Mar 16, 2017: Rigshospitalet (Copenhagen University Hospital) and the Aarhus University Hospital is working on a project on Chromaviso’s Circadian Light system to study the effect of such lighting on patients’ mental health, sleep, energy, wellbeing and mood.
The project, an interdisciplinary collaboration between clinicians, researchers and lighting experts, will be completed in 2019. The project aims to improve the lighting conditions and treatment for patients who are hospitalized for depression. The project will give results that will form the guidelines for lighting in psychiatry in the future.
The Aabenraa Psychiatric Hospital revealed that the circadian lighting encouraged a calmer, cosier atmosphere and had improved sleep both for patients and for staff.
Aabenraa installed the Ergonomic Circadian Lighting system in September 2015. The surveys looked into the effects of lighting. The purpose of the circadian lighting is to mimic the day/night pattern of the sun, providing blue light during the day and ambers at night, to maintain a circadian balance.
The survey shows that 77% of the patients were calmer; 65% slept better; 57% reported fewer night-time disturbances and 38% observed a reduction in drug consumption among patients.
The staff also benefitted from the human centric lighting—54% felt more energized, and 47% slept better.
