What is full moon ion effect?

it is theorized that around the time of a full moon, positively charged ions (cations) are more abundant in the air leading to irritation of many systems of the body. in a nutshell, people get grumpy during a full moon because they dont feel good. negative ions (anions), which are abundant in the air after a spring thunderstorm or at the bottom of a crashing waterfall, are a result of friction on the air and make us feel good.
