We don't learn things about the world through one or two of our sensory organs. We're constantly taking in data from an infinite number of sources. We can tell it's going to rain when the air feels humid and smells like a storm. We can tell a room needs to be cleaned by the discomforting scent of mold. When sand or smoke gets in our mouth, we know the taste of it.
When we limit our character's observations of the world around them, we're shrinking the window through which a reader can see into the story we've created. The smallest details can add a new layer of understanding to characters or scenes. Is your protagonist's mother's meatloaf savory and delicious, or dry and bland? The former shows she cares about the food she puts in front of her family, the latter can indicate that she's overworked or careless. When a character walks into her crush's bedroom, does it smell clean or dirty? Do clothes feel soft, silky, scratchy, coarse? All of these things can show readers little things about your world so you don't have to tell them.
You should be careful not to overdo it, but you can get very clever with what you reveal through sensory writing. Maybe your villain wears a telltale perfume or cologne that shows up periodically throughout the story. Use food as a metaphor for family life -- cold, lifeless food for the family that doesn't cook and can't stand each other; warm, comforting meals for the messy but love-filled life of a happy family. Indicate social status through textiles worn. There are so many options.
Are you a sensory writer? What's your favorite sense to write? I love writing taste.
