Light at night causes circadian disruption, which is a known risk factor for adverse cardiovascular outcomes. However, it is not well understood whether personal light exposure patterns predict an individual's risk of cardiovascular diseases.

In a study of 88,905 people, yet to be peer-reviewed, researchers from the Flinders Health and Medical Research Institute, along with colleagues in the UK and the US, showed that avoiding exposure to night light may lower the risk of cardiovascular diseases.
