Can Anxiety Cause Sleep Apnea?

Sleep apnea is a significant sleep disorder, and one that can actually hurt your health. Those that suffer from sleep apnea rarely even realize that they have this disturbance, although some end up waking up in the middle of the night with severe panic attacks.

Some of the causes of sleep apnea are known. Others are much less clear. Many people have wondered in the past if sleep apnea may be a symptom of anxiety. We'll explore that idea in this article.

Sleep Apnea = Anxiety?

Apnea is a complicated disorder, and you need to discuss it with your doctor. You should also focus on ways to decrease your anxiety once and for all. Take my 7 minute anxiety test to learn more.

Anxiety and Sleep Apnea

Anxiety does cause many physical symptoms, and some of those symptoms do occur while you sleep. From tooth grinding to muscle tension to nighttime anxiety, there are countless examples of physical symptoms that affect you while you sleep, so it's possible that sleep apnea is one of them. Take my anxiety test to learn more about your type of anxiety.

According to most available research, it's unlikely that anxiety causes sleep apnea. There have been some studies in the past that have linked apnea to a stress response, so it's possible that there is some small link between anxiety (which causes stress) and the development of sleep apnea, but it appears to be unlikely.

Why Do Many People With Anxiety Have Sleep Apnea?

You should first find out if you even have sleep apnea. Make sure you're not self-diagnosing. People wake up in the middle of the night for a variety of reasons. Sleep apnea is a very specific condition, and not something that you can easily diagnose on your own.

But if you know that you have sleep apnea, there are actually several reasons that those with apnea have anxiety. These include:

  • Apnea Causes Anxiety Sleep apnea can actually cause significant anxiety and panic attacks. It interrupts sleep and leads to sleep debt, which makes it harder for the brain to cope with stress. It also causes stress on the mind and body because apnea prevents you from recovering after sleep. Your heart and blood pressure may also be affected, leading to additional physical symptoms. Apnea can cause anxiety, and increase anxiety in those that already have it.
  • Regular Apnea It's believed that sleep apnea is caused by being overweight. But while obesity does seem to contribute to the development of sleep apnea - especially obstructive sleep apnea - it is not the only cause, and it is considered a myth that one must be overweight to have apnea. Thus if you believed that your apnea must be caused by anxiety because you're not overweight, you may simply have sleep apnea.
  • Similar Issues While obesity may not be the only cause of sleep apnea, it is often a contributing factor and certainly one of the most common causes. Obesity is linked to inactivity, and inactivity may also cause anxiety. It's possible that anxiety isn't causing sleep apnea, but instead sleep apnea and anxiety are developing together.

Some research has theorized that anxiety may cause sleep apnea to be worse as well, although it's not entirely clear why and few studies have actually provided such a link.

Some people may develop nighttime panic attacks as a result of their sleep apnea as well. These panic attacks are often triggered by the way the heart reacts to the breathing problems sleep apnea causes. It's not uncommon to feel like your panic attacks are causing that apnea, when in fact it's the other way around.

So it doesn't appear that sleep apnea is caused by stress or anxiety. It should be noted that very few studies have tried to link the two conditions, and because sleep apnea is known to cause anxiety it's difficult for researchers to determine which came first.

It's clear that apnea is a very common cause of panic attacks and anxiety. It's also known that anxiety can affect the body in many different ways, as well as react poorly to the effects of apnea. Rather than consider the two similar conditions, they should be treated separately where you will follow your doctor's advice to treat your apnea and make sure you're committed to a long term treatment option for anxiety.

I've helped many people suffering from both apnea and anxiety. Start with my free 7 minute anxiety test now to gain greater insight into your anxiety. Then partner that with your doctor's apnea recommendations and you're bound to find relief.

Frequently asked questions

What do I do next?

We really suggest people take our anxiety test - it provides a breakdown of how your particular anxiety manifests itself.

I have a question about anxiety or mental health - can you answer it?

Please don't send us questions about your specific mental health issues. They should really be answered by a professional who knows your history.

We are a small team, and it is simply impossible for us to handle the volume of people who need their questions answered. Our anxiety test was created exactly for that purpose - so that people can work on their mental health problems themselves. Please make use of it.
