Voice 1: Scientists have discovered that snoring may be connected to families. They found that children are more likely to snore if their parents also snore. But some sleep experts say that it is a family's body type that make them snore. They say that if a parent has extra body fat, their children usually do also. Extra body fat, and large bodies make snoring worse. The person's airways become smaller. This makes snoring worse. Old age also makes snoring worse. As a person gets older, their airways become less firm. This makes snoring louder.
声音1：科学家发现打鼾可能与家庭有关。他们发现，如果父母打鼾，那孩子也打鼾的可能性更大。但一些睡眠专家表示，令人们打鼾的是其家庭的体型。他们表示，如果父母有多余的脂肪，那他们的孩子通常也会有。多余的脂肪和庞大体型会令打鼾更严重。这会使人们的呼吸道变小。继而令打鼾更严重。年老也会加剧打鼾。随着年龄的增长，人们的呼吸道会变得不再坚固。这会令鼾声更大。
