Light and quality of life

Study in nursing home pc. Katharina shows connections up-causes a higher and dynamically regular light entry with older humans an increase of the well-being and the social activity? Zumtobel presented the results of the study in Vienna. During one period of 15 months Zumtobel accomplished a study in co-operation with the competence centre light and further partners in the dementia department of the nursing home pc. Katharina in Vienna. The investigation had particularly the goal to examine which factors - density of light or spectral composition of the light as well as its dynamic process - to positively affect itself. Main result of the study is: Light in high quantities can improve the circadianen rhythm of older humans, in particular persons in need of care, who do not have a regular entrance to natural daylight. Due to the necessity for a basic redevelopment arose in the home for the elderly pc. To install Katharina in Vienna the possibility on the again furnished dementia station an appropriate lighting system - luminous ceilings, with which different light situations could be produced - and to examine the effects on the inhabitants. In addition the behavior of the inhabitants was observed in particular regarding communication and interaction among themselves and with the care forces, documented and evaluated. Results: � the inhabitants communicate more intensively with the maintenance personnel, this particularly in the afternoon. � with all three light situations an increase of communication was determined. � the inhabitants take part more frequently - particularly with the biologically effective light attitudes - in house-economical activities such as cakes bake, meal preparations and the like. � social activities such as Bastelen, singing etc. are visited increased with light situations with high densities of light. The increased social activities refer to an improvement of the quality of life for the inhabitants of the care station. View: The research is continued. In further homes for the elderly investigations are intended, with which particularly the sleep behavior is more strongly considered. Beyond that the lighting system can be optimized, in order to be able to work even with smaller lighting levels and improved dynamics.
