Today, consumers are aware of the various health issues caused by over exposure to electromagnetic fields (EMF), a natural product of electronic devices commonly found in at home and in public places. This has raised concern in the medical community about the need for EMF Blockers that can help protect humans from EMF waves. The invisible waves are in our environment and have the ability to pass through living things, including humans. Some related health issues include tension headaches, skin rashes, heart palpitations, ringing in the ears, daytime fatigue, cognitive decline and sleeplessness. Dr. Andrew Weil, M.D., author of numerous health and wellness publications, has described EMF as “the most significant form of pollution human activity produced in this century, all the more dangerous because it is invisible and insensible." Concerned consumers are using EMF protection devices, such as the EMF Blocker products manufactured by Vortex BioShield, to guard against these critical health issues. The blockers come in various formats. They can be worn as jewelry, attached to electronic devices or even on a pet’s collar. Most are so small that they are hardly noticeable, but they will work 24/7. No batteries or chargers are required to maintain a blocker.
