Obstructive Sleep Apnea (OSA) typically coincides with loud snoring or gasping for air, but you may not be aware that there are many other signs and symptoms of OSA that may not always be as obvious. 

For example, you might also experience chronic dry mouth when you wake up because you’re being forced to sleep with your mouth open. You might also wake up several times throughout the week with persistent, increasingly worse headaches or migraines.

Which Type of Headache Do You Have?

There are numerous types of headaches and they can be caused by a myriad of reasons. The most common culprits are migraine headaches, cluster headaches, tension headaches, hypnic headaches, and paroxysmal hemicrania.

• Migraine Headaches cause an intense throbbing sensation localized to one area and can cause sensitivity to light and sound. These headaches are often caused by dehydration, poor sleep, hormonal changes, stress, and certain foods and drinks.
• Cluster Headaches are more severe and occur in "clusters" or groups over extended periods. They usually affect one side of the head and can cause pain behind the eye, as well as a runny nose or watery eyes.
• Tension Headaches are the most common type of morning headache that feels like a tight band is gripping your whole head. These can be caused by stress, anxiety, or sleeping with a neck pillow that's too high.
• Hypnic Headaches are often referred to as "alarm clock headaches" because they usually occur around the same time of the night, during the REM stage of sleep. The pain is often enough to wake someone out of a sound sleep.
• Paroxysmal Hemicrania is a headache with intense throbbing and claw-like pain to the side of the face, in or around the eye, or the back of the neck.

Now that you know the different types of morning headaches, let’s review one of what may be causing them!

Sleep Apnea and Oxygen Deprivation

Sleep apnea is a disorder that not only affects the quality of your sleep but also your ability to breathe. This means sleep apnea attacks your body on two fronts: by depriving you of the oxygen your cells and tissues need, and by depriving your mind and body of the rest they need to properly recuperate.

Sleep apnea-induced fatigue is one of the most common results of the disorder and, combined with oxygen deprivation, can contribute to debilitating morning headaches and migraines.

It's More Than Just a Headache!

Sleep apnea often comes with a host of other negative impacts on your health and well-being besides fatigue. Headaches and exhaustion may be immediate side effects of oxygen deprivation, but longer-term effects can include increased risks of heart disease, chronic cardiovascular problems, stroke, mental health disorders, and more. To avoid these risks, you should seek a sleep apnea assessment and appropriate treatment, if necessary, as soon as you notice related symptoms.
