You Have a Sense You've Probably Never Thought About — and It Lets You Touch Your Nose With Your Eyes Closed
Proprioception is the sense of your own body's position in space, working without any help from your eyes — it's how you know where your limbs are, even without looking at them.
Beyond the five classic senses, the body has an extra, lesser-known system: proprioception, the sense of body position, sometimes called "deep touch."
Receptors in your muscles, tendons, and joints constantly feed your brain information about how each part of your body is positioned — no looking required.
It's this sense that lets you touch a fingertip to the tip of your nose with your eyes closed, climb stairs without looking at your feet, or adjust your glasses without ever seeing your own hand.
When this sense breaks down — through rare neurological disorders, for example — simple acts like standing or walking become a precarious task requiring total visual concentration, because the body simply stops "knowing" where it is.
