The influence of electromagnetic fields (EMF) radiation of a certain strength on the human body cannot go unnoticed. After all, the principles of functioning of organs and systems based on electrical phenomena are inherent in man himself. The brain, central and peripheral nervous system are the first objects that can be affected by external fields, not to mention undesirable effects in other parts of the body and changes occurring at the cellular level. As experts in the field of scientific hygiene have found, an electromagnetic field of sufficient intensity can change the pattern of higher nervous activity of the human brain.
Sources of radiation
Technogenic sources of electromagnetic fields are numerous.
First of all, these are power plants, electrical substations and high-voltage lines. Even an ordinary city streetcar, subway car and electric train generates very powerful electromagnetic radiation, and not least because of this the work of streetcar drivers and drivers is categorized as “with special working conditions”.
Apartment wiring also generates an electromagnetic field; but, looking ahead, we note that it has virtually no effect on the body – the field is too weak.
Wireless communication devices are sources of electromagnetic fields. Electromagnetic radiation, the power of which is tens to hundreds of times greater than the power of the natural background, creates microwave ovens, hair dryers, electric shavers and most other household appliances.
Any radar installations, radiating antennas of any type also generate the strongest electromagnetic field.
Effects of electromagnetic fields on the human body
The human body accepts natural electromagnetic fields, but an increase in their strength – for example, during magnetic storms on the Sun – can impair the health of immunocompromised, elderly and “weather-sensitive” people. Similarly, the body reacts to artificial electromagnetic fields, which can be much stronger than natural radiation. Human tissues are composed of water and are conductors of electricity, so the body responds to electromagnetic fields with a weak electric current. The magnitude and type of current depend on the frequency and power of the field source.
Exposure to strong fields causes unpleasant symptoms such as:
- Fever Increase in temperature
- Fatigue
- Irritability
- Sleep disorders
- Memory and attention problems
Prolonged exposure can lead to more serious consequences:
- Migraine
- Infertility (men and women)
- Pregnancy problems (miscarriages)
- Central nervous system disorders in children
- Brain cancer
Electromagnetic fields pose a danger to all living things, which is why the term “electromagnetic pollution” has emerged.
How to protect yourself from electromagnetic radiation
In everyday life it is impossible to completely avoid electromagnetic radiation, which “hangs in the air”. However, by following a few simple recommendations, you can significantly reduce its impact. Here are the main protective measures:
- Keep safe distances: do not stand next to a microwave oven, do not sleep next to a Wi-Fi router (it should be turned off when the Internet is not needed).
- Place furniture and electrical appliances correctly: don’t put your bed next to a wall with a refrigerator, computer or TV behind it, as walls don’t block low-frequency radiation.
- Don’t hold your laptop on your lap.
- Reduce the amount of time you talk on your cell phone, taking breaks if the conversation lasts more than 15 minutes.
- Use a landline phone whenever possible.
- Avoid being near high-voltage power lines, transformer stations, radar installations and antennas (except indoor antennas) for long periods of time. It is especially dangerous to be near the focus of a parabolic antenna.
For people whose work involves sources of electromagnetic radiation, it is important to follow special safety rules to minimize the risks. Usually, such occupations are considered hazardous, and workers receive additional benefits and opportunities to restore their health.
Additional risks and protection against electromagnetic radiation
Prolonged exposure to electromagnetic fields, even if mild, can have a cumulative effect, disrupting cellular metabolism and weakening the immune system. This can lead to chronic diseases and precancerous conditions, as well as impair the function of organs and tissues.
Children whose bodies are not yet fully formed are particularly vulnerable. Their tissues and immune systems are more susceptible to electromagnetic radiation, which increases the risk of various diseases. To ensure the safety of children, it is important to limit their contact with EMF sources and choose low-emitting devices that meet modern safety standards.
Electromagnetic fields and their influence on psycho-emotional state
In addition to physical symptoms, electromagnetic fields can also affect a person’s psycho-emotional state. Some studies show that prolonged exposure to electromagnetic radiation can cause increased levels of stress, anxiety and depression. This may be due to disorders of the central nervous system, as well as changes in the chemical composition of the brain.
People exposed to strong EMFs may experience mood deterioration, nervousness, and decreased concentration. It is important to note that these symptoms may be reversible if exposure to electromagnetic radiation is minimized.
Conclusion
The effect of electromagnetic radiation on human health is an important and multifaceted problem that requires attention and scientific research. Modern society inevitably faces high levels of electromagnetic fields as they are part of our daily life and industry. Although exposure to electromagnetic radiation does not cause immediate or noticeable illnesses in most cases, prolonged or intense exposure can lead to various physical and psycho-emotional disorders. This emphasizes the need to develop stricter regulations and standards to protect human health, as well as to raise awareness of the risks associated with electromagnetic pollution. It is important to follow simple protective measures to minimize exposure to EMFs and thus maintain health in the technological environment in which we live.
