The University of Arizona Sleep and Development Lab studies environmental and behavioral factors affecting sleep and circadian health in children and adolescents, including light exposure, screen media use, and melatonin supplements. We utilize measures of behavior (actigraphy, cognitive tests, sleep and media diaries) and physiology (salivary melatonin, pupillometry) to answer fundamental questions about children’s circadian physiology, as well as to develop and test interventions to improve young children’s sleep and circadian health.

Lauren E. Hartstein, PhD Dr. Hartstein is an Assistant Professor of Psychiatry at the University of Arizona College of Medicine. Dr. Hartstein completed her B.A. in Psychology at Vassar College and her M.S. and Ph.D. in Developmental Science at the University of Massachusetts Amherst. She received training in the non-visual impacts of the lighting environment at the Lighting Enabled Systems & Applications Center at Rensselaer Polytechnic Institute. She then completed a postdoctoral fellowship in child sleep and circadian physiology with Dr. Monique LeBourgeois at the University of Colorado Boulder. Her research interests are focused on questions of how the modern built environment impacts children’s sleep and circadian rhythms across development.

Research Projects
The University of Arizona Sleep and Development Laboratory is looking for child participants for a research study testing two strategies to reduce evening light exposure in order to improve sleep and circadian rhythms.
- We need healthy children ages 5.0 – 6.9 years who have difficulty falling asleep after bedtime for a research study lasting approximately 5 weeks.
- Families will be compensated for participating.
For more information, email sleepdev@arizona.edu or visit the website.
The study has been reviewed and approved by the University of Arizona Institutional Review Board.
