Can’t Sleep? It Could Be Your iPad

CBC Phily by Denise Mann 31 August 2012

New research shows that all of those nighttime hours spent with your tablet can wreak havoc on your sleep.
The bright light emitted from these tablets can suppress melatonin. That’s a hormone that helps control sleep and wake cycles, called circadian rhythms. 

“If they are bright and they are big and are close to your eyes, they have more potential to disrupt your melatonin than the TV, which is usually farther way,” says researcher Mariana Figueroa. She is an associate professor at Rensselaer Polytechnic Institute in Troy, N.Y.
iPhones and other small gadgets may not affect circadian rhythms. “Smaller devices emit less light,” she says. But even if these devices aren’t zapping the body’s melatonin supply, they may still be disrupting sleep by delaying your bedtime, she says.

Possible solutions include:

* Invest in a filter
* Dim the lights
* Hold the tablet further from your face
* Don't use late in the evening
