Provides for the authority of the department of health to engage in or support research on the health effects of artificial night light

This bill authorizes New York's Department of Health to conduct or fund research on how artificial night light affects human health, including potential links to increased breast cancer risk through melatonin suppression. It directly affects the Department of Health, giving it new authority to pursue this research within existing state and external funding. The key provision adds a specific research mandate to the Public Health Law, requiring the department to study health impacts using available funds from state, public, or private sources. The bill does not create new spending or change existing regulations, only expanding the department's research scope.
