AN EXPLORATORY STUDY: THE EFFECTS OF LIGHTING ON MOOD IN A CARDIAC INTENSIVE CARE UNIT

摘要

This study was designed to investigate the effects of lighting on the mood of the patients and staff in a cardiac intensive care unit (CICU) and to clarify the relation between lighting parameters (illuminance, colour temperature, light distribution, colour) and subjects' emotions, based on preliminary work on the non-visual effects of artificial lighting ("Healthy lighting and tentative application at Chinese Antarctic Station" and "Innovative application of LED media interface in cardiology operation room based on emotional effect"), which concluded that coloured light was indispensable in influencing emotion and wellbeing, and that light with changeable colour temperature and illumination were effective in releasing mental and physical fatigue. It will provide theoretical support and quantitative guidance for healthy lighting design in CICUs and to improve patient wellbeing as well as minimizing the staff, stress.
