Over thousands of years it has been thought that the moon influences human behaviour and the world around us. We reviewed the literature for evidence of a relation of the lunar cycle with the incidence of trauma. We searched Pubmed for studies relating the moon and its phases to trauma. Nine studies were found, of which one suggested an inverse relation of full moon with the incidence of trauma. The lunar cycle might influence trauma incidence, but if any real effect exists, it is certainly small. Moreover such an effect does not require paranormal explanations.
