Smells of the Mozart Effect claims, but this one seems to have also have some scientific experiments behind it.
Apparently, listening to Mozart reduces “allergic skin wheal responses in atopic dermatitis patients”:http://findarticles.com/p/articles/mi_m0GDQ/is_1_29/ai_n6032933.
Sounds pretty out there, but there’s no harm in trying I guess. The same researcher, Hajime Kimata, has also written about how laughter, kissing, and crying with tears all beneficially modulate the body’s allergic response.
*Update*: “Here’a an article”:http://www.newscientist.com/article.ns?id=dn4918 talking about the molecular basis for the Mozart Effect. It’s from 2004, and seems less controversial than the original study.
