Light as a Nutrient: Rethinking Smart Homes for the Indoor Species

Lighting

Light is not just for seeing. It is biological information. Modern humans spend around 90% of life indoors, yet most smart homes optimise for brightness, scenes and energy codes - not human biology. We automate convenience while ignoring circadian timing, glare stress and spectral balance. This session reframes light as a nutrient for the indoor species. Drawing on neuroscience and photobiology, it explains how light regulates sleep, alertness, mood and recovery - and how poor design can create chronic visual and neural load. Attendees will learn how to apply circadian-aware scheduling, reduce glare, and integrate biologically informed lighting into residential control systems - turning smart homes into environments that actively support human performance and wellbeing.
