Nasal Breathing and Sleep Apnea: What to Know
Share
Did you know that over 26% of Australian adults aged 30-70 experience sleep apnea? Breathing through your nose - not your mouth - can significantly improve sleep quality and manage sleep apnea symptoms.
Key Takeaways:
- Nasal breathing filters, warms, and humidifies air, improving oxygen intake by up to 20%.
- Mouth breathing can worsen sleep apnea, snoring, and even lead to daytime fatigue.
- Switching to nasal breathing helps stabilise airways, reduces snoring, and promotes deeper, more restorative sleep.
- Simple solutions like nasal strips, managing congestion, and lifestyle changes can support nasal breathing.
If youโre looking for better sleep and overall health, focusing on nasal breathing is a great place to start.
The role of the nasal airway in sleep
How Nasal Breathing Affects Sleep Apnea
Nasal breathing plays an important role in managing sleep apnea. Breathing through the nose during sleep works with the bodyโs natural processes to keep airways open and ensure a steady oxygen supply. This can influence how often and how severely sleep apnea episodes occur.
How Nasal Breathing Reduces Sleep Apnea Symptoms
Breathing through the nose creates a smoother and more efficient airflow, which is particularly helpful for those dealing with sleep apnea. Unlike mouth breathing, which often leads to turbulent airflow, nasal breathing helps stabilise the airways and reduces the chance of them collapsing during sleep.
It also helps reduce snoring by keeping the airways clear and preventing the soft tissue in the throat from collapsing. Additionally, nasal breathing allows air to remain in the lungs longer and increases oxygen delivery to the bloodstream by up to 20%. This improved oxygen efficiency means that even during short apnea episodes, oxygen levels remain more stable. A consistent breathing pattern can also help lower the frequency and intensity of these episodes.
Studies highlight the benefits of restoring nasal breathing. Among individuals with nasal airway obstruction and sleep apnea, 98% reported subjective improvement in their nasal breathing. In the same group, snoring decreased or disappeared in 34% of cases, and 78% experienced higher energy levels during the day. For those with mild obstructive sleep apnea, simply switching to nasal breathing can make a noticeable difference.
"By embracing the gentle art of nasal breathing and addressing obstacles such as congestion or allergies, you may experience improved sleep quality and a potential reduction in sleep apnea symptoms. This technique can have a dramatic impact on your restorative sleep and overall health." - San Francisco Center for TMJ and Sleep Apnea
On the flip side, breathing through the mouth during sleep can lead to complications.
Health Risks of Mouth Breathing During Sleep
Mouth breathing during sleep disrupts the benefits provided by nasal breathing. It can worsen sleep apnea by narrowing the airway, creating a vicious cycle where poor airflow makes the condition more severe. Mouth breathing also bypasses the nasal passages, reducing the production of nitric oxide - a compound that helps open airways and supports oxygen exchange. This increases the likelihood of obstructions and further complicates breathing. As a result, individuals who predominantly breathe through their mouths often experience fragmented sleep, daytime fatigue, and reduced cognitive performance. Mouth breathing also contributes to airway collapse and increases nasal resistance.
This issue isnโt limited to adults. Mouth breathing is common in children, affecting 10% to 25% of cases. However, it can continue into adulthood, with around 5% of Australians living with sleep apnea.
"Sleep apnea happens when upper airway muscles relax during sleep and pinch off the airway, which prevents you from getting enough air." - Dr Jonathan Jun, Pulmonary and Sleep Medicine Specialist at the Johns Hopkins Sleep Disorders Center
Dry mouth upon waking is another common symptom, reported by 22.4% to 40.7% of individuals with sleep apnea. This suggests that mouth breathing may play a role in more severe cases of the condition.
Benefits of Nasal Breathing for Sleep and Health
Nasal breathing offers much more than just relief from sleep apnoea symptoms. Breathing through your nose, especially while sleeping, can improve oxygen intake and promote better respiratory and oral health.
