Can Sleep Apnea Cause Headaches?

Sleep apnea is a common sleep disorder that disrupts your breathing while you sleep. But can sleep apnea cause headaches? If you’re waking up with throbbing temples, you might be wondering about this connection. This comprehensive blog post will explore the link between sleep apnea and headaches, providing the information you need to tackle this issue.

Understanding Sleep Apnea: Can Sleep Apnea Cause Headaches?

Sleep apnea causes your breathing to stop and start repeatedly while you’re asleep. This condition can lead to numerous health issues, including headaches, especially in the morning. According to the American Migraine Foundation, there’s a significant link between sleep apnea and headaches. But why does this happen?

Can Sleep Apnea Cause Morning Headaches?

The short answer is yes. Sleep apnea can cause morning headaches. Sleep apnea disrupts sleep, reduces oxygen levels, and increases carbon dioxide levels. This fluctuation in gases can cause blood vessels in your brain to dilate, leading to what’s known as a vascular headache.

What Does a Sleep Apnea Headache Feel Like?

A sleep apnea headache often feels like a dull, constant ache on both sides of the head. The pain typically occurs upon waking and dissipates within a few hours. These headaches can often be mistaken for tension headaches due to their similar characteristics.

Sleep Apnea Headache Location

Sleep apnea headaches are usually bilateral, meaning they affect both sides of your head. The pain is often generalized and doesn’t focus on one specific area.

Can Sleep Apnea Cause Tension Headaches?

Sleep apnea can indeed lead to tension headaches. The interrupted sleep and low oxygen levels associated with sleep apnea can increase your body’s stress response. This increased stress can cause muscle contractions in your head and neck, leading to tension headaches.

Can Sleep Apnea Cause You to Wake Up with a Headache?

Yes, sleep apnea can cause you to wake up with a headache. The headache usually occurs in the morning due to the prolonged effects of oxygen deprivation and increased carbon dioxide levels at night.

Sleep Apnea Headache Treatment

Treating sleep apnea headaches involves addressing the root cause – the sleep apnea itself. Common treatments include:

  1. Continuous Positive Airway Pressure (CPAP): This is the most common treatment for sleep apnea. It involves wearing a mask over your nose and/or mouth while you sleep, which provides a constant stream of air to keep your airways open.
  2. Lifestyle Changes: This includes losing weight if you’re overweight, quitting smoking, and avoiding alcohol and certain sleeping pills.
  3. Oral Appliances: These devices, designed to keep your throat open, can be made by a dentist or orthodontist.

Remember, if you suspect you have sleep apnea, it’s important to seek medical advice. The American Academy of Sleep Medicine can provide more information on sleep apnea diagnosis and treatment options.

So, can sleep apnea cause headaches? Absolutely. However, with the right diagnosis and treatment plan, you can manage your sleep apnea, reduce the occurrence of headaches, and wake up feeling refreshed and ready to face the day.

The Impact of Sleep Apnea on Overall Health

Sleep apnea does more than just disrupt your sleep and cause headaches. If left untreated, it can have far-reaching effects on your overall health. Sleep apnea has been linked to a variety of health conditions including:

  • Heart Disease: Sleep apnea is associated with a higher risk of heart disease due to the strain caused by sudden drops in blood oxygen levels during sleep.
  • High Blood Pressure: Waking up frequently during the night can cause hormonal systems to go into overdrive, leading to high blood pressure.
  • Type 2 Diabetes: Sleep apnea is common among people with type 2 diabetes, possibly due to obesity, a common factor in both conditions.
  • Mental Health Issues: Sleep deprivation from sleep apnea can contribute to mood swings, depression, and anxiety.

Identifying the Different Types of Headaches

Understanding the type of headache you’re experiencing can help you manage it effectively. 

Here are the common types of headaches:

  • Tension Headaches: These are often described as a constant pressure or ache on both sides of the head or at the back of the head and neck. Stress and muscle strain commonly trigger them.
  • Migraines: Migraines cause severe, throbbing pain, usually on one side of the head, accompanied by other symptoms like nausea, vomiting, and sensitivity to light and sound.
  • Cluster Headaches: These are intensely painful headaches that occur in clusters or cycles. The pain is usually situated around one eye.
  • Sinus Headaches: These are associated with a feeling of deep and constant pain in your cheekbones, forehead, or the bridge of your nose. They usually occur when sinuses become inflamed, often due to an infection or allergies.
  • Sleep Apnea Headaches: As discussed earlier, these headaches are typically dull, affect both sides of the head, and occur upon waking.

