Only about 59% of those who snore are aware of this, while the rest do not know about the problem at all. Snoring occurs due to the vibration of the tissues near the airway in the back of the throat.
The first thing to do is determine the cause of snoring, as it is usually due to a blockage in the airflow duct. Use special pillows to prevent your husband from snoring on his back, and encourage him to sleep on his side.
