Long journeys by car can affect the brain
If you are driving, you have to be very focused on traffic. With longer distances (e.g. on the motorway) the concentration often drops without the task seeming to be particularly demanding for our brain. Researchers have now found that people who regularly drive more than two hours in a car have a reduced intelligence.

In their study, scientists from Leicester University in Great Britain found that driving a car regularly could reduce the intelligence of those affected. A worrying message - especially for all people who have to travel long distances by car every day for professional reasons. In an interview with the “Sunday Times”, the researchers commented on the new study results.

Does the intelligence decrease due to long trips in the car?
Do you regularly drive long distances by car? If so, your intelligence could suffer. Experts found that the brain breaks down more quickly in middle-aged and elderly people if they travel long distances on the road every day. So should we avoid driving long distances by car? And how should people react who are professionally forced to drive several hours a day every day?

Mentally stimulating activities can slow down the brain breakdown
The scientists explain that those affected can reduce the negative effects on the brain by minimizing their time driving. Also try to find mentally stimulating activities, such as talking to other people to stop cognitive decline in your brain, the experts advise.

Is the human mind less active when driving a car?
"We already know that regular car rides for more than two to three hours a day are bad for the human heart," Leicester University's Kishan Bakrania told the Sunday Times. The current investigation now suggests that it is also bad for the brain if you often drive long distances. The reason for this could be that the human mind is less active during these hours, Bakrania adds.

Regular longer trips by car lead to cognitive decline
For their study, the scientists examined the lifestyles of more than 500,000 British people aged 37 to 73. These participants were medically monitored for a total of five years. During this time, they participated in various intelligence and memory tests. A so-called cognitive decline can already be measured after a period of five years, because this decline can occur quickly in middle-aged people, the scientists explain. This process is associated with various lifestyle factors, such as smoking and poor nutrition. In the future, regular long journeys by car should also be seen as a risk factor for a cognitive decline, explains Bakrania.

If subjects drove a lot of cars, their intelligence sank faster
The researchers found in their investigation that the 93,000 people who drove by car for more than two or three hours each day had lower intelligence on average. In the following five years, intelligence also dropped faster compared to people who drive little or no car. Driving the car causes stress and fatigue. These effects seem to be related to the cognitive decline, Bakrania explains. (as)
