Abstract in brief

Light exposure timing plays a crucial role in regulating mood and brain function, as natural light-dark cycles help synchronize our internal circadian rhythms.
Pervasive artificial light at night disrupts these rhythms, affecting sleep, hormone levels, and cellular processes, and is linked to increased risks of cancers, metabolic issues, and mood disorders.
Disruption of circadian rhythms by nighttime light alters brain regions responsible for emotion regulation through changes in neural activity, neuroplasticity, neurotransmission, and gene expression, impacting mental health.]
