Nose vs. Mouth Breathing: Impacts on Health and Well-Being

Breathing is a fundamental aspect of life, but how often do we consider the way we breathe? Nose breathing and mouth breathing can have distinct impacts on our overall health and well-being. Understanding the differences is important to optimizing our respiratory function, posture, and even sleep quality.
Nose Breathing: Nose breathing involves inhaling and exhaling through the nasal passages. The nose serves several essential functions in the breathing process.

• Filtration: Tiny hairs (cilia) and mucus in the nasal passages filter out dust, allergens, and other particles, preventing them from entering the lungs (Eccles, 2000).
• Humidification: The nasal passages add moisture to the air, ensuring that it reaches the lungs in an optimal state (Krajnik et al., 2008).
• Nitric Oxide Production: The nasal passages produce nitric oxide, which enhances oxygen absorption in the lungs and has antibacterial properties for the body (Lundberg & Weitzberg, 1999).

Mouth Breathing: Mouth breathing bypasses these essential nasal functions and whilst it can provide a quick way to get more air into the lungs during vigorous exercise or nasal congestion, chronic mouth breathing can lead to health issues.
Some of the health implications mouth breathing contributes to include:

1. Dry Mouth and Throat: Breathing through the mouth can dry out the oral cavity and throat, leading to discomfort, increased susceptibility to infections, and bad breath (Farid & Wilson, 2000).
2. Sleep Disorders: Mouth breathing is often associated with snoring and sleep apnea. These conditions can disrupt sleep quality and lead to chronic fatigue and other health issues (Arens & Marcus, 2004).
3. Postural Problems: Chronic mouth breathing can lead to forward head posture as the body adjusts to keep the airway open. This postural misalignment can result in neck pain, headaches, and other musculoskeletal problems (Mew, 2004).
4. Dental Issues: Increased mouth breathing can cause dry mouth, leading to an acidic oral environment that promotes tooth decay and gum disease (Klein, 1980).

By making small adjustments to our breathing habits, we can create health benefits and improve our overall well-being. Start by becoming more aware of your breathing patterns and take proactive steps to encourage nose breathing.
