Home Lighting Implications (08-04-21)

How should homes be lit to increase the likelihood of healthy users? Ticleanu report that “A combination of bright daytime light and night-time darkness is essential for circadian entrainment and maintenance of a regular daily sleep–wake cycle. . . . Find indoor seating positions that receive abundant daylight levels but still allow for visual comfort to be maintained. For example, facing towards windows but at an angle and/or at a distance away from them so that glare does not occur, and visual task details are perceived easily, quickly and comfortably.. . .When using electric lighting, ensure it is brighter and has a cooler white colour appearance from mid-morning until early afternoon, then dim it down and set it to warmer white colour appearance towards the end of the day. . . . [after sunset] Face away from electric light sources as much as possible to reduce light levels at the eyes.”
