Learn how better breathing supports your wellbeing

Try Flow

A Common Problem

Breathing difficulties are so common that many people don't even realise they're experiencing them — or how much better they could feel with improved airflow.

67%

More than two-thirds of people report experiencing difficulty breathing through their nose — even while at rest.

37%

More than one in three adults snores regularly. Snoring is often associated with restricted airflow during sleep.

80%

A reported deviated septum. A deviated septum is common and can contribute to breathing difficulties, nasal congestion, and sleep disturbances.

The Solution

When breathing flows freely through the nose, the entire body functions more efficiently. Better nasal airflow can support focus, recovery, and overall comfort throughout the day and night.

Flow is designed to support natural nasal breathing by gently opening the nasal passages. It stays securely in place and helps maintain more consistent airflow when your body needs it most.

Less Snoring

When air moves more freely through the nose, breathing can become calmer and snoring may be reduced naturally.

Deeper, More Restful Sleep

More consistent breathing throughout the night can support recovery and help you wake up feeling more refreshed.

Easier Breathing

More open nasal passages can help relieve feelings of congestion and pressure around the face and sinuses.

The Science of Breathing

The way we breathe affects nearly every major function in the body — from cognitive and emotional processes to cardiovascular health, metabolism, and sleep.

Breathing is not simply a way to take in oxygen. It plays an important role in many of the body's natural regulatory systems.

Consistent nasal breathing is the body's natural way of breathing. Research suggests that breathing through the nose helps filter, warm, and humidify the air before it reaches the lungs, while also supporting healthy respiratory function more effectively than mouth breathing.

Here are some of the most important things you should know.

Let's Start With the Biggest Issue: Mouth Breathing

Long-term or habitual mouth breathing is surprisingly common. Many adults and children breathe through their mouth during the day or while sleeping, often without even realising it.

Mouth breathing is more than just a habit. Research has linked it to a range of potential issues, including:

  • Poorer sleep quality
  • Increased snoring
  • Reduced airflow during sleep
  • Oral health concerns
  • Lower daytime energy levels
  • Reduced concentration and focus

Many ear, nose and throat (ENT) specialists suggest that mouth breathing is often associated with restricted nasal airflow rather than an increased need for air.

Why Can Mouth Breathing Be a Problem?

Research suggests that mouth breathing may affect several important systems in the body:

Nervous System
Mouth breathing has been associated with changes in the body's stress-response system, which may influence relaxation, recovery, and overall wellbeing.

Exercise Performance
Breathing through the mouth often leads to faster, shallower breathing patterns, which may increase heart rate and reduce breathing efficiency during physical activity.

Respiratory Health
Many people who regularly breathe through their mouth also report allergies, asthma, or other respiratory challenges.

Sleep Quality
Mouth breathing has been linked to snoring, more fragmented sleep, and increased daytime fatigue.

Oral Health
Dry mouth, gum irritation, and a higher risk of dental problems are more commonly reported among mouth breathers.

What About Snoring?

Snoring is one of the most common sleep-related breathing concerns worldwide.

It occurs when airflow becomes partially restricted during sleep, causing soft tissues in the upper airway to vibrate.

Common Causes of Snoring

  • Sleeping on your back
  • Nasal congestion or restricted nasal passages
  • Excess body weight
  • Alcohol consumption
  • Sedative medications

Why Shouldn't Snoring Be Ignored?

Snoring may:

  • Reduce sleep quality
  • Affect daytime energy levels
  • Disturb your partner's sleep
  • Be associated with other sleep-related breathing issues

Nasal Breathing and Sleep

Research suggests that breathing through the nose during sleep may support better sleep quality compared to mouth breathing.

Nasal breathing helps:

  • Support smoother airflow
  • Encourage a more consistent breathing pattern
  • Filter, warm, and humidify incoming air
  • Promote deeper, more restorative sleep

Mouth breathing, on the other hand, is more commonly associated with:

  • Dry mouth
  • Interrupted sleep
  • Morning tiredness

Exercise and Breathing

Many people assume that breathing through the mouth provides more oxygen during exercise. However, research suggests that nasal breathing may improve breathing efficiency, particularly during low- to moderate-intensity activity.

Nasal breathing may help:

  • Regulate breathing rhythm
  • Support more efficient airflow
  • Reduce feelings of early fatigue

Oral Health

Long-term mouth breathing can dry out the mouth and reduce the protective effects of saliva.

Research has linked mouth breathing to:

  • Bad breath
  • Gum irritation
  • Increased risk of cavities and tooth decay

Brain Function and Wellbeing

The way we breathe may also influence cognitive performance and mental wellbeing.

Research suggests that mouth breathing may be associated with:

  • Reduced concentration
  • Headaches
  • Lower daytime alertness

Nasal breathing supports a healthier balance of oxygen and carbon dioxide, which plays an important role in normal brain function.

Summary

Mouth breathing is a common but often overlooked issue that may affect sleep quality, physical performance, oral health, and overall wellbeing.

Nasal breathing is the body's natural way of breathing and is supported by a growing body of scientific research. Supporting healthy nasal airflow may help improve comfort, sleep, recovery, and everyday quality of life.
