You might think a drink or two helps you sleep better, but what if it does the opposite? For people with sleep apnea, that nightly glass of wine could be turning restful sleep into a silent struggle for air. Sleep apnea is a serious sleep disorder characterized by repeated interruptions in breathing during sleep. However, it significantly contributes to an increase in the risk of sleep apnea by 25%. While various factors contribute to its development, recent studies have highlighted a significant link between alcohol and sleep apnea symptoms.What Is Sleep Apnea?
Sleep apnea is a disorder in which breathing repeatedly stops and starts during sleep. However, the most common type is Obstructive Sleep Apnea (OSA), which occurs when the throat muscles relax excessively during sleep, blocking the airway. Another type is central sleep apnea, in which the brain fails to send appropriate signals to the muscles that control breathing. Moreover, the combined effect of alcohol and sleep apnea disruptions can include loud snoring, gasping during sleep, and extreme fatigue during the day.The Relationship Between Alcohol and Sleep Apnea
Researchers have established a strong relationship between alcohol and sleep apnea, particularly in how alcohol acts as a central nervous system depressant. It relaxes the muscles of the throat; this relaxation can lead to increased airway obstruction, making breathing difficult during sleep. Therefore, studies have shown that alcohol consumption can exacerbate sleep apnea symptoms, leading to more frequent and severe episodes.How Does Alcohol Cause Sleep Apnea?
Here are a few key takeaways alcohol and sleep apnea interact negatively:- Muscle Relaxation: Alcohol causes throat muscles to loosen, increasing airway obstruction.
- Impaired Arousal Response: Alcohol dulls the brain’s response to breathing interruptions.
- Sleep Stage Disruption: Alcohol interferes with deep sleep, increasing lighter sleep stages and contributing to more frequent apneas.
How Does Alcohol Affect Sleep?
While alcohol may initially make you feel drowsy, it disrupts the sleep cycle. However, the link between alcohol and sleep apnea reduces the proportion of REM sleep, essential for cognitive function and memory consolidation, and increases the proportion of lighter sleep stages. Furthermore, this disruption can lead to frequent awakenings and less restful sleep.Does Alcohol Affect a Sleep Apnea Test?
Yes, alcohol can significantly affect the results of a sleep apnea test and not in a good way. However, if you’re preparing for a sleep study, whether at a lab or home, consuming alcohol beforehand can distort the findings and lead to an inaccurate diagnosis or an overestimation of severity.Here’s how alcohol interferes with a sleep apnea test:1. Exaggerated Apnea Events
Alcohol relaxes the muscles of the upper airway, which increases the likelihood of airway obstruction. As a result, you may have more frequent or longer apneic episodes than you would on a normal night. While this might help reveal a problem that only occurs when drinking, it doesn’t give an accurate picture of your day-to-day sleep apnea severity.2. Suppressed Arousal Response
When your body stops breathing, it wakes you up slightly to restart airflow. Moreover, alcohol dampens this natural reflex, allowing apneas to last longer and causing deeper oxygen desaturations, which can make the condition appear more dangerous than it is during testing.3. Disrupted Sleep Architecture
Alcohol affects your sleep stages, particularly by reducing REM sleep and increasing lighter stages. Since apneas often worsen during REM, this can skew test sleep test results, either underrepresenting or overrepresenting your typical sleep apnea pattern.Struggling with Sleep Apnea?

Risk Factors of Sleep Apnea
The combined effect of alcohol and sleep apnea is intensified by other risk factors such as:
- Obesity
- Age (40+)
- Male gender
- Smoking
- Family history of OSA
Among these, alcohol use is one of the most common and modifiable risk factors for worsening sleep apnea symptoms.
Should You Avoid Alcohol Before Sleep Study?
Absolutely. Most sleep specialists recommend avoiding alcohol for at least 24 hours before your sleep apnea test. However, this ensures the results reflect your regular breathing patterns and sleep quality rather than a one-off alcohol-influenced night.
What If You Suspect Alcohol Triggers Your Symptoms?
In some cases, alcohol may be the main trigger for sleep apnea symptoms, especially if you only notice snoring, gasping, or fatigue after drinking. In such scenarios, scheduling a follow-up test under controlled conditions might be appropriate. Be sure to discuss this with your sleep specialist.
Can Drinking Alcohol Worsen Obstructive Sleep Apnea?
Absolutely. Drinking even moderate amounts of alcohol can lead to longer, more severe apneic episodes. Moreover, the interaction between alcohol and sleep apnea makes the condition harder to manage, especially for those using therapies like CPAP.
How Alcohol Impacts Other Sleep Problems?
The negative influence of alcohol and sleep apnea is not limited to breathing disorders. Alcohol can also worsen:
- Insomnia
- Restless leg syndrome
- Circadian rhythm disruptions
- These overlapping issues further reduce overall sleep quality.
How to Stop Snoring After Drinking Alcohol
To reduce snoring and minimize the impact of alcohol and sleep apnea, follow these tips:
- Avoid alcohol 3–4 hours before sleep
- Sleep on your side
- Stay hydrated
- Use nasal strips to keep airways open
Can I Use CPAP After Drinking Alcohol?
Yes, but it’s not ideal. Alcohol may reduce your responsiveness and compromise the effectiveness of CPAP. In addition, if you’re managing alcohol and sleep apnea, it’s best to avoid alcohol altogether before bed.
What are the Triggers of Alcohol, Snoring, and Sleep Apnea?
Snoring is a common symptom of sleep apnea. However, alcohol can increase the frequency and loudness of snoring by relaxing the throat muscles. Moreover, Persistent snoring, especially after drinking alcohol, can be a sign of sleep apnea and should be evaluated by a healthcare provider.
Tips for People Living with Sleep Apnea
To better manage alcohol and sleep apnea, try these:
- Avoid alcohol, especially at night
- Use CPAP consistently
- Lose weight if needed
- Sleep on your side
- Attend regular sleep checkups
When to See a Doctor
Consult a healthcare provider if you experience:
- Loud snoring
- Choking during sleep
- Excessive daytime fatigue
- Difficulty concentrating
If you’re experiencing symptoms that worsen after drinking, your case of alcohol and sleep apnea may require medical attention. However, don’t delay getting a sleep study or speaking with a specialist.
