turns this into a thirty-second job instead of a trip down the hall with the lights on. We go into what to keep there in night sweats sleepwear: what to wear to bed if you wake up damp.

Keep the lights off for all of this. If you need to see, use the dimmest light you have, low and pointed away from your face.

Minutes three to ten: give your brain something boring

Once you are physically comfortable, the enemy is your own thinking. At 3 a.m. the mind goes straight to whatever is unresolved: money, a parent, the thing you said in the meeting. Trying to stop thinking does not work. Giving the brain something dull and harmless to do instead often does.

A few options:

The cognitive shuffle. Developed by Luc Beaudoin, a cognitive scientist at Simon Fraser University, who calls it serial diverse imagining. Pick a random, neutral word, say "garden." Take the first letter, G, and picture as many unrelated things starting with G as you can, a few seconds each: a goat, a glove, a guitar, a grapefruit. When you run out, move to A. The point is that the images are random and carry no emotion, which is close to how your mind drifts on its own as you fall asleep. Beaudoin presented his research on it at a joint meeting of the American Academy of Sleep Medicine and the Sleep Research Society.

Slow breathing. Breathe in through your nose, and let the out-breath be longer than the in-breath. Count if counting helps. Do not grade yourself on it.

Name the worry and park it. If one thought keeps coming back, tell yourself plainly that it is a daytime problem and you will deal with it at 10 a.m. Some people keep a notepad by the bed and write one line in the dark. It does not need to be legible.

If it has been about twenty minutes, get up

This is the counterintuitive one, and it comes from stimulus control, a technique developed by Richard Bootzin. It is part of the approach that sleep medicine guidelines recommend first for long-running sleep trouble.

The rule: if you cannot get back to sleep within roughly 15 to 20 minutes, get out of bed. Go to another room. Do something quiet and dull in dim light until you feel sleepy again, then go back to bed. If it does not happen, repeat.

Two important details:

• Estimate the twenty minutes. Do not time them. The guidance is to judge it by feel, not to check the clock. See minute one.
• Make the "something" genuinely boring. A paper book you have read before. Folding laundry. Sitting in a chair with a cup of water. Not your phone, not email, not the news, and not a brightly lit kitchen.

The reasoning is that your brain learns associations. If the bed becomes the place where you lie awake and fret, the bed itself starts to cue fretting. Getting up keeps the bed linked to sleep.

For hot sleepers there is a bonus. Getting up for ten minutes in a cooler room gives your body a chance to shed the heat that built up under the covers. Many people find they go back to bed cooler and settle faster.

Rest is not a reward

Today, October 10, is World Mental Health Day, and this seems like the right day to say one thing plainly: rest is not something you earn by getting enough done. It is not a prize for a productive day.

A lot of 3 a.m. wakefulness is made worse by a voice that counts every lost hour as a personal failing. You lie there grading yourself. You are not sleeping properly. You are going to be useless tomorrow. You should be able to do this.

Lying quietly in the dark, comfortable and not fighting it, is still rest. Your body is still lying down and your muscles are still unclenched. It is not the same as sleep, but it is not nothing, and writing it off as nothing is part of what keeps you awake.

So when it happens, go easier on yourself. You woke up. It is normal. Do not check email, do not plan tomorrow, and do not decide the day is ruined. You will either drift off again or you will not, and either way the day will happen.

Set up tonight so 3 a.m. is shorter

Most of the work happens before you go to bed. Five minutes tonight makes the middle of the night simpler:

1. Turn the clock around. Phone across the room.
2. Set the bedroom between 65 and 68°F. That is the range the Sleep Foundation suggests for most people, and it matters more now that the furnace is back on. For more free ways to get there, see nine ways to make your bedroom colder tonight.
3. Make the bed in two light layers, so you can shed one at 3 a.m. without waking up fully.
4. Fold a dry top on the nightstand, with a glass of cold water next to it.
5. Pick your "get up" spot. A chair in another room, a dim lamp, a boring book already on the seat. Deciding at 3 a.m. is harder than deciding now.

None of it costs anything. Try it for a week before you judge it, because one night tells you very little either way.

The last layer

Once the room is cool and the clock is turned away, what you sleep in is the layer that decides whether the heat you shed at 3 a.m. can leave, which is why we make Still Cool sleepwear from viscose made from bamboo, a light jersey that lets air through.
