Effectiveness of nasal dilators in preventing snoring
The hypothesis that the nasal dilator will help to reduce the snoring period of the participants has been proven to be true.
Snoring can interrupt and disturb the sleep of both the snorer and the person sharing the snorer’s bedroom. This causes them to become drowsy, easily irritable and unfocused during the day. Sometimes, the person with the snoring problem will become isolated and may face problems with their roommate or spouse. Simple remedies like using a nasal dilator or changing the sleeping position can help to reduce snoring.
Try to repeat the experiment by observing the number of time the participant tosses and turns during sleep with and without the nasal dilator.
The experiment can also be repeated to compare the effectiveness of external use and internal use nasal dilators.
