The corner-picture is of where the wall at the back of my shower meets the ceiling, and the picture with the vent is of the bathroom ceiling itself. In the first picture, I've noticed that the ceiling has started to separate from the white piece of wood between it and the wall, with the crack starting out a little wider at the corner-end before getting smaller and thinner as it continues along the length of the wall to the right, as though the wood has begun to warp. Its bottom-edge also seems to be wearing away from where it meets the wall.
The second picture shows a crease running across the width of my bathroom ceiling, with a much shorter, much fainter crease running parallel to it, about four or five inches to the right (might be harder to see in the picture). The space between the two creases is faintly bowed.
What would be the cause of these issues, and how should I approach repairing them, as well as preventing them from reoccurring?
