Electromagnetic Waves: Harmful or Not So Much?

Our planet has always been surrounded by electromagnetic waves, such as sunlight, starlight, infrared radiation (heat), ultraviolet rays, and natural radio waves emitted by Earth and the cosmos. From the late 19th century onward, the artificial production of electromagnetic waves began, like the laboratory creation of radio waves. Today, we live inside a true "bubble" filled with electromagnetic waves ranging from solar rays to radio/TV transmissions, the Internet, cell phones, microwaves, Wi-Fi signals, Bluetooth, satellites, and photoelectric devices. That's why alarmists claim that this web of waves harms us. Is it an exaggeration? Let’s discuss the topic.
First of all, for information purposes, the value of an electromagnetic wave is measured by its wavelength. For example, if we stir a stick in a lake, we’ll see the propagation of small waves. But if we do the same thing with a log, larger waves will reverberate. In music, a bass guitar resonates with very long waves, while a flute produces much shorter waves. In simple terms, waves are electromagnetic oscillations made of the same "substance," differing only in terms of wavelength or distance.
For more pragmatic reasons, I left out in the introduction the mention of mental or thought waves, which — whether materialists like it or not — exist (just recall the phenomenon of "Remote Viewing" that I once wrote about on the blog Ufology Side B). Not to mention other non-physical phenomena like bilocation, out-of-body experiences, telepathy, or telekinesis, which seem to result from electromagnetic waves generated by humans.
Thoughts Also Emit Electromagnetic Waves
A simple explanation to better understand how thought "leaks out" beyond physical boundaries could be this: since neurons communicate through electrical impulses, and this electrical activity can be measured by devices like an EEG (electroencephalogram), this connection generates brain waves that emit specific frequencies according to current mental activity, categorized as:
Delta (0.5 – 4 Hz): deep sleep
Theta (4 – 8 Hz): deep relaxation and meditation
Alpha (8 – 12 Hz): calm but alert state
Beta (12 – 30 Hz): active attention
Gamma (>30 Hz): intense cognitive processing
Although these are electrical oscillations and not exactly the same as radio or microwave electromagnetic waves, they still involve moving electrical charges — meaning they generate some type of electromagnetic field.
So, How Exactly Should We Define Thought Waves?
Now, entering a more metaphorical or interpretative field — which I’m quite inclined to support — when we hear or read that "thoughts have vibrations," it generally refers to emotional states or altered levels of consciousness (whether self-induced or caused by substances that "help" expand consciousness temporarily).
Even though there is no scientific proof yet to fully explain these extracorporeal phenomena, we are surrounded by evidence (like Remote Viewing). That’s why, fascinated by this mysterious topic, I tried to explore it further in my article Exploring the Essence of Consciousness.
Other "Emissions" of Electromagnetic Waves (Holistic or Esoteric)
Some areas of so-called "Energy Medicine," like Reiki and other practices involving the unified field of consciousness, speak of "thought vibrations" aimed at healing the patient.
Even Quantum Physics sometimes justifies theories based on the idea that the "mind collapses reality." As mentioned before, without solid empirical proof, these subjects remain in the realm of speculation.
One Thing Is Certain: THOUGHTS POSITIVELY OR NEGATIVELY AFFECT OUR INTERNAL AND EXTERNAL ENVIRONMENT.
Speaking of “good and bad,” let's finally look at both sides of electromagnetic waves in the terrestrial environment.
Beneficial Electromagnetic Waves
Visible light — Enables vision, regulates circadian rhythm, and stimulates vitamin D production (through sun exposure).
Infrared — Used in physical therapy to relieve muscle pain and improve circulation.
Microwaves (in low doses) — Safely used in communications (Wi-Fi, cell phones) and food heating.
Radio waves — Essential for radio, TV, telephone, and internet transmissions.
Harmful Electromagnetic Waves
The degree of harm appears primarily with excessive exposure, that is, prolonged exposure or when the waves carry higher energy:
Ultraviolet rays (UV) — Cause sunburns and increase the risk of skin cancer.
X-rays — Exposure must be controlled due to the risk of genetic mutations.
Gamma rays — Extremely energetic and cause severe cellular damage; used, for example, in radiation therapy.
5G, Wi-Fi, and Cellphone Signals: Villains or Not Really?
First of all, we must be aware that these three technologies use non-ionizing radiation (low energy), theoretically harmless to living beings. Even so, it's good to stay alert, especially if used excessively. In other words, although there are no conclusive studies confirming major health risks, caution is always wise.
I still believe that the controversy surrounding the alleged harms caused by 5G, Wi-Fi, and cellphone signals stems much more from a mix of unfounded concerns, inconclusive studies, and, of course, misinformation fueled by doomsayers.
However, to avoid being accused of bias, I decided to dig deeper into the subject and found some interesting hypotheses that, I must admit, shouldn’t be entirely dismissed.
After All, Non-Ionizing Radiation Is Still Radiation!
According to one group of researchers, non-ionizing waves emitted by 5G, Wi-Fi, and cell phones do not carry enough energy to break chemical bonds or directly damage DNA.However, those who disagree argue that chronic and cumulative exposure to these technologies could cause subtle biological effects, especially when devices are used close to the body (e.g., phones held to the ear, carried in pockets, or near the bed).
Possible consequences of such radiation might include:
Increased oxidative stress in cells
Changes in brain activity (especially during sleep)
Interference with cellular calcium channels
Localized thermal effects (micro-heating)
Some people even report symptoms like headaches, fatigue, or nausea when near electronic devices, a condition known as "electromagnetic hypersensitivity."
Impact of Electromagnetic Waves on Animals and Insects
There are studies suggesting that radiation from cellphone towers and Wi-Fi might:
Interfere with the navigation systems of birds and bees (magnetoreception)
Affect the behavior or reproduction of certain insects and small animals
To my understanding, in some cases, the exaggerated alarmism can be attributed to the so-called "Nocebo Effect" (expecting harm and the body responding negatively). But as I said, we should not be careless, especially regarding vulnerable groups such as children, pregnant women, and pets sleeping close to routers.
Conclusion
One thing is certain and undisputed: electromagnetic waves play a fundamental role in our daily lives. Thanks to them, we have technological advances in several areas such as communication, medicine, agriculture, and many others crucial to humanity's development.
In humans, for example, their therapeutic application, such as in MRI scans and phototherapy, shows undeniable benefits. In plants, certain wavelengths favor photosynthesis and growth, and in animals, they assist in disease detection in monitored environments.
Most scientific communities and health agencies (WHO, ANVISA, FDA, etc.) claim that, despite all the noise, the evidence so far does not indicate severe health risks. Again: as long as exposure is not excessive.
There are even ongoing projects aimed at creating filters to isolate — or reduce — the effects of prolonged exposure. There’s still a lot more to come on this topic.
