LRC Recruiting Participants for New Paid Study: Investigating the Effect of Light at Night

The Lighting Research Center (LRC) is recruiting participants over the age of 18 for a new study that will take place on four consecutive Fridays – August 9, 16, 23 and 30.
The study will be testing the effect of light at night on melatonin levels. Participants will need to attend all four scheduled sessions.  In order to be eligible to participate in the experiment, participants must have bedtimes no later than 11:30 pm and wake up no later than 8:00 am. Participants will be asked to keep this regular schedule all weeks of the study. Participants will be asked to wear an actigraph and keep a sleep log all weeks of the study.
Participants will arrive at the LRC at 11:20 pm each Friday night.  Starting at midnight, participants will sit in front of a light box for 1 hour. Each participant will be asked to sit with their chin in a chin rest for this hour.  Participants will also be asked to collect 3 saliva samples during this time. 
You cannot participate in the experiment if you have major health problems or are taking prescription medication (except for birth control pills) — or will be traveling more than one time zone the week before or during the experiment.

Participants will be paid $70 for each session — a total of $280 for completing all four scheduled sessions. Payment will be processed by Rensselaer after completion of each session. If you are interested in participating in the study, please contact Barbara Plitnick at for more information. Thank you! 

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 conducts research in light and human health, transportation lighting and safety, solid-state lighting, energy efficiency, and plant health. 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. 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.
