I recently spent three days experiencing the alkaline baths, and I cannot recommend them highly enough. I noticed a truly remarkable improvement in both my physical and mental well-being. I felt deeply rested and completely renewed. My muscles …

Where to read up
Experiential knowledge. Labelled and written down.
Here you’ll find what we know about long alkaline bathing — and how we know it. Anything measured is shown as a number. Anything that’s a model carries a stamp. Whatever people have experienced remains an individual case. Four doors: the basics, the blog, the voices, the recommendations.
Water, carbonates, time — that’s all there is to it. The knowledge behind it is on these pages.
Where to start
Three levers, one mechanism. Explained on one page.
The basics page is the short version of everything we go into in depth in the video and the courses: where acid comes from, what the skin has to do with it, why the water needs hours and where our claims end.
How it works
From acid to history — seven sections
- over-acidification as a model: 70/15/15
- the skin as the third kidney — an image
- bath osmosis: how we explain what we see
- the three levers: pH, temperature, time
- the phases 0–4–8–12 h
- the temperature pull: acid moves to where it’s coldest
- history: where the protocol comes from

You can measure all three values yourself: test strips, thermometer, clock. Everything else on this website is experience or a model — and labelled as such.
Where to read on
Alkaline topics. Four directions.
On the blog we regularly post about new topics — sorted by where you are as a reader, not by date: getting started, understanding the practice, planning Thailand or going deeper. Each topic ends with the path that suits it.

What people have experienced
Voices from the water. Individual cases, not proof.
Guests and course participants write about what they experienced — calm, clarity, sleep, skin. The rule: no incentives, no selection by results. What we don’t conclude from them is noted alongside on the Experiences page.

What you need
Carbonates, test strips, thermometer. All on one page.
The carbonates page explains choice and dosage — and what to look for when you buy.

In short
Five questions that almost everyone asks first.
Is alkaline bathing the same as a salt bath?
No. Salt — sea salt, Dead Sea salt, bath salts — is pH-neutral in water. Carbonates are what make the water alkaline: food-grade sodium, potassium, magnesium and calcium carbonate. Only that can be checked with a test strip. More on carbonates.
Why pH 9.5 — and not higher?
9.5 is the starting value we recommend, provided you’re not heavily over-acidified. If you’ve had a lot of medication, intensive medical treatment or substances over the years, you’re usually heavily over-acidified and start more carefully. The pH scale is logarithmic: each step is ten times the previous one. The course teaches you how to de-acidify faster with a higher pH and where to start in your case.
Do I really have to bathe for twelve hours?
No. Twelve hours is the long format at the bathhouse. At home, you build up in stages: 1 h, then 6 h, then 12 h — and if you don’t have a tub, you begin with a foot bath.
Is this medically proven?
We share experiential knowledge from more than 1,000 guided baths, not studies. Wherever we work with models — 70/15/15, osmosis, the phases — there’s a stamp next to it. An alkaline bath does not replace a medical diagnosis or treatment. What we can’t measure, we don’t claim.
I don’t have a bathtub. Where do I start?
With your feet. An alkaline foot bath needs a bowl, carbonates and 30–60 minutes. Read the article on foot baths.
