There seems to be a ubiquitous minhag for women to wave their arms around when they light candles, let's say for shabbos. I don't mean covering their eyes with their hands I mean waving around in the air beforehand. Here's a video in case you aren't familiar.
What is the source or reason for this minhag? How old is it? I'm hoping for textual sources.
Note: I read in Rabbi Reisman's book Pathways of the Prophets that he looked into it and couldn't find any source or reason for it. I'm hoping the community here will have more success.
