The Unnatural Normal

What Our Bodies Endure in an Overstimulating World

Our way of living has changed faster than our human biology can adapt. Many of us feel this in small but persistent ways: a low hum of stimulation, a sense of being slightly “on,” a nervous system working harder than it should just to stay balanced. Even when life looks manageable from the outside, the body speaks a different story.

Some people experience this as breath tightness or restless sleep. Others notice it as foggy thinking, irritability, low resilience or recurring minor illnesses. And many sense that something feels off, but they cannot pinpoint why.

These are not failures of health. They are signs of human biology struggling to maintain homeostasis in an environment shaped by technology and progress at the cost of human biological needs.

Not to mention the other systems woven into our lives, also creating stress responses. The ones that reach into our choices, our bodies and even our sense of what “normal” looks like. The beauty industrial complex is one of them. This post from ‘father_karine’ is a worthwhile read: interesting, confronting and enlightening, diving into how deeply we are influenced.

And I’m close to placing parts of the “wellness” world in the same category: another industry ready to capitalise on human physiology and insecurity. We are sold serenity as a product, as though calm is something to buy, rather than a biological state we return to naturally when life supports us.

Proceed with caution here. Anything that suggests you must be perpetually “calm,” constantly “positive,” or endlessly “centred” ignores the reality of a human nervous system. A healthy nervous system does not live in neutrality; it feels! It rises, responds, expresses and then returns to balance. Real regulation is not suppression. It is the natural rhythm of activation, emotions and feelings and restoration.

Information that honours this full biological cycle, not just the performative calm, is worth our attention. Wellness should support the body’s capacity to feel and recover, not instruct us to flatten our emotions for the sake of being easier to manage.

Back to the subject at hand; so how do we, and our bodies, make sense of an overstimulating world and understand how to support ourselves inside it? In practical ways, grounded and aligned with how human biology actually works.


The Modern Disconnect

What would life feel like if human advancement had unfolded in a way that still honoured nature, biology and wellbeing?

We celebrate our medical technologies, but I often wonder how many of these “advancements” would even be needed if our current environment supported the natural rhythms that our human biology depends on.

After a recent three-day sojourn away from the city, enjoying being barefoot on sand and grass, sunshine, sea swims and sleep aligned with the sunset, I started to feel like myself again. No traffic, no being woken by others in the night, no airplanes, my anxiety softened. My mind cleared and my body steadied. A sense of mental well-being returned. A kind of internal spaciousness I rarely feel in the city.
I thought I had a sleep issue. But my little rest reminded me that I do not.

The feeling lasted twenty-four hours after returning to the urban environment before the low hum set in again. The faint buzz of overstimulation. A sharp reminder that my system is responding to something constantly, even when I’m not aware of it.

Maybe this is just how city life feels. But when I step away, my whole system exhales. The static fades. I believe this state we accept as normal, the overstimulated state, is not normal.


Invisible Pressure: How Electromagnetism Triggers Stress

If, like me, you feel anxious when learning about the environment we live in, reading about the pervasiveness of EMFs and electromagnetism can feel overwhelming. It is confronting because it relates to the world we are all immersed in, every hour of the day, with no true way to step out of it. I had an abrupt awakening after reading The Invisible Rainbow - an incredible and eye-opening book. If you choose to read it, I highly recommend following it with EMF**D, which offers more practical solutions and ways to support yourself.

The purpose of the information I have found and outlined here is to help you understand why you might feel unsettled more often, even when you are living well.

Instead of assuming your lifestyle is the problem, it may be more accurate to recognise that our current environment places a steady load on the body that it was never designed to handle. It is constant enough to influence how we breathe, sleep and feel each day.

Electromagnetic fields, WiFi, Bluetooth, mobile signals, blue light and household electricity all interact with our human biology, which is shaped by nature and natural cycles. Human physiology evolved alongside sunrise and sunset, natural magnetism, open horizons, clean air, darkness at night, and long periods spent outdoors. Our cells rely on predictable cues from light, temperature and environmental rhythms.

The body’s internal electrical system runs on minerals like magnesium, potassium, sodium and calcium. These carry tiny charges that allow the heart to beat, nerves to signal and muscles to contract. When surrounded by modern frequencies at all hours, the body must continually adjust to inputs it was never meant to process.

Research suggests EMFs can increase oxidative stress inside cells, forcing mitochondria to work harder just to stay balanced. Other studies indicate electromagnetic fields can influence calcium channels on cell membranes, subtly increasing inflammation and electrical sensitivity. These effects accumulate quietly in the background and shape our overall sense of well-being.

Sleep is affected as well. Evening exposure to WiFi, blue light and electrical noise suppresses melatonin. Melatonin is not only a sleep hormone. It is one of our strongest antioxidants and a key driver of cellular repair. When sleep chemistry is disrupted, nighttime restoration becomes lighter, shorter and less effective.

I hope this resonates as information that is simply naming what many of us feel but have not had language for. The hum. The tension. The subtle sense of mental or physical fatigue. The sense that our bodies are working harder in the background, even when life seems manageable.

This is the reality of living in an environment that has changed faster than our biology can adapt. Understanding this is the first step toward supporting ourselves inside it.


The Biology of Wired and Tired

Sleep keeps teaching me the same lesson: if I’m on my laptop later in the day, I still fall asleep, but the sleep is wired. I wake too early, or I wake with that slight edge of overstimulation still humming in my system. When that happens, I always revert to Yoga Nidra, even at 3 am, because it gives me a sense of restoration that my night's sleep didn’t deliver. Wired and tired is the body signalling that it didn’t get the conditions it needed for its deepest repair.

One of those deep-repair systems is the glymphatic system - the brain’s overnight clearing cycle. It only switches on fully during strong, slow-wave deep sleep. In that phase, the brain literally shifts its architecture: brain cells shrink slightly, the fluid channels around them widen, and cerebrospinal fluid can move through the brain like a cleansing tide, clearing metabolic waste, excess hormones, inflammatory by-products, and the residue of digital stimulation. When we’re exposed to screens, bright light, or late mental activity, we don’t drop into that deep phase cleanly or stay there for long. The cleansing flow becomes reduced, patchy or cut short. You wake feeling as though the body never fully “reset.”

There’s another layer here that most people never learn about: the second cortisol wave. Humans have a small, natural cortisol lift later in the evening; a subtle fluctuation that evolved for nighttime alertness and survival. But in our tech-saturated, overstimulating environments, with bright screens and constant input, that gentle rise is amplified, pushing deep sleep away. What was once a quiet survival rhythm now shows up as the “second wind”: suddenly alert, slightly restless, mentally switched on. And once you’re in it, the body acts as though the day isn’t finished. When melatonin is suppressed or delayed by screens, WiFi and overstimulation, the sleep window shifts later, making sleep lighter and more fractured.
