Vaping And Sleep: Does Nicotine From Vaping Steal Your Sleep?

Quick Summary

• A major scientific review found that people who use e-cigarettes have a 38% higher risk of getting insufficient sleep compared to non-users.

• Vaping is linked to a range of sleep problems beyond just short duration, including trouble falling asleep, poor sleep quality, and a greater need for sleep medication.

• The nicotine in e-cigarettes is a stimulant that directly interferes with the parts of the brain that control sleep, leading to more wakefulness and disrupted sleep.

• Adolescents and young adults who vape seem to be especially affected, with studies showing they have a much higher risk of not getting enough sleep.

Vaping And Sleep: The Science

Electronic cigarettes, often called e-cigarettes or vapes, are devices that heat a liquid to produce an aerosol that users inhale.

While often marketed as a less harmful alternative to traditional cigarettes, a growing number of studies are uncovering their potential health risks, particularly when it comes to sleep (Sulthana et al., 2025).

Many people understand that the quality of their sleep directly impacts their physical and mental health, affecting everything from immune function to daily productivity (Hillman et al., 2018). But the connection between vaping and sleep has been less clear.

To get the most reliable answer on this topic, Sulthana and colleagues recently performed a meta-analysis, a powerful type of review where researchers gather all the existing studies on a topic and combine their data. By analyzing the results of 14 different studies together, they were able to draw a much clearer and more confident conclusion about the link between vaping and sleep.

So, what does the science actually say about the impact of e-cigarette use on our nightly sleep?

Does Vaping Negatively Affect Sleep?

Yes, a comprehensive scientific review confirms a strong link between e-cigarette use and an increased risk of multiple sleep problems. The analysis, which combined the results of 14 different studies, found consistent evidence that vaping is associated with:
- shorter sleep duration,
- poorer sleep quality, and
- more frequent sleep disturbances (Sulthana et al., 2025).

This connection appears to be widespread, affecting various age groups, from adolescents to adults.

The findings suggest that the stimulating effects of nicotine, the main chemical in most e-liquids, are a likely cause of this disruption.

This raises an important question: what is the biological reason for nicotine disrupting sleep?

How Exactly Does Nicotine From Vaping Disrupt Sleep?

The nicotine in e-cigarette vapor disrupts sleep primarily because it is a powerful stimulant. When inhaled, nicotine activates specific pathways in the brain that promote wakefulness and suppress sleep, interfering with your body's natural sleep-wake cycle (Sulthana et al., 2025).

Nicotine works by binding to a set of receptors in the brain known as nicotinic acetylcholine receptors (nAChRs). Certain types of these receptors are crucial for regulating sleep stages and brief awakenings, known as micro-arousals ( Léna et al., 2004).

By activating these receptors, nicotine can break up your sleep into smaller, less effective pieces, making it lighter and less refreshing.

Furthermore, some research suggests that nicotine can weaken the body's natural alarm system that is supposed to wake you up if there's a problem, like a drop in oxygen. This can worsen conditions like sleep-disordered breathing and may also reduce the amount of oxygen in your blood at night, similar to the effects seen in traditional smokers (Cohen et al., 2002; Sulthana et al., 2025).

The more intense the nicotine use, the greater the sleep disturbance tends to be.

To understand the full picture, it's helpful to look at the specific ways vaping can interfere with sleep.

How Much Shorter Is Sleep for People Who Vape?

People who use e-cigarettes are 38% more likely to experience short or insufficient sleep than those who do not vape (Sulthana et al., 2025).

The consistency of this finding across different studies is notable. For example, one study focusing on adults found that current e-cigarette users were 1.82 times more likely to report shorter sleep durations compared to non-users (Wiener et al., 2020).

Another large-scale study of over 179,000 adults in Korea found that vapers were significantly more likely to sleep less than the recommended seven hours per day (You et al., 2023).

This evidence suggests that the link between vaping and getting less sleep is not a coincidence. But does this risk apply to everyone equally?

Are Teenagers and Young Adults More Affected?

