Foot soaks can be a wonderful way to relax after a hard day or to help revive circulation in the feet. They may also be beneficial if you’re experiencing athlete’s foot. But can you detox your whole body through your feet?
While there is no scientific evidence to support the claims made by the people who profit from these detox baths, there have also been no reports that they are harmful. No foot detox method will flush toxins from your feet, but soaking them is a simple, harmless way to relieve stress.
The treatment is simple — you put your feet in warm salt water for 30 minutes with an electronic device spas call an array. Almost immediately, the water starts turning brown. After the end of the procedure, the water is dark brown and filled with metal flakes. Many spas claim to be able to tell you which area of the body has been detoxed by the color of the water. The color change is a simple matter of chemicals reacting.
When introduced to salt water, a chemical process called electrolysis takes place and causes the electrodes to rust at an extremely rapid rate. The color change will happen whether your feet are in the water or not.
There are benefits to foot soaks, but removing toxins from your body is not one of them. According to Dr. Stephen Barrett, M.D. the device cannot possibly draw toxins through the feet.
