Ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving the atom a positive or negative electrical charge. There are both positive and negative ions in the air, with positive ions usually carbon dioxide molecules that have lost one electron, while the negative – the oxygen molecule that has acquired an electron. Negative ions in the air attract particles of pollution, giving them a negative charge, as they are already heading to the ground. Mold, bacteria and allergens often carry a positive charge, and they can also be neutralized by negative ions. Obviously, it is desirable to be surrounded by negative ions as a natural way to protect our health.
The ions can not be produced without a source of energy – heat or flame, radioactivity, friction, evaporation, etc. They are the result of high-energy processes such as open flame or incandescent objects. When the water evaporates, negative ions are produced in the air, and as a result, the positive charges remain in the water that has not yet evaporated.
Nature is constantly creating negative ions to combat air pollution. That’s why the air is so refreshing after a storm – lightning produces a high concentration of negative ions that cleanse the air and make it so refreshing. Water from the waterfall also produces negative ions. The vast amount of negative ions in the clean air on the seashore is due to the constant flow of water at tides. Places like waterfalls and beaches where negative ions are naturally produced may have a negative ion concentration of up to 10,000 negative ions per cubic centimeter, while in busy cities this concentration reaches 100 ions per cubic centimeter.
Generally speaking, negative ions increase the oxygen flow to the brain, resulting in increased alertness, reduced sleepiness and increased energy. They can also protect us from microbes in the air, reducing irritation as a result of inhalation of different particles, which Make us sneeze, cough or cause inflammation of the throat. For the incredible one in three that are sensitive to the above, negative Himalayan salt ions can create a sense of fresh air during the morning walk, the refreshing moment in which we open the window and breathe in a cleaner, wetter air.
