I think this is gas-lighting.

Bonfires cause sunburns.

Very confusing article. Who has “artificial light” at night? What does that mean? Street lamps? Can’t people just close their doors and window shades?

[LongWayHome]

They are grasping at straws.

[TonyM]

Whoever came up with this must not be very “bright”!

[GSWarrior]

Not that it means anything, but my mother suffered from Alzheimer’s. She lived in tiny town in the middle of nowhere in western Colorado her entire life.

From the article: Outdoor light at night could be a significant risk factor in Alzheimer’s

Yeah, the Inuits are known for their high rate of Alzheimer's. /sarc

[Patriot777]

So my porch light and my little solar lights can cause Alzheimer’s? And a whole plethora of other maladies?

Light pollution baloney as well.

[Mr Rogers]

Places with “light pollution” are also known as “cities”. Could cities - and how people live in them - be a risk factor for dementia? Given how most cities vote, I’d say “YES!”

[Retain Mike]

"They found that higher nighttime light levels were linked to more cases of Alzheimer’s disease, even when other known risk factors were considered."

They use the words higher and more without any assessment of statistical significance.

My first questions I always ask are who paid for the study and how do they benefit?

Could just be a PhD thesis passed by an unprofessional review committee. I sometimes wonder if universities include anyone capable of rigorous thought.

Adam Smith said, “The average university is a sanctuary in which exploded systems and obsolete prejudices find shelter and protection, after they have been hunted out of every other corner of the world.”

This is cracked!   My whole forty year career in telecommunications was 24/7/365 inside brilliantly lit raised computer floor centers with no outside windows.   For less than two years I was the senior technician at one wire center that had secondary floor windows across one end but it was also brilliantly lit at night.   Believe me, I was fully acclimated to the flood light like saturation over the years.

So now, my senile dementia when it happens, is going to be called Alzheimer’s instead if the product of old age?   Go pound sand overly educated idiots.

[Rockingham]

The effect is real, but with a chain of causation that requires other factors. The abnormal oxidative stress and mitochondrial dysfunction noted in Alzheimer’s Disease and other neurodegenerative disorders can best be explained as the result of a combined Vitamin D and magnesium deficiency. In such a state, more light at night means less recuperative sleep, extra mental activity, and more oxidative stress, compounded by impaired enzyme processes in brain cells due to inadequate magnesium.

What I want to know is what is not a risk for Alzheimers or dementia.

[I want the USA back]

This is what passes as science today.

Reminds me of a similar study from several years back that made people think that a nightlight in a kid’s room led to myopia.

Correlation is not cause.

We have a night light on to light the way for the nighttime trip to the toilet. I wonder if our switch to a LED emits a safe light spectrum to ward off dementia as well as light the way for a safe trip to the toilet.

[TornadoAlley3]

Every pro baseball player should have it.

[marktwain]

Artificial light at night is ubiquitous, especially in cities.

Virtually all the ills described are also more common in cities.

Correlation is not causation.
