By the way, the whole point of Warp technology is so that you don't have to worry about what happens to the human body when accelerating to FTL speed. The idea is that you WARP the fabric of the universe around you so you aren't really moving, you are making the universe move around you.

The inertial dampers (dampeners?) are mostly for protecting the occupants during sub-light (Impulse engine) maneuvering and holding the structure of the ship together under serious stress.
