Danish Panelists Use Lighting To Improve Sleep In Patients With Dementia
- Apr 20, 2018 -

    A multidisciplinary team consisting of lighting suppliers and a group of "anthropologists" is exploring the possibility of improving the quality of life.

    A nursing home in Denmark is working with academics, industry, and municipal researchers to determine whether a new circadian rhythm lighting system can improve the health and quality of life of people with dementia in the center.

    This nursing home in Albertslund, Denmark, has installed a lamp that changes the color temperature and brightness throughout the day and follows the pattern of natural daylight. The lighting system comes from Danish supplier Chromaviso. In the morning, it slowly turned on. At noon, the light was the brightest, the bluest, and the coldest. At night, warm light was emitted in the corridors and public areas, and the blue frequency was cut off.

    Many people with dementia have difficulty sleeping, sometimes because of their imbalance in circadian rhythms. The so-called circadian rhythm lighting helps to balance their sleep cycles, thereby improving their health and improving their well-being. In addition, moving from a familiar home environment to a nursing home may make them more uncomfortable.

    Mona Funch, the nursing home manager, said: “A lot of our elderly people have a type of circadian rhythm disorder when they come in. This means that they don’t sleep well and may feel tired during the day, which may affect their quality of life. With the installation of circadian rhythm lighting, we hope to see a significant improvement in the circadian rhythm of our elderly people."

    This project, named Lightel, is not the first one. These include: OSRAM installed dimmable lighting equipment at the St. Augustine Memory Center in Neuss, Germany two years ago; Photonstar in the UK installed a circadian rhythm system in the dementia ward at St. Mary's Hospital in London.

    However, the difference in this project is multidisciplinary. In addition to the lighting suppliers, the research team also has a clinical research center at Hvidovre Hospital and an anthropological light designer at Aalborg University in Copenhagen.

    The entire project includes lighting, control, research and management. Divided into three phases, starting in November, 33 elderly and 35 employees were observed under normal lighting for 8 weeks. Then it was observed under circadian lighting for 8 weeks. Next is another phase of control under day and night lighting.

    Torben Skov Hansen, Chromaviso's innovation manager, said: “We have specially modified circadian rhythm lighting for the dementia area to ensure that day and night lighting improves the well-being of the elderly, the work of employees, and the activities of nursing organizations throughout the day."

    Mona Funch, the nursing home manager, added: “We hope that our seniors will sleep better at night when they sleep, that their attention will be improved, and that they will be more willing to actively participate in daily life.”

    Denmark is a hotbed of circadian rhythm lighting and research.

    Hospitals and nursing environments are suitable for circadian rhythm lighting research. In addition, day and night lighting, also known as people-oriented lighting or healthy lighting, has begun to appear in the office environment.
