	Katia Costa posted an update 3 days ago (edited) Energy: The Silent Definition of LifeFor the past 15 years, I’ve been translating medical research and books, a second job that slowly 
 became a window into something far greater than medicine itself.After so many years immersed in descriptions of the body’s functions, mechanisms, and diseases, I began to notice something beyond the text: an unseen pattern, a constant hum of energy that defines everything we are. - Each particle in our body (every atom, every molecule) requires energy simply to hold its structure. Without that continuous energy flow, matter itself would collapse. Our bodies exist because energy defines the boundaries of each cell, keeping form from dissolving into formlessness.
- Every process in our bodies (every cell dividing, every neuron firing, every breath drawn) relies on delicate exchanges of energy. Tiny, invisible particles move in and out of balance, maintaining the fragile gaps that make survival possible. And it’s in those gaps, those invisible spaces between matter and motion, that life truly exists.
 ❗Conclusion: we are alive because energy still moves through us, connecting the visible and the unseen. 💥The quiet presence of energy defining everything we are, and the realization that being alive right now is not just a biological fact… we are an energetic miracle. 
 If we pause for a moment and sense our pulse, our breath, or even our thoughts, we might feel it too.
 We don’t need to see or believe in energy. We are energy!➡️Going deeper (nerd talks 😁) – How Electrical Signals Travel in the Body Every thought, movement, or feeling (from happiness to pain) starts as an electrical signal. But this electricity isn’t like the one in wires; it’s generated by chemical elements constantly exchanging charges within our cells. 1. The Neuron: A Living Electrical Conductor Our body’s communication network is made of neurons, specialized cells that transmit information through electrical impulses. Each neuron has a membrane that separates two environments: - The inside, rich in potassium (K⁺) ions.
- The outside, rich in sodium (Na⁺) ions.
 This difference creates an electrical potential, like a tiny battery charged at about –70 millivolts. 2. The Spark of Energy: Action Potential When a signal (a stimulus, thought, or neurotransmitter) arrives, specific ion channels open. - Sodium ions rush into the cell, changing the charge from negative to positive.
- This triggers a wave of depolarization, an electrical pulse that races along the neuron’s length.
 This traveling pulse is called an action potential: the fundamental unit of communication in the nervous system. 3. Chemical Messengers Bridge the Gap At the end of one neuron lies a tiny space: the synaptic cleft. The electrical pulse can’t jump directly across, so the signal transforms into chemistry. - The neuron releases neurotransmitters (such as dopamine, serotonin, acetylcholine).
- These chemicals drift across the gap and bind to receptors on the next neuron or target organ.
- This triggers another electrical signal or a physiological response, like a heartbeat, muscle movement, or emotional reaction.
 🌟The Energy Behind It All This entire system depends on energy in the form of ATP (adenosine triphosphate). Every exchange of sodium and potassium ions uses molecular “pumps” that consume ATP. Without this constant energy flow, the electrical system collapses and life, as we know it, ceases. So even at rest, our body is a living field of energy and chemistry, with billions of electrical sparks flashing every second. When we think, move, or feel happiness, it’s not just happening “in our head.” 
 It’s the symphony of atoms, ions, and molecules orchestrated by pure energy.💥We are, quite literally, charged beings.
