I am reading that Ionizers will reduce serotonin levels in a room..

this isn't a good thing for lucid dreaming I think..

From
http://www.causeof.org/sis.htm
"Negative ions accelerate the oxidative degradation of serotonin whereas positive ions have the opposite action and inactivate the enzymes which break down serotonin."

Any ideas / thoughts / opinions / other research / different experiences..?