Improved Oxygen Levels and Sleep Quality
Breathing through your nose is about 22% more efficient than mouth breathing, as it helps regulate your respiratory rate and volume. This makes it more effective for oxygen delivery, leading to deeper, more restorative sleep . Maintaining optimal oxygen levels (ideally between 95โ100%) is critical, and nasal breathing plays a key role by boosting nitric oxide production. This compound helps dilate blood vessels, ensuring steady oxygen flow. These effects can help reduce breathing irregularities during sleep and ease symptoms of sleep apnoea.
Beyond aiding sleep, these respiratory benefits also contribute to better oral health, as outlined below.
Benefits for Oral and Respiratory Health
Your nose acts as a natural air filter, warming, humidifying, and cleaning the air before it reaches your lungs. Mouth breathing bypasses these defences, which can lead to dry and acidic conditions in the mouth - factors that may increase the risk of cavities, tooth demineralisation, and gum disease. By contrast, nasal breathing keeps the air humidified, supporting a healthier balance in your mouth and throat.
Additionally, nasal breathing encourages deeper, diaphragmatic breaths that enhance lung function and oxygen absorption. It also stimulates saliva production, which helps neutralise acids and wash away harmful bacteria. Proper nasal breathing even supports correct tongue and jaw positioning, reducing airway blockages and lowering the chances of snoring and sleep disruptions.
To help maintain nasal breathing throughout the night, BWLL Nasal Strips provide a drug-free, hypoallergenic solution. These strips keep nasal passages open, reducing snoring and supporting uninterrupted, healthy breathing.

Tips for Nasal Breathing at Night
Improving nasal breathing at night can play a key role in reducing sleep apnoea symptoms and enhancing overall sleep quality. Transitioning to consistent nasal breathing during sleep often involves addressing the causes of mouth breathing. Here are some effective strategies to help keep your nasal passages clear and encourage healthier breathing patterns while you sleep.
Managing Nasal Congestion
Nasal congestion is one of the main culprits behind mouth breathing, which can exacerbate snoring and obstructive sleep apnoea symptoms. To tackle this issue, itโs important to identify and minimise exposure to allergens like pollen, pet dander, dust, and mould, as well as irritants such as smoke and strong cleaning products.
- Elevate your head with a wedge or extra pillows to ease congestion.
- Use a neti pot or saline spray for nasal irrigation to clear out mucus and irritants.
- Try steam therapy by taking a warm shower or inhaling steam from a bowl of hot water. A humidifier in your bedroom can also help by maintaining moisture, but ensure itโs cleaned daily and keep humidity levels below 50%.
- Apply a warm, damp compress over your sinuses to relieve discomfort and loosen mucus.
- Stay hydrated throughout the day. If these methods donโt provide relief, consult your doctor about options like antihistamines, nasal steroids, or decongestants.
Dr Abhinav Singh advises:
"I often recommend looking for the culprit - whether it's pollen, dust, etc. - and investing in a good air purifier."
He also notes:
"Frequent decongestant use may have a stimulating effect, so be careful when choosing one".
Using Nasal Strips for Support
Nasal strips are a straightforward, drug-free option to help keep your nasal passages open. These strips work by gently widening your nostrils, which can reduce snoring and provide temporary relief for issues like a deviated septum. While they donโt treat sleep apnoea, they can complement CPAP therapy by improving airflow.
Dr David Rosen, a Sleep Physician, highlights:
"Before considering a trial of nasal strips, a snorer needs to be screened for obstructive sleep apnea. That doesn't always mean getting a sleep study, you can start with a simple questionnaire and always consult with your healthcare provider. If there is no concern for OSA, then by all means see if those strips get your snoring under control."
BWLL Nasal Strips are a hypoallergenic option thatโs safe for daily use, even during pregnancy. For the best results, clean and dry your nose before applying the strip. Place it across the width of your nose and press firmly to secure it. When removing the strip in the morning, use warm water to prevent skin irritation. Incorporating daily habits alongside nasal strips can further support clear nasal breathing.
