Molecular mechanisms of artificial light at night affecting circadian rhythm disturbance
How artificial light at night may disrupt the body’s internal clock at the molecular level

Abstract
More than 80% of the global population is exposed to artificial light at night (ALAN) pollution.
- Artificially lit outdoor areas are increasing by 2.2% each year.
- The prevalence of night shift work and smart device usage enhances the impact of ALAN.
- ALAN may disrupt biological clocks, leading to disturbances in circadian rhythms.
- Circadian rhythm abnormalities associated with ALAN could affect sleep disorders and various health issues.
- Potential health impacts of ALAN include endocrine diseases, cardiovascular disease, cancer, immune impairment, depression, anxiety, and cognitive impairments.
