• Use your cell phone only when necessary, and don’t chat long. If you’re not expecting a call, turn the phone off. Otherwise, your phone checks contact with the nearest tower regularly, and that contact draws full power.
• Though Bluetooth headpieces have 100 times less radiation than the phone itself, it is advisable to remove it from your head when not talking.
• If possible, strategize to use your phone in areas with the best signal. Powerwatch.org claims this may reduce emissions by up to 500 times. Also, when indoors use your phone near a window, with it between your body and the window.
• Talking in a car or train should be avoided. Not only is it a distraction that could lead to accident, but the vehicle’s metal frame may trap the radiation, magnifying it.
