Driving for more than two hours a day negatively affects IQ levels, scientists warned. A recent study found that long time behind the wheel could speed up the effects of age on the brain. It might come as bad news for middle-aged drivers. The results could be explained by the fact that the mind is less active on long car journeys.
The big project studied more than half a million British people aged from 37 to 73 over a time of five years. Out of these some 93,000 of them drove more than two or three hours a day. Researchers found that not only did these people have lower brainpower to begin with but their IQ score went down more rapidly over the course of the study than those who did little or no driving.
Kishan Bakrania, a medical expert, said, “We know that regularly driving for more than two or three hours a day is bad for your heart.” And this research suggests it is bad for your brain too, maybe because your mind is less active in those hours.
Previous studies have found that long time of inactivity(不活动) has a bad affect on brainpower. Dr Bakrania’s research shows similar results for those who watched more than two hours of television a day.
