I have that problem, too. Yesterday I was reading about how the weather affects the percentage of positive and negative ions in the air. You can google that and find a list of effects that has on some people. If she can improve her own electrical system, it might not bother her so much, but til then, she can get an ionizer to change the atmosphere in her work area. Yesterday was so bad here that I almost bought one on the spot.
I hope that helps.
