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?

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.?

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.?

開車兩小時以上會降低智商
英國《獨立報》（The? Independent）介紹了一項最新研究，這個研究主要調查久坐是如何影響人們的智力的。研究人員發現每天開車時間超過2到3小時，不僅會損害心臟功能，可能還會持續降低智力，對大腦認知功能造成傷害。英國萊斯特大學醫學流行病學家巴卡尼亞（Kishan? Bakrania）說，原因可能是久坐期間，腦部活動相對不活躍。
研究人員們調查了50萬名年齡在37到73歲之間的英國人，觀察他們的生活方式，并不斷地做智商與記憶測試。研究發現，有9.3萬人每天開車2到3小時，這些人的智商和記憶測試成績在研究開始時就比較低，之后的下滑速度比開車時數較少的人更快、更明顯。這種現象也出現在一天看3小時以上電視的人身上。
研究人員認為，中年人和老年人認知能力的下滑快速，主要與生活形態有關，比如抽煙、飲食不當，現在要新加上一條——開車時間太長。他們還發現，使用電腦工作或玩游戲能夠提升大腦的功能，因為使用計算機的用戶是在接受“刺激”，這和看電視的人群有所不同。