The research indicates that adolescents and young adults who use e-cigarettes are particularly at risk for sleep problems. Several large studies focusing on these age groups have found a clear and significant association between vaping and inadequate sleep.

One study of U.S. high school students found that those who used e-cigarettes had a 61% higher chance of getting insufficient sleep (Merianos et al., 2021).

Another large survey of adolescents found that using electronic vapor products was linked to a 33% increased risk of not getting enough sleep, even when researchers took other factors into account, like the participants' age and background.

The pattern continues among college students, where research has shown that e-cigarette users report poorer overall sleep quality and a greater number of sleep disturbances (Brett et al., 2020).

Given how important sleep is for brain development, learning, and managing emotions during the teen years, these findings are especially concerning.

While getting enough hours of sleep is important, the quality of that sleep matters just as much. So, what other sleep problems are linked to vaping?

What Other Sleep Issues Are Associated With Vaping?

Beyond simply reducing the amount of sleep, e-cigarette use is also linked to a lower quality of sleep and specific sleep disorders. Studies show that people who vape are more likely to have trouble falling asleep, experience restless nights, and even rely on medication to get to sleep (Sulthana et al., 2025).

This broader impact on sleep health suggests that the effects of vaping go beyond a simple delay in bedtime. The chemicals involved, particularly nicotine, appear to disrupt the very architecture of sleep itself.

Let's look closer at how this affects the experience of falling and staying asleep.

Can Vaping Make It Harder To Fall And Stay Asleep?

Yes, research shows that e-cigarette users report more difficulties falling asleep and staying asleep than non-users. A study involving college students found that sleep disturbances were significantly more common among vapers, who were also more likely to use sleep medications compared to their non-vaping peers (Brett et al., 2019).

Another study found that adults who used e-cigarettes had more than double the odds of reporting "trouble sleeping" (Wang et al., 2024).

This difficulty falling asleep is often referred to by researchers as increased sleep latency. For individuals who use both e-cigarettes and traditional tobacco, this problem can be even more pronounced, with studies showing they take significantly longer to fall asleep (Advani et al., 2022).

These findings point to a direct interference with the body's ability to initiate and maintain sleep.

So if vaping disrupts sleep at night, what is the effect the next day?

Does Vaping Lead To More Daytime Sleepiness?

The poor sleep associated with e-cigarette use often carries over into the next day, leading to increased daytime sleepiness and dysfunction. When sleep is frequently interrupted or cut short, the body and brain don't have enough time to complete the restorative processes that happen overnight.

One study specifically found that how often someone used e-cigarettes was a key factor linked to problems with daily activities due to sleepiness (So et al., 2021).

Another study of adolescents found that e-cigarette users had more sleep-related complaints overall, including not only restless sleep and bad dreams but also falling asleep during the day (Riehm et al., 2019).

These studies suggest that the consequences of vaping on sleep aren't confined to the night but can impair a person's alertness and functioning throughout their waking hours.

While the disruptive effects of vaping look like insomnia symptoms, it’s important to consider whether vaping is linked to any other major sleep disorders.

Is There a Link Between Vaping and Obstructive Sleep Apnea?

Currently, the scientific evidence for a direct link between e-cigarette use and obstructive sleep apnea (OSA) is inconclusive. Obstructive sleep apnea is a serious sleep disorder where breathing repeatedly stops and starts during sleep.

The 2025 meta-analysis found only one study that specifically investigated this relationship (Sulthana et al., 2025). That study did not find a strong enough link between vaping and OSA to be considered scientifically meaningful (Zhu et al., 2023). While nicotine's known effects on oxygen levels and arousal during sleep suggest a potential connection, more targeted research is needed to determine if vaping is a risk factor for developing or worsening sleep apnea.

To properly interpret these findings, it's also important to understand the nature of the research itself.

What Are the Limitations of This Research?

A key limitation of the current research is that it is based on cross-sectional studies. A cross-sectional study is a type of research that looks at data from a population at one specific point in time. While these studies are excellent for identifying associations, like the link between vaping and poor sleep, they cannot prove that one causes the other.

