NIOSH-CDC Awards $2.2 Million for Light and Health Research to the Lighting Research Center

The National Institute for Occupational Safety and Health (NIOSH) and the Centers for Disease Control and Prevention (CDC) have awarded $2.2 million to Rensselaer Professor Mariana Figueiro, Light and Health Program Director at the Lighting Research Center at Rensselaer, to support research that could benefit the more than 7 million Americans working rotating or night shift schedules. The four-year R01 grant from NIOSH-CDC will focus on lighting interventions to reduce circadian disruption in shift workers.

In the U.S. and Europe, 15-20% of all full-time wage and salary workers work alternative shifts. Night shift work, especially prevalent among nurses and other healthcare workers, requires inverting the activity-rest cycle. As a result, shift workers are more likely to experience sleepiness and insomnia, along with decreased productivity, impaired safety, diminished quality of life, and adverse health effects. Light can help night- and rotating-shift workers to stay awake, in part due to suppression of melatonin, but melatonin suppression and the resulting circadian disruption has been linked to increased risk for metabolic syndrome, diabetes, cardiovascular disease, and certain cancers.

Figueiro has demonstrated in laboratory studies that short-wavelength (blue) and long-wavelength (red) light increases alertness and performance at night, although only blue light significantly suppresses melatonin, suggesting that melatonin suppression is not required to promote nighttime alertness and improve performance. The research funded by this most recent R01 grant will field test these laboratory results in a healthcare setting, testing the use of a novel lighting intervention utilizing red light to increase alertness and improve performance in healthcare shift workers without disrupting their natural melatonin production. If shown effective, non-pharmacological treatments to reduce errors in hospital settings and improve quality of life can be applied to help healthcare workers cope with irregular nighttime work schedules without disrupting their circadian rhythms.

Figueiro is also the Principal Investigator for two other multi-year R01 grants from the National Institute on Aging (NIA) aimed at understanding how light can improve sleep in older adults, including those with Alzheimer’s disease and related dementias.


About the Lighting Research Center
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is the world's leading center for lighting research and education. Established in 1988 by the New York State Energy Research and Development Authority (NYSERDA), the LRC has been pioneering research in solid-state lighting, light and health, transportation lighting and safety, and energy efficiency for nearly 30 years. LRC lighting scientists with multidisciplinary expertise in research, technology, design, and human factors, collaborate with a global network of leading manufacturers and government agencies, developing innovative lighting solutions for projects that range from the Boeing 787 Dreamliner to U.S. Navy submarines to hospital neonatal intensive-care units. LRC researchers conduct independent, third-party testing of lighting products in the LRC's state of the art photometric laboratories, the only university lighting laboratories accredited by the National Voluntary Laboratory Accreditation Program (NVLAP Lab Code: 200480-0). In 1990, the LRC became the first university research center to offer graduate degrees in lighting and today, offers a M.S. in lighting and a Ph.D. to educate future leaders in lighting. With 35 full-time faculty and staff, 15 graduate students, and a 30,000 sq. ft. laboratory space, the LRC is the largest university-based lighting research and education organization in the world.

About Rensselaer Polytechnic Institute
Rensselaer Polytechnic Institute, founded in 1824, is America’s first technological research university. The university offers bachelor’s, master’s, and doctoral degrees in engineering; the sciences; information technology and web sciences; architecture; management; and the arts, humanities, and social sciences. Rensselaer faculty advance research in a wide range of fields, with an emphasis on biotechnology, nanotechnology, computational science and engineering, data science, and the media arts and technology. The Institute has an established record of success in the transfer of technology from the laboratory to the marketplace, fulfilling its founding mission of applying science “to the common purposes of life.”
