Full Dynamic Circadian Lighting

New research shows increased quality of life for patients with dementia

Today on the dementia ward at the Ceres Center in Horsens, the circadian light is making a difference for the residents and staff. Research findings and opinions of the staff shows that residents have gotten a better sleep rhythm. They show increased mental presence in the daytime, less agitating and restless behavior, they are more at rest in the evening and have improved quality of sleep. The staff experience less headaches during the day and fall asleep easier after evening and night shifts. Implementation of Full Dynamic Circadian Lighting is realized with financial support from Inge and Asker Larsen Foundation for the Support of Charitable Purposes.  



The circadian light and fixed light settings are adapted to the wards overall rhythm, the staffs workflow and the specific needs of care situations. The full dynamic circadian protocol is adapted with input from staff and the associated circadian rythm- and sleep researcher Katharina Wulff from Oxford University, London. Katharina Wulff has simultaneously been leading a research project where she together with staff have measured the effect of Full Dynamic Circadian Lighting, among the 16 severely demented residents in the ward. The innovative lighting solution is implemented on the entire ward, consisting of 16 apartments, hallways, living rooms, orangery, guardroom and offices.

The research project is conducted in cooperation with the staff at Ceres Center Horsens, Oxford University and the Innovation Network DANSK LYS (Danish Light).
