The impact that our built environment will have on us was noted by Sir Winston Churchill when he stated “We shape our buildings; thereafter they shape us”. This profound insight summarizes the research about light and our health that supports the decision to include access to nature in our buildings.
Ulrich at al. proposed in 1991 a psycho—evolutionary theory attributing positive healing effects to nature views through a window. The relationship between bright light, (both natural and artificial), and improved health care outcomes is also well documented (Rashid and Zimring, 2008). It has been demonstrated that increased amounts of sunlight in patients’ rooms improve physiological and psychological health and decrease analgesia use, medication cost, and length of stay (Walch et al. 2005).
The seminal discovery in 2001 of a new receptor cell (ganglion) in the human eye that registers the quality (color) of light and impacts the circadian system initiated research that has continued for a decade (Berson et al. 2002). This article brings together the empirical data of photobiology, syntonic therapy and the various hypothesis of biophilia together to form new perspectives on research for light and its impact on the immune system and our health.
