EMF Tips

An eco router transmits only when it has to, rather than holding a strong signal all the time. Home levels are already low, so it is a small precaution.

Dual-band routers run two separate transmitters, 2.4GHz and 5GHz. Turning one band off leaves a single radio running, and the connection is often as usable.

Most routers broadcast at a power meant for a large home. Turning the output down in a small space weakens the field everywhere in the house.

A router transmits around the clock, even when nobody is online. Cutting its power overnight removes that source for hours, without changing daytime use.

Connecting a device to the router by cable takes that exchange off the airwaves. The device’s own WiFi radio can then be switched off without losing speed.

A single shortcut that turns off cellular, WiFi and Bluetooth at once makes the habit easy to keep. This walks through building a one-tap radio-off mode.

Reverse tethering gives a phone its connection from a computer over a USB cable. The cellular and WiFi radios can stay off while pages still load.

Plugging a phone into the network with an Ethernet adapter takes its WiFi radio out of the exchange. Other radios in the phone still need to be switched off.

Taking calls with speaker or a headset keeps the phone’s antenna away from your head. Absorption is greatest on the side of the head where the phone is held.

Waking up is the one job most phones do on the nightstand, and a small battery clock can take it over. The phone then spends the night elsewhere.

A phone charging beside the bed has a mains adapter and a live network connection within reach of your head. Charging it across the room increases the distance.

Wireless charging pads work by a magnetic field between two coils. Using a plain cable instead removes that field, though both setups are low level.
