Light shift for work shifts: How can biomedical research support retail lighting design

摘要

In the past 150 years, our society has gone through a number of significant changes in lighting configurations. Before the advent of electric light, our ecosystems were regulated solely by the rhythms of sunrise and sunset. These transitions in natural lighting occur gradually over the 24 hours that comprise one day. However, the modern world has changed the way we align ourselves to such patterns. We primarily use electric lighting systems with fixed colour temperatures and illuminances during the daytime and for a large part of the hours of darkness we refer to as night.
