Water Filters & TechnologiesWhy Water Needs Light — and what this has to do with your health
There is water that makes you tired after drinking it — and water that invigorates you. The difference lies not only in mineral composition, but possibly also in the light content of the water. What the research of Prof. Gurvič says about this.
💡 Key facts
- Living organisms — including water — interact with light (photons). Biophoton research investigates this interaction.
- Fresh spring water that has experienced sun and movement differs in its formation from water in long, dark pipes.
- Measurable and immediately applicable: water quality by Vincent criteria (conductivity, pH). That is the foundation.
- Everything beyond — light energy, water memory — belongs to a fascinating, still-open field of research.
📖 Key terms briefly explained
1. An observation everyone has made
Imagine hiking in the high mountains and coming across a mountain lake. You kneel down, scoop water with your hand and drink. Something remarkable happens: this water doesn't just taste fresh — you feel refreshed, invigorated. Different from the water at home from the tap. What is going on? The biophoton research field investigates exactly this question.
🔍 An honest word upfront: This topic touches a frontier area of science. Some aspects are well documented, others are still being researched, some are disputed. We describe what the research shows — and clearly mark what remains open.
2. What photons are — simply explained
When you open the window in the morning and the sun shines on your face, you feel warmth on your skin. What you don't see: in every ray of sunshine travel countless tiny energy particles — photons (from Greek "phos" = light). A photon is the smallest possible unit of light. It has no mass, moves at the speed of light and carries energy within it. Albert Einstein received the Nobel Prize in 1921 for his explanation of how photons interact with matter — the so-called photoelectric effect. This is not fringe science, this is established physics.
3. Why all life needs light
Plants are the most obvious example: photosynthesis converts light energy into chemical energy — without light, no growth, no life. But animals and humans are also dependent on light: it controls our sleep-wake cycle, hormone release, and vitamin D production.
4. Water as a light store — what Prof. Gurvič observed
In the early 20th century, Russian biologist Prof. Alexander Gurvič (1874–1954) made a surprising observation: growing plant roots seemed to stimulate each other — even without direct contact, only through a glass partition. He concluded that cells emit ultra-weak light impulses — which he called mitogenetic radiation, today known as biophotons.
In Germany, Prof. Fritz-Albert Popp (1938–2018) continued this research. He was able to measure that living organisms do indeed emit light — in extremely weak but measurable amounts. His thesis: biophotons might play a role in cell communication. This has not been proven in the strict sense — but it is measurable.
🔭 What research shows — and what remains open
✓ Documented
- Cells emit measurable light impulses
- Plants respond to light in complex ways
- Water absorbs energy from its environment
? Still open
- Exact role of biophotons in the body
- Whether water can store light energy
- How long such an effect lasts
5. The practical conclusion: what you can do now
Regardless of all open questions about biophotons: what is measurable and actionable today are the three Vincent parameters. Water that scores well here — low conductivity, slightly acidic pH, low redox — is the closest thing to what nature produces in a mountain spring.
EIGW recommendation: Start with what is measurable. The Trink Dich Fit water station is based on EIGW measurements, optimises all three Vincent parameters simultaneously. As a natural reference: Plose, Lauretana, Voss.
