In addition to being the stimulus for vision, there is increasing evidence that light influences biology and behaviour through other mechanisms. Laboratory studies, clinical evidence, and epidemiological studies are elucidating effects on hormone regulation, neurotransmitter function, and revealing behavioural and health effects not previously recognized. For instance, daytime light exposure influences both immediate social behaviours and night-time sleep quality.

The evidence suggests that good health requires a minimum daily dose of light, although we do not yet know what the dose ought to be. The presentation will give an overview of recent research, give an indication of research gaps, and summarize possible implications for practical applications through workplace design, architecture, and individual light hygiene habits.
