Nasal tape, also known as an external nasal dilator strip, is an adhesive device used to enhance breathing by increasing airflow through the nose. This small, bandage-like device is placed across the bridge of the nose to physically lift and open the nasal passages. The primary goal of using nasal tape is to reduce the resistance of air moving through the nostrils, leading to easier and more comfortable nasal breathing. These strips offer a drug-free, non-invasive way to improve breathing, especially during sleep or physical activity.
The Mechanics of Nasal Passage Expansion
Nasal tape is engineered with flexible, spring-like bands embedded within the adhesive strip. When the strip is applied to the nose, the tension of these embedded bands is compressed and held in place by the adhesive backing. The bands then attempt to straighten back to their original flat shape, which creates a gentle, outward pulling force on the skin.
This force is exerted on the sides of the nose, specifically targeting the area just above the flare of the nostril where the lateral nasal valve is located. The nasal valve is the narrowest part of the entire nasal airway, and its flexibility means it can collapse inward during inhalation, especially with rapid or deep breathing. By lifting the flexible cartilage of the nasal walls, the strip pulls the passage open and counteracts this inward collapse. This mechanical action can increase the cross-sectional area of the nasal valve, thereby reducing resistance to airflow.
Common Uses and Real-World Efficacy
The improved airflow makes nasal strips a popular choice for managing a few different conditions, with the most common being mild to moderate snoring. Snoring often occurs when air struggles through narrowed passages, causing the soft tissues to vibrate. By widening the nasal valve, the strips reduce air resistance and velocity, which can lessen the intensity and frequency of snoring for many users.
Nasal tape is also frequently used to combat temporary nasal congestion caused by colds, allergies, or minor structural narrowness. The mechanical lifting action offers immediate, medication-free relief, working whether the obstruction is due to swelling or a naturally narrow passage. Research indicates that these strips can increase nasal airflow by up to 30 percent in some individuals.
A third application is enhancing breathing during exercise. Some studies show the strips can help eliminate ventilator muscle fatigue during intense activity in untrained athletes. However, the strips are most effective for issues originating in the nasal passages and are not a treatment for conditions that arise deeper in the respiratory system, such as severe obstructive sleep apnea. Their overall efficacy depends on whether the root cause of the breathing difficulty is nasal in origin.
Application Techniques and Safety Concerns
Proper application is necessary to ensure the nasal tape functions as intended and stays securely in place. Users must first clean and completely dry the nose and surrounding area. Any oil, sweat, or moisturizer will weaken the adhesive and cause the strip to fail. The strip should be centered horizontally across the bridge of the nose, just above the point where the nostrils begin to flare outward.
After placement, press down firmly for at least ten seconds to secure the adhesive and ensure a tight seal without wrinkles. For removal, peel the strip off slowly and gently to minimize the risk of skin irritation or tearing. Washing the face with warm water beforehand can help loosen the adhesive, making the removal process easier.
While generally safe, common side effects include mild skin irritation, redness, or adhesive residue on the skin. Individuals with sensitive skin or known allergies to adhesives should be cautious and may consider hypoallergenic options. If persistent irritation occurs, try a different brand or consult a healthcare provider.