For example, it's possible that people who already have trouble sleeping are more likely to start vaping, perhaps as a coping mechanism. To establish a clear cause-and-effect relationship, researchers would need to conduct longitudinal studies, which follow participants over a long period.

The review also noted that most of the studies were conducted in the United States, so the findings may not apply universally to all populations (Sulthana et al., 2025).

Despite these limitations, the consistency of the association across 14 different studies provides strong evidence that the relationship between vaping and poor sleep is real and warrants attention.

Where To From Here?

The evidence clearly shows a strong and consistent link between using e-cigarettes and experiencing significant sleep problems. If you vape and have noticed it's become harder to fall asleep, that you're waking up more often, or that you feel tired during the day, know that this is a recognized and well-documented issue. The stimulant effects of nicotine are a likely contributor to these challenges.

Understanding this connection is the first step. The next is recognizing that improving your sleep is possible but it will likely require nicotine cessation if nicotine is the culprit. To quit vaping, the most effective approach is to talk to your primary healthcare provider about nicotine cessation programs. It may also be helpful to talk to them about whether working with a behavioural sleep medicine specialist may be and option, rather than relying on generic sleep tips.

A sleep psychologist can often a structured program tailored to you that targets the specific behaviors and biological factors that could inadvertently worsen sleep during the nicotine cessation program. They can help you create a personalized plan to address the factors affecting your sleep, helping you to reduce your reliance on nicotine and rebuild healthy, natural sleep patterns.

Frequently Asked Questions About Vaping and Sleep

Q1: Does vaping affect your sleep?

A1: Yes, vaping has a negative effect on sleep. A major scientific review of 14 studies confirmed a strong and consistent link between using e-cigarettes and experiencing a range of sleep problems, including getting less sleep, having poorer sleep quality, and more frequent nighttime disturbances (Sulthana et al., 2025).

Q2: Can vaping make you sleep less?

A2:  Yes, vaping is linked to shorter sleep duration. A large-scale analysis found that people who use e-cigarettes are 38% more likely to get an insufficient amount of sleep compared to people who do not vape (Sulthana et al., 2025). One study noted that vapers were 1.82 times more likely to report sleeping for shorter periods (Wiener et al., 2020).

Q3: Why does vaping disrupt sleep?

A3:  Vaping disrupts sleep because most e-liquids contain nicotine, which is a powerful stimulant. When you inhale nicotine, it activates parts of your brain that promote wakefulness, interfering with your body's natural sleep-wake cycle. This can break up your sleep, making it lighter and less refreshing (Sulthana et al., 2025).

Q4: Can vaping cause insomnia or make it harder to fall asleep?

A4: Yes, vaping is associated with difficulty falling asleep, a key symptom of insomnia. Research shows that e-cigarette users are more than twice as likely to report having "trouble sleeping" (Wang et al., 2024). They also report a greater need to use sleep medications compared to non-vapers (Brett et al., 2020).

Q5: Does vaping make you more tired during the day?

A5: Yes, the poor sleep quality caused by vaping can lead to increased daytime sleepiness. When sleep is cut short or disrupted by nicotine, your body doesn't get the full rest it needs. Studies have found a direct link between how often a person vapes and how much they struggle with sleepiness during their daily activities (So et al., 2021).

Q6: Are young people more at risk for sleep problems from vaping?

A6: The evidence suggests that adolescents and young adults are particularly affected. Studies have shown that high school students who vape have a significantly higher risk of getting insufficient sleep (Merianos et al., 2021). This is a major concern because sleep is essential for brain development and learning during these years.

Q7: Is there a link between vaping and sleep apnea?

A7: Currently, there is not enough scientific evidence to confirm a direct link between vaping and obstructive sleep apnea (OSA). A comprehensive review found only one study on the topic, and it did not find a scientifically meaningful connection (Zhu et al., 2023; Sulthana et al., 2025). More research is needed to understand if any relationship exists.
