Negative ions are odorless, tasteless, and invisible molecules that we inhale in abundance in certain environments. Think mountains, waterfalls, and beaches. Once they reach our bloodstream, negative ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress, and boost our daytime energy.
Far infrared mats using amethyst and tourmaline crystals generate heat and negative ions that safely permeate the body. Increasing the amount of negative ions is necessary to nullify the effects of positive ions. These negative ions generate a boost to the immune system.
Enhancing immunity has a major concern to modern healthcare. The best way to protect ourselves from diseases should be to focus on how we can improve our own health and not how advanced the current medical technologies and research are.
