Sneezing and Snoring: Unraveling Their Hidden Connections

Last updated: August 16th, 2023

Let's delve deeper into the indirect relationships between sneezing and snoring and the potential underlying conditions that might link the two.


Allergic reactions occur when the body's immune system responds to a substance (allergen) as if it were a harmful pathogen, like a virus or bacterium.

  1. Sneezing: One of the body's primary defenses against inhaled allergens is sneezing. This is a reflex mechanism designed to expel the allergen from the nasal passages.

  2. Snoring: Allergies can also lead to nasal congestion and inflammation. Swelling within the nasal passages reduces the space for airflow, making it harder to breathe and potentially causing snoring.

Respiratory Infections:

Respiratory infections like the common cold, flu, or sinusitis can lead to inflammation in the airways.

  1. Sneezing: Viral infections can irritate the nasal passages, leading to sneezing as a means to clear out the virus-laden mucus.

  2. Snoring: The mucus buildup and inflammation from infections can narrow the airways. With reduced space for airflow, snoring becomes more likely.

Structural Abnormalities:

Physical abnormalities in the nasal passages or throat can influence both sneezing and snoring.

  1. Deviated Septum: This is when the thin wall between the nasal passages (the septum) is displaced to one side, making one passage smaller than the other. A deviated septum can make breathing difficult and increase the chance of nasal blockages or irritations that cause sneezing.

  2. Nasal Polyps: These are soft, painless, non-cancerous growths on the lining of your nasal passages or sinuses. They can lead to congestion, postnasal drip, and other symptoms. Nasal polyps can cause blockages, making sneezing more frequent and potentially increasing the likelihood of snoring.

Lifestyle Factors:

There are some behaviors and environmental factors that can influence both sneezing and snoring.

  1. Smoking: Tobacco smoke irritates the mucous membranes in the nose and throat. Smokers might sneeze more often as the body tries to clear irritants. Additionally, the irritation and inflammation can contribute to snoring.

  2. Air Quality: Living in an area with poor air quality or a dusty environment can lead to frequent sneezing and increase the chances of snoring. Airborne particles can irritate the nasal passages, leading to inflammation and mucus production.

Can You Wear a Mouthpiece to Sleep for Snoring if You Sneeze and Have Allergies?

Yes, you can wear a mouthpiece (like a Mandibular Advancement Device or Tongue Stabilizing Device) to address snoring, even if you sneeze and have allergies. However, there are some considerations to keep in mind:

  1. Effectiveness: While a mouthpiece can help reduce snoring caused by throat muscle relaxation, it might not directly alleviate snoring caused by nasal congestion due to allergies. If nasal congestion is a primary cause of your snoring, you may also need to address the allergies for best results.

  2. Comfort: If you're experiencing nasal congestion from allergies, breathing through your nose can be challenging. A mouthpiece can further promote mouth breathing, which might be uncomfortable for some people.

  3. Combined Approaches: If allergies contribute to your snoring, a combination of treatments might be most effective. Along with the mouthpiece, consider using nasal sprays, antihistamines, or other allergy medications to reduce nasal congestion.

  4. Mouth Breathing: If allergies cause significant nasal congestion, you might naturally become a mouth breather at night. If you're using a Tongue Stabilizing Device (which often requires a closed mouth to function correctly), this might not be the best choice. A Mandibular Advancement Device, which doesn't require a closed mouth, might be more suitable.

  5. Hygiene: With allergies often comes increased mucus production. Ensure that you clean your mouthpiece regularly to prevent bacterial growth, especially if you find yourself sneezing or having postnasal drip during the night.

  6. Consultation: Before using a mouthpiece or any other anti-snoring device, it's a good idea to consult with a healthcare professional, dentist, or sleep specialist. They can advise you on the best type of device for your situation and ensure that it fits correctly.

While you can wear a mouthpiece for snoring if you sneeze and have allergies, you might need a comprehensive approach to effectively address all aspects of your condition. Addressing the root causes of your allergies and snoring simultaneously will likely offer the most relief.


In summary, while sneezing and snoring are not directly related, they can both be symptoms or side effects of other underlying conditions or environmental factors. Addressing the root causes can often alleviate both symptoms. If you or someone you know has persistent or severe sneezing and snoring, it's essential to consult with a healthcare professional to identify the best course of action.
