Oxford Professor of Circadian Neuroscience, Russell Foster, explains his research which shows how the blue-tinged sky of dusk is a trigger that tells our bodies it’s time to prepare for bed[, a]nd why it would be good for us to go back to rising with the dawn and going to bed at sundown.
Rut Blees Luxemburg finds surprising richness of night-time colours in her photographs, and historian Craig Koslofsky shows how early modern Europeans first colonised the night by introducing street lighting.
And most interstingly of all, Craig Koslofsky of the University of Illinois talks about his research for Evening’s Empire: A History of the Night in Early Modern Europe. If you just want to hear about the book, scroll ahead to about 32:15 in the podcast.
