When something subsides, it:

When something subsides, it refers to a reduction in intensity or severity. This term is often used in contexts like weather events, emotions, or physical sensations. For example, after a storm, the wind and rain would subside, indicating that they have decreased in strength or intensity.

This concept aligns perfectly with the notion of wearing off or dying down, as it suggests a gradual easing or calming of a situation rather than the intensification or sudden return associated with the other options. Subside conveys a sense of relief or return to a normal state, making the idea of something decreasing or diminishing its influence highly relevant.
