I pulled that one from a google search, so the parameters may be hookey.
Try this one:-

This is a good demonstration of the effects..

I don't think it's the differential between feet and head, since the effect doesn't cut in until you turn your head. The problem is that the coriolis effect affects the fluid in the inner ear, so your sense of balance tells you that you are tilting over, while your eyes are telling you that the floor is level.
The way to mitigate it is to keep looking into the direction of rotation of the habitat.

As I recall it’s a factor of how large the radius of the spin device and it’s RPM's is as the delta of the centripetal force's impact on the feet and head will be too great…
According to the always great Atomic Rockets site, their thesis is that it’s a fucntion of RPM - 2 RPM is fine for most people, and anything above that will require training. For a shirtsleeves 1g environment, at 2 RPM you will need it to be well over 100m in radius.
I did a campaign using FFS as the ship design system years and years ago with a large TL 8/9 empire. All of their ships had spin gravity (normally only deployed while they were in jump). However that made the smallest possible ship in the 5 - 10k Dton range.

There must be some speed or other characteristic where this doesn't apply or we'd be sick all the time as Earth is translating and rotating every moment. Wonder what the boundary values for notable symptoms are....
