A new study offers interesting results regarding cell phones and sleep.  

The Swedish study indicates those who use their cell phone for three hours straight suffer interferences in their sleep patterns. Dr. Wissam Chatila with Temple University's sleep program calls the study interesting but incomplete: 

"They don't offer any explanation for such findings. They just say this is what we found."

But Dr. Chatila says more research into the effect of radio frequency exposure on sleep could be intriguing:

"The finding that there is a sleep disruption or at least a change in the different stages of sleep with this radio frequency exposure, this is what was fascinating but this will need to be confirmed and the implication of such finding also will need to be better documented and further studied."

According to the study, those exposed to cell phone radiation spent less time in deepest stage of sleep than those who were not exposed.
