Alcohol and medications such as sleeping tablets can also cause the muscles to excessively relax Poor muscle tone in the tongue and throat - this can occur during stages of deep sleep.There are many factors that make a person more likely to snore. The effect is to reduce the quality and benefits of a good night’s sleep and has the potential to cause high blood pressure and heart rhythm abnormalities. This is when snoring is interrupted by frequent episodes of totally obstructed breathing, semi-wakening, and a resumption of breathing. The most exaggerated and potentially dangerous form of snoring is obstructive sleep apnoea (OSA). Then, as air is inhaled and exhaled during sleep, parts of the mouth and throat like the tongue, soft palate, uvula and tonsils can vibrate, producing distinctive snoring sounds. In some people they relax so much that the airway becomes partially blocked. When we sleep the normally firm muscles in the throat relax. On the way, the air passes the tongue, soft palate (the soft tissue at the back of the roof of the mouth), uvula (which hangs at the back of your throat), and the tonsils. When we breathe, air travels into the mouth and/or nostrils, down the throat, and into the lungs via the windpipe (trachea). Heavy snorers are also at greater risk of developing high blood pressure at a younger age than people who do not snore.
Snoring can be disruptive - both for the snorer and anyone within earshot - which means people may not get the quality, restorative sleep they require, leading to daytime sleepiness. Snoring is more common in men than women and the severity of the snoring tends to worsen with age. Surgery and non-surgical treatments, and lifestyle changes, aim to reduce or remove airway obstructions.Īpproximately 50% of New Zealand adults will snore occasionally and approximately 25% will be habitual snorers. Snoring is the sound made by air passing through narrowed airways, which causes parts of the throat or nose to vibrate.
