[io9]Science proves that staring at a screen all day is bad for you

post #1 of 57

Proving the words of countless mothers across countless nations, new research shows that spending all day staring at computers and TVs actually is bad for kids, giving them heart problems later in life. Scientists say that kids who spend many hours in front of screens have narrower arteries in the back of their eyes, and link this to future heart problems.
The study looked at almost 1,500 Australian children, and the results took into account age, sex, ethnicity, iris color, length of the eyeball, BMI, birth weight and blood pressure. The children averaged 1.9 hours of screen time every day, and 36 minutes of physical activity. Every hour of time in front of a monitor equated to a retinal artery 1.53 microns narrower, and associated with a blood pressure increase of 10 mmHg.

So this means that the arteries in my eyes have collapsed in on themselves, and I am now blind?

There are so many other factors to this then just how much time you view a monitor.

Hold up:
Quote:
Conclusion— These data suggest that physical activity could have a beneficial influence, whereas screen time has a potential adverse influence on retinal microvascular structure. The magnitude of arteriolar narrowing associated with each hour daily of TV viewing is similar to that associated with a 10-mm Hg increase in systolic blood pressure in children.
They only studied TV watching. Also it doesn't say that it causes a 10mm Hg increase in blood pressure, but that the effect to the eye is similar to that. IMO you can't instantly say that computer monitors would have the same effect. Also the sample size is pretty restricted / small. :/

An interesting read, though I believe that they need to do a lot more research before making definitive claims.

Uhh 36 min of "activity" a day.... 2 hours of tv, 8 hours of school (sitting), 8 hours of sleep, 5 hours of unknown time that isn't "active". .... If you are only "active" 36 min a day, it doesn't matter how much you stare at a screen. Your heart will have problems later in life...........

I'm not worried at all. Life's short. I'm not going to spazz out because x might be bad for me.


Better to die at 45 having fun than live to 90 while bored, I say.
