Although it is becoming well accepted that there are neurobiological links between sleep dysfunction and substance abuse behavior that result in comorbidity, research is still in its infancy. Earlier, we discussed a simplified anatomical framework that identifies some of the relevant links for this comorbidity, but there are likely other pathways and substrates, some of which still need to be discovered. The precise functional interactions between these different regions and their involvement in the trajectory of drug use has not been explored in any depth. Likewise, how the interaction between sleep and substance use is shaped by genetics, life events, sex, and circadian rhythms remains unknown. Further research to fill the knowledge gaps at the intersection of sleep, drug reward, and addiction will help identify treatment targets that improve the quality of life of individuals suffering from sleep and substance use disorders. The rest of the animal literature is consistent with the human studies, showing continued circadian disturbance during acute discontinuation of chronic alcohol use, with improvements in circadian functioning as abstinence continues.
1 Acute effects of alcohol on sleep: repeated administration
This would be consistent with a state of heightened arousal that accompanies craving. These findings provide a rationale for the evaluation of orexin antagonists, such as suvorexant, a drug currently approved for use for insomnia, as therapy for substance use disorders and for the development of new ones. These agents may provide a two-fold benefit by preventing two distinct but interrelated effects of orexin, potentiation of reward and arousal effects, which could help attenuate drug reward and improve sleep disturbances.
Alcohol and sleep I: effects on normal sleep
Medicine can also have more severe side effects, like heart palpitations or shortness of breath. Anytime you experience side effects, you should consult your health provider to see if they advise continuing the medication. Since alcohol affects everyone differently, it’s important to understand where your limit lies and how much alcohol you can drink before it starts to affect your sleep. If you’re looking for ways to improve your sleep, an easy place to start is by adopting healthy sleep hygiene habits such as keeping a consistent sleep schedule and creating a calming bedroom environment. For most people, alcohol induces a deeper-than-usual sleep in the first half of the night, followed by disrupted sleep in the second half of the night.
Sleep and circadian risk factors for alcohol problems: A brief overview and proposed mechanisms
- Each sleep stage plays an essential function, but deep sleep and REM sleep are considered the most important stages for physical and mental restoration.
- Although we believe the existing evidence makes a compelling case for the value of understanding the role of sleep and circadian characteristics in risk for later alcohol involvement and alcohol use disorder, a number of important questions remain.

- This observation is significant, because many hypnotic drugs (i.e., barbiturates, benzodiazepines, and the newer non-benzodiazepine GABA agonists5) also act by facilitating GABA function.
- In addition, bursts of activity occur during the phasic periods in body functions that are controlled by the autonomic nervous system1; these bursts of activity are reflected by irregularities in cardiopulmonary function (e.g., heart rate and breathing rate).
- In summary, this emerging literature linking the circadian system to appetitive motivation, as well as behavioral indicators and the neural circuitry of reward, offers the potential for specific mechanistic hypotheses about how drug abuse and circadian misalignment might fall into a vicious cycle.
- Studies of the effects of repeated alcohol administration over multiple nightsare rare and suffer from small sample sizes.
This molecule is not a neurotransmitter itself but modulates signal transmission by other neurotransmitters, including GABA and glutamate. In general, adenosine inhibits the function of glutamate in the CNS (Dunwiddie 1996). Adenosine has been hypothesized to function as the sleep homeostat—the system that monitors the accumulated amount of wakefulness and sleep and signals the need for sleep (Bennington and Heller 1995).
Poor sleep negatively impacts your health
Caffeine affects the central nervous system and can cause shortened or poor-quality sleep and daytime sleepiness. Sleep apnea, a disorder characterized by halted breathing for short periods while you sleep, may lead to high blood pressure, stroke, or memory loss. Other common sleep disorders involve involuntary body movements, including restless leg syndrome, periodic limb movement disorder, and rapid eye movement (REM) sleep behavior disorder. The right mattress can often help with some of these conditions, like sleeping on an adjustable bed can reduce heartburn and even some sleep apnea symptoms, or finding the best mattress for back pain can help alleviate disruptive aches and pains.
How Does Alcohol Withdrawal Affect Sleep?
Only one daytime study using a modified MSLT assessed alcohol’s sleep effects during both the ascending and descending phase of the does alcohol help you sleep BrACs. That study found increased sleep latencies at peak BrACs relative to placebo, consistent with alcohol’s stimulatory effects under these conditions (Papineau et al. 1988). During the subsequent descending phase of the BrACs, however, sleep latencies were reduced relative to placebo, confirming alcohol’s biphasic effects. In addition to GABA and the glutamate-NMDA system, another agent that only recently has been considered a candidate for mediating alcohol’s sleep effects is adenosine.
Then, talk to your doctor about the changes you can make on a daily basis to improve your sleep quality. While there’s no one-size-fits-all solution to achieving optimal sleep, an individualized approach may include adjustments to medication, supplements, daily routines, and sleep hygiene. By following this approach, you may be able to help improve your sleep quality and overall well-being. Additionally, the body changes as we age, and we may absorb medications less quickly and effectively.
- Consequently, as previously noted, alcohol’s effects on measures of sleep induction and maintenance in healthy people are minimal and inconsistent.
- The circadian rhythm is responsible for keeping the body anchored to a 24-hour cycle.
- This can be even harder if you’ve been addicted to drugs or alcohol and you’re trying to stop.
- This video for middle school students explains how synthetic cathinones, commonly known as bath salts, affect the brain…
- It may also take the body longer to eliminate medication, prolonging its intended effects.
- A newer study found that one dose of alcohol had no effect on the circadian rhythm in rodents.
Alcohol’s Effects on Sleep Physiology
It is well recognized that sleep problems have a significant impact on quality of life with increased morbidity and mortality seen in population studies3. Identifying people at risk of sleep disturbances as a result of their drinking may have important public health benefits. Taking a developmental perspective, this model may have particular relevance during adolescence, a qualitatively distinct period with regard to substance use and other risk-taking behavior, reward processing, and emotion regulation (99). Notably, this period is also marked by changes in sleep and circadian timing, in which sleep times and circadian phase are trending later while school start times are moving earlier (100). The resulting misalignment and instability may impair reward processing and emotion regulation, perhaps in part due to effects on executive control, increasing the risk for early onset of substance use, and eventual abuse and/or dependence. The onset of substance use during adolescence may in turn exacerbate these changes in sleep, circadian, reward, and emotion regulation.
