I frame it not as turning a dial down, but as switching channel from practical problem-solver to emotional problem-solver.
Often when someone wants to talk about a situation involving difficult feelings, they're actually trying to process those feelings: to understand where the feelings are coming from, to be validated, and to be able to take a broader perspective.
You can help by being curious about what they're saying, reflecting it back to them in your own terms, explaining how what they're feeling is understandable, and offering context or alternative viewpoints. These are actually complex problem-solving skills, although they can all fall under the umbrella of what people mean when they say "to be heard".
As a man, I've realised that once my emotions feel validated and accepted, I relax and the practical solutions just pop into my mind.
