EMFs or electromagnetic fields exist everywhere in the environment. In our homes, school, and workplace. With more connected mobile devices on the market than ever and the rollout of 5G, it's crucial to increase our awareness about this all-penetrating technology.
We got used to the conveniences of modern life. But only a few of us are aware of the possible health risks presented by the everyday technologies that make our lives more convenient.
Over the years, scientists learned that many appliances that use electricity also create EMFs. These include to an increasing degree our cellphones, Wi-Fi routers, computers, and 3G/4G/5G towers. They radiate invisible frequencies that some experts are concerned about.
Various human-made sources of electromagnetic fields.
- Electrical appliances
- Cell phones, cell towers, WiFi routers
- Radio communications devices
- AM / FM radio and television
- emergency service radio (police, fire, ambulance)
- air traffic control
- 3G/4G/5G towers
In towns and cities, the technically generated level of electromagnetic radiation, which is typical nowadays, is more than 1 billion times higher than natural EMFs which are necessary for life. This means we are all constantly exposed to electromagnetic frequencies.
Dangers Of EMFs
It is scientifically proven, that EMF radiation causes harmful oxidative processes to manifest within our cells, which have overall negative effects on our health and well-being. This is the primary factor behind accelerated aging and the incurrence of chronic degenerative illnesses.
According to Martin Pall, Ph.D, non-ionizing radiation activates voltage-gated calcium channels (VGCCs) that then release calcium from outside the cell to the inside. These pathophysiological effects are produced largely through excessive calcium ion signaling that leads to excessive nitric oxide (NO), superoxide, peroxynitrite, free radical formation, and consequent oxidative stress.
Many studies suggest that this is the mechanism that leads to an increase of oxidative stress markers and damage to our DNA.
As the biological damage from EMFs is triggered by activating your VGCCs, tissues with the highest densities of VGCCs are at greatest risk of harm. These mainly include the brain, testes, nervous system, SA Node - the "natural pacemaker" of your heart, and the retina.
Below you can find different studies showing the negative effects of EMF radiation on our cells and bodies.
Damaging to Childhood Development
Radiation from Wi-Fi and cellular phones can disrupt normal cellular development, especially fetal development. A 2004 animal study linked exposure to delayed kidney development.  These findings were supported by a 2009 Austrian study. In fact, the disruption of protein synthesis is so severe that authors specifically noted, "this cell property is especially pronounced in growing tissues, that is, in children and youth. Consequently, these population groups would be more susceptible than average to the described effects."  In short, bathing the developmentally young in Wi-Fi increases their risk of developmental issues.
Affects Cell Growth
When a group of Danish ninth graders experienced difficulty concentrating after sleeping with their cell phones by their head, they performed an experiment to test the effect of wireless Wi-Fi routers on garden cress. One set of plants was grown in a room free of wireless radiation; the other group grew next to two routers that released the same amount of radiation as a cell phone. The results? The plants nearest the radiation didn’t grow. 
Derails Brain Function
Other scientists have begun to look at the impact of 4G radiation on brain function. By using MRI technology, they found that persons exposed to 4G radiation had several areas of reduced brain activity. 
Reduces Brain Activity in Females
A group of 30 healthy volunteers, 15 men and 15 women, were given a simple memory test. First, the entire group was tested without any exposure to Wi-Fi radiation — no concern. Then, they were exposed to 2.4 GHz Wi-Fi from a wireless access point for about 45 minutes. During that portion of the testing, brain activity was measured and the women had a noticeable change in brain activity and energy levels. 
We’ve known for a long time that the heat generated by laptops kills sperm. Now it turned out that heat isn’t the only threat to a man’s virility. Research has found exposure to Wi-Fi frequencies reduce sperm movement and cause DNA fragmentation.  Both human and animal testing has confirmed that exposure negatively affects sperm.  
May Impact Fertility
The results of an animal study suggest that some wireless frequencies may prevent egg implantation. During the study, mice exposed 2 hours a day for 45 days had significantly increased oxidative stress levels. The cellular damage and impact on DNA structure from exposure suggest a strong possibility of abnormal pregnancy or failure of the egg to implant.
The Karolinska Institute in Sweden released a warning in 2011, stating:
”Pregnant women are cautioned to avoid using wireless devices themselves and distance themselves from other users, ”
”Current US [and Canada]…standards for radio frequency and microwave radiation from wireless technology are entirely inadequate, ” and
”Safety standards also ignore the developing fetus…” 
Provokes Cardiac Stress
If you think your heart races when surrounded by wireless networks or 3G or LTE cell phones, it may not be in your head. A study involving 69 subjects reported that many of them experienced a real physical response to electromagnetic frequencies. Exactly what was the physical response? Increased heart rate — similar to the heart rate of an individual under stress. 
This is extremely controversial but we can’t ignore that plenty of animal models indicate that exposure to electromagnetic radiation increases the risk of tumor development. While human studies are rare, reports and case studies abound. One such case involves a young 21-year-old woman who developed breast cancer. What makes this case unique was that her family did not have a predisposition to breast cancer… and she developed the tumor right on the spot she carried her cell phone in her bra.
