Continuous Positive Airway Pressure (CPAP) therapy is a life-changing treatment for individuals suffering from Obstructive Sleep Apnea. By delivering a steady flow of air, CPAP machines help keep airways open, ensuring uninterrupted breathing throughout the night.

However, while the therapy is crucial for managing sleep apnea, some users experience uncomfortable side effects—one of the most common being a sore throat. Waking up with a dry, scratchy, or painful throat can make your CPAP experience frustrating.

We'll explore why CPAP use can lead to a sore throat and provide effective solutions to alleviate and prevent this discomfort, providing valuable insights and practical tips for patients to overcome this common side effect, ensuring your CPAP therapy remains both effective and comfortable. 

Whether you're a seasoned CPAP user or a new CPAP user, just starting their therapy journey, understanding the root causes of throat irritation and learning how to alleviate it can make all the difference in enjoying a restful and rejuvenating sleep.


Why Does CPAP Cause a Sore Throat?

CPAP (Continuous Positive Airway Pressure) can cause a sore throat for several reasons, mainly related to airflow and equipment. Here are some common causes:

Dry or Cold Air

If the air delivered by the CPAP machine is not humidified, it can dry out the throat, leading to irritation or scratchy throat. Cold air, especially without heated tubing, can also cause discomfort in the throat. It’s common in people who are sensitive to dry environments or during winter months when the ambient air is already dry.

Air Leaks from the Mask

A poorly fitting CPAP mask can result in air leaks, which dry out the mouth and throat, causing soreness. CPAP Mask leaks are common, and typically occur due to the following reasons:

  • Improper mask fit
  • Worn-out mask components
  • Incorrect mask size or style
  • Impact of facial movements during sleep

High-Pressure Settings

CPAP devices are set to deliver a certain pressure to keep your airway open. If the pressure settings on your CPAP are too high, Pressurized air can cause excessive airflow through the throat, leading to dryness and soreness. But there are different factors which  can influence your need for a higher or lower pressure, like:

  • Weight Loss
  • Smoking
  • Drinking Alcohol
  • Regular Exercise
  • Seasonal Changes

If you feel that the pressure is too high, ask your doctor about adjusting the settings. Auto-adjusting CPAP machines (APAP) can be beneficial, as they automatically adjust the pressure based on your breathing patterns.

Mouth Breathing

People who breathe through their mouths while using a nasal mask can experience dry mouth and throat, as the airflow bypasses the humidification system. This can be due to:

  • Open-mouth sleeping with a nasal mask
  • Inadequate chin strap support
  • Nasal congestion forcing mouth breathing
  • Chronic Sinus or Respiratory Infections

If you frequently experience sinus infection, allergies, or chronic respiratory infections, CPAP use can sometimes aggravate these conditions. Blocked nasal passages can force you to breathe through your mouth, and any irritation in your respiratory system can be amplified by the continuous airflow. In these cases, the throat may become sore due to a combination of mouth breathing, air dryness, and existing respiratory inflammation, especially if the equipment is not properly cleaned.


Symptoms of CPAP-Induced Sore Throat

 Symptoms Description
Dryness in the Throat A feeling of excessive dryness, particularly in the morning.
Scratchy or Throat Irritation A raw or scratchy sensation in the throat that may persist throughout the day.
Soreness When Swallowing Mild to moderate discomfort when swallowing, often associated with dry mouth and sore throat.
Dry Mouth A feeling of dryness in the mouth, often paired with a dry throat.
Post-Nasal Drip Mucus buildup at the back of the throat, causing irritation, due to aggravation of sinus or nasal issues from CPAP airflow.
Hoarseness or Voice Changes Changes in voice quality, such as hoarseness or raspiness.
Coughing A dry, sometimes persistent cough, especially in the morning.
Morning Sore Throat Pain localized in the throat, particularly noticeable upon waking, potentially lasting for hours after prolonged CPAP use overnight,

 


The Downside of Not Dealing with CPAP Sore Throat

Ignoring a CPAP-related sore throat can lead to several negative consequences, potentially affecting both your health and the effectiveness of your therapy. Here are the downsides of not addressing a sore throat caused by CPAP use:

1. Disrupted Sleep Quality

Persistent throat discomfort can significantly disrupt your sleep. A sore throat may cause you to wake up frequently during the night, reducing the quality of your sleep and worsening symptoms of sleep apnea, such as daytime fatigue and trouble concentrating.

