The radiation you don't see.
Most people know about cell phones. Few realize their homes are filled with EMF sources they never considered—many running 24/7.
Smart meters: The box on your wall.
Smart meters transmit your usage data wirelessly to utility companies. They operate on 900 MHz and 2.4 GHz bands—the same frequencies as WiFi—and they never stop.
Two Types of Radiation
Smart meters emit both ELF (extremely low frequency) radiation from power flow and RF (radio frequency) radiation from wireless data transmission. You get a double dose.
Location Matters
Smart meters are often installed on exterior walls adjacent to bedrooms or living areas. RF signals penetrate walls. If yours is behind your bed, you're sleeping in the beam path.
Mesh Networks
Many smart meters communicate with each other, creating a mesh network. Your meter may relay data from neighbors' meters, increasing transmission frequency beyond just your own usage reporting.
Tip: Many utilities offer opt-out programs to keep analog meters or reduce transmission frequency. Sleep at least 5-10 feet from any smart meter.
Dirty electricity: The invisible pollution.
Your home wiring should carry clean 60 Hz power (50 Hz in Europe). But modern electronics create high-frequency spikes and harmonics that ride on your electrical system—this is “dirty electricity” or electromagnetic interference (EMI).
Sources in Your Home
- • Dimmer switches - Chop the power wave, creating harmonics
- • LED and CFL bulbs - Internal electronics create interference
- • Smart home devices - Constantly communicate on your wiring
- • Inverter appliances - Modern refrigerators, AC units, furnaces
- • Solar inverters - Convert DC to AC, generating EMI
- • Phone/laptop chargers - Switched-mode power supplies
Why It Matters
Dirty electricity radiates from your wiring into your living space. Every wire in your walls becomes an antenna broadcasting EMI throughout your home—24 hours a day.
Simple Test
Turn on an AM radio between stations. Walk around your home. Buzzing, crackling, and interference indicate dirty electricity sources. Louder = worse.
Devices you forgot are transmitting.
Baby Monitors
Digital baby monitors transmit constantly, often at high power to penetrate walls. Placed near a crib, they expose infants to continuous RF radiation during critical development.
Consider: Wired audio monitors or increasing distance.
Gaming Consoles
PlayStation, Xbox, and Nintendo consoles have WiFi that stays active even in “rest mode.” Controllers use Bluetooth. All transmitting while you think they're off.
Consider: Full power-off or wired controllers.
Printers
Wireless printers broadcast availability constantly. Even when not printing, they're transmitting. Often placed in home offices where people spend hours.
Consider: USB connection or disable WiFi in settings.
Smart TVs
Built-in WiFi, Bluetooth for remotes, sometimes even in standby mode. Modern TVs are always connected, always transmitting, even when “off.”
Consider: Ethernet connection, disable wireless features.
Wireless Keyboards/Mice
Bluetooth peripherals transmit constantly to maintain connection. Your hands rest on transmitters for hours during computer work.
Consider: Wired alternatives are cheap and reliable.
Fitness Trackers
Worn 24/7, syncing via Bluetooth, sometimes with cellular. Strapped directly to your body during sleep, exercise, and all day activities.
Consider: Sync manually, remove during sleep.
The “smart home” problem.
Smart thermostats, cameras, doorbells, light bulbs, plugs, refrigerators, voice assistants... each device adds to a layered electromagnetic environment.
These devices don't just transmit occasionally—they maintain constant communication on WiFi, Zigbee, Z-Wave, and Bluetooth. The result is an overlapping web of RF radiation throughout your living space.
Voice assistants (Alexa, Google Home) listen continuously, requiring constant WiFi connection
Security cameras stream video constantly, high bandwidth = high RF output
Smart bulbs in every room create whole-home RF coverage
Mesh WiFi systems are designed to eliminate dead zones—meaning maximum RF coverage everywhere
Your router never stops.
Even when no devices are actively streaming, your router broadcasts beacon signals every 100 milliseconds to maintain connections. This happens on both 2.4 GHz and 5 GHz bands simultaneously.
The Bedroom Problem
Many people have routers in or near bedrooms for better coverage. This means 8+ hours of close-range RF exposure during sleep—when the body should be recovering and repairing.
Simple Solutions
- • Put router on a timer to shut off during sleep
- • Move router away from bedrooms
- • Use ethernet for stationary devices
- • Disable 5 GHz band if not needed
Distance Matters
RF power decreases with the square of distance. Moving a router from 3 feet to 12 feet reduces exposure by 16x. Small changes make significant differences.
Awareness is the first step.
You can't reduce what you don't know exists. Walk through your home with new eyes. Count the transmitters. Consider which ones you actually need.
