Effectiveness of nasal dilators in preventing snoringFeatured science projectScience project video


This science fair project was done to find out the effectiveness of using a nasal dilator in stopping the snoring of the participants. The experiment was conducted by video recording the participants sleeping with and without nasal dilators.


The nasal dilator will help to reduce the snoring period of the participants.

Snoring and nasal dilators

Snoring occurs in most adults when the nasal passageway gets obstructed during sleep. The flow of the air we breathe while sleeping will cause vibrations along the respiratory wall and its structures, resulting in the snoring sound. The loudness of the snoring can range from very mild to very loud, and can cause a lot of discomfort and unpleasantness for others sleeping in the same room.

Snoring occurs in almost 30% of adults but this figure will increase to over 50% in people aged over 60. This shows that people will tend to snore more as they grow older. Snoring also causes sleep deprivation for the person who snores and others around them. This causes them to become drowsy and irritable, and lack focus during daytime. Snoring has also been associated with a higher risk of heart attack.

The most common cure for snoring is using a nasal dilator. This is a device that is used to open the nasal passages in the nose so that the breathing can be done more easily and with less resistance. Nasal dilators are available for both external and internal use. External nasal dilators are more common and are mounted over the bridge of the nose. Nasal dilators are also used to relieve nose congestion and improve exercise performance.
