Waking up with a headache is never a great way to start the day, but for people with sleep apnea, morning headaches are a common and frustrating symptom. If you regularly experience headaches when you wake up, your body may be signaling that something is wrong with your breathing during sleep.

Let’s explore how sleep apnea causes headaches, what you can do to prevent them, and how respiratory support can help improve your sleep quality—and your mornings.

How Does Sleep Apnea Cause Headaches?

Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. These pauses in breathing, known as apneas, can last from a few seconds to a minute or more, reducing oxygen levels in the blood. When this happens, carbon dioxide builds up, leading to a condition called hypoventilation—which can trigger headaches.

Here’s how it happens:

  • Oxygen Deprivation – When your body doesn’t get enough oxygen during sleep, blood vessels in the brain dilate to compensate, causing a headache.
  • Carbon Dioxide Build-Up – As breathing slows or stops, excess carbon dioxide remains in the bloodstream, leading to vascular changes that can result in morning headaches.
  • Sleep Disruptions – Frequent awakenings throughout the night prevent deep, restorative sleep. Poor sleep quality itself is a well-known trigger for tension headaches and migraines.

Are Sleep Apnea Headaches Different from Other Headaches?

Yes—sleep apnea headaches are typically:

  • Present first thing in the morning
  • Felt on both sides of the head
  • Described as a dull, pressing pain rather than a throbbing sensation
  • Short-lived, usually improving within an hour or two after waking up

Unlike migraines, these headaches aren’t usually accompanied by nausea, sensitivity to light, or visual disturbances.

How to Treat and Prevent Sleep Apnea-Related Headaches

The good news? Treating sleep apnea can often eliminate morning headaches altogether. Here’s what you can do:

  1. Use a CPAP or BiPAP Machine: Continuous Positive Airway Pressure (CPAP) and Bilevel Positive Airway Pressure (BiPAP) machines keep your airway open during sleep, ensuring steady oxygen flow and preventing breathing interruptions. Many people notice a dramatic reduction in morning headaches once they start using CPAP therapy.
  2. Improve Sleep Positioning: Sleeping on your back can make sleep apnea worse. Try sleeping on your side to keep your airway open and reduce apnea episodes.
  3. Maintain a Healthy Weight: Excess weight, especially around the neck, can contribute to airway obstruction. Even a small amount of weight loss can improve breathing and reduce sleep apnea severity.
  4. Practice Good Sleep Hygiene: Establishing a regular sleep schedule, avoiding alcohol before bed, and keeping your bedroom cool and dark can help improve sleep quality and lessen sleep apnea symptoms.
  5. Seek Respiratory Support for Hypoventilation: If your headaches persist, they may be a sign of chronic hypoventilation, meaning your body isn’t getting enough oxygen even while awake. Respire Home Care specializes in helping patients with sleep apnea and respiratory conditions find the right support, from oxygen therapy to non-invasive ventilation options.
