Close-up of a man with internal nasal dilators inserted into his nostrils. This device holds the nasal passages open, maintaining airflow and is sold as a solution to snoring. The effectiveness of the device depends upon the underlying cause of the snoring. When snoring is caused by the tongue obstructing the airway this device will have little to no effect. | |
