Melatonin the hormon your brain makes to help you fall asleep is destroyed by light this means natural light and artifical light. Therefore watching a screen makes you less sleepy then just sitting in the dark (duh) but that's the point researchers are making.
I work in the TV buisness and watch screen (10-15) and have morning/evening/night shifts. I find that taking melatonin before I go to bed helps me sleep. Where I had trouble sleeping at first.
The stuff about wifi (electro-magnetic) signals interrupting your sleep cycle is something I do not know but that seems stretched.

I've always called bullshit when people say you shouldn't have a computer, or tv in your room, and/or to avoid using electronic devices on your bed, as it could disrupt your sleeping patterns and cause your brain to associate your bed with wakeful activities.
I use all manner of electronic devices in my room, and often go to sleep with a Documentary or something playing in the background, and I have always found I sleep soundly.
Then again, perhaps I am just weird.

I don't think that it's impossible to sleep well with electronics in the bedroom. But if you don't sleep good maybe you should consider to move them.

Both my parents have sleep apnea and thought they were sleeping fine before they got some sleep testing done. My mom went into three straigh hours of REM sleep (normally about 15 mintes of a 90 minute cycle) when they hooked her onto a CPAP machine for the first time.
I'm not telling you how good or bad you sleep, or how accurate the article is, but self reporting sleep quality is pretty unreliable in a lot of situations.
