A study led by researchers at the Brown University School of Public Health found that using tuned LED lighting cut in half the number of sleep disturbances among older residents in long-term care. By installing interior lighting fixtures that change color and intensity over the course of the day and night, sleep disturbances experienced by residents in one California nursing home were improved without involving prescribing sleeping pills.

A new research conducted by the University of Arizona Health Sciences found that people who suffer from migraine may benefit from green light therapy, which was shown to reduce the frequency and intensity of headaches and improve patient quality of life. "This is the first clinical study to evaluate green light exposure as a potential preventive therapy for patients with migraine," said Mohab Ibrahim, an associate professor in the UArizona College of Medicine and lead of the study.

Mariana Figueiro, director of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, continues to enhance the lighting treatment developed for older adults with Alzheimer’s disease. The research team recently announced a US$ 3 million grant renewal from the National Institute on Aging (NIA). Figueiro has demonstrated that providing light exposure of certain amounts and qualities throughout the day can improves sleep patterns, sociability, and agitation, while decreasing symptoms of depression. With the latest grant renewal, Figueiro and her t...

Several studies have indicated that flickering light can help to cure Alzheimer disease. A new study published by researchers at Georgia Institute of Technology and Emory University further identifies how the flickering light works. The researchers found that the exposure to light pulsing at 40 hertz – 40 beats per second – causes brains to release a surge of signaling chemicals that may help fight the disease. The new finding was published in the Journal of Neurosceince on February 5, 2020. In 2016, flickering light was first linked with Alzheimer disease with ...

Cytocompatibility studies of organic light-emitting diodes (OLEDs) have been carried out on cell cultures for the first time at the Fraunhofer FEP to test how well OLEDs are tolerated by cells. The results offer promising prospects for the use of OLEDs in the medical field, such as in light therapy. The findings will be published in a white paper entitled “Preliminary cytocompatibility studies for encapsulated OLEDs” and likewise be presented at the 4th Industry Partners Day of the Fraunhofer FEP in Dresden on Sept. 28, 2016.
