In this episode, we talk with Dr. Till Roenneberg, President of the World Federation of Societies for Chronobiology, and former President of the European Society for Rhythms Research. He has initiated and directed several large national and international research networks and received several international research prizes and has been named “Ambassador of Sleep” by the German Sleep Foundation. Till has published more than 200 papers that have been cited more than 21,000 times and has written two books, “Internal Time” and “The Right to Sleep”.

We discuss with Till our biological needs for light and darkness, the causes and consequences of Social Jetlag, Daylight Saving Time, and what key features a building should have to support our circadian rhythm.
