The "junk" and the funky colors in ionic foot baths are primarily the result of a normal electrochemical reaction (rusting) of the machine's metal parts, not toxins being pulled from your body. The process happens whether feet are in the water or not. [1, 2, 3]
The Science Behind the Color
Here is a breakdown of what actually causes the water to change color:
- Electrolysis and Corrosion: The machine works by running a low-voltage electrical current through the salt water via an "array" (an electrode made of metal, often stainless steel). This process, called electrolysis, causes the metal in the array to corrode or rust very quickly, releasing metal ions (like iron oxide) into the water.
- Water Composition: The natural mineral content and impurities in the tap water itself (e.g., iron, calcium, chlorine) react with the electrodes and the salt, which contributes significantly to the color changes and residue.
- Salt: Salt is added to increase the water's conductivity and allows the reactions to occur.
- Presence of Feet: When feet are submerged, the oils from the skin, dead skin cells, and a user's unique acid/alkaline balance can slightly alter the appearance and texture of the residue, making it a bit stickier than water-based residue. [2, 3, 4, 5, 6, 7]
Scientific Evidence
Multiple studies and investigations have debunked the claim that the colors represent bodily toxins.
- Experiments without feet: Researchers have demonstrated that the water turns the same murky brown color even when the machine runs without any feet in the basin.
- Lab analysis: Water samples analyzed after sessions primarily showed high levels of iron (rust) and no detectable amounts of common bodily waste products like urea or creatinine.
- Urine and hair samples: A study published in the Journal of Environmental and Public Health tested participants' hair and urine samples before and after a series of ionic foot baths and found no change in toxin levels in their bodies. [2, 3, 8]
In summary, the color change is a visual spectacle resulting from a basic chemistry experiment, not evidence of detoxification. Your body has efficient natural systems (liver and kidneys) for filtering and eliminating actual toxins. [1, 2, 9]
