Hei, jeg har også følt meg som deg. Jeg dro og tok detox-fotbad, jeg skal love deg at det kom mye dritt ut!!! (unnskyld språket)

Her har du en forklaring på hvorfor vannet blir grumsete, det har ingenting å gjøre med detoxing.... (jada, jeg vet at jeg er en party-pooper nå ):

En konsis, men mer detaljert forklaring på hva som skjer, finner man blant annet her:

You place your feet in a bowl of water to which a bit of salt has been added. A small electric current is passed between two electrodes immersed in the water, which soon becomes quite discolored. The color, of course, comes from electrolytic corrosion of the metal electrodes. These are usually made of iron, nickel, and copper, all of which decompose into colored ions. These colors will vary with the amount of salt present and the pH of the solution, and they can be changed and greatly intensified by the substances that either added to the bath before use, or are present in the “soaps” often used to prepare the patient’s feet. By-products of the electrolysis process are bubbles of hydrogen and chlorine gases (both of which are dangerous in confined spaces) and sodium hydroxide, commonly known as “lye”. The latter tends to soften skin, allowing it to flake off, pick up various colors on reacting with the metal ions, and complete the illusion that one usually pays dearly for.

Det er mulig slike “avgiftende” fotbad kan være avslappende, men det de trekker ut, er ikke “gifter”: “all that really gets cleaned out is your wallet!”
