It has the power to move people out of their bedrooms and onto the living room couch -- or in some cases even out the door. The authors of a Mayo Clinic study on snoring found that the nightime noise can lead to divorce. It rarely bothers the snorer--it most often bothers their bedpartner. In one of the first studies of it's kind the Mayo Clinic researchers looked into how a snoring spouse effects the sleep of his or her partner. Dr. John Shepard is the medical director of the Mayo Clininc Sleep Disorders Center--and senior author of the study. He says the study looked at ten married couples where the husband was the snorer. He says he found that the wives were semi-awakened 23 times a night due to their snoring spouse, so they were motivated to enroll in the study.
