Daytime light exposure plays an important role in promoting entrainment of circadian rhythms and improving nighttime sleep. This is particularly important for older individuals, especially those living with conditions like Alzheimer’s disease and depression. However, current lighting standards do not take the non-visual effects of light into consideration. Most of us spend 90% of our daytime hours indoors, where lights can be too dim during the day to activate our biological clock and perhaps be too bright in evenings.

This webinar will discuss what we need to do in the built environment to promote brighter days and darker nights. The presenter will share the latest research in light science and will show examples of applications where a robust 24-hour light and dark scheme in numerous environments improved sleep, mood, and behavior in various older adult populations.
