Here are five things not to do, according to the
California guidelines for cellphone health, “How to Reduce Exposure to Radiofrequency Energy from Cellphones."
1. Don’t hold your phone up to your ear.“Use the speakerphone or a headset instead,” because “wireless (Bluetooth) and wired headsets emit much less RF energy than cellphones.” The guidelines also suggest sending text messages rather than talking on the phone whenever possible.
2. Try not to use your phone if you’re in a fast-moving vehicle.“Your phone puts out more RF energy to maintain connections to avoid dropping calls as it switches connections from one cell tower to the next unless it is in airplane mode,” the guidelines state.
3. Avoid using your phone when you have one or two service bars showing.“Cellphones put out more RF energy to connect with cell towers when the signal is weak,” the guide notes.
4. Don’t carry your phone in your pocket, bra or holster close to your body.The guidelines suggest you carry it in a backpack, briefcase, purse or elsewhere, so that the device is kept several inches away from your body. A few inches can make a difference, it notes. Also, put phones on airplane mode when carrying them close as the devices don’t emit RF energy when in airplane mode.
5. Never sleep with your phone under your pillow or near your head. Karen Smith from the state health department suggests keeping your phone at least an arm’s length away from your body when sleeping. You should also turn your phone off or on airplane mode while you sleep, the guidelines note.

I adore potato chips, I drink fresh-ground dark-roast coffee everyday, and I'm still a smoker.... I'm totally screwed.
