Sleep Apnea and Migraines: What’s the Link?

Sleep Apnea and Migraines: What’s the Link?

A migraine is characterized by headaches lasting at least 4 hours and potentially more than a day. Most often, the pain is unilateral—affecting only one side of the head—and comes with a pulsing sensation of varying intensity. Do you often wake up with a terrible headache? If this happens frequently, your sleep might be to blame. Sleep, sleep apnea, and migraines – what’s the connection? Migraine and sleep deprivation often go hand in hand!

Let’s explore the link between sleep apnea and chronic headaches—an often overlooked and very debilitating complication.

When Sleep Apnea Triggers Migraines

Sleep apnea doesn’t just disrupt your nights. There’s a known relationship between sleep apnea and headaches. It's not uncommon for people with sleep apnea to also suffer from persistent headaches. So, how are these two issues connected?

Lack of Oxygen in the Brain

During sleep apnea episodes, the brain is deprived of oxygen. Even if this deprivation is brief, it causes the blood vessels in the brain to dilate. As a result, people often wake up with a headache, feeling pressure as if their temples are caught in a vice. Some studies highlight this connection between sleep apnea and migraines.

Fragmented Nights = Disturbed Sleep = Migraines

The frequent micro-awakenings caused by sleep apnea disrupt the natural sleep cycles. This sleep fragmentation is well known to trigger migraines. Patients suffering from both sleep apnea and migraines generally experience poor sleep quality. This is often confirmed during a polysomnography test.

Types of Headaches Related to Sleep Apnea

There are different types of headaches, and sleep apnea can be the root cause of many of them. Each type has its own features. Here’s a summary of the most common ones:

Morning Headache Upon Waking Up

This is the most common headache associated with sleep apnea. It is often characterized by:

  • A dull, diffuse pain

  • A feeling of pressure throughout the head

  • An intensity that gradually decreases after waking

When Apnea Worsens Migraine Attacks

If you suffer from migraines, it’s important to know that sleep apnea can increase the frequency and intensity of headaches. Migraine patients who also suffer from sleep apnea often report:

  • More frequent migraine attacks

  • More intense pain

  • Reduced effectiveness of usual treatments

One study even suggests that patients with sleep apnea are 2.5 times more likely to suffer from migraines.

How to Identify the Link Between Sleep Apnea and Migraines: Symptoms

There are signs that can help you recognize the connection between sleep apnea and migraines. These include:

Signs to Watch For:

  • Waking up with a headache that eases during the morning

  • Loud snoring and possible breathing pauses during sleep (often noticed by a partner)

  • Constant fatigue, even after what seems like a normal night’s sleep

  • Headaches accompanied by a dry mouth upon waking

When Should You See a Specialist?

If you have several of the symptoms listed above, you should consult a specialist. They can:

  • Evaluate your symptoms thoroughly

  • Suggest a sleep study to confirm sleep apnea

  • Recommend an appropriate treatment

How to Relieve Migraines and Improve Sleep

In general, when sleep apnea is treated, headaches tend to diminish. So, it's essential to get a proper diagnosis. Here are some treatment options:

CPAP Therapy (Continuous Positive Airway Pressure)

CPAP is the gold standard for treating sleep apnea. It keeps the airways open during the night and helps:

  • Reduce apnea episodes

  • Improve oxygen flow to the brain

  • Lower the frequency and intensity of headaches

Alternatives to CPAP

If CPAP isn’t well tolerated, other options include:

  • Intranasal devices or mandibular advancement splints

  • Surgery on the upper airway (in specific cases)

  • Lifestyle changes: weight loss, quitting smoking, reducing alcohol consumption—especially in the evening

Conclusion

As you can see, sleep apnea and chronic headaches are often closely connected. Together, they form a harmful duo that affects quality of life. However, with a proper diagnosis and tailored treatment, this vicious cycle can be broken—offering significant relief from migraines.

It’s important to discuss your headaches with your doctor, as they could lead to the discovery of undiagnosed sleep apnea.

Among the devices that help clear the airways and improve sleep, Back2Sleep offers an intranasal device that could help some patients. Don’t hesitate to contact them for more information.

A better night’s sleep is the key to a life free from these painful and unpleasant headaches.

FAQs

Can sleep apnea cause migraines?

Yes. Repeated micro-awakenings caused by sleep apnea disrupt natural sleep cycles. This sleep fragmentation is a known migraine trigger.

What is a “sleep migraine”?

Hypnic headaches occur during sleep. The pain is often described as a pulsing pressure in sync with the heartbeat. It may happen once or several times per night, but always while sleeping.

What triggers a migraine?

Migraine pain results from the dilation of cerebral blood vessels, particularly the arteries of the meninges (the membranes protecting the brain). This dilation is caused by abnormal stimulation of nerves connected to these vessels.

What are the effects of sleep apnea on the brain?

Sleep apnea often causes issues with concentration, memory problems, and mood disorders. These effects prevent individuals from functioning effectively in daily life.
