About 95 percent of Americans own a cell phone, and 12 percent rely on their smartphones for everyday internet access, the health department said. In addition, the average age when children get their first phone is now just 10, and a majority of young people keep their phones on or near them most of the day and while they sleep. “Children’s brains develop through the teenage years and may be more affected by cellphone use,” Smith said. “Parents should consider reducing the time their children use cellphones and encourage them to turn the devices off at night.”
Other tips for reducing exposure to radio frequency energy from cellphones: Keeping the phone away from the body, reducing cellphone use when the signal is weak, reducing the use of cellphones to stream audio or video or to download or upload large files, keeping the phone away from the bed at night, removing headsets when not on a call, and avoiding products that claim to block radio frequency energy because they may actually increase your exposure.
