So say scientists in the journal Mayo Clinic Proceedings. They had folks wear motion-tracking devices for seven nights and found that those who slept with their dog in the room maintained 83 percent sleep efficiency (the ratio of time spent asleep to total time in bed)—better than the average adult’s sleep efficiency of 80 percent. (Having the dog on the bed, however, slightly lowered sleep quality.) While this study only included dogs, the authors say having any pet in the room can be relaxing and thus conducive to sleep.
