Morphology
The meaning is directly and transparently derived from 'use' (apply) + 'one's' (possessive) + 'noggin' (colloquial 'head'), so a learner who knows the constituents can infer 'use your head' → think or be sensible. This figurative mapping (use the head = think) is common across languages and regular in English, making the expression predictable to B1 learners who know the words.
Etymology
Use one's noggin comes from noggin, a friendly old word for the 'head'. Imagine tapping your head to remind yourself to think, and that's why it means 'to think carefully' or 'use common sense'.
