Light Pollution Linked to Increased Alzheimer's Risk, Study Finds

New research shows a strong association between nighttime light exposure and Alzheimer's disease, particularly in individuals under 65.

The study is the first to link Alzheimer's disease with light pollution, using satellite data and Medicare records across the U.S.
Higher levels of nighttime light exposure were correlated with increased Alzheimer's prevalence, even when other risk factors were considered.
Younger individuals under 65 showed a stronger association between light pollution and Alzheimer's risk compared to older groups.
Disruptions to circadian rhythms and increased inflammation due to artificial light exposure are potential mechanisms behind this link.
Simple measures like using blackout curtains or eye masks at night can help reduce exposure to light pollution.
