Abstract in brief

The study investigates the link between light at night (LAN) and mortality risk in Mainland China, finding a significant association especially with natural causes of death.
Using nationwide data from 2015 to 2019, the research analyzed daily LAN levels and their impact on mortality in 579 counties through regression models.
Results indicate that higher exposure to LAN correlates with increased mortality, particularly from neurological conditions, highlighting the need for public health policies to address light pollution.
