Laptops, tablets, cell phones and similar devices emit electromagnetic fields (EMF), invisible waves that can pass through a human body. People of all ages use these electronics daily; however, the medical profession warns that EMF exposure over a long period of time can cause high blood pressure, sleeplessness and severe headaches. Some suspect that EMF may lead to cancer. Curtailing cell phone use is a way to protect limit EMF, but most people find that suggestion impossible. A better solution is an EMF protection device from Vortex BioShield when using electronics. The most convenient is the EMF protection necklace, which can be worn around the neck or carried in a pocket. The necklace is made of high-quality materials and comes in several traditional styles. Like other EMF protection devices the company produces, each necklace contains powerful crystals that help defuse unseen EMF waves. The attractive bioshield necklace is just one value-priced protector from Vortex BioShield. Each device is ideal for combating the threat of EMF over exposure, yet none will interfere with the performance of your electronic devices.
