You have probably heard of electromagnetic fields, and you may even know that they are invisible magnetic and electrical forces which come in wave form. You may also know that EMFs are natural, and we can find them in the earth’s atmosphere. We humans also create electromagnetic fields in our bodies. But what is so special about electromagnetic fields that they have become a hot topic of debate amongst many? Here’s everything you need to know about electromagnetic fields – and how exposed we are to EMFs in our daily lives.
The basics on electromagnetic fields
Electromagnetic fields are created by nature and by humans, and as you can rightly guess, it’s the non-natural fields which concern us most. Nature produces electromagnetic fields with the building-up of electrical charges in the earth’s atmosphere (which you can see in thunderstorms). You can also find many stones which are magnetic, and the Earth itself has a magnetic field covering it.
But non-natural electromagnetic fields are a different matter. There are various products which have electromagnetic fields, and these include televisions, microwaves, computers and laptops, lights, and other electronic appliances and gadgets. But there are elements which can produce a lot of high-frequency electromagnetic fields, such as cell phone towers, towers used for broadcasting transmissions from radio and television stations, cell phones, and more.
Devices with low-frequency electromagnetic fields
There are many devices and gadgets which can emit low-frequency electromagnetic fields; in fact, we are surrounded by them. If you take a look around your home, you will understand what we mean. For instance, your television is a source of low-frequency EMFs, and so is your answering machine. Another source of low-frequency EMFs is your microwave oven, and yet another is your stereo or radio. There are other sources of low-frequency EMFs: alarm clocks, DVD players, washers and dryers, portable heaters, refrigerators and freezers, electric cookers and ovens, electric blankets, computers, hair dryers, copy and fax machines, printers, fluorescent lights, and electrical panels where the electricity enters your home.
Devices with high-frequency electromagnetic fields
There are devices which emit high-frequency electromagnetic fields, and you may already be aware of one important device: the cell phone. But there are other devices as well, and the list includes cordless telephones, pagers, wireless routers, Bluetooth devices, laptops, wireless monitors used for babies, two-way radios, and smart meters.
Are electromagnetic fields dangerous?
A question that is debated all over the world is whether or not electromagnetic fields are dangerous. While we need to do further studies, the consensus is that electromagnetic fields can have a detrimental effect on the body. The World Health Organization itself confirms that electromagnetic fields at a higher level may have a biological impact. Experiments performed on healthy individuals showed that short-term EMF exposure in present home environments does not have any apparent adverse effect, but exposure to a higher level of EMFs may become harmful. Since most people have wifi that goes throughout their homes and workplace it is a safe bet to invest in a wifi radiation blocker.
But even as studies are still not that extensive, it’s always best for us to prepare. You can benefit from specially-made EMF protection products which are available online and which you can wear on your body. There are also products which can work as a shield for cell phones and other devices.
