Snoring occurs when restricted air movement through the nose and throat causes surrounding soft tissues to vibrate. This issue is often exacerbated in the confined, seated environment of an airplane. The combination of seated sleep, which allows the tongue to shift backward, and extremely dry cabin air creates a difficult scenario even for occasional snorers. Travelers need quick, discreet solutions to rest without disturbing their seatmates on a long flight.
Positional and Environmental Adjustments
Maintaining a specific posture is an effective way to reduce snoring while seated. Sitting upright allows gravity to help keep the tongue and soft palate from collapsing into the back of the throat, a common mechanism of snoring. However, the limited recline of an economy seat can cause the head to tilt awkwardly, potentially narrowing the airway.
The goal is to stabilize the head and neck in a neutral position to keep the airway open. A supportive travel pillow, such as a U-shaped or adjustable variety, prevents the chin from dropping onto the chest and compressing the throat. If you have a window seat, leaning your head against the cabin wall helps maintain this stable, slightly elevated position. Avoiding a slumped posture ensures soft tissue around the neck does not add external pressure to the breathing passages.
The cabin environment presents a challenge because the air is significantly drier than on the ground, often having a relative humidity below 20 percent. This low humidity rapidly dries out the mucous membranes in the nose and throat, leading to irritation and congestion. Dry airways are prone to inflammation and vibration, making snoring more persistent.
Counteracting this dryness involves focusing on nasal breathing rather than mouth breathing, as the nose warms and humidifies incoming air. A simple, travel-sized saline nasal spray can be applied before falling asleep to moisten the nasal passages and reduce congestion. Keeping the airways hydrated helps the soft tissues remain less sticky and less likely to vibrate.
Pre-Flight Consumption Strategies
What a traveler consumes before and during a flight influences the muscle tone of the upper airway. Alcohol is counterproductive to quiet sleep because it acts as a muscle relaxant, reducing the resting tone of the throat muscles. When these muscles relax excessively, the airway is more likely to collapse during sleep, guaranteeing snoring.
Similarly, over-the-counter or prescription sedatives, including certain sleep aids, have the same muscle-relaxing effect on the throat tissues. Travelers concerned about snoring should avoid these substances entirely in the hours leading up to and during the flight. This ensures that the airway muscles retain the necessary tension to stay open.
Hydration is a simple strategy that helps mitigate one of the major environmental factors contributing to in-flight snoring. Dry cabin air exacerbates dehydration, which thickens the mucus in the nasal passages, increasing congestion. Maintaining hydration helps keep the throat and nasal passages moist and the mucus thin, promoting easier breathing.
Heavy or rich meals consumed right before attempting to sleep can be problematic. A very full stomach can contribute to mild acid reflux, which irritates the throat lining. This irritation causes swelling and narrowing of the airway, potentially worsening snoring. Opting for lighter fare before boarding avoids this secondary source of airway inflammation.
Over-the-Counter Travel Aids
Several portable, non-prescription products manage situational snoring during travel. Nasal dilator strips adhere to the bridge of the nose and mechanically pull the nasal passages outward. This action widens the narrowest part of the nostril, increasing airflow for individuals who primarily snore due to nasal congestion.
Travel-sized decongestant sprays or simple saline rinses are useful tools to clear pre-existing congestion. Using a decongestant spray about thirty minutes before boarding reduces inflammation and swelling in the nasal lining caused by allergies or a cold. Non-medicated saline sprays can be used frequently throughout the flight to keep nasal tissues moist in the dry cabin air.
For persistent snorers, oral appliances address the issue at the throat level. These devices, ranging from simple boil-and-bite options to custom-fitted guards, work by holding the tongue forward or advancing the lower jaw slightly. Bringing the tongue and jaw forward prevents soft tissues from collapsing backward and obstructing the airway during sleep.
While many of these devices are effective, a custom-fitted mandibular advancement device is often too bulky or conspicuous for quick use on a plane. For air travel, travelers may prefer the simplicity of a non-invasive aid like a nasal strip or a saline spray as a more immediate and discreet solution. The best choice depends on whether the snoring originates primarily from the nose or the throat.
