Summary:
- The article discusses a study that found a link between light pollution in urban areas and an increased risk of Alzheimer's disease.
- The study suggests that exposure to artificial light at night can disrupt the body's circadian rhythms, leading to changes in the brain that may contribute to the development of Alzheimer's.
- Researchers recommend reducing light pollution in cities and towns, as well as using dimmer, warmer-colored lights at night, to potentially mitigate the risk of Alzheimer's disease.
