How to Stay Awake in a Meeting
There is a kind of tired that only exists in meetings. You were fine at your desk ten minutes ago, and you will be fine again ten minutes after this ends. But right now, on slide nine of a roadmap review, your head has started making small decisions without consulting you.
This is not a character flaw. A typical meeting stacks up nearly everything that makes a person drowsy: sitting still, a warm room, dimmed lights, one voice at a steady pitch, and often an early-afternoon slot. Researchers generally define a microsleep as an episode of sleep lasting 15 seconds or less, and people often don't realize they've had one. The Sleep Foundation notes that even fully rested people can have them while doing something repetitive or tedious, which is a polite description of a status update.
So the useful question is not how to be more disciplined. It is which of those ingredients you can remove, and how visibly. The list below runs from cheap and invisible to effective and noticeable.
In the moment: when it's already happening
Make yourself less comfortable. Comfort is the enemy here. Sit forward with both feet flat on the floor and your back off the chair. If you are leaning back with your arms folded, you have built a bed and are lying in it. None of this is magic, but a body holding itself up notices sooner when it starts to stop.
Give your hands a job. Take notes, by hand if you can, and make them notes that require thought: the decisions made, who owns what, the question you'd ask if called on. Transcribing every word is nearly as hypnotic as listening. Summarizing is not, because you have to keep deciding what matters.
Drink water, then go and get more. The case for water as an alertness aid is real but modest. A review of the research found little evidence that everyday mild dehydration impairs thinking in young adults, but people who went without fluids for long stretches rated themselves more tired and less alert, and alertness ratings rose after a drink. The bigger benefit is the refill: a socially unimpeachable reason to stand up and walk across the room.
Stand up. In a room, stand at the back or by the wall; "my back's stiff" is a sentence nobody has ever questioned. Movement helps, and more movement helps more. In one small study, ten minutes of walking up and down stairs at an easy pace left sleep-short college women feeling more energetic than a dose of caffeine about the size of a can of soda, though the lift was brief and didn't sharpen attention or memory. A later study of a four-minute version found no significant change. The honest summary: a short walk gives you a lift, the lift fades, so spend it close to the part of the meeting that needs you.
Ask a question. Nothing wakes you up like hearing your own voice in a quiet room. Decide on a question early, while you're still sharp, and keep it for the moment you feel yourself fading. The guide to getting out of a meeting covers which questions are safe when you haven't been following closely.
Find the light. If you can choose your seat, face the window. If the room has been dimmed for slides, that is working against you, and asking to bring the lights up is a reasonable request in any meeting that isn't a film screening. In a small 2021 study, students kept from their usual afternoon nap felt less sleepy under bright, bluish-white light than under ordinary indoor lighting, and by the end of the session the difference from actually napping was no longer significant. The Sleep Foundation suggests outdoor light for the afternoon slump for much the same reason.
Cool down. Take off the jacket, sit near the door, ask for the window. In a controlled study of 36 people working at 24°C, 26°C and 28°C (about 75°F, 79°F and 82°F), 12 of 14 measures of mental performance fell at the warmer temperatures, even though clothing and airflow were adjusted so that everyone felt comfortable, and participants didn't rate their own performance any differently. That study measured performance rather than drowsiness, but the lesson carries: a comfortably cool room beats a cozy one, and you won't necessarily feel the difference.
Leave for two minutes. If none of that works, step out. A two-minute absence is unremarkable; a ten-second nod in a meeting of six is what people remember. Walk the long way back and return before your agenda item.
One thing that doesn't help much in the moment: the coffee you fetch mid-meeting. Caffeine takes about 30 minutes to take effect, so the cup you grab when you're already nodding is working on the next meeting, not this one.
Over the day: setting yourself up
Most meeting sleepiness is decided before the meeting starts. Four things do most of the work.
Know about the dip. The signals from your body clock that keep you awake tend to weaken in the early afternoon, which is why the 2pm slot feels the way it does. The Sleep Foundation notes that this post-lunch dip happens even if you skip lunch, and that the old explanation, blood rushing from your brain to your stomach, has been debunked. If you control the calendar, don't put your most demanding meeting there.
