Last updated: February 2nd, 2024

Imagine waking up every morning feeling exhausted and unrested, only to learn that your post nasal drip snoring is the culprit. What if we told you that there is a hidden connection between your snoring and post nasal drip? Uncovering this truth might just be the solution that brings you the peaceful, restful sleep you’ve been craving.


Key Takeaways

  • Post Nasal Drip is a condition caused by allergies, sinus infections or colds which can lead to snoring.

  • Various treatments and lifestyle changes may help reduce post nasal drip and snoring.

  • Chronic snoring should be addressed promptly as it can lead to serious health issues. Seek medical advice for proper diagnosis and treatment.

Understanding Post Nasal Drip

Post Nasal Drip is a condition where excess mucus accumulates in the back of the throat, often caused by allergies, sinus infections, or common colds. Our nasal passages are designed to keep the air we breathe clean and moist, but sometimes they produce too much mucus, leading to chronic nasal congestion and other issues.

Allergic Rhinitis

Allergic Rhinitis, commonly known as hay fever, is a condition characterized by persistent nasal congestion resulting from inflammation and congestion. It can disrupt smooth nasal breathing and contribute to post nasal drip snoring. Allergens like house dust mites and pets may be responsible for chronic rhinitis, causing inflammation and congestion in the nasal passages.

Various treatments are available for Allergic Rhinitis, such as over-the-counter oral decongestants, sodium cromoglicate nasal spray, and immunotherapy as approved by medical professionals. These treatments can help alleviate sinus related snoring.

However, being aware of the potential side effects of over-the-counter oral decongestants, such as insomnia, irritability, nervousness, heart palpitations, and elevated blood pressure is necessary. Steroid nasal spray serves as an alternative treatment for post nasal drip and snoring.

Sinus Infections

Sinuses are air-filled cavities located in the frontal region of the skull, and a stuffy nose can be a result of sinus congestion or post nasal drip. Healthy sinuses contain only air, and maintaining healthy sinuses can help alleviate sinus-related snoring.

Sinus infections, such as chronic sinusitis, can lead to post nasal drip and snoring, as they cause inflammation and blockage in the nasal passages. A deviated septum, blocked, clogged, or misshapen sinus cavities may contribute to snoring, and compromised nasal breathing can result in nasal snoring and mouth breathing, both of which can contribute to snoring.

To prevent snoring caused by sinuses, you can consider the following options:

  • Consult a doctor for proper diagnosis and treatment.

  • Explore home remedies such as nasal irrigation, steam inhalation, and using a humidifier.

  • Consider more permanent solutions like Continuous Positive Airway Pressure (CPAP) therapy, oral appliances, or balloon sinuplasty.

Common Colds

Post nasal drip can be triggered by common colds, and both conditions may present similar symptoms, including congestion, coughing, and sore throat. A common cold typically lasts for 7-10 days and can lead to nasal congestion and swelling of the throat, which can worsen snoring.

Over-the-counter cold medications like antihistamines, decongestants, and nasal sprays can potentially aid in improving post nasal drip and ensuing snoring. These medications can help reduce inflammation in the sinuses, reduce mucus production, and alleviate nasal congestion, which can consequently alleviate post nasal drip and reduce snoring.

The Link Between Post Nasal Drip and Snoring


Post nasal drip has been associated with an increased risk of snoring. The consequences of post nasal drip that may lead to snoring include nasal congestion, mouth breathing, and an increased risk of obstructive sleep apnea.

Snoring can be a sign of underlying medical conditions, such as obstructive sleep apnea and certain anatomical variations of the airways.

Various strategies can be employed to reduce post nasal drip snoring, including:

  • Medication

  • Lifestyle modifications

  • Alterations to sleeping position

  • Nasal strips

  • Humidifiers

  • Saline nasal rinses

The key is to identify the root cause of the snoring and address it accordingly.

Nasal Congestion

Nasal congestion resulting from post nasal drip can cause:

  • Inflammation and infection in the sinuses

  • Blocked or clogged airway

  • Excessive relaxation and collapse of airway muscles, resulting in snoring

  • Increased intra pharyngeal pressure, leading to an open mouth posture and obstruction of the airway by the base of the tongue, further contributing to snoring.

Post nasal drip can lead to nasal congestion due to the buildup of mucus in the back of the throat.

Possible causative factors include:

  • Allergies

  • Infections

  • Pregnancy

  • Medications

  • GERD

  • Other conditions

Addressing these factors can help alleviate nasal congestion, reduce snoring, and potentially decrease the risk of developing nasal polyps.

Mouth Breathing


Nasal congestion can lead to mouth breathing due to the obstruction of the nasal passages, which makes it difficult to breathe through the nose. Consequently, individuals tend to switch to breathing through their mouth to obtain an adequate air supply.

Prolonged mouth breathing can have a range of implications on sleep quality, including:

  • Sleep disorders, such as snoring and sleep apnea

  • Fatigue

  • Decreased productivity

  • Decreased quality of restorative sleep

Chronic mouth breathing at night can lead to several issues, including:

  • Dry mouth

  • Sinus congestion

  • Changes in the shape of the mouth

  • Oral health issues, such as tooth decay and gum disease

Addressing the root causes of nasal congestion and finding ways to improve nasal breathing can help promote smoother mouth breathing, alleviate mouth breathing, and reduce snoring.

Obstructive Sleep Apnea

Post nasal drip has been linked to an increased risk of obstructive sleep apnea and obstructive sleep apnoea due to the nasal obstruction and mouth breathing it can cause, which can result in airway blockages during sleep. Obstructive sleep apnea is a condition in which the upper airway becomes obstructed during sleep, resulting in pauses in breathing. It is a serious medical condition that can have potentially serious complications.

Potential indicators that post nasal drip snoring may be linked to sleep apnea include:

  • Loud snoring

  • Choking or gasping for breath during the night

  • Nasal congestion

  • Runny nose

  • Postnasal drip

If you suspect that you may have sleep apnea, it is important to consult a doctor for proper diagnosis and treatment.

Strategies for Alleviating Post Nasal Drip Snoring

There are several strategies for alleviating post nasal drip snoring, including:

  • Medication: Decongestants and nasal steroids can be effective in treating post nasal drip snoring, as they help reduce congestion and sinus pressure, thus opening the nasal airway and promoting natural sinus drainage.

  • Lifestyle changes: Avoiding triggers such as allergens, smoking, and alcohol can help reduce post nasal drip and snoring.

  • Sleeping position adjustments: Elevating the head of the bed or using extra pillows can help prevent mucus from pooling in the throat and causing snoring.

Lifestyle modifications, such as avoiding allergens, staying hydrated, and maintaining a healthy weight, can also be beneficial in reducing post nasal drip snoring. Adjusting sleeping positions, such as sleeping on your side or elevating your head, can help reduce snoring caused by post nasal drip.


Typically, the following treatments are prescribed for post nasal drip and snoring:

  • Nasal steroid sprays

  • Antihistamines

  • Decongestants

  • Cortisone steroid nasal sprays

  • Nasal resistance valves

Decongestants act by decreasing inflammation in the nasal passages and narrowing the blood vessels in the nasal cavity, leading to a decrease in mucus, congestion, and swelling, thereby providing symptomatic relief.

It is important to be aware of the potential side effects associated with some over-the-counter oral decongestants.

These can include:

  • Insomnia

  • Irritability

  • Nervousness

  • Heart palpitations
