How Tears Find Their Way Into Your Nose
Each eyelid has tiny openings near its inner corner, called tear puncta. When you blink, tears spread across the eye and collect along the eyelid edges; some then pass through these openings into narrow channels. The channels lead to a small holding space beside the nose, then a duct that empties inside the nasal cavity.
This drainage happens all the time, even when you are not crying. Most tears quietly leave the eye this way rather than running down your cheeks.
Why Crying Makes the Drip Noticeable
Emotional crying produces tears faster than the drainage route can carry them away. Some spill over the eyelids, while more travels through the duct into the nose. There, the watery tears join the mucus that already moistens the nasal lining, making it thin and runny.
That is why the nose can start dripping along with the tears—and why wiping or blowing it may help, even though the fluid began in the eyes. The same small drainage route that keeps ordinary tears from pooling on the eye becomes a noticeable outlet when tear production surges.
