iPAD use close to bedtime could worsen sleep

This article is about a study showing that iPAD use within two hours of bedtime at the brightest setting could suppress melatonin secretion, resulting in difficulty falling asleep. I agree and suspect this is a problem for lots of insomniacs. It's not just ipads, but any electronic device with a screen that you hold close to your face. The article recommends turning down the brightness. You can do that or get a blue light filter to put over the screen. There is software from f.lux that could also reduce blue light emission from your screen.
