 Warning: Experts have suggested that every hour of watching TV shortens life expectancy by 22 minutes. |

Every hour spent watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years. The research claims that a sedentary lifestyle is as bad for health as smoking and obesity, because of the dangers posed by inactivity and the greater opportunities it offers for unhealthy eating. The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25. Writing in the British Journal of Sports Medicine, they concluded: ‘TV viewing time may be associated with a loss of life that is comparable to other major chronic disease risk factors such as physical inactivity and obesity.’ The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data. But they said: ‘While we used Australian data, the effects in other industrialised and developing countries are likely to be comparable, given the typically large amounts of time spent watching TV and similarities in disease patterns.’ In the UK, the average amount of time spent watching TV is four hours a day compared with five hours in the United States. Researchers from the Harvard School of Public Health, Boston, said it was ‘biologically plausible’ that prolonged TV viewing results in disease and premature death. Other work suggests that sedentary behaviour is linked to obesity, high levels of bad blood fats and other heart disease risk factors, and more opportunities for grazing on junk foods. Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying prematurely, rises by as much as 20 percent after just two hours a day in front of the box. England’s Chief Medical Officer, Sally Davies, said: ‘Physical activity offers huge benefits and these studies back what we already know – that a sedentary lifestyle carries additional risks. We hope these studies will help more people realise that there are many ways to get exercise.’ Another study shows that exercising for just 15 minutes a day can increase your lifespan by up to three years. It can reduce the risk of early death by 14 percent, with each extra 15 minutes reducing all-cause death rates by 4 percent. (Read by Renee Haines.

一項研究指出，成年人每看一小時電視、DVD或視頻就會減少22分鐘的壽命。每天平均看6小時電視會減壽5年。 該研究稱，久坐的生活方式就跟抽煙和肥胖一樣有害身體健康。因為久坐會對健康造成威脅，也會增加不良飲食的機(jī)率。 學(xué)者們開展此項研究的目的是為了估算看電視對壽命的總體風(fēng)險。他們的研究對象涵蓋了年齡在25歲以上的1.1萬多人。 他們在英國《運(yùn)動醫(yī)學(xué)》雜志上的文章得出結(jié)論說：“看電視的時間長短可能與壽命減少有關(guān)，而且這一因素并不亞于其他導(dǎo)致慢性疾病的主要風(fēng)險因素，例如缺乏運(yùn)動和肥胖?！?/p> 昆士蘭大學(xué)的研究人員采用了來自澳大利亞糖尿病、肥胖和生活方式研究的數(shù)據(jù)，以及澳洲人口和死亡率的數(shù)據(jù)。 他們說：“盡管我們用的是澳大利亞的數(shù)據(jù)，但其影響同樣適用于其他工業(yè)化和發(fā)展中國家，因為這些國家的人們通?？措娨暤臅r間也很多，疾病類型也比較相似?！痹谟?，人們平均每天花4小時的時間看電視，而美國人則每天看5小時電視。 位于波士頓的哈佛公共健康學(xué)院的研究人員說，看電視時間過長會導(dǎo)致疾病和早死，這在生物學(xué)上是講得通的。其他研究也顯示，久坐這一行為方式與肥胖、高血脂等多種心臟病風(fēng)險因素相關(guān)，還會讓人攝入更多垃圾食品。 今年早些時候的一項獨立研究發(fā)現(xiàn)，每天坐在電視機(jī)前2小時，患II型糖尿病、心臟病或過早死的機(jī)率就會上升20%。 英格蘭首席衛(wèi)生官莎莉?戴維斯說：“體力活動會帶來極大的好處，這些研究也支持了我們早已知道的事情，也就是久坐的生活方式是危險的。我們希望這些研究能幫助更多人意識到鍛煉的方式有很多種?！?/p> 另一項研究顯示，每天只需鍛煉15分鐘就可以延長3年壽命，還會使過早死的機(jī)率降低14%。每多運(yùn)動15分鐘就能使各種病因?qū)е碌乃劳雎氏陆?%。 相關(guān)閱讀 調(diào)查：多數(shù)英國人年過四十就“放任自流” （中國日報網(wǎng)英語點津 實習(xí)生沈清 編輯：陳丹妮） |
