The bath soak in the Hot water with the Epsom Salt and Baking soda is for the purpose of pulling the Acids and Toxins out of your body!
It may work better if you also use the Hydrogen peroxide in the water, for this may help neutralize more of the Acids which are pulled out!
What happens is that the stored Fatty Acids may become Released into the Lymphatic system for removal thru the skin pores!
But this means that when you stop soaking that your Lymphatic sysetm may become overloaded with these Toxins, if you have a lot of them stored in your body!
This is one of the reasons why I made the suggestion to take it slow at first in the length of soak time , if you are sick or have a lot of stored Fatty Acids!
Now the other very important suggestion which I made was for the person to take a "COLD" shower immediately after the Hot soak , so as to Reverse the Nitrogen Isotope in the body, which may be now of the Acidic form because of the Hot water, to the Isotope of Alkaline Nitrogen by the action of the "COLD" water!
And by taking this cold shower you may feel much better , than if you do not do it this way!
The whole process is dealing with the removal of your stored Fatty Acids and if they are not completely released from your Lymphatic system, then you may feel Bad!
But if you do the process correctly , as time goes on and you are able to rid your body of the excess stored Fatty Acids, then you may feel a lot better!
Smile Tis your choice.
