Is Personality a Lie? The Internal Transmitters That Rule Your Life

Introduction: Late-night ramen isn't because you have a weak will

Hello, I'm Papazo.
Even though you swore, 'Tomorrow I'll wake up early and go for a walk!', the next morning you lose completely to the gravity of your futon.

Or, while slurping down a cup of instant noodles you grabbed at a convenience store late at night thinking, 'Just this once...', you fall into intense self-loathing.

Oh, this isn't Papazo's daily life...
I declare.
It's not a problem with your personality or a lack of willpower that causes this.

It might be a disturbance in your 'internal cocktail balance'!

The world says that 'success is born from a strong will,' but there is a greater presence within your body that your will cannot resist.

Our emotions, concentration, appetite, and even the moments we feel 'happy'—the ones holding the rudder of our lives are not the commands of the brain, but trace chemical substances flowing through our blood—'hormones'.

By the time you finish reading this article, you should stop blaming yourself and start feeling affection for your body as a 'precision machine to be mastered.'

Now, let's expose the identity of the unknown 'true rulers' that work 24 hours a day without rest inside your body.

Chapter 1: The 'Hidden Ultra-High-Speed Network' That Bypasses the Brain

We think of 'nerves' as the main system for information transmission in the body, but in the history of life, hormones are overwhelmingly older and more powerful 'seniors'.

1.1 Nerves as 'Fiber Optics' and Hormones as 'National Broadcasts'

If nerve transmission is 'fiber optics' that send signals to specific locations instantly, hormones are a 'national radio broadcast' that releases messages into the river of blood.

There is a time lag of a few seconds to a few minutes before they arrive, but once released, they influence all cells in the body simultaneously and continuously.

When you feel 'I'm just not in the mood today,' it might be that your internal broadcasting station is continuously sending a 'stagnation mode' signal to all your cells.

1.2 The Precision Puzzle Created by 'Locks and Keys'

Hormones travel throughout the body via the blood, but they don't act on just any cell at will.

For each hormone, there exists a specific keyhole called a 'receptor'.

The moment this 'key and keyhole' match, the cell's switch turns on.

Because of this mechanism, a tiny amount of substance can pinpoint and cause massive changes in life activity.

1.3 Even Plants Without Brains Communicate via Hormones

Surprisingly, plants that do not have brains also use hormones (plant hormones) to control their growth and flowering.

In other words, hormones are the 'basic system for life to live' itself.

One can view the phenomenon we call the 'mind' as the accumulation of the habits of these ancient chemical reactions.

Chapter 2: The Miracle of 'An Ear-Pick's Worth' in a 50m Pool

The most important thing in understanding the world of hormones is to know the gap between their 'overwhelming scarcity' and their 'enormous influence'.

2.1 The Unimaginable Control of "Trace Amounts"

Can you imagine how much hormone is contained in your blood?

To put it in perspective, the concentration is like "dissolving a single ear-pick's worth (about 0.1g) of a substance into a 50-meter swimming pool full of water."

This trace amount, which is difficult even to measure, is the source that makes you grow taller, increases your pulse, and sometimes squeezes out the "motivation" that can change your life.

2.2 The "Automatic Brake" Known as Feedback

Hormones are not just released indefinitely.

For example, when a certain hormone increases too much, the hypothalamus in the brain detects that "it is enough" and issues a command to stop secretion.

This precise feedback loop is the true nature of the "autopilot system (homeostasis)" that allows us to maintain our health without even being aware of it.

2.3 Latest Science: The "Full-Body Orchestra" Played by 32 Organs

A 2026 study (Molecular Cell journal) analyzed how 32 organs throughout the body precisely change hormones and proteins in sync with the rhythm of the body's internal clock.

Even while you are sleeping, your body is carrying out a "massive project" where over 10,000 types of messenger substances coordinate to prepare your performance for tomorrow.

Chapter 3: The "Three Main Managers" That Run the Body

Here, I will introduce the representative hormones that support your life from behind the scenes. Pay special attention to the "happiness-related" members that influence our moods.

3.1 Insulin: The Gatekeeper of Metabolism and Energy

This is the only hero from the pancreas that lowers blood sugar levels.

It plays the role of converting the food you eat into energy and delivering it to your cells.

Modern people overwork it (by consuming too many carbohydrates), and the beginning of diabetes is when it goes on strike, saying "I can't take it anymore!"

How you let it rest is the key to anti-aging.

3.2 Adrenaline and Cortisol: The Alarm for Crisis and Awakening

Adrenaline is what flips the "fight or flight" switch.

Cortisol, known as the "stress hormone," provides long-term support for this.

Both are essential for survival, but in today's high-stress society, they keep the alarm ringing 24 hours a day, leaving our minds as exhausted as a scorched wasteland.

3.3 The "Three Musketeers of Happiness" That Color Our Minds

Although this is a topic for next time, we cannot leave out the representative "happiness-related" ones.

* Serotonin: The "conductor" that governs mental stability. It is secreted when exposed to sunlight and suppresses emotional outbursts.

* Oxytocin: The "bonding substance" released when interacting with others. It is a magical liquid that erases anxiety.

* Dopamine: The source of "pleasure" and "motivation." It is maximized when something is achieved.

A state where these three are in balance is the physical reality of what we call "happiness."

Conclusion: You Can Become the "Great Manager" of Your Own Body

We are not "dictators" who can manipulate our bodies at will.

Rather, we are more like "managers" overseeing over 100 unique employees (hormones).

If you force them to work overtime, a strike (illness or depression) will occur.

Conversely, if you create an environment where they can work easily, your life will begin to change in surprisingly light and happiness-filled ways.

By becoming aware of the "invisible threads" called hormones, the way you see the world should change starting today.

Things You Can Do Starting Today: Try Giving Your Emotions "Hormone Names"

When you feel irritated, try saying, "Oh, adrenaline is sounding the alarm," or when you want to be kind to someone, "Oxytocin is circulating," and call your emotions by the names of these substances.

Just by doing this, a "calm distance" will be created between your brain and body, and you will realize that you are no longer being swayed by your emotions.

Now, at this very moment, which hormone is taking the lead in your body?
