This button in the car can be dangerous if used for a long time

However, a function that many drivers often use can cause problems if left activated for a long time.

It's the internal air traffic button (recirculation) that allows the climate to use the same air inside the cabin instead of getting fresh air from outside.

This function helps to cool the car faster and prevents the introduction of unpleasant aromas or gases from outside.

The problem arises when recycling remains hot for a long time. In the closed cabin, carbon dioxide level (CO₂) can increase, while reducing the supply of fresh air. This can cause fatigue, sleep, concentration reduction, and slower reactions during driving.

Experts recommend that this function be used only for short periods, such as at the start of the journey to cool the car quickly and then allow air entry.

If the driver feels sudden fatigue or drowsiness, he needs to check whether the review has remained active. /Telegraphy/
