Can Harmattan Really Cause Madness?

There is nothing one will not hear in this country, I wonder if you have read this report in the media recently, that was examining the veracity or otherwise the belief relating insanity to Harmattan and full moon. What do you make of that?  I'm really puzzled about the whole issue honestly or is it part of the Insanity? Me I wan run ooo!!! I beg wetin man pikin go do?
