Research Confirms that Light Pollution Can Suppress Melatonin Production in Humans and Animals
Melatonin sets the internal clock. Researchers from IGB in an international team have analyzed data on the impact of light pollution on melatonin formation in humans and vertebrates. They found that even the low light intensities of urban skyglow can suppress melatonin production. Melatonin influences the metabolism and other body functions.

University of Manchester Scientists Suggest Blue Light Not So Disruptive to Sleep as Thought
Contrary to common belief, blue light may not be as disruptive to our sleep patterns as originally thought. According to the team, using dim, cooler, lights in the evening and bright warmer lights in the day may be more beneficial to our health. Twilight is both dimmer and bluer than daylight, they say, and the body clock uses both of those features to determine the appropriate times to be asleep and awake.

Tailored Light Improves Sleep Quality, Depression, Agitation in Older Adults with Alzheimer's Disease
Most people associate Alzheimer's disease with profound memory loss, but it is often the symptoms - sleep disturbances, depression, and agitation - that are a challenge to treat, and can significantly reduce the quality of life for both the affected individual and their family members and caregivers. In a research project funded by the National Institute on Aging (NIA), Dr. Mariana Figueiro, Professor and Director at the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, is investigating whether a tailored lighting intervention can lessen the impact of these symptoms in older adults living with Alzheimer's disease and related dementias (ADRD).
