Did you know that the human heart is the organ that generates the strongest electromagnetic field of any organ of the human body? In fact, the electromagnetic field of your heart can be measured up to a few feet away from your body. Furthermore, this energy field changes in relation to your emotions. One thing you should know about electromagnetic field is that every organ and cell in your body generate an energy field.
Because the heart generates the strongest electromagnetic field, the information stored in its electromagnetic field affects every organ and cell in your body. Could this be why the heart is the first organ to function in a fetus? Besides generating the strongest electromagnetic field, the heart has an intelligence of its own, which is why certain neurocardiologists refer to it as the heart-brain or the fifth brain.
