1. Did you not read the manufacturer's explanation of this device? If not, go to detox-online.org and click on "the truth". This is the manufacturer MARY STAGG's OWN WEBSITE, and you can purchase these ridiculous machines right on the site. However, the FDA stepped in and required her to tell people the truth about the machines. It is a bit lengthy and may be difficult for some people to understand, but it clearly states that the standard sales pitch is a total lie. READ THE ENTIRE MESSAGE, not just the end. She throws in some bogusness about "bio-stimulation" (a made-up word by the alt-med crowd which has no proven scientific validity) at the end, but any learned person can see right through that. When you do your "self tests", of course the results will be different in the machine with no feet in it, because the feet introduce certain impurities which will alter the chemistry in the water. However, it would be interesting to see what your reaction is when all of your other tests (blood Sugar + pressure, etc.) come out the same.
2. A very quick google search would have allowed you to discover what really causes car sickness. It has nothing to do with ions or static. Car sickness is a form of motion sickness, which some people experience riding in automobiles, airplanes, boats, trains, and amusement rides. The discord among signals the brain is receiving from the body causes nausea and feelings of discomfort.
Your brain gets information from several sources concerning the type and direction of your movements. The first, and most important, source is the inner ear. The inner ear, also responsible for balance, contains fluid that shifts according to your body's movement, pushing little hairs one way or the other. This lets your brain know about the direction you're moving in. Your brain also receives information from the eyes, skin pressure receptors that tell the brain what parts of the body are on the ground, and muscle and joint receptors that tell the brain which parts of the body are moving. The central nervous system (the brain and the spinal cord) compiles all of this information to create a complete picture of what is happening.
If signals don't make sense together, you may experience motion sickness. For example, say you are reading a book in a car. Your inner ear and skin receptors are telling your brain that you are moving. Your eyes see only the stationary book, and tell your brain that you are not moving. These bits of information don't go together, and the result is the discomfort that you feel and call car sickness.
Symptoms of motion sickness include unease and headaches in mild cases, to nausea, vomiting, excessive sweating and salivation, and dizziness, as well as feelings of anxiety and loss of color in the face in more severe cases.
I swear, it's as if you alternative medicine people had never picked up a legitimate book in your entire lives. Please, GET AN EDUCATION. It is very disconcerting to those of us in the real world to see so much insanity on a daily basis. Thank you.
