The Advice You Need to Hear About Alcohol and Sleep Apnea

Curious about how drinking alcohol can impact the symptoms of Obstructive Sleep Apnea and other sleep disorders? Do you struggle with insomnia after drinking? Research has shown that alcohol consumption can worsen the impacts of Sleep Apnea and impair your ability to get a good night’s sleep.

We’ll provide tips on how to get a better night’s sleep if you choose to drink, and answer common questions that you may have about how drinking impacts sleep health.

If you suffer from Obstructive Sleep Apnea, you should know that alcohol and Sleep Apnea do not mix well. Drinking alcohol can actually increase apneic events and their duration, worsening your Sleep Apnea symptoms.

How Does Alcohol Affect Sleep Apnea?

Alcohol makes your muscles relaxed, including the muscle tissue in your airway. You may recall that Sleep Apnea is a disorder caused by the relaxed muscles of the mouth and throat expanding during sleep. This expansion causes a blockage of the airway that prevents air from reaching the lungs.

This causes the symptoms of Sleep Apnea. When you drink alcohol, your muscles are very relaxed; diminishing your arousal response time.

What is “arousal response”? Arousal response is how your body knows to wake up when you can’t breathe because of a blocked airway. Drinking diminishes this arousal response, and it means that you won’t wake up as easily when your breathing stops because of Obstructive Sleep Apnea.

Without that response, your body is less likely to interrupt an apneic event naturally. If you stop breathing, it could take longer to wake up, meaning you’ll be without oxygen for an extended period.

Because less air is getting through to your lungs, it means that when you wake up, you’ll experience more fatigue, tiredness, and daytime drowsiness– in addition to a possible hangover.

Does Alcohol Cause Sleep Apnea?

Alcohol doesn’t cause Sleep Apnea, but research shows that among patients who engaged in habitual alcohol use, regular drinking puts you at higher risk for developing Sleep Apnea, and can make current Sleep Apnea episodes worse. The best recommendation for patients that are at risk of developing Sleep Apnea is to abstain from drinking2 as alcohol and Sleep Apnea don’t work well together.

Can Alcohol Keep You Awake?

Contrary to what you may think, drinking alcohol actually keeps you awake, and makes it harder to fall asleep and stay asleep. It also messes with the body’s melatonin levels and makes sleep less productive overall. According to scientists writing for the National Institute of Alcohol Abuse and Alcoholism:

“Such studies indicate that alcohol interacts with sleep deprivation and sleep restriction to exacerbate daytime sleepiness and alcohol-induced performance impairments.3

This is why, for people that suffer from the effects of Sleep Apnea, it’s best to avoid alcohol if possible to get the best sleep. But if you are in a situation where you know you will be drinking, we’ve compiled some potential tips on how to sleep better after consuming alcohol which we’ll go over in the next section.

How to Sleep Better After Drinking Alcohol

Secret #1: Use an APAP Machine

In most cases, it is best to avoid drinking alcoholic beverages late at night, but sometimes this cannot be avoided. If alcohol is a part of your lifestyle, you should consider using an auto CPAP machine. As your muscle tissue relaxes, an increase in pressure may be needed to keep your airway open.

An auto CPAP machine (APAP machine) can detect and increase air pressure to make sure you get the necessary higher pressure for effective, continuous treatment throughout the night.

Luckily there are a lot of auto CPAP machines available on the market each sporting there own features and options like the DreamStation Auto or the ResMed AirSense 10 AutoSet.

These two options for APAP machines are among the most popular, but there are many other models that can be just as effective as those two machines.

Secret #2: Become a Side Sleeper

Side sleeping is another tactic you can put to use immediately that can help you sleep better– whether you’ve imbibed or not. A recent study found that alcohol and Sleep Apnea are a bad combo, as ingestion increases the Obstructive Sleep Apnea symptoms that the CPAP is fighting against, making it harder for air to reach your lungs4.

Side sleeping allows gravity to open a fully relaxed airway and makes the CPAP machine more effective5. Side sleeping can mean the difference between a poor night of sleep and a great one. If you’ve consumed alcohol at all, it’s going to make your apnea symptoms worse, but sleeping on your side can help your CPAP machine work better and may help you get the therapy you need.

There’s one sleep position you’ll want to avoid if you’ve been drinking. Research has shown sleeping on your back is the worst sleep position for Sleep Apnea5. Drinking compounds the problems that you’ll have in this position. Just as gravity helps keep your airway open when you sleep on your side, gravity also works to close your airway when you sleep on your back.

As if alcohol and Sleep Apnea weren’t enough, sleeping on your back causes you relaxed airway to hang down– naturally blocking the airway. Your CPAP or APAP machine will have to work harder and fight gravity in keeping your airway open.

As a person who also suffers from Sleep Apnea, I naturally prefer to sleep on my back first, even though I know I shouldn’t. It was the most comfortable position for me. I find that during the night while sleeping, I’m more likely to naturally drift towards this position.

