A new interdisciplinary document summarizes the conclusions of an international scientific consortium in Ladenburg, composed of 21 leading experts in chronobiology, psychology, and neuroscience. The article not only reinforces the finding that light significantly impacts human health and has numerous critical non-visual effects but also provides clear recommendations for health-promoting lighting applications in interiors and light hygiene.
During the day, light benefits us: Bright daylight, according to scientists, improves mood, focus, and overall vitality. Light can give us a boost almost like morning coffee.
In the evening, light can be harmful: Conversely, exposure to inappropriate artificial light in the evening can shift our internal clock and disrupt sleepâeven a quick glance at your phone before bed.
Why does this matter?
Scientists agreed on most of the 26 declared non-visual effects of light and call for clearer public guidelines. The simple rule is: more light during the day, less in the evening, none at night.
The new consensus delivers a clear messageâif we want better sleep, mood, and health, we should start with light. Choosing full-spectrum lighting in offices and other workspaces during the day, which supports alertness, cognitive performance, and overall well-being, will not only benefit us but also earn praise from scientists!
