Electromagnetic fields are present everywhere in our environment but are invisible to the human eye. Yet they are a physical phenomenon, measurable with observable effects. EMFs come from a wide range of sources and vary enormously in the strength of the fields. Some are naturally occurring and others are the results of human activity for a better life.
The body’s own internal magnetic fields are generated by the extraordinary amount of internal electrical activity that keeps our bodies alive. These biomagnetic fields interact with all of the other magnetic fields on the planet and control our basic chemistry.
The human body produces complex electrical activity in several different types of cells, including neurons, endocrine, and muscle cells – all called “excitable cells”. As all electricity does, this activity also creates a magnetic field.
Nerve impulses are electrical energy signals; and, they create energy-fields around the body and electro-magnetic energy waves that can travel away from the body.
“The heart generates the largest electromagnetic field in the body. The electrical field as measured in an electrocardiogram (ECG) is about 60 times greater in amplitude than the brain waves recorded in an electroencephalogram (EEG).”
The human heart is a powerful source of electro-magnetism that, even at a few meters away, is detectable by modern scientific instruments. The heart emits an electromagnetic field that changes according to our feelings. So external levels of the electromagnetic field can disturb in the body’s internal electromagnetic fields and cause damage in biological tissues and organs even in lower levels of acceptable exposure limit based on regulatory authorities’ rules.
