Light and Health Research Center

Light and Health Research Center All living things depend upon light for survival. The Light and Health Research Center is a growing nonprofit research group of 11 employees currently.

The Mount Sinai Light and Health Research Center was created in 2021 to apply the science of light toward improving health outcomes. We are studying how robust patterns of light and dark improve sleep for people from many walks of life, from submariners to premature infants to senior citizens and to all who work in offices, schools, and factories. We are developing lighting schemes to improve the

lives of those living with conditions like Alzheimer’s disease and depression, and those who are undergoing cancer treatment or recovering from traumatic brain injury. We are also exploring the science and application of ultraviolet light to improve vitamin D production in populations who do not get enough sunlight, to control agricultural plant pathogens, and to serve as a germicidal disinfection strategy in the built environment. We are also developing new lighting technologies for safer transportation, from less glaring and more effective lighting for emergency vehicles to airport ground lighting that is better visible to pilots. As Earth’s citizens, we are compelled to focus on lighting applications that are both effective and sustainable. This means developing new metrics for characterizing and quantifying light for a healthy planet, as well as developing design guidelines to assist those who are charged with implementing this research in real spaces. We very much hope you are intrigued with our new center and want to be part of its evolution and impact.

Mark Rea and David Pedler's recent paper argues that greater consideration of user needs when interacting with lighting controls will contribute to reduced lighting energy consumption and support more productive building occupants.

Lighting controls are essential for the operation of all buildings and the well-being of the people who work, live and play in them. The current designs and app...

This randomized trial demonstrated the feasibility of a home-based lighting intervention technology for individuals with mild cognitive impairment ( ). The authors characterize promising effects on both memory and sleep. This work was supported by the National Institute on Aging (5R01AG062288, 5R01AG034157).

Mariana Figueiro recently spoke on the Webby-award nominated podcast Big Picture Science on the theme, Skeptic Check: Blue Light Special.

Many of us know the feeling: we intend to go to bed but pull out our phones for one last scroll. Setting them aside hours later, we’re wide awake, unable to fall asleep. For years, scientists have singled out blue light emitted from our devices as the key culprit behind our post-scrolling insomnia...
