19 May Bright Light at Night Linked To Higher Blood Sugar Levels
MedicalResearch.com Interview with:
Kathryn Reid PhD
Professor of Neurology
Northwestern University Feinberg School of Medicine.
MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Reid: There is increasing evidence that light and dark exposure patterns over time impact health outcomes such as body weight and food intake.
This study found that bright light exposure increased insulin resistance compared to dim light exposure in both the morning and the evening.
In the evening, bright light also caused higher peak glucose (blood sugar) levels.
MedicalResearch.com: What should readers take away from your report?
Dr. Reid: Bright light exposure may influence metabolism and highlights that our lighting environment impacts our health.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Dr. Reid: We would like to better understand why light seems to be having this effect, and whether the effects will be maintained with repeated exposures.
MedicalResearch.com: Thank you for your contribution to the MedicalResearch.com community.
