Spectral Lighting and Metabolism

The goal of this exploratory n-of-1-study is to compare markers of metabolism in infants in a Level IV Neonatal Intensive Care Unit (NICU) between two lighting environments. Investigators are seeking to learn whether supplementing the lighting environment of infants in the NICU with blue and violet wavelengths of light will allow more efficient utilization of the nutrition provided to participants by influencing hormones involved in regulation of growth and development as compared to a conventional lighting environment. Pre-clinical studies suggest that violet and blue wavelengths of light are involved in molecular pathways that help regulate metabolic activity.
