Electrosmog protection at home: The 3 best tips

In our modern, high-tech world, we are practically constantly exposed to low-frequency electric and magnetic direct and alternating fields as well as high-frequency electromagnetic radiation. Don't worry: no one has to do without the blessings of modern technology. The best tips on how you can take electrosmog precautions yourself at home can be found here!

Tip number 1: Set up WLAN with low radiation levels 

No question: WLAN is practical. But did you know that you are exposed to up to 205,000 µW/m² when using "normal" WLAN? The SBM guidelines already label 1000 µW/m² as extremely noticeable exposure - a factor of 200 lower than the exposure we are exposed to in reality.  

If you don't have the possibility to use wired Internet at home, you can already take personal precautions by making some simple settings on your router: 

  • Set time switching:  
    During the night, WLAN is usually not needed. You can use the router software to set times when the WLAN is switched off. In this way, you avoid unnecessary exposure to radiation, especially at night when the body is supposed to regenerate during sleep. 
  • Reduce transmitting power: 
    Most routers are preset to the highest possible transmission power at the factory. In most cases, however, this is not necessary. The transmission power can be adjusted in every router - and that's exactly what you should do. Even significantly lower intensities are sufficient for good functionality. 

There are now WLAN routers that offer "Full-Eco-WLAN": This means that the router switches off the WLAN when the registered end devices no longer need it/the user logs out. This also means that no more standby signals are sent. Normal routers also emit a 10 Hz signal in standby mode - the characteristic "knocking" when the signal is detected via audio function with a high-frequency analyzer. With Full-Eco-WLAN, this signal is no longer transmitted.

Tip number 2: Set smartphones correctly 

We are constantly reachable and always under voltage. But even smartphone manufacturers (Samsung, for example) warn that using them right before bedtime can have a negative impact on our sleep patterns. With many smartphones, you can set up a night or do-not-disturb mode. This allows you, for example, to automatically activate the blue filter - so you avoid the short-wave, blue-tinted light influencing melatonin production.  
Melatonin, the so-called sleep hormone, ensures that our body "shuts down" at night and that we can regenerate ideally. In addition, you can automatically activate the "do not disturb" mode in your resting time - the reception power of your phone is automatically shut down, you can even automatically switch to airplane mode. This is the best way to protect yourself from high-frequency radiation exposure during sleep - and important calls will still reach you.  Note: Unfortunately, this does not work with all smartphones. If you use an iPhone, you always have to switch off WLAN and Bluetooth manually - airplane mode is no guarantee that WLAN and Bluetooth are really switched off.

Tip number 3: Check the plug 

Hard to believe but true: You can plug in plugs "wrong". In a normal Schuko socket there are 2 "holes" for inserting the plug. On one of the contacts is the phase, on the other the neutral. On the two "lugs" at the top and bottom of the socket lies the green-yellow protective conductor. 

If a device with a separate switch, such as a bedside lamp, is connected to the socket, this can lead to two scenarios: 

In example 1, the connected device generates a high electric field even when switched off, since the entire device is "live." In example 2, a well measurable electric field is generated only on the very short distance to the switch - and much less stress for someone who wants to sleep with his head right next to the bedside lamp.  


We are convinced that everyone should take precautions! Not everyone feels the effects of electrosmog directly or even physically - nevertheless we are exposed to high and low frequency electromagnetic fields on a daily basis. With a few simple tricks you can drastically reduce your exposure to electrosmog at home - and you don't even have to spend money. With our home meters, e.g. the HF35C for high frequency and the ME3830B for low frequency, you can make your first own measurements to see how efficient your measures are and effectively protect yourself and your family!
