Watching more than 3 hours of television a day doubles memory loss in older people, a new study of more than 3,000 adults suggests. Scientist at University College London used memory and fluency tests on the same group of people 6 years apart. They found that those who watched on average less than 3 hours television a day showed a decline ever round 4 to 5 percent, while those who tended to watch more than 3 hours a day declined by an average of 8 to 10 percent. The research team say they believe the alert but passive nature of television watching maybe creating stress on the mind, which contributes to memory decline.
一項(xiàng)以3000多名成年人為實(shí)驗(yàn)對(duì)象的新研究表明，每天看電視超過3小時(shí)會(huì)使老年人記憶力減退問題加重一倍。倫敦大學(xué)學(xué)院的科學(xué)家對(duì)同一組受試者進(jìn)行了一項(xiàng)時(shí)間間隔長達(dá)6年的記憶力和流利性測(cè)試。他們發(fā)現(xiàn)，那些平均每天看電視時(shí)長不到3小時(shí)的人表現(xiàn)出了4%~5%的記憶力衰退問題，而那些習(xí)慣每天看3小時(shí)以上的人記憶力下降的平均幅度為8%~10%。研究小組表示，他們認(rèn)為看電視警覺但被動(dòng)的本質(zhì)會(huì)對(duì)大腦產(chǎn)生壓力，從而導(dǎo)致記憶力的下降。
Older people who watch more television are also less likely to undertake activities knowing to preserve mental functioning, such as reading or interactive screen base pursuits, such as using the internet or playing video games. The researchers say that television viewing maybe a risk factor for all Alzheimer's disease, but more researches needed to establish a link.
同時(shí)，看電視看得更多的老年人也不太可能去做那些我們大家都知道有助于保持大腦活躍度的活動(dòng)，比如閱讀以及上網(wǎng)或玩電腦游戲等基于屏幕、講究互動(dòng)的活動(dòng)。研究人員表示，所有阿爾茨海默癥（老年癡呆）可能都跟看電視有關(guān)，但要確定兩者之間的聯(lián)系還需更多研究。
While watching television may have educational benefits and relaxation benefits, the researchers advise that adults over the age of 50 should try and ensure that television viewing is balanced with other contrasting activities. If you're concerned that the amount of television you're watching could have a negative impact on your health, you should limit the amount of TV watch each day and undertake some healthy hobbies.
盡管看電視可能具有一定的教育、放松作用，但研究人員建議，50歲以上的成年人應(yīng)該努力確?？措娨暸c其他截然相反的活動(dòng)保持平衡。如果你擔(dān)心你看電視的時(shí)長可能會(huì)對(duì)你的健康產(chǎn)生負(fù)面影響，那建議你限制每天看電視的時(shí)間，從事一些健康的愛好。
