Although called negative, the negative ions possess a lot of positive health benefits and in general are capable of creating positive emotional states. Let us see first what the deffinition of positive and negative ions is.
Physics tells us that positive ions are atoms or molecules that have lost one or more electrons, therefore having shortage of electrons. Negative ions on the other hand have gained one or more additional electrons, which, because of the negative elemental charge of the electron, make the system negatively charged as a whole.
In nature we have a delicate balance between negative and positive ions. For example, during thunderstorms the natural ratio of positive vs negative ions in the air can be disturbed very easily. A couple of hours before the weather storm front hits the area, the concentration of positive ions in the air is very high. During the storm and following the storm, the number of positive ions gradually declines, while at the same time the concentration of negative ions is increased.
Research has shown that positive ionization present during wind storms leads to weather sensitivity in people, such as irritation, exhaustion and health problems.
In contrast to exposure to positive ionization, the surplus of negative ions is associated with mood improvements, resistance to stress, and better general health. Some studies suggest that negative ions are biologically active and have a positive impact on the natural 24-hours cycle.
It is generally accepted that negative ionization has a positive effect on stabilizing the blood pressure, improving the function of the cardiovascular system, increasing the alkaline environment of the organism, accelerating physical recovery, strengthening the bones and improving the respiratory and nervous system.
The balance of negative vs positive ions is usually disturbed in offices, factories, and shopping malls where we encounter an excess of positive ions. Residential areas, mountains, parks, beaches, forests and springs are places where we have high concentration of negative ions.
Waterfalls are especially beneficial, having one order of magnitude higher concentration of negative ions than positive ones.
Negative ions have been found to help eliminate pollen, dust, and similar agents from the air: all that we cannot see with naked eye.
The good thing about negative ions is that they are not harmful even if their concentration is very high.
In nature, as we have already mentioned, beneficial negative ionization is created after storms and lightning. Negative ions are also produced by the ionization action of cosmic rays, and by the activity of the chemical element radon present in the earth's crust.
In the ancient art of Feng Shui, negative ions are generated using indoor fountains.
Another natural source of negative ions is beeswax. When burned, beeswax gives off negative ions that purify the air and improve the mood. Beeswax candles are good sources of natural negative ions.
Natural salt is also believed to be source of negative ions.
Made from salt (NaCl) crystals from the Himalayan this salt lamp includes a 15-watt bulb, which gives an amber glow. Different bulbs may give different hues to the lighting area.
Although the salt lamps are somewhat controversial in their exact mechanism of ionization, there seems to be an overwhelming amount of testimonials about the usefulness of such crystal salt lamps. The functioning of the salt crystal lamp, obviously, cannot be compared directly to the mechanism of ion production in a typical ionizer. In addition, there are many beneficial properties that an ionizer does not have. For example, the color of the salt crystal can have a healing effect. The most common orange color facilitates a feeling of security, the yellow color encourages intellectual activity, while the red color is vitalizing and provides energy. Also, salt as a primal element of nature contains minerals and trace element that possess biological and biochemical activity.
There is a class of devices designed to give off a flux of negative ions. Some are better than the others, and there are brands capable of producing ozone in parallel with ions. Here is a review of one device we found especially convenient.
Tourmaline is a piezoelectric stone. This means that it can generate an electrical signal when pressure or strain is applied on the surface of the stone. In addition it is a pyroelectric stone, which means that temperature changes can also generate a weak electric current within the stone. Tourmaline also produces far infra-red radiation. All this is believed to be sufficient to convert moisture from the air to negative ions. Many believe that this natural and safe negative ion emission is the reason why Tourmaline is such a wondrous and beneficial stone.
Amethyst is another natural gemstone that is believed to offer similar health benefits to that of Tourmaline. The same argument - far infrared radiation - is stated for Amethyst.
Amethyst crystals are also believed to emit negative ions and can bring about similar benefits, including removal of toxic particles and free radicals, better respiration, and removing aerosol and dangerous chemical from the air.
While salt lamps do emit some negative charge, it is likely that the ion output is not too intense and that it doesn't extend too much from the surface of the lamp.
Tourmaline, Amethyst, and similar crystals are believed to be able to spread negative ions, but here the effect is even less pronounced than with salt lamps.
If you are looking for really strong levels of discharged negative ions, you have two practical options: first, enjoy the natural negative ions produced during and after a thunderstorm, and second, use a corona-discharge ionizer that gives you even stronger levels of discharged negative ions.
What materials other than stones give off negative ions?
I don't know about any synthetic materials. As already said, natural materials like crystals can be great sources of negative radiation. Ocean waves produce negative ions. There are also bubbling streams, waterfalls, pine trees and mountain tops which, obviously, all belong to the outside sources. Indoors, there are some plants, such as a maidenhair fern that you can use for that purpose.

Don't you guys think that even salt blocks used to make salt can be asource of negative ions?
sir i want negative ion circuit diagram and layout says:
I working on negative ion generator project so help me....
Lindy Lumbert says:
there are many people making natural generators now including: tensor rings, bamboo charcoal cloth, Teviron and Neoron fabric from Japan, a pile of Royal Oak charcoal on the ground, 1/4 cup of tiny copper coils mixed with Diatomaceous earth, copper coils wound in a clockwise direction split EMFs in the air and send negative ions out the clockwise side while sending positive ions out the back of it., some orgone or orgonite, pyramids of almost any material if made with the right geometry, as well as cones.
Himalayan Natural Crystal Salt Lamp does not generate negative ions, scientifically proven. www.youtube.com/watch?v=ZQ--scjcAZ4
By far, the best way to get negative ions/electrons is by standing barefoot outdoors on a natural surface like grass, sand or dirt. Grounding mats work well too. Shoes insulate us from making (electrical) contact to earth. This trend began in the 1920s and continues to today (chronic illnesses rampant). The addition of unnatural positive ions (wireless tech, radio, TV etc) makes it more difficult on our health. Read The Invisible Rainbow.
