Electromagnetic fields (EMFs) are a combination of both electric and magnetic fields that travel in waves. They come from natural and man-made sources. The most familiar form of electromagnetic radiation is sunshine, consisting primarily of infrared, visible, and ultraviolet light.
Higher frequencies of electromagnetic radiation include x-rays and gamma rays, which are forms of ionizing radiation or radiation that can potentially destabilize molecules within cells leading to tissue damage. Exposure to large amounts of this type of radiation may be dangerous and has been linked to certain health conditions.
Lower-frequency electromagnetic radiation is emitted from many commonly used electronic devices such as cellular phones, computers, and microwave ovens.
While high-level sources of radiation are certainly a big concern, they are more easily avoided and we typically don’t encounter them as frequently in our daily lives. Low-level radiation sources, however, are constantly penetrating our bodies as long as we are in the general vicinity of electricity. The concern is that although they emit lower levels of radiation, extended exposure to these low-EMF sources may eventually lead to significant health issues over time.
