Negative ions are tasteless and odorless molecules found in the air. They are known to increase oxygen flow to the brain and, as a result, facilitate alertness, decrease drowsiness and stimulate mental energy. Negative ions are also known to protect against germs and decrease throat irritation as well as sneezing and coughing.
Most particles found in the air are positive ions or have a positive charge. Negative ions are particles that are negatively charged. Negative ions are drawn to positive ions as a result of magnetic attraction. According to peakpureair.com, when negative ions are in high enough concentration, they attach themselves to floating air particles. This causes the floating particles to become heavy and drop out of the air.
Positive ions are released into the atmosphere by air conditioners, televisions, computers and other electronic devices. These ions are responsible for a variety of symptoms including headaches, fatigue, nausea, and dizziness. These symptoms originate from the fact that electronic devices deplete the air of negative ions. According to "The Owners Manual for the Brain: Everyday Applications from Mind Brain Research" by Pierce J. Howard, negative ions occur naturally as a result of air molecules breaking apart from sunlight and radiation as well as from the movement of air or water.
Locations of Negative Ions
High concentration of negative ions can be found in a variety of natural environments. These include forests, mountains, waterfalls and beaches. In nature, negative ions are generated by lightening, sunlight, ocean waves and falling water. According to peakpureair.com, Niagara Falls is one of the highest natural producers of negative ions in the world.
Salt as Therapy
Besides traveling to locations with high concentration of negative ions, a negative-ion rich environment can also be created in one's home. Natural salt therapy (in particular, Himalayan salt therapy) is highly recommended. Himalayan salt contains up to 84 minerals and trace elements and, according to springmountainnaturals.com, it should be used by individuals with chronic congestive problems in order to increase the amount of negative ions in the atmosphere. The salt comes in the form of salt candles and salt holders and have all of the benefits of mechanical ionizers.
Indoor waterfalls are another natural way to increase negative ions in the air. Waterfalls produce a disturbance of water molecules. This disturbance causes a displacement and breaking off of electrons. The spare electrons seek out oxygen molecules, giving the molecule an extra electron and therefore a negative charge. According to discountfountains.com, indoor fountains are a great way to achieve a beneficial result similar to the air around a waterfall.