I’ve had to learn to force myself to sleep on my side. Sleeping on my side has been a new thing for me, and definitely takes some getting used to, but the benefits I’ve noticed are enormous. My AHI is lower, my breathing is better, and I have increased energy– even when I consume alcohol. Try it yourself tonight, and see if it makes a difference.

Secret #3: Watch How Much Alcohol You Consume

It goes without saying, that if you’re concerned about how you sleep, you’ll want to watch the number and alcohol content of the drinks you consume. However, if you choose to drink, opting for drinks that are lower in alcohol content and limiting yourself to a fixed number will help you as you prepare to sleep.

It’s also recommended that you stop drinking altogether at least two hours before you go to bed. This will give the alcohol time to metabolize through your system and make it easier to fall asleep.

Studies have shown that the more you drink, the worse you make your Sleep Apnea symptoms6. Even one drink per day with dinner can have an impact on how you sleep. The scientific evidence shows that limiting the number of drinks you consume before bedtime can make for a better more restful sleep.

Moderate drinking, as opposed to heavy drinking, can make a big difference in the quality of your sleep. Scholarly reports and research suggest eliminating alcohol consumption entirely as the best way to eliminate the effects of alcohol consumption on Sleep Apnea.

    I have switched to a zero gravity chair that allows me to sleep in a sitting /semi upright position any data on such an arrangement on Apnea, when I was “sleep tested ‘ I did not exhibit apnea when I was sleeping on my side , thanks for any response

    • Hi Sarah, I am very glad to hear that you found the article helpful. Altitude does affect atmospheric pressure which can affect your CPAP pressure. Lots of machines have an automatic altitude adjustment already built into them and of course if you are using an auto adjusting CPAP machine (APAP) the machine would self adjust also. If you are uncertain you can always check your pressure against a manometer. Here is a link to one that we carry In my experience most sleep clinics are willing to test your machines pressure against their manometer.

      Humidity does not affect the efficacy of the CPAP therapy however, it can make it more comfortable for your body to take the therapy. Age does not play a role in affecting sleep apnea as anyone can have sleep apnea including infants and adults of any age.

    I use and have8 used a clap for years and I agree that alcohol does not work well. I also agree that sleeping on your side is much better when and if you use a clap machine. Your sleep cycles will be much much better.

    I only disagree with one word in this article. Sleep apnea is not a disease, it is a condition. I have been a CPAP user since July 12, 1998.

  5. In addition to a full time job, I teach an aerobics class 4 times a week. Three of the classes are at night and I have a hard time coming down. So I would have a drink or two to relax before going to bed. I have noticed that I am still very tired during the day. Any suggestions on how to wind down after teaching so I am not up until midnight when I need to be up at 4:30am?

    • Hi Terry, I am sorry to hear that you have been feeling tired during the day. Do you think your tiredness is in direct correlation to sleep apnea, or do you only experience tiredness the day after you’ve had a drink, or two to unwind? If you think you might have sleep apnea, we encourage you to speak with your doctor for a sleep study.

      If you find that you are only tired the day after you’ve had a couple of drinks to unwind after your classes, then you may find the article below helpful.

      Have a great day!

  6. I am feeling very tired during the day post using the CPAP machine with proper sleep during the night for at least 7-8 years. AHI levels are below 3 and no leakages. I have been using this for last 10 days. Please suggest what could be the reason.

    • Hi TC, I am sorry to hear that you are feeling tired after using your machine. I would recommend that you speak with your doctor regarding your feelings of tiredness to see if they are able to view your data and determine what is going on for you.

      We wish you the best!

  7. If I even have one drink my sleep apnea is much much worse.
    I recently went on an 8 day vacation anf drank one drink per day.
    I have been home for 4 days and am still exhausted.
    At one point I was sleeping at 6000 or so feet above sea level and my sleep was over 10 times worse than normal.
    The CPAP machine does not work for me. I use an alarmed oximeter by bodimetrics which helps a little. The device allows me to see my O2 drops on my phone which I like.

    Hi all, I’m curious, is it ok to drink alcohol if you are using the CPAP machine for sleep apnea ? Admittedly, i have the condition, n have drunk alcohol quite a number of times since being on the machine, but i’ve heard mixed reviews, some say drink whatever you want, some say not atol ect, so can anybody please tell me thanx ?????

    • Hi Scott, alcohol and Sleep Apnea do not mix well. Drinking alcohol can actually increase apneic events and their duration, worsening your Sleep Apnea symptoms.

      If you plan to drink, it’s best to use an auto-titrating (APAP), this machine will adjust the pressure to what you need on a breath by breath basis. Also, it is recommended that you stop drinking at least two hours before you plan to sleep, and try sleeping on your side.

      Please see the link below to see what other CPAP users are saying on our site.

      For further questions, or concerns, we can be reached at: 1-800-356-5221.

      Have a great day!

  9. When you get on a CPAP machine…
    you’re basically on a life support machine.
