The bad news is that they say negative ions are good and positive ions are not. Air ionizers such as those used in static control emit both positive and negative ions.
Some experts say that our modern homes and offices seal out negative ions.
They also state that computer terminals, fluorescent lighting, forced air ventilation systems, and modern building materials generate an over abundance of positive ions. According to some experts, balancing the ionization in your workplace and home may help combat the ill feelings associated with stressful lifestyles. The world's most tranquil and refreshing regions are loaded with billions of negative ions. Air near waterfalls, mountains, beaches and forests are among those places where ionization levels are in complete and natural balance. After a lightning storm, most of us feel invigorated and refreshed.
