Snoring is caused by vibration of the soft palate (the soft part of the roof of the mouth) as the lungs strain to inhale oxygen through obstructed airways. Typically, this occurs when the muscles that keep the airways open become too relaxed or excess tissue accumulates nearby and obstructs air flow. Any condition or substance that promotes muscle relaxation or a build-up of fatty tissue can have this effect. 

打鼾是因为进入肺部的氧气受到气道的阻塞，导致软腭振动（口腔上部较软的部分）从而引起打鼾。通常，是因为保持气道打开的肌肉过于松弛或过多的组织积聚在气体通道附近并阻碍空气流动导致的。所以任何促进肌肉松弛或脂肪组织积聚的因素都可能会导致打呼噜。

One helpful trick is to sew a pocket onto the back of your night clothes and insert a tennis ball. This will make it uncomfortable for you to lie on your back - and prompt you to turn on your side during sleep.