Lifestyle Changes to Manage Sleep Apnea

While medical intervention may be necessary in some cases, certain lifestyle changes can also help manage sleep apnea:

  • Maintain a Healthy Weight: Excess weight increases the likelihood of airway obstruction and narrowed airway passages. Maintaining a healthy weight can help alleviate these issues.
  • Exercise Regularly: Regular physical activity can help you maintain a healthy weight and promote better sleep.
  • Quit Smoking: Smoking can increase inflammation and fluid retention in the upper airway, worsening sleep apnea.
  • Avoid Alcohol and Sedatives: These substances can relax the muscles in the throat, interfering with breathing.
  • Sleep on Your Side: Lying on your back can cause your tongue and soft palate to rest against the back of your throat, blocking the airway. Sleeping on your side can help prevent this.

Remember, if you’re experiencing frequent morning headaches or suspect you have sleep apnea, consult with a healthcare provider. They can provide the necessary diagnosis and treatment options to help you get a good night’s sleep.

How to Differentiate Between a Sleep Apnea Headache and a Migraine

While both sleep apnea headaches and migraines can cause significant discomfort, there are distinguishing characteristics to help identify each.

Sleep Apnea Headaches:

  • These headaches often occur upon waking in the morning.
  • The pain is typically a dull ache and usually affects both sides of the head.
  • Sleep apnea headaches usually resolve within a few hours after waking.
  • They are often accompanied by other symptoms of sleep apnea, such as daytime sleepiness, snoring, or abrupt awakenings accompanied by shortness of breath.


  • Migraines can occur at any time and are not necessarily linked to sleep or waking up.
  • The pain is usually throbbing or pulsating and often affects one side of the head, although it can affect both.
  • Migraine attacks can last from hours to days.
  • Other symptoms like nausea, vomiting, and sensitivity to light and sound often accompany migraines.

Remember, getting a proper diagnosis from a healthcare provider is crucial if you are experiencing frequent headaches.

Understanding the Long-term Consequences of Untreated Sleep Apnea

Untreated sleep apnea doesn’t just cause immediate issues like headaches and daytime fatigue; it can also have long-term consequences on your health.

  • Heart Problems: The sudden drops in blood oxygen levels that occur during sleep apnea episodes can increase blood pressure and put a strain on the cardiovascular system, leading to conditions like heart disease and arrhythmias.
  • Type 2 Diabetes: Sleep apnea is associated with insulin resistance, a precursor to type 2 diabetes.
  • Metabolic Syndrome: This cluster of conditions — including high blood pressure, abnormal cholesterol levels, high blood sugar, and excess body fat around the waist — is linked to sleep apnea.
  • Liver Problems: People with sleep apnea are more likely to have abnormal results on liver function tests, and their livers are more likely to show signs of scarring (nonalcoholic fatty liver disease).
  • Cognitive Issues: Chronic sleep deprivation can affect your ability to think, concentrate, and make decisions, and it might even lead to mood swings and depression.

You must seek medical help if you suspect you have sleep apnea. The condition is treatable, and treatment can significantly reduce your risk of these serious complications.

The Mechanism Behind Sleep Apnea-Induced Headaches

Sleep apnea, particularly obstructive sleep apnea (OSA), can lead to headaches due to the intermittent cessation of breathing during sleep. It can cause significant changes in oxygen and carbon dioxide levels in the blood, leading to vasodilation or constriction of blood vessels in the brain, resulting in a headache. This type of headache often occurs in the morning upon waking and typically subsides within a few hours.

The Connection Between Sleep Apnea and Migraines

An emerging body of research, such as this study published in the American Migraine Foundation, suggests a possible link between sleep apnea and migraines. Sleep apnea can cause sleep disturbances, a recognized trigger for migraines. Additionally, the oxygen deprivation that occurs during sleep apnea episodes might trigger migraines in susceptible individuals.

Managing Headaches Associated with Sleep Apnea

Headaches caused by sleep apnea are typically managed by treating the underlying sleep disorder. It can involve lifestyle changes like weight loss, smoking cessation, and avoiding alcohol and sedatives. Using a CPAP (Continuous Positive Airway Pressure) machine to regulate breathing during sleep is also a common treatment. In some cases, medications may be prescribed to alleviate headache symptoms.

The Link Between Sleep Apnea and Other Neurological Disorders

Sleep apnea has been associated with several other neurological disorders, including stroke and Alzheimer’s disease. The intermittent hypoxia (low oxygen levels) caused by sleep apnea can lead to various neural changes and damage, potentially increasing the risk of these disorders. Regular monitoring and management of sleep apnea is essential to minimize these risks.

The Role of CPAP in Treating Sleep Apnea and Associated Headaches

CPAP therapy is the frontline treatment for moderate to severe cases of sleep apnea. A CPAP machine keeps the airway open and prevents breathing interruptions during sleep by providing a steady stream of air. This therapy can effectively alleviate sleep apnea symptoms, including associated headaches. Regular use of CPAP machines can dramatically improve the quality of life for individuals with sleep apnea.

Sleep apnea can indeed cause headaches, and managing the condition effectively is crucial in preventing and reducing these headaches. It’s always important to consult with healthcare professionals if you’re experiencing regular headaches, especially if you also have symptoms indicative of sleep apnea.
