EPFL and HEAD researchers have set-up an installation to raise awareness around the importance of exposure to natural light for human health and the role of the architecture in urban settings in modulating that light. The exhibition will take part in the Seoul Biennale of Architecture and Urbanism this fall 2021. Natural light plays a crucial role in the regulation of our circadian rhythms, which dictate a variety of biological processes, from sleep/wake cycles, our level of alertness and even hormone production. This happens because of a photoreceptor called melanopsin present in our eyes and which was discovered only around 20 years ago, making it a still relatively novel research topic. Moreover, our exposure to light is highly dependent on the architecture of the buildings and the cities we live in. That is precisely what Circa Diem ("about a day" in Latin) aims to highlight with a structure designed and assembled on the EPFL campus this summer 2021.
