Key ideas in Why Crying Makes Your Nose Run
- Fluid leaking from your nose during crying is largely the overflow of tears traveling through an internal facial drain
- Your nasal lining mixes in a small amount of moisture, but the sudden volume comes directly from your eyes, not newly manufactured snot
- Each eyelid has a tiny visible opening called a punctum near the inner corner by the nose
- These openings act like miniature sink drains that constantly pull fluid off the eye
- Tears first enter through the small punctum holes at the corner of the eyelids
- The fluid travels down through a narrow internal tube (the nasolacrimal duct) beside the nose bone
- The duct empties directly into the lower nasal cavity, letting fluid spill into the nostrils
- Your eyes produce a baseline level of tears all day long that continuously drain into your nose
- Normal breathing pulls air across this steady moisture, quietly evaporating it to help keep nasal passages humid
- Heavy sobbing makes the main tear gland produce fluid far faster than the tiny eyelid drains can swallow
- Because the drains cannot keep up, tears spill over the lids and run down the cheeks
- The volume that does enter the drain overpowers the nose's ability to evaporate it, causing a rapid, watery runny nose
- Excess tears drain from the inner corners of the eyes straight into the nasal cavity through tear ducts
- Normal nasal mucus sits as a thick, sticky protective gel
- The rush of watery tears rapidly thins this resting mucus into a fast-running liquid
- Warm tear fluid entering the nose triggers local blood vessels in the nasal tissue to expand and dilate
