EMF: We live in modern era where we get used to the conveniences of it. But not many of us are aware that there are health risks which are presented by the gadgets which make our world work. There are many studies in which are noticed that computers, Wi-Fi routers, microwaves and cell-phones send out a stream of invisible energy waves so this is a reason why they are concerned about it .
It is known that since the beginning of the universe, the sun has sent out waves which create electric and magnetic fields (EMF) or radiation. At the same time, the sun sends out EMFs and we can see energy radiating out and this is known as visible light. In the 20th century, the electric power lines and indoor lighting spread across the world. Doctors have realized that the power of lines supply all the energy to the world’s population was sending off EMF’s, just like the sun naturally does.
As the time passed, scientists have learned that many appliances which use electricity also create EMFs like power lines do. Also, there are some studies in which are shown that X-rays and some medical imaging procedures, like MRIs are making electric and magnetic fields EMF. The World Bank has said that 87% of the world’s population has access to electricity and uses electrical appliances in this modern era .
This is a lot of electricity and the EMFs are created all around the world. But even with all those waves, scientists do not think that EMFs are a health concern. Most people do not believe that electric and magnetic fields EMFs are dangerous but there are some scientists who question exposure. Many experts say that there are not enough research whether EMFs are safe.
There are some studies in which are said that EMFs can affect your body’s nervous system function and it can cause damage to cells . Cancer and unusual growths can be symptoms of very high EMF exposure. Also, there can be other symptoms, such as
- There can be changes in an electroencephalogram (which measures electrical activity in the brain)
- Skin burning and tingling
- Restlessness and anxiety
- Loss of appetite and weight loss
- Changes in memory
- Lack of concentration
- Dysesthesia (a painful, often itchy sensation)
- Tiredness and fatigue
- Depression and depressive symptoms
- Sleep disturbances, including insomnia
The symptoms of the EMF exposure are vague. The diagnosis from symptoms is unlikely. It is still not enough known about the effects on the human health. On the other hand, there are some studies in which are said that the electric and magnetic fields EMF is not causing any adverse health effects so we should feel safe using cell phones and appliances. According to this study, we should feel safe if you live near power lines because the EMF frequency is very low .
You should receive X – rays which are medically necessary and you should limit your time in the sun so in this way you will reduce the high – level exposure and associated risks. You should be aware of the electric and magnetic fields EMF and you should reduce the exposure to it. You should put you phone down when you are not using it. You should use speaker function or ear buds so it does not have to be by your ear.
It is known that there are two types of electric and magnetic fields exposure. The low – level radiation is also called non – iodizing radiation. It is mild and it is thought to be harmless to people. The power lines and MRIs and appliances like Wi-Fi routers, cellphones and microwave ovens, send out low – level radiation. The high – level radiation is also known as ionizing radiation.
It is the second type of radiation. This type of radiation is sent from the X – rays from medical imaging machines and it is sent out in the form of UV rays from the sun. The intensity of the electric and magnetic fields decreases as you increase your distance from the objects which is sending out waves.  Here are some common sources of electric and magnetic fields EMFs which range from low – to high – level radiation:
- Non – ionizing radiation:
- Power lines
- Bluetooth devices
- Wireless (Wi-Fi) routers
- House energy meters
- Microwave ovens
- Iodizing radiation:
- X – rays
- Ultraviolet light
