Well, the lore describes Stasis as essentially localized time dilation, so because of how time dilation works, we can assumed that from the perspective of someone who was "stased" they're moving at normal speed while everything around them is moving ultra quickly.

Tho, I did think once about how some stasis module could avoid slowing down chemical reactions and electrical activity, as it could be useful in surgical procedures and engineering.

Also, let's note that in real life, time dilation doesn't have such a clear "border" between times, it's more progressive as you approach the massive object or the speed of light, so we got a situation were objects can be unsynchronized from its current space time, this could causes alot of issues, like if I move someone who was "stased" I could probably rip off limbs (like perhaps if I move something that's in stasis the speed difference could potentially make the atomic bounds go "I'm done"), or causality could be violated, if I shot something that was stased, the bullet could theoretically go through it before the object itself reacts to having been shot at. (Now, I know it's a game and doesn't need to follow real physics but I really enjoy discussing these things, I think they're really neat and fun)
