We live in a world enveloped by electromagnetic fields (EMFs) from most modern man-made sources: cell phones, Wi-Fi routers, power lines, household appliances, and so on. The more developed, the more dependent on technology, the more in danger of radiation by EMFs. Despite the fact that EMFs are integral to modern technologies, new evidence is emerging which proves that indiscriminate and unlimited exposure to radiation by EMFs can have a noxious effect on human health.
The Biological Impact of EMF Radiation
Oxidative stress is a major mechanism by which EMFs can exert their effect. EMF has the potential to elicit the formation of reactive oxygen species (ROS), which cause damage to structures within the cell, such as DNA, proteins, and lipids. In the long run, this process is associated with the eventual development of numerous health challenges, including chronic diseases and acceleration in the aging process.
Effects on Neurological Health
The brain is more susceptible to EMF radiation because of its high electrical activity and its location in the head, where most of the frequently used gadgets such as cell phones are placed. There have been several studies linking EMF exposure with alterations in the functioning of the brain, disruption of sleep, dementia, and even dysfunction of the cognitive processes. Of great concern is the impact this might have on children and adolescents, whose developing brains are much more vulnerable to EMF radiation. Research findings have indicated that exposure to EMF can change the neurotransmitter levels along with cognitive functions, therefore raising concerns about long-term neurological health.
Risk of Cancer
Cancer risk is the most controversial and also one of the most researched areas related to EMF radiation. In 2011, the International Agency for Research on Cancer classified radiofrequency EMFs as "possibly carcinogenic to humans" in Group 2B. This conclusion was based on the limited evidence associated with an increased risk of glioma, which is a malignant type of cancer in the brain, in persons who use wireless phones. Although definite conclusions are not possible, ongoing research keeps probing the potential association between EMF exposure and the risk of cancer.
Effects on Reproductive Health
EMF radiation has also been held responsible for several reproductive health complications. Studies have found that exposure to EMFs lowers sperm quality; thus, their viability and motility may be hampered, and this could lead to male infertility. Further, the influences of EMFs on fetal development are well studied. Controlled animal research demonstrated that in animals subjected to prenatal exposure to EMFs, their offspring had abnormalities and behavioural changes. While much more research is needed to understand the full implications for human reproductive health, these results suggest a reason for caution, especially for pregnant women.
Prevention
EMF exposure can be minimized by general and simple measures like keeping a small distance from some electronic devices, using the speaker of the phone set or earphones for calls, and reducing the time spent with Wi-Fi and other Wi-Fi-enabled electronic gadgets, particularly within the sleeping area. Further, there is a technological advancement in EMF shielding products that offer a shield against further possibilities of radiation exposure.
Conclusion
While the benefits of modern technology continue to be advanced, the health risks that come from EMF radiation need to be counted and tackled. Ongoing research is key to a full comprehension of the extent of this risk and the development of measures to avert the risk. One can act from the probably first exposure not to be overexposed to the radiation and save his or her health in the future.
