Nostril movement, often referred to as nasal flaring, during breathing is usually a sign that you're working harder to breathe.
What is Nasal Flaring?
Nasal flaring is when the nostrils widen while breathing. While slight nostril movement during exertion might be normal, pronounced and persistent flaring, especially when at rest, is usually indicative of respiratory distress.
Why Does Nasal Flaring Occur?
When you're having difficulty breathing, your body tries to compensate by using accessory muscles to increase airflow. The muscles around your nose contract to widen the nostrils, theoretically allowing more air to enter the nasal passages.
Potential Causes of Nasal Flaring
Nasal flaring is most commonly associated with:
- Respiratory Distress: This can be caused by various conditions, including:
- Asthma exacerbation
- Pneumonia
- Bronchiolitis (common in infants)
- Choking or airway obstruction
- Croup
- Severe allergic reaction (anaphylaxis)
- Increased Work of Breathing: Any condition that makes it harder to breathe can lead to nasal flaring.
When to Seek Medical Attention
Nasal flaring is generally considered a sign that you or someone else needs medical attention. If you observe nasal flaring, especially when accompanied by other symptoms like:
- Rapid breathing
- Chest retractions (the skin between the ribs pulling in during breathing)
- Grunting
- Bluish skin (cyanosis)
- Wheezing
Seek immediate medical assistance. This is especially critical in infants and young children, as their airways are smaller and more easily obstructed.
Normal Nostril Movement
While significant nasal flaring is concerning, it is important to note that slight nostril movement may occur during heavy exercise or exertion. This is generally normal, as your body requires more oxygen during these activities. The key is to differentiate between this normal, exertion-related movement and the more pronounced and persistent flaring that indicates respiratory distress.
