Drivers are being warned in regards to the risks of leaving a seemingly easy setting switched on of their autos for long journeys. Failing to modify it off may result in a feeling of “uncontrollable tiredness” behind the wheel, which can shortly develop into a severe hazard.
Most fashionable automobiles are made with an air recirculation button, which blocks outdoors air from coming into the vehicle whereas conserving the interior air circulating. It can show helpful for cooling down during the summer season months, conserving fuel, and blocking out air pollution and ugly odours when caught in site visitors.
However, as beforehand reported by the Daily Mirror, leaving this setting on for more than 20 minutes can show hazardous, because it drains oxygen ranges and raises carbon dioxide (CO2) ranges, which can result in drowsiness and impair focus. Capital Breakfast and ITV’s This Morning presenter Sian Welby found the dangers first-hand.
The 39-year-old revealed that it was solely whereas casually shopping TikTok that she made the connection between the car button and a drawback she had incessantly had whereas driving. In an Instagram video, Sian stated: “So dangerous and most of us don’t know about it!”
The mum-of-one admitted she repeatedly discovered herself yawning and feeling fatigued on car journeys lasting more than half-hour, significantly on motorways. Describing the feeling as “uncontrollable tiredness”, Sian shortly established that a setting present in most autos was the cause of her drawback, experiences the Mirror.
The radio host stated: “When you’ve got air conditioning in your car, you’ve got two buttons, and there’s one that shows a car with arrows-the recirculation button. 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.”
“However, apparently, it’s not designed to be left on, and it can cause drowsiness. So I thought, right, this could be a load of nonsense, but if I get into my car and that button is on, it might be why I’m getting tired.
“I’m going in my car and, sure enough, that button is on. I turned it off, and I did a three-hour motorway journey the opposite day – did not really feel drained as soon as.”
Drivers tend to notice the advantages of the recirculation button during extreme weather conditions, as the vehicle can rapidly cool or heat the cabin without drawing in outside air. Yet without allowing fresh air into the car, occupants become increasingly exposed to carbon dioxide, and within such a confined space, this is precisely what triggers drowsiness — even following a full night’s sleep.

In an Instagram post, Dr Christabel Akinola suggested drivers to “by no means depart the recirculation button on for more than 20 minutes at a stretch”. She said that regular, fresh air is “important” and cautioned anyone feeling inexplicably sleepy behind the wheel to “pull over” and check whether the vehicle’s air quality could be responsible.
A 2018 examine titled “Carbon dioxide accumulation inside autos: The impact of air flow and driving circumstances” discovered that utilising the recirculation setting is the main cause of elevated CO2 levels in car cabins. While brief commutes generally do not exceed a concerning 2,500 ppm, extended journeys and multiple passengers significantly increase the risk of elevated concentrations.
