Before investigating a location, please do some background checks on the location. Consider this as critically important. Mobile phone masts and electrical pylons can affect someone who has long term exposure to the electromagnetic field (EMF) emitted from both of these devices. We live in a world that has multiple electrical items such as microwave cookers, washers, dryers etc and they can affect the electromagnetic field that surrounds us. This in turn can make a person exposed to this increase in electromagnetic field feel unwell, uneasy as well as general well-being. As detailed in 'TOOLS OF THE TRADE' always carry out an EMF check using an accurate meter so you can either rule it out or rule it in.
