Understanding sleep apnea and the role of pillows
To understand how the right pillow can help with sleep apnea, let’s first look at what the condition is and explore its connection to your breathing and sleeping posture.
What is sleep apnea?
Obstructive sleep apnea (OSA) is the most common type of sleep-disordered breathing. It happens when the muscles in the back of your throat relax too much during sleep, causing the soft tissues to collapse and physically block your airway.1 These pauses in breathing, called apneas, can happen many times per hour. The lack of oxygen forces your brain to briefly wake you up to restart your breathing. These awakenings are so brief you likely won’t remember them in the morning, but they stop you from getting the deep, restorative sleep your body needs.2
Constant disruptions to your sleep can affect your quality of life and lead to noticeable symptoms. Common signs include:1, 2
- Excessive daytime sleepiness that interferes with work or daily activities
- Frequent, persistent snoring, gasping or choking sounds that keep you or your loved ones awake
- Waking up with a morning headache, dry mouth or sore throat
- Difficulty concentrating, memory problems and feeling irritable during the day
Over time, untreated sleep apnea and other sleep disorders may increase the risk of other serious health conditions, including high blood pressure, depression, heart disease and Type 2 diabetes.3
The connection between sleep position and sleep apnea
Your sleeping position can directly affect the severity of your sleep apnea. Sleeping on your back often makes symptoms worse because gravity naturally pulls your tongue and soft tissues down, making an airway blockage more likely.4 Many people have something called positional obstructive sleep apnea, where their breathing issues happen mostly when sleeping on their back. For this reason, side sleeping can be recommended as a lifestyle change to help keep the airway open.5
How pillows can influence sleep apnea symptoms
Your pillow’s main role is to support your head and neck. This promotes healthy, neutral spinal alignment that’s essential for optimal breathing during sleep.6, 7 An unsupportive pillow can cause your head to tilt in a way that may block the airway, similar to bending a straw. Therefore, a well-designed pillow can act as a complementary approach to your overall management plan. Just keep in mind that a pillow is a supportive tool, not a standalone medical treatment for sleep apnea.6
Types of pillows for sleep apnea management
Pillows designed to help people with sleep apnea come in several forms, each with unique features to address specific needs.
Wedge pillows
A wedge pillow is a large, triangular foam cushion that elevates your entire upper body. Research suggests that sleeping on an incline may help reduce breathing disruptions for people with obstructive sleep apnea (OSA). And the amount you elevate your head doesn’t have to be dramatic. In fact, some people may benefit at a mild head-of-bed elevation of just 7–8 degrees.8
What’s more, an elevated sleeping position can also help people who experience acid reflux, a condition that can worsen sleep apnea symptoms.9, 10 It may take a few nights to get used to the new sleeping angle, so be patient with the adjustment period.
CPAP-compatible pillows
CPAP-compatible pillows may help make CPAP therapy feel more comfortable and easier to adjust to. They feature special cutouts and indentations designed to create space for your mask, frame and tubing. The design stops a pillow from pushing your mask out of place, which is a common cause of air leaks or pressure on your face. Limited but supportive clinical evidence suggests these designs can improve comfort and user preference, but effects on how well it works to support treatment and prevent leaks are modest in small trials.11, 12
Because they enhance comfort and help prevent disruptions, these pillows may help you feel more comfortable when using your CPAP. They’re often made from supportive memory foam and are designed to work with all major mask types.
Cervical and contour pillows
Also known as orthopedic pillows, cervical pillows have a distinct wave-like shape that follows the natural curve of your head, neck and shoulders. The contoured design provides targeted support to your neck, helping to maintain proper alignment and keep your airway from narrowing.7, 13 Some studies suggest that the improved posture from a cervical pillow may also help reduce the intensity of snoring.14
Specialty sleep apnea pillows
Specialty sleep apnea pillows include other innovative designs aimed at improving sleep posture. For example, body pillows are long cushions you can hug. They support your back and hips, helping side sleeping feel more stable and secure, which can discourage you from rolling onto your back.
Other positioning pillows have built-in bumpers or anti-snore features that make sleeping on your back more uncomfortable, so you can train yourself to stay on your side throughout the night. Unlike conventional pillows, which provide general comfort, these specialty pillows have a targeted function to promote a healthier sleep posture.5, 15
