但現在的電視還是會傷害眼睛

Under normal circumstances, humans blink around 18 times per minute,

is seen much more frequently in children who spend more time inside.

常常待在室內的孩子就比較會這樣

Not only are you constantly forced to focus on nearby objects

不僅是因為你必須一直看著近物

as opposed to far-off landscapes and distances.

也因為你沒辦法眺望遠方的景觀

But scientists believe that the sun itself, may actually play a role in healthy eye regulation.

不過科學家相信太陽本身可以幫助眼睛保持健康

And while TV might feel like a nice way to relax your body and brain,

雖然電視可以幫助我們放鬆

that may not always be a good thing.

但它也不見得是好的

Not only is a sedentary lifestyle a major contributor to obesity,

不僅因為長期坐著會產生肥胖困擾

but studies have shown that, people who watch less TV tend to burn more calories.

研究也顯示，看比較少電視的人能消耗更多卡路里

Even if they aren't doing more physical activity.

就算他們坐著不動也一樣

Simply doing more mentally rigorous tasks like reading, playing a board game or

只要簡單做一些腦袋運動，像是讀書、下棋或是

simple household activities requires more energy and burns more calories.

簡單的家事，都可以用掉更多能量、消耗更多卡路里

But perhaps the most significant findings relate directly to your lifespan.

但是最顯著的發現還是跟預期壽命有關

研究不僅發現

TV viewing time and risk for diabetes and heart disease

but as shocking as it might be multiple studies have found a correlation between

但更驚人的是，好幾項研究都發現了

TV viewing time and all causes of death .

One study concluded that every hour spent in front of the TV

有一項研究顯示在電視前每坐一小時，

may cut as much as 22 minutes of your life.

壽命就會減少至多22分鐘

Of course correlation does not equal causation

當然關聯性不代表因果關係

and you can have a healthy relationship with TV if consumed in moderation like anything else.

如果適度地觀看，你跟電視間也可以保有健康的關係

At the root of many of these claims is the physical inactivity associated with prolonged TV watching.

這些調查的根基也是因為坐著看電視代表人體沒有在運動

動得越多當然活得越久
