Foregrounding daylight and circadian rhythms in an era of deleterious screen time, “Lighten Up! On Biology and Time” opens at EPFL Pavillions in Lausanne (CH). Featured are works both evocative and therapeutic, “to remind us of the necessity of regular light exposure for a healthy life,” from artists including Kirell Benzi, Olafur Eliasson, and Anna Ridler. Helga Schmid presents a full-on sleep pod (image: Circadian Dreams, 2022), in which visitors laze and soak up LED lighting calibrated to optimize natural body phases.
