Season 3 – Episode 2: City lights, country nights – Circadian rhythms in urban and rural life

How does life in cities versus rural areas shape our circadian
rhythms? How does access to electricity — or the lack of it —
impact sleep timing? And what happens to our circadian rhythms
when we move from an urban setting to camping outside?


Our guest Luísa Klaus Pilz (Charité -
Universitätsmedizin Berlin) comments on field studies
carried out when she was a PhD student and postdoc at the Federal
University of Rio Grande do Sul (Laboratório de Cronobiologia e
Sono - HCPA/UFRGS).
