Light Pollution Linked to Alzheimer’s Risk: Study

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. The findi ngs could serve as a catalyst for more serious efforts to reduce light pollution, much like the global movement to curb plastic pollution. Source: Oman News Agency
