Obligate Nasal Breathing
- Definition: Instinct to breathe through the nose rather than the mouth.
- Can refer to cases where breathing through the mouth is possible but not preferred.
- Some define it as the ability to breathe through the nose while swallowing.
- Even in obligate nasal breathers, there is a potential path for air to travel from the mouth to the lungs.
- Believed to be an adaptation useful in prey species.
- Examples: Horses, rabbits, cats, rodents are obligate nasal breathers.

Benefits of Nasal Breathing
- Filters and humidifies air, reducing the risk of respiratory infections.
- Promotes better oxygen uptake and carbon dioxide removal, improving overall respiratory function.
- Helps maintain proper pH balance in the body by regulating nitric oxide levels.
- Activates the diaphragm and promotes deep, efficient breathing.
- Improves sleep quality and reduces snoring.

Effects of Mouth Breathing
- Bypasses the nasal filtration system, increasing the risk of respiratory infections.
- Can lead to dry mouth and throat, causing bad breath and dental problems.
- Disrupts the balance of oxygen and carbon dioxide in the body.
- May contribute to sleep apnea and other sleep disorders.
- Affects facial development and can lead to orthodontic issues.

Nasal Breathing and COVID-19
- Nasal nitric oxide has potential antiviral properties and may help mitigate the severity of COVID-19.
- Nitric oxide can inhibit the replication of respiratory viruses, including coronaviruses.
- Nasal breathing may help reduce the risk of viral transmission compared to mouth breathing.
- Maintaining nasal breathing can support a healthy immune system.
- Improves lung function, crucial for COVID-19 patients.

Nasal Breathing in Yoga, Sports, and Children
- Recommended in yoga practice to promote mindfulness and relaxation.
- Helps regulate breath control and maintain a steady rhythm during physical activities.
- Enhances oxygen uptake and improves endurance in athletes.
- Improves focus, concentration, and overall performance.
- In children, mouth breathing can affect facial growth, speech, swallowing, and lead to sleep disturbances and behavioral issues. Early intervention is important for proper development.
