Use a Bio-Mat to release 600 to 1000 volts of static electricity into a room. The negative-ion particles released from the mat change the particles in the air. A layer of dust accumulates when these air particles fall. Inside the human body, calcium and sodium get ionized. The body becomes more alkaline.
Go to the beach or the mountains. The air circulating in these areas contain thousands of negative ions. Crashing waves and the scent of rain create negative ions and elevate moods, says Dr. Michael Terman, of Columbia University.
Use a negative-ion generator in the home or office setting. Dr. Terman says that these relieve depression as much as antidepressants, and have no side effects.
Take a hot shower. The steam releases negative ions into the atmosphere.
Practice feng shui. Feng shui uses indoor water fountains, which spray negative ions into the air. Ferns and other indoor plants release negative ions into the room.
