Partway through this process, Jim perceives the ground approaching him at a stately pace, almost friendly. He's too far gone to figure out if it's because his perception of time is gone, his perception of space is gone, he's managing to catch himself, or Jedao is catching him.

He's unconscious before he can figure it out.

And it is unconsciousness, not sleep. His breathing is shallow, and his heartbeat is fast and not totally regular. Skin is warm, but it might just be from the warm shower water.

As it happens, he'll be fine without intervention, because he would have been fine without intervention. But whatever last reserve was sustaining him during his interaction with Jedao, it's gone.
