Invented in 1986, the TESLAR technology was designed to emit a unique signal that strengthens the bodys own electromagnetic energy field and helps reinforce the bodys energy field to better resist the potential negative effects of external, low-energy electromagnetic fields (EMF) given off by cell-phone systems, computers and many other electronic devices. As a result of the TESLAR effect, past wearers have experienced : deeper, more restful sleep; more calm and less tension; improved concentration; increased levels of energy; an overall improvement in well-being.
