Common Car Air Settings May Cause Fatigue While Driving

# Common Car Settings Can Lead to 'Uncontrollable Tiredness'

Many drivers may unknowingly cause significant fatigue due to a common car setting. Experts highlight that not turning off the air recirculation feature can lead to drowsiness while driving.

This setting, often misunderstood, recycles air within the car cabin. According to a radio host, “When you've got air conditioning in your car, you've got two buttons... A lot of us were told that it would save energy if you put that on because it recycles the air inside your car, and it cools down quicker - that's true." While this saves energy, it can diminish fresh air flow, leading to tiredness.

Sian warned in an Instagram video, “So dangerous and most of us don't know about it!” This highlights the risks for drivers unaware of the connection between air recirculation and fatigue.

Making sure to switch off the recirculation can help maintain alertness. Drivers are encouraged to be mindful of this setting to stay safe on the road.
