Generally speaking, negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy," says Pierce J. Howard, PhD, author of The Owners Manual for the Brain: Everyday Applications from Mind Brain Research and director of research at the Center for Applied Cognitive Sciences in Charlotte, N.C.
"They also may protect against germs in the air, resulting in decreased irritation due to inhaling various particles that make you sneeze, cough, or have a throat irritation."
And for a whopping one in three of us who are sensitive to their effects, negative ions can make us feel like we are walking on air. You are one of them if you feel instantly refreshed the moment you open a window and breathe in fresh, humid air.
Places like waterfalls and beaches where negative ions are naturally produced can have a negative ion concentration of up to 10,000 negative ions per cubic centimeter whereas busy cities can have negative ion levels as low as 100 ions per cubic centimeter.
What we use…
It is possible to buy machines that create negative ions, but I've found that salt lamps are a less expensive and very effective alternative.
I use salt lamps often in our home, and especially in winter months when it isn't possible to have the windows open or to spend as much time outside. I love them for their ambient glow and their negative ions.priced at $26.50. $35.00 $43.00 and $53.00 in store as from 20/03/2015
