Nasal odor worsens when on higher ground levels.

I've been noticing in the past two weeks that my nasal odor gets stronger when I'm on a higher ground level. When on a regular ground level, I never smell my nasal odor, but I take a class that's on the 5th floor in a building that's sort of open spaced. The only time you're actually inside is when you're in the classroom, because once you walk out of the classroom door, you are outside again. Okay, now once I reach the 5th floor the smell is just in full blast. It's this sweet, moldy type smell that is quite familiar now. I can smell it really well when on the 5th floor. At first, I thought it was that particular floor, so I tested each floor and the lower I went down, the less bad the smell was, until I reached the first floor where I could no longer smell my nasal odor. I'm not sure if people can smell my nasal odor or if it's just me who can smell it. Because, I breathe normally when people aren't sitting next to me or when the seats aren't ridiculously close, and I haven't gotten any reactions, but when someone is sitting next to me, I tend to hold my breathe for short periods, or lean against my hand with my elbow resting on the table, so that I'm breathing into my palm. I'm not sure if they can smell my nasal odor when sitting next to me, because I never breathe normally or I'm always breathing into my palm.

Anyway, does anyone know why this happens? Is it because the higher up you are the more or less air pressure there is or something?

I noticed something similar, but my bathroom is upstairs and since I put bleach in the sink it lessened. also there is more draft upstairs from my fans. i always smell myself when in cold air or breeze. it was a really cold winter day when i first noticed my nasal odor
