If you wake up with head pain most mornings, your body may be sending you an important message. Many people with obstructive sleep apnea (OSA) don’t realize that their nighttime breathing problems could be causing daytime head pain. Understanding the link between sleep apnea and headaches can help you get the right treatment and feel better.
Before exploring how sleep apnea affects head pain, it helps to understand the difference between headaches and migraine attacks.
Headaches are one of the most common health complaints, and they typically cause pain or pressure in the head or face. There are over 150 different types of headaches, which are classified by the type of pain, location, severity, and frequency.
Migraine is different. It’s a neurological condition that’s more severe than a headache. A migraine attack often causes severe, throbbing pain on one side of the head. It can last for a few hours or even a couple days.
Symptoms of migraine attacks are different for everyone, but they’re sometimes accompanied by nausea, vomiting, and sensitivity to light. Some people experience warning signs called aura before a migraine attack, which can include vision changes or tingling in their arms or legs. Migraine also makes it difficult to do usual activities.
Obstructive sleep apnea happens when the muscles in your throat relax during sleep and block your airway. This blockage causes your breathing to stop and start repeatedly throughout the night. Each time your airway closes, your oxygen levels drop and carbon dioxide builds up in your blood.
These breathing interruptions, or apneas, can trigger a chain reaction in your body. When oxygen levels fall too low, blood vessels in the brain expand to try to get more oxygen. This expansion builds up pressure, which can create a throbbing sensation and develop into a headache.
Headaches caused by sleep apnea usually happen in the morning after sleep apnea episodes, but some types can occur during sleep. They can last anywhere from a few minutes to hours and cause different symptoms such as pain behind or near the eye, drooping eyelids, and stuffy nostrils.
Research shows that 29 percent of people with OSA report frequently waking up with headaches. Another study found that roughly 33 percent of those with OSA experience headaches, including morning headaches and tension headaches.
The relationship between sleep apnea and migraine is a little more complex. While obstructive sleep apnea doesn’t directly cause migraine, it can make migraine attacks worse. Chronic migraine can also increase the risk of sleep disorders like sleep apnea.
About 8 percent of people with OSA also experience migraine. One reason this may happen is because of awakenings during the night caused by sleep apnea episodes. Poor sleep quality can cause fatigue and daytime drowsiness, which could ultimately trigger migraine symptoms.
Several warning signs may suggest your headaches might be connected to sleep apnea. The most important clue is when you experience pain. If you wake up and feel like you have pressure in your head but it improves within a few hours of rising, it may be linked to sleep apnea.
If you’re experiencing unexplained headaches, watch for other signs, including:
You should pay attention to how you feel during the day, too. Sleep apnea may be affecting your quality of sleep if you:
Additionally, sometimes you might notice that you wake up in the morning with a sore throat or dry mouth.
If you believe your headaches may be linked to sleep apnea, there’s good news. Treating sleep apnea often significantly reduces headache frequency.
Talk to your doctor if you think sleep apnea might be the culprit of your headaches. They can refer you to a sleep specialist who will likely recommend undergoing a sleep study. This test, called a polysomnography, monitors your breathing, oxygen levels, brain activity, and body movements during sleep to diagnose sleep apnea.
A sleep study happens overnight, either at a sleep center or sometimes at home with portable equipment. The results show how many times per hour your breathing stops or becomes too shallow. Doctors measure this with the apnea-hypopnea index (AHI), and an AHI of five or more events in one hour indicates sleep apnea.
If your healthcare team confirms a diagnosis of sleep apnea, there are a few treatment options you can consider to improve sleep and possibly your headaches.
The most common and effective treatment for sleep apnea is continuous positive airway pressure (CPAP) therapy. A CPAP machine delivers steady air pressure through a mask you wear over your nose or mouth while you sleep. This air pressure keeps your airway open so you can breathe normally throughout the night.
Research shows that CPAP therapy can dramatically improve headaches in people with sleep apnea. One study from 2025 found that headaches improved in 78 percent of participants who used CPAP therapy regularly, while only 33 percent of those who did not do CPAP therapy saw improvement. CPAP therapy may also benefit those with migraine.
CPAP therapy can take some time adjusting to, and you may need to try different mask types until you find the one that works best for you.
Making healthy lifestyle changes can help you manage sleep apnea and may reduce headache frequency. Maintaining a healthy weight is particularly important, since excess weight, particularly around your neck, contributes to airway blockages during sleep. Losing 10 percent to 15 percent of body weight could significantly improve symptoms of sleep apnea. A study found that weight loss could also help alleviate migraine pain, frequency, and duration.
Other helpful changes include limiting alcohol consumption, especially in the hours before bed since alcohol relaxes throat muscles and makes airway blockages worse. You may also need to quit smoking, as smoking increases inflammation in the airways and leads to trouble breathing during sleep. Both alcohol and the nicotine inhaled from smoking may also trigger headaches and migraine attacks.
Your sleep position matters too. Sleeping on your back makes it easier for your tongue and soft tissues to block your upper airway. Instead, try sleeping on your side. Some people find it helpful to put pillows behind them to encourage side sleeping or even wear a device that prevents rolling onto the back during sleep.
For people who can’t tolerate CPAP or have mild to moderate sleep apnea, oral appliances, or mouth devices, may help. These devices reposition your tongue and jaw to keep your airway open during sleep. Studies show that oral appliance therapy improves headaches in people with mild to moderate OSA. Some people may benefit from surgery if other treatments aren’t as effective.
The connection between sleep apnea and head pain is real and important to address. Whether you’re experiencing morning headaches or migraine attacks, untreated sleep apnea could be making your symptoms worse. If you experience persistent head pain or other warning signs of sleep apnea, talk to your healthcare provider.
Remember, everyone’s situation is unique. Your doctor can help you understand whether your migraine attacks or headaches are connected to sleep apnea and recommend the best course of action. Taking steps to address sleep apnea not only reduces headaches and migraine attacks, it also helps you achieve better sleep and improve your overall quality of life.
