环球慢速英语 睡眠问题—打鼾(3)

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.
