Fall Allergies and Sleep Apnea: How Seasonal Allergies Can Affect CPAP Therapy
Fall brings cooler nights, changing leaves, and, for many people, a fresh round of seasonal allergies. Ragweed pollen, mold spores, dust, and other airborne allergens can trigger congestion, sneezing, and nasal irritation right when you're trying to get comfortable for the night.
If you have sleep apnea and use CPAP therapy, those symptoms can be more than an annoyance. Nasal congestion can make breathing with your CPAP feel more difficult and may affect how comfortable your therapy feels.
The good news? A few adjustments to your CPAP routine can help you navigate fall allergy season more comfortably.
Can Fall Allergies Make Sleep Apnea Worse?
Seasonal allergies don't cause obstructive sleep apnea, but allergy symptoms can make nighttime breathing more difficult.
When allergens irritate the nasal passages, the tissues inside the nose can become swollen and congested. This reduces airflow through the nose and may lead to more mouth breathing while you sleep. Research has found that nasal obstruction associated with allergic rhinitis can increase airway resistance and affect breathing during sleep.
For someone with obstructive sleep apnea, nasal congestion can add another layer of resistance to an airway that's already prone to narrowing or collapsing during sleep.
Allergy symptoms can also disrupt sleep on their own. Sneezing, coughing, congestion, and postnasal drip aren't exactly a recipe for a restful night.
Why Allergies Can Make CPAP Feel Different
If you normally breathe comfortably through your nose while using CPAP, congestion may suddenly make your usual setup feel less comfortable. Nasal symptoms, including congestion and dryness, are also recognized side effects among some people using CPAP therapy.
You might notice:
-
Difficulty breathing through your nose
-
Increased mouth breathing
-
Dry mouth when you wake up
-
Nasal irritation or stuffiness
-
More frequent mask adjustments
-
Trouble falling or staying asleep with your CPAP
That doesn't necessarily mean there's something wrong with your machine. Your needs can simply change when allergy symptoms flare up.
Check Your CPAP Filter
Your CPAP machine pulls in air from the room before delivering it through your mask, which makes the filter an especially important part of your setup during allergy season.
Filters help keep dust and other airborne particles from entering your CPAP device. Depending on your machine, you may have a disposable filter, reusable filter, or both. You can browse Lofta's CPAP filters and hoses to find replacement filters compatible with your machine.
Check your machine manufacturer's recommendations for how often filters should be cleaned or replaced. If your filter looks dirty or discolored, it may be time for a fresh one. The FDA also recommends cleaning or replacing CPAP air filters according to the manufacturer's instructions.
And if you've been putting off routine CPAP maintenance, the start of a new season is an easy reminder to check your CPAP supplies and replacement parts.
Keep Your CPAP Equipment Clean
Your mask, tubing, and humidifier chamber also need regular cleaning.
Following the manufacturer's cleaning instructions can help prevent dust, oils, residue, and other buildup from accumulating on the equipment you use every night. The FDA recommends following the manufacturer's cleaning instructions and notes that most detachable CPAP accessories can generally be cleaned with mild soap and water unless the manufacturer specifies otherwise.
Pay particular attention to the parts that come into direct contact with your face and the water chamber if you use a humidifier. Lofta also carries CPAP cleaning supplies for regular equipment maintenance.
Don't Overlook Your Humidifier
CPAP humidification can be especially helpful when your nose and throat already feel irritated.
A CPAP humidifier adds moisture to the pressurized air you breathe, which may help reduce dryness and irritation associated with therapy. Research has found that heated humidification can reduce nasal symptoms in some CPAP users, although studies have shown mixed results on whether it improves overall CPAP adherence.
If you're waking up with a dry nose, throat, or mouth as the weather changes, take a look at your humidifier settings. Your ideal setting in September may not be the same one that worked during a humid summer. If you need a replacement chamber, heated tubing, or other humidification components, you can browse Lofta's CPAP machine parts and accessories.
Just remember that more humidity isn't always better. Too much moisture can cause condensation, sometimes called "rainout," inside your tubing or mask.
Consider Whether Your Mask Still Works for You
If congestion makes nasal breathing difficult, you may find your usual nasal mask or nasal pillows less comfortable during allergy season.
Some CPAP users who frequently breathe through their mouth prefer a full-face mask, which delivers airflow through both the nose and mouth. Lofta offers a range of full-face and hybrid CPAP masks designed for different sleep and breathing styles.
That doesn't mean everyone with seasonal allergies needs to switch masks. But if congestion is consistently interfering with your therapy, talk with your healthcare provider or sleep specialist about whether another mask style could be worth considering. You can also explore Lofta's CPAP mask selection to compare nasal, full-face, hybrid, and nasal pillow options.
Create a More Allergy-Friendly Sleep Environment
Your CPAP setup is only one part of the equation.
Simple changes in your bedroom may also help reduce your exposure to allergens. Depending on what triggers your symptoms, that could include keeping windows closed when pollen levels are high, washing bedding regularly, showering before bed, or keeping pets out of the bedroom.
If you use an air purifier, make sure its filters are also being replaced according to the manufacturer's recommendations.
