Vaping and Sleep: How Nicotine Affects Your Nights and What Helps
Share
Vaping and sleep don't mix as well as many people think. A puff before bed can feel relaxing, but most vapes contain nicotine, and nicotine is a stimulant that can make it harder to fall asleep and stay asleep. This guide covers how nicotine affects sleep, what the research on vaping shows so far, why quitting can disturb sleep for a while, practical steps to protect your nights, and when to see your GP.
The short answer: if your vape contains nicotine, it is likely working against your sleep. Nicotine promotes alertness, breaks up sleep and can cause small withdrawal dips overnight that wake you. Studies of young people link vaping with more insufficient sleep, though most can't prove cause and effect. Quitting may disturb sleep for a few weeks, then usually helps. Quitline (13 7848) and your GP can support you through it.
This guide is general information, not medical advice.
How nicotine affects sleep
The Sleep Health Foundation describes nicotine as a stimulant used to promote alertness, and says it can make it harder to fall asleep and to stay asleep. It also changes sleep architecture, which means the normal pattern of light, deep and dream sleep through the night. The result is sleep that feels disturbed or unrefreshing, with more night-time awakenings. The Foundation notes that many vape fluids contain nicotine, so vaping has similar effects on sleep to cigarettes (source).
Three things are going on at once:
- Stimulation. Nicotine triggers the release of brain chemicals that promote wakefulness, so a late vape works a bit like a late coffee. Our guide to caffeine and sleep explains the same timing problem.
- Overnight withdrawal. Nicotine wears off while you sleep. For regular users, the drop in nicotine can lead to restless, lighter sleep in the second half of the night.
- Habit. If you vape when you wake at 2am, you get another hit of stimulant at exactly the wrong time, and your brain starts to expect it.
What the research says about vaping
Research on vaping and sleep is still young, and much of it focuses on teenagers and young adults.
A 2026 narrative review pulled together the available studies on e-cigarette use and sleep duration in adolescents and young adults. It found that people who only vaped had roughly 30 to 80 per cent higher odds of insufficient sleep. People who both vaped and smoked showed the strongest links, and were up to three times more likely to report inadequate sleep. The authors also suggest the relationship may run both ways: poor sleep may make people more likely to start vaping, and vaping then makes sleep worse. Most of the studies were cross-sectional, so they can't establish cause (source).
That fits what the Sleep Health Foundation reports: a 2023 study found adolescents who vaped were more likely to report having insufficient sleep than those who didn't. Teenagers already need more sleep than adults, so see how much sleep teenagers need if this is a family concern.
Vaping and your health more broadly
Healthdirect describes nicotine as a highly addictive, toxic drug, and lists known risks of vaping including mouth and airway irritation, persistent coughing, nausea, chest pain and palpitations (source). Some of those, such as a cough or a racing heart, are exactly the kind of thing that keeps you awake.
The Sleep Health Foundation also notes that smoking may worsen snoring and sleep apnoea. If you snore loudly or wake gasping, read signs of sleep apnoea and talk to your GP.
In Australia, adults can buy vapes from certain pharmacies without a prescription, subject to conditions, and people under 18 need a prescription, according to healthdirect.
Quitting and sleep: what to expect
Here's the part that catches people out. Sleep often gets worse before it gets better.
The Sleep Health Foundation says about half of former smokers have trouble sleeping while they're trying to quit. Nicotine withdrawal brings irritability, poor concentration and poorer sleep. The same is likely for people quitting nicotine vapes. It is temporary, and it is not a sign that quitting isn't working.
| Stage | What you might notice | What helps |
|---|---|---|
| First few days | Cravings, restlessness, waking more | Keep the vape out of the bedroom |
| First few weeks | Irritability, lighter or broken sleep | Regular wake-up time, daylight in the morning |
| After that | Sleep usually settles | Keep the routine that got you here |
| Any time | Strong cravings or low mood | Call Quitline on 13 7848 or see your GP |
Practical steps to protect your sleep
If you're cutting down or quitting, these help:
- Set a nicotine cut-off. Stop vaping well before bed, the same way you'd stop coffee in the afternoon.
- Keep the vape out of the bedroom. If it isn't on the bedside table, a 3am waking is less likely to turn into a vape. See why you wake up at 3am.
- Don't swap one stimulant for another. Quitting nicotine and doubling your coffee will still hurt sleep. Alcohol isn't a fix either; see does alcohol help you sleep.
- Keep a fixed wake-up time. Even after a broken night, getting up at the same time helps your body clock reset.
- Have a plan for night wakings. Slow breathing, a dull book in dim light, or getting up briefly if you can't settle. Our guide to insomnia and what helps goes further.
- Get support. Quitline or Aboriginal Quitline on 13 7848 (13 QUIT) can help you plan a quit, and your GP can talk about options.
When to see your GP
See your GP if poor sleep lasts more than a few weeks after quitting, if you snore heavily or stop breathing in your sleep, if you have chest pain, palpitations or a cough that won't go away, or if low mood or anxiety is getting in the way of daily life. They can also help with a plan to quit nicotine.
Where the Sovune Nudge fits
We make the Sovune Nudge, a vibrating alarm wristband, so we're not neutral. It won't help you quit, but a calm, consistent wake-up is part of rebuilding a regular sleep routine, and it keeps the phone (and the temptations next to it) away from the bed.
- Set on the band itself. No app, no phone, no Bluetooth, so your phone can live outside the bedroom.
- Wakes you with vibration on your wrist, starting as a gentle tap and building through three intensity levels.
- Each alarm runs for a full minute, stepping up through the levels, and you can switch it off sooner.
- Silent. No speaker and no sound, so it won't wake anyone else.

Quick answers
Does vaping keep you awake? It can. Most vapes contain nicotine, a stimulant that makes it harder to fall asleep and stay asleep.
Do nicotine-free vapes affect sleep? There's much less research on these. Without nicotine the stimulant effect isn't there, but any late-night habit near bedtime can still keep you up.
Why is my sleep worse since I quit vaping? Nicotine withdrawal commonly disturbs sleep for a while. It usually settles within a few weeks.
Is vaping before bed relaxing? It can feel that way because it eases cravings, but nicotine itself is a stimulant, and withdrawal later in the night can wake you.
