The cause of snoring
Snoring is caused by vibration of the soft tissues in your head and neck as you breathe. Some people that snore may suffer from obstructive sleep apnoea (OSA). This is where the airways become partially or totally blocked for about 10 seconds.
A fall in the level of oxygen to the brain causes the sufferer to move into a light state of sleep, or even wake for a short period, in order to restore normal breathing. This can occur throughout the night, resulting in a poor night's sleep and daytime sleepiness. It is also associated with a number of general health problems including high blood pressure.
