Electronic Devices Like the iPad May Cause Sleeping Problems

Why Your iPad Is Keeping You Awake at Night

Picture this: it's the end of the night and you're lying in bed watching a movie on your iPad, or using your laptop to catch up on email. Sound familiar? Well, if you're one of the countless individuals who have trouble sleeping at night, this scenario may be the reason why, reports CNN. If you think about it, it makes sense: falling asleep with the lights on is generally pretty difficult, and the average person's circadian rhythm is set to wake them up a few hours after sunrise. Phyllis Zee, a neuroscience professor at Northwestern University and director of the school's Center for Sleep & Circadian Biology tells CNN:

". . . If you're using [the iPad or a laptop] close to bedtime . . . that light can be sufficiently stimulating to the brain to make it more awake and delay your ability to sleep."

While experts advise turning off all electronics by 10 p.m., they say that using a Kindle or watching TV is preferable over devices like a laptop, smartphone, or iPad because computer screens emit a lot of blue light, which is especially common during the day. If all else fails, there's always going the route of a good old-fashioned book.

Any blue light can keep you awake because it blocks the production of melatonin (a natural sleep hormone) in your brain. If you're obsessed with TV before bed, try wearing "blue blocker" glasses while you watch. They'll seriously distort the colors you see, but should help with your insomnia problems!

noooo! i do have trouble sleeping but i watch most of my tv on my laptop, its just easier! and ever since my nook needed replaced and i was 1/2 way through a book i got in the habit of reading all my books on my computer--i love the back light!!! this is terrible news for me and my night time activities, but not surprising!

i totally agree with this when i was in school i used to sleep with my laptop on and close to my bed and it was crazy distracting and i never slept well i started closing it and putting it far from the bed and i slept much better i love to read a real book before bed...it relaxes me...i just don't think a Kindle would do the same trick
