Since I don’t have an iPad yet I still read my ebooks with my iPhone and yes, I do read in bed. So far I’ve not experienced any of the issues mentioned below.
The Director of the UCLA Sleep Disorders Center, Frisca Yan-Go,believes that having the iPad in bed with you may not be such a good idea. He says that curling up with an iPad might not be as restful as one might hope because the electroluminescent glow inhibits the production of melatonin and you might drop it too. Too much light right in front of the eyes prevents the brain from producing the melatonin that a person needs to get a good night’s sleep.
This may not be such good news for electronic books on the iPad, though it’s not all good for e-ink devices like the Kindle. Apparently the limited contrast of e-ink screens can cause eye-strain, but at least those with strained eyes are well rested. E-ink screens don’t offer the same contrast as a high-quality printed book, but fare better when compared to a cheap paperback, so it’s a matter of personal taste – if e-ink hasn’t the contrast for you then go for an iPad, but any problems sleeping and you’re better off with e-ink.
It’s too early to say if the lack of melatonin affects a significant proportion of iPad users, or impacts how people use the device, but if nothing else the issue will be keeping a few Apple executives awake for a while.
In my opinion, I think it’s all about logistics. If you can’t sleep because the iPad is too bright then turn it off! I’m sure we can all figure this one out on our own without anymore studies.
