From the TEDx video description:
Did you ever suspected that on moonlit nights it is more difficult to consolidate your sleep? Horacio de la Iglesia shares stories and research studies from his lab that show that human sleep starts later and is shorter on specific nights of the lunar cycle. Horacio de la Iglesia finished his undergraduate studies in Biology at the University of Buenos Aires, Argentina. He got his PhD in Neuroscience and Behavior at the University of Massachusetts, Amherst, where he studied the neuroanatomical interactions between the master circadian clock of mammals and the brain centers that control reproduction. He then continued his research on the neural control of circadian rhythms as a Post-doctoral Fellow and as an Instructor at the University of Massachusetts Medical School. He was also an Instructor at Harvard University. Dr. de la Iglesia joined the University of Washington Department of Biology in 2003, where he teaches and continues his research on biological rhythms and sleep. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
