Cell phone radiation may be more of a concern than ever before, with a new study revealing that sleep patterns are severely disrupted by cell phone use.

The research, undertaken by the Electromagnetic Academy based at the Massachusetts Institute of Technology, exposed 71 men and women between the ages of 18 and 45 to mobile phone radiation as they prepared to sleep. The initial light phases of sleep in the subjects were affected. In addition, those exposed to mobile phones while they slept appeared to have more headaches as opposed to those not exposed.

The study was funded by the Mobile Manufacturers Forum, which facilitates joint funding of key research projects and cooperation on standards, regulatory issues, and communications concerning health and mobile phones.
