It sounds incredible, but it has been proven by scientific studies: Electric current can positively influence human well-being! The experiments on the healing effects of ion therapy date back to 1891, when the brilliant inventor and electrical engineer Nikola Tesla introduced the coil named after him for the wireless transmission of electrical energy. He demonstrated that he could conduct electricity through his own body without sustaining injuries. In fact, he even found that the energy boost promotes better sleep, lowers blood pressure, and alleviates allergies or respiratory diseases. Bestselling author and health expert Dr. Earl Mindell extensively discusses the effects of positive and negative ions on the human body in "The Happiness Effect." He particularly highlights the benefits.
