Snoring can be a troubling problem for couples. The person who snores often is unaware of it, but their spouse is forced to deal with a noisy saw night after night. Sometimes it is a small saw, and sometimes it sounds like a chainsaw. Once the spouse is awake they will often try to do something to wake up the snorer, such as making loud noises, shaking the bed or even kicking their partner. Pretty soon both people are lying awake, angry with each other. It can be a vicious cycle.
40% of adults snore, and it is more common among men than women (although post-menopausal women snore almost as much as men). It is also more common among those who are overweight.
