People swear that weird stuff goes down on a full moon. In fact, even SERIOUS folks like the nerds who work in ERs will tell you that something is off about those nights. And what’s amazing is that science has actually looked at this. And … there is some weird stuff here! From animals to ERs to our circadian rhythms to our menstrual cycles, we’ll find out — is something afoot during a full moon? We talk to Emeritus Prof. of emergency medicine Dr. Wendy Coates and circadian rhythm researchers Prof. Horacio de la Iglesia, Prof. Kristin Teßmar-Raible, and Prof. Charlotte Helfrich-Förster.  Find our transcript here: https://bit.ly/ScienceVsFullMoon  In this episode, we cover: (00:00) What do people think the full moon is doing to us?
