What Are Negative Ions and How Do They Promote Health?

Himalayan salt lamps have a beautiful light that can improve mental health. There are people who claim that the negative ions emanated from these lamps boosts serotonin levels, improves mood, alertness, and depression.

There are hundreds of scientific papers written about this concept, some of which go back a century.

The idea behind negative ion therapy is basic: Positive ions in the air make people feel bad, negative ions in the air make people feel good. Half of this is true. Negative ions are in the air.

Some of the negative ions are generated by cosmic rays that slam into the atmosphere and spread their energy into molecules. Others are created through natural radioactivity, are emanated from the earth, or lightning bolts exploding negative ions in the sky. Even waterfalls and waves contribute to the negative ions in the air.

This is why people feel good when they are at the beach or after a thunderstorm: Negative ions. Scientists have been looking into this phenomenon for almost 100 years.

One study treated patients with seasonal affective disorder with different concentrations of negative ions. Researchers wanted to know if negative ion therapy worked better than bright-light therapy. The high concentration of negative ions worked just like bright-light therapy in reducing the patient’s depressive effects.

Another study was conducted that determined people who received a high concentration of negative ions had faster reactions times and were more energetic. When the negative ions are traded for positive ions, the opposite is true. Patients reported increased anxiety after two hours of exposure to positive ions.

Water molecules are supposed to land on the surface of the Himalayan salt lamps, liberating negative chloride ions from the lattice. However, that would require more energy than a salt lamp could generate. There are crystals and other tools that can increase the number of negative ions in the air. They can be expensive.

What Are Negative Ions?

As already indicated, negative ions are beneficial for the human body, and positive ions are harmful. Ions are invisible charged particles in the air – molecules that bear an electrical charge. The air contains negative and positively charged ions. Positively charged ions are molecules that have lost one or more electrons. Negatively charged ions, however, are molecules that have gained negatively charged electrons. Negative ions are abundant in nature. They can be found near waterfalls, on the ocean surf, at the beach, and after thunderstorms. Additionally, they are found in the mountain regions and in forests.

Negative ions are in the human body and the air breathed. They can contribute to overall well-being and health.

Negative ions have been scientifically proven to:

  • Neutralize free radicals;
  • revitalize cell metabolism;
  • enhance immune function;
  • purify the blood;
  • balance the autonomic nervous system, promoting deep sleep and healthy digestion.

Polluted cities, offices, industrial areas, schools, and cars hold the highest concentration of positive ions that are unhealthy for the human body.

One of the most important benefits of negatively charged ions is that they eliminate airborne allergens such as pollen, mold spores, bacteria, and viruses. They also clean the air and make it free of dust, pet dander, and cigarette smoke. Negative ions do this by attaching themselves to large numbers of positively charged particles and negatively charging those particles. As a result, viruses, bacteria, and pollen spores become too heavy to stay in the air and thus prevented from entering one’s breathing passage to make one sick. Negative ions provide a protective circle around people.

How to Create More Negative Ions in the Air

Negative ion air purifiers help people breathe cleaner, healthier air and protect people from exposure to allergens and viruses. Negative ion air purifiers keep away viruses, dust mites, and other pollutants that can make people sick.

People can purchase personal high-performance negative ion air purifiers to wear around the neck. The advanced ionic technology emits a constant stream of negative ions that force airborne pollutants away from personal space to create an area of cleaner, healthier air.
