According to the current scientific knowledge, electromagnetic fields may have health risks.
These risks can be reduced by practicing protective measures for minimizing adverse effects of technologies we use every day.
TiFaNe rule can serve us well for quick decision-making:
Timely: Use the device for as little time as possible.
Far: Be as far away from the device as possible.
Necessary: Activate only the necessary functions.
(If I can choose) I would prefer:
Cable connection (instead of wireless).
Mechanical or analog device (instead of digital).
Prevention by supplementing vitamins (C, E) and compensation by physical exercise in a clean environment (with as low EMFs as possible).
Place as far as possible from critical structures (head, genitals).
Turn off before sleeping (or use airplane mode).
Call with the speakerphone or wired headphones.
Make calls only at full signal.
Turn off unused functions and applications running in the background (Bluetooth, data collection).
Keep your distance (laptop on the desk).
Turn off Wi-Fi during off-line activities (or airplane mode) and prefer wired internet connection (ethernet).
Wired connection of peripherals (mouse, keyboard).
Turn off when not in use (before sleeping).
Get a low-power model.
Preferably use wired connection from the modem directly to the computer (ethernet cable).
Use only wired headphones.
Prefer a speakerphone.
Prefer personal visit.
Alternatively use wired transmission (webcam).
If wireless is necessary, consider a product with only the necessary functions and prefer an analog device.
Check the surroundings for sources of EM fields:
Mobile tower base stations (BTS).
High voltage lines (HV, VHV) + transformer stations.
Industrial machines and factories.
Find out the number of Wi-Fi networks (eg. with smartphone).
In the case of buying a property:
Study the city development plan.
Test electric sockets with an electrician.
Consider professional EM field measurement.
When constructing a house, consider low-emission design of electrical systems during the planning phase:
Shielded wires.
Circuit break-offs.
Power switch for bedroom.
Very sensitive people may also consider:
Remote location with minimal EM background.
Minor adjustments:
Shielding foil for windows.
Shielding bed net/curtain (elektronic devices then use outside of the shielded premises).
Major modifications (require expertise + expensive materials):
Windows with shielding finish.
Shielding paint for walls or MuMetal foil.
Prefer low power wireless (LoRa, Zigbee) or optical (Li-Fi) communication.
Data should be transmitted at event-driven intervals or on a regular basis as sporadically as possible (hourly/daily for monthly billing cycles).
Consider wired connection if possible (M-Bus, Ethernet, Power line).
Turn off:
Wi-Fi (for off-line apps).
Background updates (update regularly before use).
Prefer wired connection with a computer.
If developing applications, use batch data updates.
Vitamin prophylaxis (C, D, E) before use.
Reduce the time of use (especially until 20 years old) and take regular breaks.
Use only the necessary electronics:
Basic systems always active (on-board computer, power steering/brakes, car lighting, etc.).
When needed, activate additional systems (GPS navigation, assistance functions).
Turn off premium services when not actively used (wireless transmission of analytical data, built-in screens in the seats).
Make phone calls outside vehicle after driving (alternatively handsfree for emergency calls).
When buying a car:
Prefer a model with optimal electronic accessories (only systems that you need).
Instead of an electric car, consider model with emission-free internal combustion engine (bio-LPG, hydrogen, synthetic gasoline).
Prefer a photo-composite filling.
As fixed braces prefer foil braces (expensive) or removable braces (if possible).
