The idiom "blow away the cobwebs" likely originates from the visual metaphor of actual cobwebs. When a place or an area is left undisturbed for a while, cobwebs can accumulate, and clearing them away requires a gust of air or a physical action to refresh the space. This idiom is often used to describe the process of refreshing one's mindset or perspective when feeling mentally tired or uninspired.
