Microwaves are the layman's term given to electromagnetic fields. EMFs are released by virtually every device that is electronic, meaning many objects in your home and office, such as appliances, lamps and computers, release EMFs. EMFs are also released by the wiring in your home in smaller amounts, and power lines, which is why people often do not wish to live under power lines or hydro poles.
Before deciding which devices to use to block and redirect EMFs in your home, it's important to determine the rates of EMFs in each room. It's possible to buy EMF detection devices that display EMF levels or arrange for a visit from a technician who specializes in EMF detection and blocking to take the readings for you. Once you or the technician determines the extent of the EMFs, take steps to block them.
A variety of companies sell devices that help you block EMFs. If you can't find a company with technicians in your city, buy products from an online retailer and install them yourself. Blocking products include special paints to use in your rooms, sheer-style material to hang on your walls and clear window adhesives to stick to windows.
In addition to using blocking products to secure your home, prevention is another important step to take. Tour your home and look for electronic devices. Because they all emit EMFs, each is contributing to the EMF levels in your home. Unplug devices when you are not using them and limit your use of unnecessary wireless items, such as wireless telephones and computer routers.
