Onions are not just Shrek's favorite metaphor they are also the only vegetable that can make us cry when we chop them up but why do onions make us cry lets find out below.
Human beings have three distinctly different type of tears emotional tears, basal tears and reflexive tears. The emotional tears may be the most memorable type of tears. There's the kind we cry when we are hurt, upset or emotionally stress cutting up onions does not cause emotional tears unless you are particularly passionate about root vegetables.
Basal tears do not run down your cheeks like emotional tears it's more like a protective layer of liquid that always covers your eyes. Every time you blink your eyelid your eye with a new basal that's why your eyes would dry out if you stop blinking but basal tears don't have much to do with why we cry when we cut up onions. So that just leave us the third kind of tear Reflexive tear or eyes well up with reflexive tear whenever other outside particles get in your eyes. This is usually caused by things like dust, wind, ions, smoke and you guessed it onion vapors. Okay so now we know what type of tears make us cry over onions but why what about onion irritate our eyes enough to make us tear up.
Well when you cut into an onion you are slicing through the onion cells which causes chemical reactions inside the broken cells that reaction causes a gas to form that's irritating to the eyes of most station causes the brain to send the frets of tears to eyes and voila do crying while cutting up onions and now you know why onions make you cry.
The End Notes
If you wanted that the onion do not make you cry so before cutting onion you store onion into water and its releases its gases into water not in your eye. Thank you for viewing my post and do not forgot like and leave comment in comment section below.
