Are Negative Ions Good For You?

I have been critical of salt lamps that are touted to create negative ions which some people claim have health benefits.  There is a problem with this idea, which is that free ions aren't necessarily a good thing.  They are inherently reactive, like putting bleach into the air.  In the body these are called free radicals, which can cause cell damage.

This video does a really good job of looking at the health benefits of negative ions from a scientific perspective.
