@curtonews Two hours! This is the time needed to be exposed to traffic pollution for a decrease in the functional connectivity of the brain to occur. ðŸ§

The research, published in the journal Environmental Health (🇬🇧), shows that just two hours of contact with diesel exhaust causes decrease in brain functional connectivity – a measure of how different areas of the brain interact and communicate with each other. 😖

The study provides the first evidence in humans – from a controlled experiment – ​​of altered brain network connectivity induced by air pollution.
O diesel oil – a petroleum derivative – is the most used fuel in Brazil, for different means of transport (buses, trucks, ships, etc.), in addition to industrial machinery.
How did you arrive at the results?
Researchers briefly exposed 25 healthy adults to diesel pollution at different times in a laboratory environment, and also exposure to filtered (pollution-free) air. Brain activity was measured before and after each exposure using functional magnetic resonance imaging.

How to protect yourself?
According to the study, the changes in the brain were temporary and the participants' connectivity returned to normal after exposure. The effects, however, can be long-lasting where exposure is continuous.
Therefore, scientists suggest simple and easy-to-adopt tips:
- When stuck in traffico, think twice before leaving the windows open;
- Ensure that your car's air conditioning filter is in good working order, always clean; It is
- If you are walking or cycling along a busy street, consider diverting to a less busy route.
