the neo health 9000 generates high voltage potential difference to make an indirect effect on a human body. in other words, a thick negative ion layer is made around the human body, and this reaction uses minerals in blood to prevent acidification and maintain alkalinity of blood, helping prevention of all kinds of diseases. the driving force of human life is biological electricity contained in a human body. the biological electricity of the cells in a human body controls the daily activities such as thinking, talking, moving, digesting foods, and coping with diseases. this biological electricity, however, decreases with the age of a person. in particular, irregular life styles of modern people, a variety of pollutants and stress, and acidified foods further weaken the biological electricity. the reduction of biological electricity lowers the activity of cells, accordingly resulting in weaker immunity. neo health 9000 applies the electric field to your body, helping you enjoy healthier life. beijing daxiang new material and technology co.
