CPAP therapy is a successful treatment for people with obstructive sleep apnea (OSA). There is a range of CPAP machines and masks available, and we look at some that are suitable for side sleepers.

Some of the best CPAP masks for side sleepers

Obstructive sleep apnea (OSA) is a sleep disorder that occurs when a person’s airways become blocked. People with OSA may temporarily stop breathing in their sleep. It is a serious condition that requires treatment.

This article describes how CPAP therapy works and outlines some of the best mask options for side sleepers.

CPAP masks are a method to reduce symptoms of OSA.

Often, the airways become blocked because soft tissues in the throat collapse and close when a person relaxes during sleep. According to the American Sleep Apnea Association, sleep apnea is as common as type 2 diabetes, affecting about 18 million people in the United States.

Anyone can have sleep apnea, but males over 40 who have overweight are more likely to have the condition.

Continuous positive airway pressure (CPAP) therapy is the most common treatment for OSA.

Here are a few CPAP mask options for side sleepers.

A CPAP mask should fit comfortably, but it may take time for a person to get used to sleeping while wearing one.

There is a range of masks to suit different people. People who breathe through their mouths while asleep may choose a full mask or one with a strap, while nose-breathers may prefer nasal masks or models with nose cushions.

Many people stop using CPAP because they find it hard to sleep wearing a mask. This can be detrimental to health. Choosing a mask that does not interrupt a good night’s sleep is a crucial part of CPAP therapy compliance.

People who sleep on their side may encounter issues with CPAP therapy. If their pillow is too soft, the fabric can block mask ports, which can be dangerous.

Side sleepers may also experience mask movement during the night. Some masks also create uncomfortable pressure on the cheek for side sleepers.

Picking the right mask is a personal process and may require experimentation.

If side sleepers experience issues with mask-wearing, they can try special CPAP pillows. These pillows accommodate people wearing CPAP masks and help side and stomach sleepers find a comfortable sleep position.

The American Lung Association state that CPAP is a very successful treatment option for people with obstructive sleep apnea.

CPAP therapy involves wearing a mask attached to a device that pumps air into a person’s airway while they sleep. Straps keep the mask in place.

CPAP machines help ensure a steady flow of air enters a person’s airway. The air pressure from the device keeps the airway open and prevents it from collapsing in on itself.

CPAP machines do not cure sleep apnea. They help ease symptoms, but they do not address the root cause of the problem.

Typically, people purchase CPAP machines and accessories from medical supply companies.

According to a 2020 article, people with the following conditions may be unsuitable for CPAP therapy:

  • anxiety
  • those in a coma or who are unable to breathe on their own
  • facial burns
  • those recovering from face, throat, or stomach surgery
  • nausea and vomiting

While CPAP therapy is the primary treatment for sleep apnea, it does not cure the condition.

In addition to a CPAP machine, the American Lung Association recommends the following lifestyle changes:

  • losing weight
  • quitting smoking
  • avoiding certain sleep positions (e.g., lying on one’s back)
  • avoiding alcohol and other sedatives

An article in Neurology Clinical Practice indicates that mandibular advancement (MA) devices are an alternative to CPAP machines for people with mild sleep apnea.

An MA fits inside a person’s mouth and moves the jaw forward to help prevent airway obstruction.

Here we answer some common questions about these products.

Can I sleep on my side with a CPAP mask?

People can sleep on their side while wearing a CPAP mask.

Some companies manufacture masks that may be more suitable for side sleepers. These masks may be less likely to cause discomfort due to the product pressing into the skin while a person is sleeping.

What are the different types of CPAP masks?

There are three types of CPAP masks: nasal pillow, nasal mask, and full face mask.

Nasal pillow masks have cushions that rest on the entrance to the nostrils. Nasal masks cover the nose, and a full face mask covers both the nose and the mouth.

Can I use a nasal CPAP mask if I breathe through my mouth?

People who tend to breathe through their mouths while sleeping may prefer to use full face masks.

Full face CPAP masks reduce the amount of air leakage and may return better results.

OSA is a potentially dangerous sleep condition that can cause a range of complications, including heart problems, fatigue, and headache.

CPAP is an effective treatment for OSA symptoms. However, finding the correct mask is an essential factor in sticking to this type of therapy.