2. Reduced CPAP Compliance

Discomfort from a sore throat might cause you to use your CPAP machine less consistently. Reduced compliance with CPAP therapy diminishes its effectiveness, leaving your sleep apnea untreated. This increases the risk of serious health complications, such as heart disease, high blood pressure, skin irritation, and stroke.

3. Chronic Throat Irritation

Chronic throat irritation from untreated issues like dry air or mask leaks can lead to ongoing inflammation. Over time, this can worsen, leaving your throat more vulnerable to infections and respiratory illnesses, which can further interfere with CPAP therapy.

4. Increased Risk of Respiratory Infections

If the sore throat is caused by dryness or air leaks, the persistent irritation can lead to respiratory infections like sinusitis or bronchitis. These infections can complicate your CPAP therapy and require medical treatment, making it harder to manage your sleep apnea.

5. Lower Oxygen Levels

Failing to address a sore throat can lead to lower oxygen levels during sleep if you reduce or stop using the CPAP. This can put additional strain on your cardiovascular system, leading to long-term health problems such as heart disease or stroke.

Ways To Prevent A Sore Throat From CPAP Machine

CPAP therapy is a highly effective treatment for sleep apnea, but it can sometimes come with side effects, such as a sore throat. However, with a few adjustments and the right accessories, you can minimize or eliminate this discomfort. Here are effective strategies to prevent and stop CPAP sire throat:

1. Ensure Proper Mask Fit

A well-fitting CPAP mask is crucial to prevent air leaks that can allow air to escape, contributing to dry mouth and throat irritation. Make sure your mask fits snugly without being too tight, and adjust straps as needed to create a secure seal.  Use mask liners or cushions for a better seal if needed.

2. Use a heated humidifier

A heated humidifier adds moisture to the air delivered by the CPAP machine keeping your airway hydrated and, preventing dry air from irritating your mouth and throat from drying out. Ensure your humidifier is properly set and, if needed, increase the humidity level.

3. Opt for Heated Tubing

Heated tubing can help maintain a consistent temperature for the air coming from your CPAP machine. This prevents cold air from drying out your throat, making your therapy more comfortable, especially in colder climates or rooms.

4. Adjust Your Pressure Settings

If the pressure setting on your CPAP machine is too high, it can force air through your throat in a way that irritates you.  Use the "ramp" feature to start with low pressure and gradually increase it. Consult your doctor to ensure your pressure settings are optimized for your comfort and therapeutic needs.

Note: Never adjust your pressure settings without the guidance of your healthcare provider.

5. Try a Chin Strap

A chin strap helps keep your mouth closed during sleep, which is especially useful for users who breathe through their mouth while using a nasal CPAP mask or nasal pillow mask. It encourages nasal breathing and prevents dry air from drying out your mouth.

Also, try Mouth tape or sleep strips which can help users who breathe through their mouths by keeping their lips sealed during sleep. This encourages nose breathing and minimizes the symptoms.

6. Try a Different Mask

If you use a nasal or nasal pillow mask and don’t want to use a chinstrap, another option is to try a full face mask instead. A full face mask that covers both your nose and mouth may be more effective. It ensures continuous airflow without leaks, helping to prevent dry throat during CPAP therapy. This mask is cushioned for comfort and comes in various sizes to ensure a good fit and seal.

7. Clean Your Equipment Regularly

Daily Cleaning and sanitizing:

  • Wipe down your mask cushion with CPAP wipes or mild soap and water
  • Empty and rinse the humidifier chamber with distilled water
  • Hang tubing to air dry if any condensation is present

Weekly Cleaning:

  • Deep clean all components (mask, tubing, humidifier chamber) with mild soap and warm water
  • Allow all parts to air dry completely before reassembling

8. Replace CPAP Supplies Regularly

Worn-out masks, tubing, and filters can cause air leaks and lead to dryness and irritation. Regularly replacing your CPAP supplies ensures the equipment functions properly and prevents sore throats caused by faulty components.

  • Change filters as recommended by the manufacturer (typically every 2-4 weeks for disposable filters)
  • Replace mask cushions every 1-3 months
  • Replace the entire mask every 6-12 months
  • Change tubing every 3-6 months
