New Study Finds Humans, Not Dogs, Disrupt Sleep During Co-Sleeping
A new University of Toronto study published in PLOS One indicates that sleeping with dogs does not negatively impact human sleep quality or duration. Using activity trackers on 25 people and 38 dogs in southern Ontario, researchers found that humans are more likely to disturb their dogs' sleep than vice versa. While some participants reported poor sleep when sharing a bed with multiple dogs, objective data showed no significant difference in sleep metrics compared to sleeping apart. The findings suggest that dogs may actually help regulate human sleep schedules by acting as 'zeitgebers,' providing consistent cues for bedtime and routine.
