Why do I breathe through my mouth at night?

Nocturnal mouth breathing typically occurs when your nasal passages are blocked due to colds, allergies or anatomical problems. Your body then automatically switches to mouth breathing to get sufficient oxygen during sleep. While this is a natural response, prolonged mouth breathing can cause various health complaints and affect your sleep quality.

What causes mouth breathing during sleep?

The main causes of nocturnal mouth breathing are blocked nasal passages due to colds, allergies or chronic nasal congestion. Your body automatically adapts by switching to mouth breathing when normal nasal breathing is impaired. This is a natural survival response to get sufficient oxygen.

Allergies to dust mites, pollen or pets cause swelling of the nasal mucosa, narrowing the airways. Anatomical factors such as a deviated septum, enlarged adenoids or polyps can also cause chronic nasal congestion.

Your sleeping position also plays a role. Sleeping on your back can cause your tongue to fall backwards, partially blocking the airways. Dry air in the bedroom can dry out and irritate the nasal mucosa, making breathing through the nose difficult.

Why is breathing through your nose at night so important?

Nasal breathing filters, warms and humidifies the inhaled air before it reaches your lungs. Your nose also produces nitric oxide, a substance that improves oxygen uptake and dilates blood vessels for better circulation. This contributes to deeper, more restorative sleep.

The nasal passages contain tiny hairs and mucus that filter dust, bacteria and other harmful particles. This natural filtering protects your airways and lungs from irritation and infections. Nasal breathing also regulates the temperature of inhaled air, so your body needs to use less energy to keep body temperature stable.

Additionally, nasal breathing stimulates saliva production, which helps maintain healthy oral flora and dental health. It ensures a better oxygen-carbon dioxide balance in your blood, which is essential for optimal brain function during sleep.

What health risks does mouth breathing at night carry?

Prolonged nocturnal mouth breathing causes dry mouth, dental problems and sore throat by drying out saliva. Without sufficient saliva, bacteria can multiply more easily, leading to gum inflammation, cavities and bad breath.

Your sleep quality deteriorates because mouth breathing is less efficient than nasal breathing. This can result in restless sleep, snoring and even sleep apnoea. You may wake up more often with a dry throat or headache.

In children, chronic mouth breathing can affect the development of facial structures. It can lead to an elongated face, high palate and dental problems. Concentration problems and behavioural issues can also arise from poor sleep quality.

Adults often experience daytime fatigue, reduced concentration and an increased risk of respiratory infections due to the loss of natural filtering by the nose.

How can you prevent mouth breathing at night?

Improve your sleep environment by keeping humidity between 40 and 60% with a humidifier. Sleep on your side instead of your back to prevent your tongue from blocking the airways. These simple adjustments can already make a big difference.

Rinse your nose with saline solution before bedtime to wash away mucus and irritating substances. This opens the nasal passages and reduces swelling. Use a nasal strip if necessary to keep the nostrils mechanically open.

Practice conscious nasal breathing during the day by calmly breathing in and out through your nose. This helps your body get used to this natural breathing pattern. Treat underlying allergies with antihistamines or by avoiding allergens, such as dust mites, as much as possible.

Seek professional help if mouth breathing persists despite these measures. Chronic nasal congestion may indicate anatomical problems that require medical treatment.

How does chiropractic help with nocturnal mouth breathing?

Chiropractic treatments, specifically cranial facial release (CFR), can improve nasal breathing by optimising skull and facial structures. These techniques help restore the natural position of bones around the nasal passages, promoting breathing through the nose.

CFR treatments focus on gently correcting tensions in the skull and face that can affect the nasal passages. Through these cranial facial release techniques, blockages in the sinuses can be reduced and natural drainage can be restored.

The benefits of CFR treatments for nocturnal mouth breathing include:

• Improvement of nasal breathing through optimisation of nasal passage structures
• Reduction of tension in facial and jaw muscles
• Better drainage of sinuses and less congestion
• Support of natural breathing patterns during sleep
• A holistic approach that addresses underlying causes

At Ruggensteun, we combine these specialised CFR techniques with a comprehensive assessment of your breathing patterns and sleep habits. Our experienced chiropractors can help you identify the causes of nocturnal mouth breathing and develop a personalised treatment plan.
