The Danger We Cannot Hear: Hypersonic Sounds and the Invisible Burden of Modern Humans
Throughout history, humanity has feared the dangers it could see.
Fire...
War...
Famine...
Yet some risks of the modern age can neither be seen with the eye nor heard with the ear. What's more, they often go unnoticed entirely.
Today, our environment is surrounded not only by electromagnetic fields but also by an increasingly diverse range of invisible environmental stimuli. One of these is high-frequency sound that the human ear cannot perceive — that is, ultrasonic and hypersonic sound.
Some studies published in recent years suggest that the effects of these sound fields may not be limited to the auditory system alone; they may also produce various biological effects on the nervous system, the autonomic nervous system, cellular energy production, and the immune system. Of course, research in this area is ongoing, and not all questions have been answered yet. However, the existing findings are significant enough to warrant careful consideration.
Modern Humans Are Under Constant Environmental Exposure
Twenty years ago, people did not live as intertwined with intensive technological systems as they do today.
Today, however;
-
High-speed transportation systems,
-
Industrial production facilities,
-
Powerful ventilation systems,
-
Data centers,
-
Smart home technologies,
-
Ultrasonic sensors,
-
Security systems,
-
Various electronic devices
have become a natural part of our daily lives.
The human ear can perceive sounds roughly between 20 Hz and 20 kHz. The fact that we cannot hear frequencies above this limit does not mean they are completely without biological effect.
Where Does Regulatory Disruption Begin?
There is a clinical picture I have encountered frequently in my practice in recent years.
The patient's laboratory results are largely normal.
No significant problem is seen on MRI imaging.
Blood values are within the reference ranges.
Despite this, the person does not feel well.
They are constantly tired.
Their sleep quality has declined.
They experience headaches.
Their concentration has decreased.
Heart palpitations and an unexplained feeling of unease can occur.
At this point, it is necessary to focus not only on the organs but also on the organism's regulatory capacity.
Because a human being is not merely a system made up of biochemical processes; it is also a biophysical organism.
Why Is the Autonomic Nervous System Important?
As I discuss in detail in my book Regulated Life Longevity, the balance center of the organism is the autonomic nervous system.
This system coordinates;
-
Heart rhythm,
-
Vascular tone,
-
Sleep regulation,
-
The digestive system,
-
The immune response,
-
Hormonal balance.
When the burden of environmental stress increases, the organism can remain in a state of alarm for a long time. The sympathetic nervous system becomes dominant while the parasympathetic system is pushed into the background. As a result, the regulatory effect of the vagus nerve can diminish.
Despite resting, the person cannot feel renewed. Sleep loses its restorative quality, and over time, the risk of developing chronic inflammation may increase.
Mitochondria and Silent Energy Loss
Mitochondria, the energy production centers of our cells, are quite sensitive to environmental stress factors.
Today, aging research shows that disruptions in energy production may play an important role in many chronic diseases.
Under heavy environmental burden;
-
Oxidative stress may increase,
-
Free radical production may rise,
-
Mitochondrial efficiency may decrease,
-
Communication between cells may be negatively affected.
These changes can contribute to a decline in energy capacity over time. It is thought that these mechanisms may play a role in some people who experience unexplained fatigue, difficulty concentrating, and reduced performance.
The Delicate Balance Between the Gut and the Brain
The gut-brain axis, which I discuss in detail in my book The Emotional Brain-Gut II, is one of the important systems affected by environmental factors.
Modern humans do not experience only psychological stress; they are also constantly exposed to environmental stimuli.
This situation can indirectly affect;
-
Intestinal permeability,
-
The microbiota,
-
Histamine metabolism,
-
The immune system.
Disruption of the intestinal flora can further reduce the organism's capacity to adapt to environmental stress.
The ECM: Silent Communication Between Cells
In regulation medicine, the Extracellular Matrix (ECM), which serves as the living space between cells, is of great importance.
The ECM is one of the fundamental components of the communication network between cells.
The transport of nutrients, the removal of metabolic waste, and the exchange of information between cells all take place through this environment.
Chronic inflammation, environmental burdens, and toxic buildup can negatively affect the functions of the ECM. For this reason, today it is becoming important not only to protect against disease but also to maintain healthy communication between cells.
What Can We Do?
Rather than fearing new technologies, we need to be conscious of them. While technological developments improve quality of life, it is important that their potential biological effects also be scientifically evaluated.
Within the scope of a preventive approach;
-
Sleep hygiene should be given careful attention,
-
Unnecessary technical exposure should be reduced,
-
Living spaces should be regularly ventilated,
-
Time spent in nature should be increased,
-
Regular physical activity should be performed,
-
An anti-inflammatory diet should be adopted,
-
The intestinal microbiota should be supported,
-
The balance of the autonomic nervous system should be preserved.
In this process, neural therapy, acupuncture, breathing exercises, HRV-based approaches, and regulation medicine applications can be considered, in suitable patients, among the methods that support the organism's adaptive capacity.
The Real Danger Is Not Always What We Can Hear
The history of medicine has taught us important lessons.
At one time, cigarettes were thought to be harmless.
Asbestos was considered safe for many years.
The effects of environmental toxins on health were only fully understood years later.
Scientific research into hypersonic and ultrasonic environmental exposure is also ongoing. We do not yet know the answers to all the questions; but we must not overlook the possibility that the human organism can be affected not only by environmental burdens it notices, but also by those it is exposed to without ever realizing it.
The medicine of the future will focus not only on treating diseases but also on understanding the invisible relationship humans have with their environment.
Because health is not merely the absence of disease; it is the organism's capacity to adapt to constantly changing environmental conditions.
And the name of this capacity is regulation.
