Minimising the time that you hold the phone to your ear can be achieved in many ways - you don’t have to stop making phone calls.
Wi-Fi has become so popular that it is very difficult to escape its effects. Even if you have no Wi-Fi in your house you may be still covered by your neighbours network - in some homes you can even pickup 8-10 neighbourhood networks.
If you are electro-sensitive this may be a problem, it's all down to the signal strength. As the signals become stronger, more people are noticeably affected. The worst space to be in is very close to the Wi-Fi router as the signal strength here is many times stronger than needed to successfully connect.
For other people's Wi-Fi you don't have many remedial options:
For your own Wi-Fi you have more options:
Luckily Wi-Fi has a relatively short range especially with walls in the way - maybe up to 50m (50 yards) in ideal conditions but often down to 5-10 yards/meters in brick buildings.
To use Wi-Fi sensibly to minimise any risk to your health or wellbeing you should bear the following in mind:
Powerline adapters are cheap devices that send your network data over the house wiring, not requiring significant radio transmission.
Reduced EMF Routers
You can turn down the power output of some Wi-Fi routers such as on the high performance Netgear R6400 or the lower cost Netgear W604. Setting the power to as low as 10% of maximum power will reduce the range considerably but will also reduce your exposure to the EMFs. You can experiment with the power setting to find the best compromise, providing low EMFs with just enough power to provide connecivity where you need it.
There are a wide range of cordless phones on the market around the world, using many different types of radio transmission. They all transmit a radio signal when being used and some transmit all the time!
So, in general it is important to use them carefully, treating the mobile part as you would a mobile phone, and the base station as if it were a mini cell tower - i.e. keep it away from your living area or bedroom.
These devices can be extremely useful but … be aware they can affect your health and sleep patterns, so try living without them for a few days and see if you notice any difference.
