, at least before I go to sleep. txmusclefan saidDespite the sensationalistic title to the article. there is some validity to the study. No, reading from an iPad at night is not "killing you", and the Huffington Post should be ashamed of themselves for putting it that way, and in the process spending some of the credibility.
It has been well-documented that the human body has diurnal rhythms that are affected by cycles of light and dark (day and night), and that affect sleep. That is why light therapy has been used with some success in overcoming jet lag for those traveling over many time zones.
Exposing oneself to a long period of light just before bedtime--from an iPad or anything else--could well affect one's diurnal rhythms and sleep cycle timing. An iPad up close produces a fairly immersive bright light, much more than normal room lighting at night. In the study they exposed the subjects for FOUR HOURS each evening. That was a bit extreme compared to what one is likely to do in normal, everyday use. That is more like light therapy than normal iPad use. Exposure for an hour or so before bedtime would have much less effect, but may still cause some sleeplessness for some people. Note that I said "some" people--not everyone is affected, nor affected to the same degree.
Bottom line, ignore the sensationalistic title of the article. Instead, take this tidbit of information from it: IF you have trouble sleeping at night, and IF you use an iPad or other illuminated device for awhile at bedtime, try discontinuing its use for awhile and see if the situation improves. If you don't seem to be affected by reading on an iPad in the evenings, then don't worry yourself about it.
One thing is for sure, you're NOT going to die from it!

Thanks for the insight/clarification.

I agree! That post was inspired. I look forward to more posts from this guy. He's been here for a couple of years, why does he post so seldom? We could use more from guys like him.
Art_Deco saidI guess I must be the exception to their rule. I learned early on not to take an iPad into bed with me, but for a different reason.
Not because it KEEPS me from sleeping, but because it PUTS me to sleep. Much like reading a book in bed, or watching TV. And I feared the iPad might fall on the floor and be damaged as I dozed off, or one of us would roll over on it in our sleep. And so no more iPad in bed.
Needless to say, I often have my misgivings about so-called "research" and "studies" these days. Like much published academic work coming out lately, I suspect some people have a desire to make their mark in life through artificial controversy and juvenile contrariness.

I've suspected as much. Some studies are worthless, or even worse than worthless depending on how they affect people.
