MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Chaput: Folklore has associated behaviors of animals and humans, and even werewolves, to moon phases of the lunar cycle. However, the empirical evidence that the moon exerts an influence on behaviors is weak and very limited. In order to verify if the full moon is associated with sleep and physical activity of children (and possibly debunk this myth), we used a 12-country study involving 5,812 participants and providing 33,710 24-hour accelerometer recordings of sleep and activity behaviors. Overall, we observed that sleep duration was 5 minutes (1%) shorter at full moon compared to new moon, while activity behaviors were not significantly associated with the lunar cycle in this global sample of children drawn from all inhabited continents. However, the magnitude of this effect on sleep duration is unlikely to be clinically significant from a public health standpoint and people should stop worrying about the full moon.
