Bioshock Infinite "motion sickness"? Or did I eat something disagreeable?

As a few tips:

4) Don't crouch.

I am curious about topic 4. Why would that help? any theory?

Crouching makes you move more slowly, and I always find that moving slower than expected triggers motion sickness for me. It was even worse in the original BioShock where you would sway side to side when crouch walking.

I find it's only temporary until I give it a few seconds to get used to it, but I imagine it's more severe in some other people.
