看電視等於慢性自殺 每天6小時壽命短5年

Every hour spent watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests。

It means that 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。

The academics from Queensland University conducted the study and 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。”

This finding is also comparable to risk factors such as smoking, with other research showing that one cigarette cuts 11 minutes off a lifespan – equivalent to half an hour of watching TV。

Other research suggests that sedentary behavior is linked to obesity, high levels of bad blood fats and other heart disease risk factors, and more opportunities for grazing on junk foods。據英國《每日郵報》16日報道，研究表明，成人每多看一小時電視、光碟或視頻就會使其壽命縮短將近22分鐘。

這意味着，一個人平均每天看6小時電視，他的壽命就會縮短5年。

研究稱，久坐不動的生活方式與吸菸和肥胖一樣都對人體有害。

來自昆士蘭大學的學者們對此進行了研究，並着手分析了看電視給人壽命帶來的綜合風險。該研究共涉及11000多名年齡在25歲以上的人。

《英國運動醫學期刊》刊登了該研究，研究人員總結說：“看電視的時間會縮短人的壽命，這不亞於其他主要慢性疾病的風險係數，如缺乏運動和肥胖症。”

看電視的風險係數亦不小於吸菸，有研究顯示，吸一支菸可將壽命縮短11分鐘，只是看電視的一半。

其他研究也表明，長時間坐着的行爲可導致肥胖、壞血脂指數提高、罹患其他心臟疾病的風險增加，並且還給人提供了更多吃垃圾食品的機會。
