Various studies have shown light's numerous effects on the brain. However, a number of recent studies linking human time perception and light raise the possibility of using light to speed up the perception of time. The present study focused on the experimentation and implementation of light into Stockholm’s Slussen station. Evidence of a shortened perception of time when participants are exposed to a visual light stimulus is presented and the results are translated into a metro station light installation design. A better understanding of light and human relationship in the built environment could have important implications for developing strategies in lighting design.
