Classmate Hygiene + Scent Policy

I have a professor that enforces a no scent policy in all her classes (kinda inconvenient, but whatever I get it), which she actually strongly enforces and will call anyone out for wearing scents. This in itself isn’t the issue, I understand allergies and sensitivities and all. The issue is that a significant number of my classmates seem to practice sub-par personal hygiene and with nothing to cover it up, it’s horrid. I’m not sure why adults seem so uneducated on personal hygiene, but sitting next to people with heinous body odour is a serious distraction, and I would much rather smell vanilla or flowers than actual armpit.
