Researchers Warn Air Pollution Is a Threat to Thinking Skills

(Newswire.net — February 2, 2022) Orlando, FL — The scientific community has been carrying out studies to look into the impacts of air pollution on human health, including the brain. 

One study was carried out by researchers from the University of Edinburgh.

The findings have shown that a great exposure to air pollution at the start of life was linked with negative effects on cognitive skills up to 60 years later. 

In this study, the investigators tested the general intelligence of more than 500 people aged roughly 70 years through a test they had all completed at the age of 11 years. It is also worth mentioning the subjects then repeated similar tests at the ages of 76 and 79 years.

The researchers also utilized a record of where each person had lived throughout their life. It was for the purpose of estimating the level of air pollution they had experienced in their early years. The team also used statistical models in analyzing the link between a person’s exposure to air pollution and their thinking skills in later life.

It is further worth noting they considered lifestyle factors, which include smoking and socio-economic status. 

Findings have shown that air pollution exposure in childhood had a small detectable link with a worse cognitive change between the ages of 11 and 70 years.

“For the first time we have shown the effect that exposure to air pollution very early in life could have on the brain many decades later,” said Dr. Tom Russ.

Russ is Director of the Alzheimer Scotland Dementia Research Centre at the University of Edinburgh.

“This is the first step towards understanding the harmful effects of air pollution on the brain and could help reduce the risk of dementia for future generations,” he added.

More studies are still being carried out to explore the various aspects of brain health, especially in the prevention of dementia.

Protecting brain health is important and there are so many ways to do it. Making dietary and lifestyle improvements is key to shielding the mind from threats.
