Car smoke can change brain connections in just two hours

Australia: Smoke from cars is not only harmful to the whole body, but now it has been found that car smoke has such harmful effects on the brain after just two hours that it weakens the brain connections.

Scientists at the University of British Columbia and the University of Victoria have said that the smoke of a car weakens the connections of brain nerves (neurons). This is called brain connectivity or brain connectivity.

In this regard, scientists included 25 healthy and adult people in a random manner. One group was exposed to car smoke and the other was placed in a clean air environment and were not told what the purpose of the research was.

Brain scans of volunteers who spent time in smoky environments were taken and studied carefully. People who were exposed to smoke were found to have weak brain connections called the Default Mode Network (DMN). These places of the brain are very active when we are lost in our thoughts, such as reviewing ourselves, remembering something, etc.

Scientists are unable to say what is caused by dmn weakness, but some research suggests that this can affect the loss of practical memory and the ability to work itself. Jody Goryalak, a scientist involved in the research, says that vehicular pollution can affect the brain.

However, the good thing is that this change is temporary and the brain connections are strengthened again, but experts have indicated more research on those living in this environment for a long time. These include traffic personnel and roadside workers.
