Don't treat your world as a static object that's observed. Make it alive, like an organism, interacting with your characters.
Let the air breathe, a cold gust making the skin creep. Let the door rattle, the wood creak making the ears ring. Let the lamp greet, the light glow making the pupils smaller.
This way, your world will feel alive (in your reader's perception), not just a backdrop.
