Psychologische Befunde zu Licht und seiner Wirkung auf den Menschen - ein Überblick

Psychological evidence on light and its impact on humans - an overview.

The aim of the present article is to describe the light's effects on humans from a psychological perspective and to give an overview of actual psychological research on the influence of light and illumination. In order to optimize lighting applications, it is necessary to know both the routes of influence via which light affects humans and the impact of light and illumination on user's performance, wellbeing, and behavior. Consequently, we first outline the fundamental effect of light on humans and then summarize psychological evidence on the light's influence on task performance, health and wellbeing, social interactions and consumer behavior. Building on this review, the current state of knowledge and need for further research are summarized.
