While sleeping the throat muscles relax, the tongue falls backwards, and the throat becomes narrow and 'floppy', and as you breathe, the throat walls begin to vibrate that leads to the characteristic sound of snoring.
Snoring can occur intermittently or nightly and becomes more serious as people age.
Males are generally more at risk, especially those that are overweight, though it is a problem of both genders.
Snoring can cause disruptions to you and your partners sleep, leading to fragmented and un-refreshing sleep that translates into poor daytime functioning.
