The human body was designed in a way that it will be able to naturally fight infections and prevent diseases. It has ways of removing toxic substances like when you sneeze, when you cough, when you sweat, when you pee and when you remove bowels. Because of these you are usually able to stay healthy even if you take in toxic substances when you drink, eat, use health and beauty products and breathe. However, like any machine, the human body can also sometimes fail to do its functions well. There are instances when the body is not able to remove all toxins that are needed to be removed. When this happens, toxins accumulate. They get reabsorbed into the bloodstream and cause different health problems.
