1. Avoid wireless when possible
EMF in the radio range accumulates, so if possible, choose wired Internet instead of wireless, a wired home security system, and wired entertainment systems. If you do use WiFi, plug in only when needed, and disconnect during sleeping hours. Keep the router as far as possible from your desk and childrenís rooms.
2. Pick safer lightbulbs
Avoid compact fluorescent bulbs, which emit dirty electricity. A CFL saves energy by turning itself on and off repeatedly, as many as 100,000 times per second. Use LED or incandescent bulbs instead. Do not install dimmer switches (rheostats) for the same reason.
3. Stay away from the circuit breaker
Main electrical and circuit breaker panels give off high EMF within 3 to 4 feet. Make sure your bed is safely distant, and keep in mind the panel may be on the floor above or below you or on the other side of a wall.
4. Choose an old-school landline phone
Cordless phones can emit just as much radiation as mobile phones, although only when youíre using them. Consider reinstalling corded (landline) phones. Avoid very powerful digital enhanced cordless telecommunications (DECT) phonesóthe kind with a base station and satellite handsets.
5. Ban Bluetooth headsets
When on a cell phone, use the speakerphone or a wired earpiece (hollow cord types are preferable). Do not use a Bluetooth wireless headset; combined with the phone, it can exceed even the current inadequate safety limits. Give text messaging a try, especially in place of short calls. Itís safer than holding the phone to your head. Do not allow children to use cordless or cell phones, except for emergencies.
6. Skip your cell when the service is spotty
If you struggle to get a signal or tend to drop calls in a certain area (common in elevators, buses, cars, and other enclosed spaces), wait until the signal is stronger. When handling a weak signal, the phone increases power to a maximum, irradiating you and those around you.
7. Donít wear your phone like a beeper
A better place for your cell or BlackBerry is in your purse or briefcase, because electromagnetic field exposure diminishes rapidly beyond 3 feet. Itís okay to carry it on you if the device is in "flight" or "off-line" mode. If you must carry it while fully on, keep the keypad positioned toward your body, so that the battery pack faces outward. Another safety tip: Switch which side of the head you use your phone on from call to call so you spread out exposure.
8. Keep your laptop off your lap
Curling up on the couch with your laptop may be convenient, but EMF experts recommend against it. Many laptops produce a strong electromagnetic field, especially when you use one while itís plugged into an outlet (that means the battery is charging close to where your hands are). Youíre better off unplugging and using the laptop on battery power, then staying away from it while it recharges.
9. Unplug what youíre not using
If your kitchen counter is cluttered with a coffeepot, slow cooker, food processor, or other convenient culinary appliances, keep them unplugged whenever youíre not currently using them. Same goes for alarm clocks, lamps, iPod chargers and other various devices around your home. Anything plugged into an electrical outletóeven a lampóemits an EMF; if unplugged, it will not.
10. Think LCD over plasma
When itís time to upgrade your TV, choose an LCD (liquid crystal display) instead of plasma or the old CRT (cathode ray tube) models. LCDs emit much less radiation, and plasmas can give off transient pollution on your electrical wiring.
11. Get your home tested
If you suspect that your home has high-EMF fields, check if your utility company conducts a room-by-room survey. Itís usually free. Hot spots can be completely shielded with special coverings. If you discover high levels of dirty electricity, consider installing filters (capacitors) that plug into electrical outlets ($35 at lessemf.com).
