Researchers analyzed excessive light exposure across 48 states, finding that higher nighttime light pollution is linked to increased Alzheimer's prevalence, particularly in those under 65.
Dr. Voigt-Zuwala stated, 'We show that in the US there is a positive association between Alzheimer's disease prevalence and exposure to light at night, particularly in those under the age of 65.'
The team highlighted that nightly light pollution, a modifiable environmental factor, could be an important risk factor for Alzheimer's disease, especially in younger populations.
They suggested that awareness of the association should empower individuals to make simple lifestyle changes, such as using blackout curtains or eye masks to reduce light exposure.
