Starting from the fundamental findings, Christian Cajochen from the Centre for Chronobiology, Psychiatric Hospital of the University of Basel discusses our current state of knowledge on how short-wavelength, or “blue” light, specifically can impact circadian rhythms and sleep. The webinar focuses on empirical evidence and placing it into the context of interventions in the home and office environment.
