The Independent introduces a new study which investigates how sedentary affects people's intelligence. The researchers found that driving more than 2 to 3 hours a day not only impairs heart function, but may also continue to lower intelligence and impair brain cognitive function. Kishan Bakrania, a medical epidemiologist at the University of Leicester in England, said the reason may be that brain activity is relatively inactive during sedentary periods. .
The researchers made a survey among 500，000 Britons aged between 37 and 73, observing their lifestyles and performing tests between IQ and memory ceaselessly. The study found that there are 93 ，000 people who drove 2 - 3 hours a day, and their IQ and memory test scores were lower at the beginning. In addition, the IQ and memory 's pace of declines will increase more rapidly than those with fewer driving hours. It also happens to people who watch TV for more than 3 hours a day. .
The researchers believe that the decline in cognitive ability among the middle-aged and the elderly people is fast, mainly associated with lifestyle changes, such as smoking and improper diet, and now we should add a new one – driving for a long time. They also found that working with computers or playing games improved brain function because users of the computer were "stimulated", which was different from television viewing.
开车两小时以上会降低智商
英国《独立报》（The Independent）介绍了一项最新研究，这个研究主要调查久坐是如何影响人们的智力的。研究人员发现每天开车时间超过2到3小时，不仅会损害心脏功能，可能还会持续降低智力，对大脑认知功能造成伤害。英国莱斯特大学医学流行病学家巴卡尼亚（Kishan Bakrania）说，原因可能是久坐期间，脑部活动相对不活跃。
研究人员们调查了50万名年龄在37到73岁之间的英国人，观察他们的生活方式，并不断地做智商与记忆测试。研究发现，有9.3万人每天开车2到3小时，这些人的智商和记忆测试成绩在研究开始时就比较低，之后的下滑速度比开车时数较少的人更快、更明显。这种现象也出现在一天看3小时以上电视的人身上。
研究人员认为，中年人和老年人认知能力的下滑快速，主要与生活形态有关，比如抽烟、饮食不当，现在要新加上一条——开车时间太长。他们还发现，使用电脑工作或玩游戏能够提升大脑的功能，因为使用计算机的用户是在接受“刺激”，这和看电视的人群有所不同。
