The human body caught between reels and reality!

One of my top priorities is understanding the world through the lens of the human body and biology.

There is a law of correspondence: as above, so below; as in the macro, so in the micro.

According to this principle, if we understand what we see, if we learn to decode it, we can perceive the universe even within a living cell or a feather lying on the asphalt.

I’ve stepped away from the classical form of medicine, but not from its essence. I continue to seek answers in the body—not just for various pains, but for systemic topics in general—because, after all, Earth and its biosphere function like a living super-organism, self-regulating its temperature, atmospheric composition, ocean salinity, and other vital conditions for life, through complex interactions between living organisms and the physical environment.

A client told me recently that she and her office colleagues get their health and illness information from certain therapists who post reels on various social media platforms.

Among other things, she’s learned that it’s important to stimulate the parasympathetic system and the vagus nerve daily through various techniques—from breathing and physical exercises to nutritional supplements and microbiome management—in order to support tissue repair, even regeneration, biohacking, and metabolic reversal.

These are good and useful, but incomplete!

Biology doesn’t get fooled.

Everything in the body (to put it very briefly) is about energy management—about what we take in and what we eliminate, about the fine balance of subsystems—not about one nerve or one isolated parasympathetic function.

Fortunately, medicine cannot be confined to a reel. Not in one, not in two, not even in twenty.

A video is not a consultation and certainly not a universally applicable treatment, even if later discussed with a specialist.

Symptoms are individual—not viral content.

The life in our bodies isn’t a linear mechanic that can be explained in 15 seconds... or even 15 volumes.

The vagus nerve story—though supported by many recent theories—is only a partial truth, and it may keep you away from the actual causes of your imbalance.

The vagus nerve is just a small part of the vast neural network of the body.

Human metabolism, which sustains life, is a true nonlinear differential equation, with many unknowns still undeciphered.

Physiological imbalance is not a missing piece, but a dysfunction within an interconnected mechanism.

The fine tuning between cranial nerves, the endocrine system, metabolism, microbiome, emotional state, circadian and cosmic rhythms is a symphony—not an isolated sound.

Let’s take a functional look at the nervous system together.

The nervous system can be more easily understood based on the type and location of processed information, not just its anatomical structure.

Such a functional classification includes: the Central Nervous System (CNS), Peripheral Nervous System (PNS), Enteric Nervous System (ENS), and Autonomic Nervous System (ANS).

Each branch has distinct roles:

➤ Central Nervous System (CNS):

It is the main information processing center. It integrates physiological needs and coordinates responses.

Includes: gray and white matter, cerebral hemispheres, cerebellum, and spinal cord.

➤ Peripheral Nervous System (PNS):

Manages external information and reactions to the environment.

It is made up of sensory and motor nerves that transmit stimuli to and from the CNS.

➤ Enteric Nervous System (ENS):

Located peripherally, internally, within the abdominal viscera, it regulates digestive functions.

It works semi-autonomously but is directly connected to both the CNS and ANS.

➤ Autonomic Nervous System (ANS):

It has projections throughout the body and connects to all systems.

It integrates automatic body functions by linking terrain management with internal and external demands (terrain = functional expression of structural constitution in its internal balance, in response to endogenous and exogenous stressors).

It has three particular branches:

• Parasympathetic (πΣ): The only initiating branch, it conceptualizes and asks the rest of the network for strategies to maintain the basal balance of metabolism and the neuro-immuno-endocrine system.

• Alpha-sympathetic (αΣ): Calibrates responses, plans, congests, and manages the duration, intensity, or endurance of metabolic processes.

• Beta-sympathetic (βΣ): Completes, concludes, contracts, excretes—“puts a period” at the end of sentences initiated by the previous two sisters—through the release of adrenaline.

Each branch uses specific receptors (para, alpha, beta), neurotransmitters, and autacoids (a kind of autonomous chemistry for the autonomic system).

Autacoids are locally produced chemical substances that act at the site of production and significantly influence physiology.

Among the now well-known autacoids used by the ANS are:

• Serotonin – autacoid, neurotransmitter, hormone.

As an autacoid, it prolongs parasympathetic activity (πΣ) by delaying norepinephrine release in sympathetic neurons.

(It may seem like living in constant “para” would mean continuous well-being, but it doesn’t—severe imbalances appear in other neuroendocrine dynamics.)

As an enteric hormone—95% produced and used in the digestive tract—it regulates intestinal motility, glucose absorption rate, and delays insulin release. This peripheral action supports its central neurotransmitter role, opposing insulin and promoting brain access to blood glucose.

• Histamine – supports alpha-sympathetic neuron activity. It is both an autacoid and a neurotransmitter.

It prolongs norepinephrine’s constrictive effect on cardiovascular, respiratory, and digestive systems.

It is a pro-inflammatory factor—the more intensely it is expressed, the more sustained alpha-sympathetic (αΣ) activity becomes, and as a result, beta-sympathetic (βΣ) response also intensifies.

The PNS and ENS detect the quantitative nature of the challenge, the CNS analyzes the qualitative nature of the stimuli, and the ANS calibrates the intensity of the response.

I’ve oversimplified the anatomy and physiology of the nervous system—which cannot be contained in even the most generous of “embraces.”

What I’ve tried is to form an objective perspective on what can fit into a reel or a post—almost nothing!

I didn’t aim to shatter illusions, but only to bring a dose of realism and clarity into this never-ending saga of fanciful information and misleading oversimplifications promoted on social media.

When it comes to your body, seek expertise.

Seek people who have studied, who continuously research, who can offer a systemic and comprehensive explanation for the physical and/or psychomental discomfort you’re experiencing.

Real knowledge requires time, patience, observation, and discernment.

Use social media as a starting point for questions, not as the end point for answers!

Between a reel and reality stands knowledge—applied with responsibility!