Eat a lighter lunch before an afternoon meeting. Skipping lunch doesn't remove the dip, but what you eat can deepen it. According to the Sleep Foundation, a lighter, lower-calorie meal is likely to cause less sleepiness than a heavy one, and a high-carbohydrate meal is more likely to make you sleepy than a low-carbohydrate one. A large bowl of pasta at 1:00 followed by a budget review at 1:30 is a plan with a predictable ending. A brisk walk after lunch, outside if possible, gets you movement and daylight in one go.
Time the caffeine, and stop it early. Because caffeine takes about half an hour to kick in, the coffee at 1:30 is the one for the 2pm meeting. The harder part is the cutoff. In a study in the Journal of Clinical Sleep Medicine, a large dose (400 mg) taken six hours before bed still cut measured sleep by more than an hour, and participants largely didn't notice. The authors advised avoiding substantial caffeine for at least six hours before bedtime; the Sleep Foundation suggests eight, which for an 11pm bedtime means the last coffee around 3pm. This matters because a late coffee sets up a loop: worse sleep tonight, a deeper dip tomorrow, a bigger coffee to fight it. For scale, the FDA cites 400 mg a day (two to three 12-ounce cups of coffee) as an amount not generally associated with negative effects for most adults, while noting that people vary widely in how sensitive they are and how fast they clear it.
Sleep, which is the actual answer. Everything above is a patch. The CDC recommends at least seven hours a day for adults. Tiredness feels more intense when you're short on sleep, so the same 2pm meeting that is a mild dip after a full night can be a cliff after a short one. If you are fighting to stay awake in most meetings, the meetings are probably not the problem.
Remote meetings
Working from home removes some of the problems and adds new ones. The thermostat and the light switch are yours, which is a real advantage. So are the couch and the bed, which is not.
Don't take the call somewhere you sleep. A call taken lying down, or from the sofa under a blanket, is a nap with a microphone. Sit at a table, or stand with the laptop on a counter.
Use the camera deliberately. In a four-week field experiment with 103 employees, days with cameras on were linked to more fatigue, and that fatigue went with speaking up less and engaging less in meetings, with the effect strongest for women and newer employees. Where your team's norms allow it, camera off is reasonable for large listen-only calls. The catch is that camera off also removes the social pressure that keeps you upright, so pair it with standing or moving.
Hide your own video. Stanford researcher Jeremy Bailenson has argued that watching your own face for hours, and being pinned inside the camera's frame, are two likely reasons video calls feel so draining. His paper is explicit that these are arguments not yet tested, but the fixes cost nothing: turn on "hide self view," push the laptop further back, use an external keyboard so you can sit back or stand, and make some calls audio-only. A listen-only call taken on headphones during a walk gets you movement and daylight at once, and it is remarkably hard to doze off mid-stride.
Use the nap you can actually take. At home, a short afternoon nap is an option the office doesn't offer. The Sleep Foundation recommends about 20 minutes and no more than 30, since longer naps can leave you groggier, and taking it before about 3pm so it doesn't disturb the night. It also notes that caffeine just before a short nap may increase alertness afterward, because it starts working around the time you wake up. Take the nap before the meeting you need to be sharp for, not during the one you don't.
When it's more than a dull meeting
Most meeting sleepiness is exactly what it looks like: a still, warm room in the early afternoon. But if you regularly struggle to stay awake even after a full night's sleep, or find yourself nodding off in situations that aren't boring at all, that is worth mentioning to a doctor, in the same unhurried way you'd mention a knee that keeps aching. Daytime sleepiness is a listed symptom of sleep apnea, which the NHLBI notes people often don't know they have until someone else tells them, and the Sleep Foundation lists other conditions that can show up as unusual sleepiness after meals, including an underactive thyroid, anemia and diabetes. Finding out usually starts with an ordinary appointment and sometimes a sleep study. If it ever happens while you're driving, make that appointment sooner rather than later.
The honest version
If one particular meeting reliably puts you to sleep, it may be telling you something. A recurring hour that nobody needs to be awake for is a good candidate for the could-it-have-been-an-email test, and that conversation will do more for your afternoons than any amount of cold water. For the meetings you genuinely can't change, the list of things to do when you're bored in a meeting has fifty more ways to keep part of your brain switched on.
Until then: sit forward, keep the notes, face the window, and save your question for the moment your eyelids start losing the argument.