Lifestyle Changes for Better Nasal Breathing
Encouraging nasal breathing during sleep often requires making broader lifestyle adjustments:
- Sleep on your side or with your head elevated instead of lying on your back.
- Maintain a healthy weight through balanced nutrition and regular exercise.
- Avoid alcohol and sedatives within four hours of bedtime, as these can relax throat muscles and lead to mouth breathing.
- If allergies are a factor, consider reducing mucus-forming foods like dairy and chocolate, particularly before bed.
- Manage stress with practices like meditation, yoga, or deep breathing exercises, which can help train your body to favour nasal breathing.
- Optimise your sleep environment by using a humidifier to keep the air moist and addressing common allergens in your bedroom.
Nasal Breathing vs Mouth Breathing: Key Differences
This section breaks down the differences between nasal and mouth breathing, showing why nasal breathing plays a crucial role in managing sleep apnoea and supporting overall health.
Nasal breathing brings air through the nose, where it's naturally filtered, warmed, and humidified before reaching the lungs. On the other hand, mouth breathing skips these vital steps, which can lead to various complications over time.
Dr J. Michael King explains that the nasal passages act as a natural air filter, conditioning the air by warming and moistening it - something that doesn't happen when breathing through the mouth. This process not only supports better respiratory health but also contributes to more efficient oxygen intake and improved sleep quality.
Statistics show that over 60% of people rely on mouth breathing, which underscores the importance of encouraging nasal breathing. Breathing through the nose is 22% more efficient and improves oxygenation by 10โ20% compared to mouth breathing. For those with sleep apnoea, nasal breathing can reduce the severity of apnoeas, while mouth breathing tends to worsen symptoms like oxygen desaturation.
Comparison Table: Nasal Breathing vs Mouth Breathing
| Aspect | Nasal Breathing | Mouth Breathing |
|---|---|---|
| Air Conditioning | Filters, warms, and humidifies air before it reaches the lungs | Air bypasses these steps, entering the lungs unfiltered |
| Oxygen Efficiency | 22% more efficient with 10โ20% better oxygen delivery | Less efficient oxygen intake |
| Sleep Apnoea Impact | Reduces apnoea severity and improves oxygen levels | Increases apnoeas and oxygen desaturation |
| Oral Health Effects | Encourages saliva production, helping maintain oral health | Reduces saliva flow, increasing the risk of tooth decay and gum problems |
| Sleep Quality | Promotes deeper, more restorative sleep | Disrupts sleep, often causing snoring and fragmented rest |
| Immune Support | Produces nitric oxide and antibodies, aiding immune defence | Delivers unfiltered air, offering no added immune benefit |
| Airway Stability | Supports proper tongue and jaw alignment | Can lead to airway blockage due to tongue position |
| Long-term Health | Encourages normal facial development in children | May result in abnormal facial growth and dental issues |
Dr Thomaz Fleury Curado highlights the importance of nasal breathing, noting:
"Snoring is common and breathing through the nose is best for healthy sleep."
Mouth breathing isn't just disruptive to sleep - it can also aggravate conditions like asthma and allergies, as unfiltered air enters the respiratory system. For children, around 10% to 25% are estimated to be mouth breathers, which can lead to issues like abnormal facial growth, dental problems, and challenges with swallowing and speech.
The evidence makes it clear: the nose is designed to be the primary pathway for breathing, especially when aiming for quality, restorative sleep.
Conclusion: Better Sleep with Nasal Breathing
Nasal breathing plays a crucial role in managing sleep apnoea and improving the quality of your rest. Unlike mouth breathing, it filters, warms, and humidifies the air, helping optimise oxygen intake. For those struggling with sleep apnoea, this can make a world of difference.
Interestingly, nasal resistance accounts for 50โ60% of total breathing resistance. This is why improving nasal airflow can significantly enhance both your sleep quality and overall health.
The benefits arenโt just theoretical - theyโre backed by research. In a 4-week study involving 91 participants, nasal dilator strips were shown to noticeably reduce insomnia severity and improve sleep quality.
