Experiencing headache, uneasiness or sudden nausea in an overcrowded room is a common problem. Sometimes even in an air-conditioned room you might experience these problems. Reason?

 Lack of negative ions in the room.Don’t go by the name, there is nothing negative or unhealthy about negative ions. Negative ions are beneficial for the human body while positive ions are harmful. In fact, you will find the highest concentrations of negative ions in natural, clean air. Ions are invisible charged particles in the air – either molecules or atoms, which bear an electric charge.Negative ions are abundant in nature, especially around waterfalls, on the ocean surf, at the beach and after a storm. They are widespread in mountains and forests.Negative ions are present in the air we breathe in and they are also present in our bodies. The degree to which negative ions contribute to overall well-being and health is scientifically proven: 

 * They neutralize free radicals. 

* They revitalize cell metabolism.

 * They enhance immune function. 

* They purify the blood. 

* They balance the autonomic nervous system, promoting deep sleep and healthy digestion.(Source: kiflow.com)

-Negative ions increase your sense of well-being and mental clarity by removing the debilitating effects of excessive positive ions in your environment. They are often described as a natural anti-depressant. 

-Negative ionizers are proven to clear the air of dust, pollen, pet dander, mold spores and other potential allergens. 

-A good negative ion generator can significantly decrease airborne viruses and bacteria in your home. 

-Improves the function of the cilia in your respiratory tract that protect your lungs from irritation and inflammation, thus leading to less instances of respiratory illnesses like colds and flu and even hay fever and asthma. 

-Negative ionizers have a relaxing effect and have been reported to normalize your breathing rate, decrease blood pressure and relieve tension. 

-Because negative ions are absorbed directly into the bloodstream they may help to combat harmful free radicals within your body. 

-Improved energy levels and focus. Research at the University of California showed negative ions normalize serotonin levels in the brain, potentially improving a person’s positive outlook and mood. 

-Better sleep. A French study found using negative ionizers could help you to sleep better. This is once again due to their positive effects in normalizing serotonin production in the brain. 

-Reduces instances of headaches and sickness. The company Norwich Union found installing negative ion air cleaners in a work area full computers and other electronic equipment reduced instances of reported sickness and headaches by 78%. 

- Negative ion generators are also routinely used in hospitals in Europe for their beneficial impact on patient’s health and healing rates. 

-Elevated mental concentration and performance. Testing has regularly shown that subjects exposed to high levels of negative ions perform better in mentally challenging tasks than those breathing normal positive ion dense air. Pierce J. Howard PhD at the Center for Applied Cognitive Sciences says in the Owners Manual for the Brain – “Negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy.”
