This everyday factor might be linked to Alzheimer's, says new study¡ªWhat you need to know

Alzheimer's disease, a progressive brain disorder that erases memory and thinking skills, still holds many mysteries, and researchers are working tirelessly to uncover its secrets. While there¡¯s no cure yet, every new study brings us a step closer to understanding this complex condition. A recent study published in Frontiers in Neuroscience reveals a surprising new finding: exposure to bright lights at night might increase the risk of developing Alzheimer's.

New research suggests that exposure to bright lights at night, like streetlights and illuminated signs, may increase the risk of developing Alzheimer¡¯s disease, especially in younger people.

According to Robin Voigt-Zuwala, an associate professor at Rush University Medical Center, there's a strong link between Alzheimer¡¯s prevalence and nightly light pollution, particularly for those under 65, as reported by the New York Post.

Researchers based this on light pollution across the lower 48 states in America, grouping them by nighttime light intensity.

They found that artificial light at night can disrupt the body¡¯s internal clock, affecting sleep and, consequently, cognitive health.

For older adults, light pollution was a stronger risk factor for Alzheimer's than alcohol abuse, chronic kidney disease, depression, or obesity¡ªthough not as impactful as diabetes, high blood pressure, or stroke.

However, for those under 65, light pollution topped the list of risks for Alzheimer's.

To mitigate these risks, the study authors suggest simple solutions like using blackout curtains or wearing an eye mask to block out harmful light at night.
