Electronic Devices and Insomnia

I recently read a couple of interesting articles linking the use of iPads, e-readers, and other tech devices to insomnia - or the inability to fall asleep, especially if they are used during the hour before bedtime. Many of these devices have a back-lit display and in the case of the iPad being used as a reader- are held very close to the face. Also, the iPad's blue light in particular sparks alertness. Sleep researchers have proven that light inhibits the release of melatonin or can modify its cycle. This is the hormone that helps settle the body into the sleep mode toward evening. The National Sleep Foundation recently conducted a study called "Sleep and Communications Technology Use". This study found "pervasive use of communications technology in the hour before bed, and also that a significant number of Americans aren't getting the sleep they need and are trying to find ways to cope". This poll is also a "fascinating snapshot of our society's sleep habits" and fairly discouraging since we anticipate a huge transition from print to electronic reading media in the next decade.
