Can fans blowing over manga/books cause yellowing

[sparkmeii]

I noticed my 2nd bookshelf which holds all of my newer manga 0-5 months old already has books yellowing. The room where they are stored has no windows so the light isn't what is causing it. The only thing that I can think of is the fan that I have this fan that blows towards the bookshelf, and I live in MN so kind of thinking it might be something with the humidity and the fan blowing over my books.

UV is always present. Maybe put a humidity sensor in your room.
