Scientists have identified light pollution as a significant risk factor for Alzheimer’s disease, particularly among those under 65, according to a new study published in Frontiers.
The research highlights a link between exposure to outdoor artificial light at night and an increase in Alzheimer’s prevalence.
Dr. Robin Voigt-Zuwala from Rush University Medical Center noted that light pollution, a modifiable environmental factor, could play a critical role in Alzheimer’s development.
Global artificial lighting has surged by 49% in the past 25 years, contributing to the growing issue of sky brightness, which has increased annually by up to 10%.
While traditional risk factors like diabetes and high blood pressure are more strongly linked to Alzheimer’s in older adults, for younger individuals, light pollution stands out as a more significant factor.
Researchers suggest that lifestyle changes, such as using blackout curtains, could help mitigate this risk, especially for those living in urban areas.

ngs could serve as a catalyst for more serious efforts to reduce light pollution, much like the global movement to curb plastic pollution.
