Light affects how we sleep, feel, and perform – yet public awareness of its impact remains limited. The Light for Public Health  initiative aims to make evidence-based knowledge on light and health both accessible and actionable, thus turning scientific insight into public benefit. “Light isn’t just for vision – it is a key signal for human biology,” says Manuel Spitschan, research group leader at the Max Planck Institute for Biological Cybernetics and professor at the Techni

With insights from IALD, WELL, DLA, and leading researchers, this webinar explores daylight-like conditions indoors and their impact on health, design, and circadian well-being. With an increasing evidence base that properties of daylight can positively affect people’s health and well-being, time has come to address the challenge of daylight-like conditions indoors. At present, many people spend time in spaces lit with electric lighting – at work places and in classrooms. How

The CPD covers Designing Lighting to Promote Better Sleep. It involves an in-depth look at what sleep is, what circadian rhythms are and light’s entrainment of them, the effect of circadian disruption on sleep and the knock-on negative effects of sleep deprivation for general health. Connected with above, shortcomings of many indoor lit environments are discussed, followed by a look at lighting recommendations which can go a long way toward solving these shortcomings. The pre

Together with the  Society for Light, Rhythms, and Circadian  Health (SLRCH) , the  Daylight Academy (DLA) , the  International Association of Lighting Designers  (IALD) and  Luger Research (LR) , we are organising and presenting the ‘deLIGHTed Talks’ lecture series. The lectures are free to attend.
