Effects of light on dementia

A study by the Fraunhofer Institute has shown positive results in a community shared with people suffering from dementia. Residents of dementia communities, old people's homes and nursing homes are less likely to see natural daylight. The UMSICHT project is therefore investigating the effects of simulating the color dynamics of artificial lighting based on daylight. An installation can switch between significantly brighter, bluish light during the day and warmer light at night. The light is thereby controlled according to the light composition associated with the time of day or night. This has shown great results in studies of exercise, activity level and sleep-wake behavior. Even on a cloudy day, the lighting level outside is significantly higher than indoors. The aim of research and development is therefore to be able to profitably imitate the natural effects of light inside rooms in the future using special lighting.
