“Perhaps our eyes need to be washed by our tears once in a while, so that we can see Life with a clearer view again.”
Our tears are made out of lipid (oil), water and mucus and are secreted from the lacrimal glands at the back of the top eyelid.
Humans produce 3 types of tears:
Basal: Antibacterial tears to keep the eyes moist.
Reflex: Tears formed when the eyes are faced with pollutants like wind, dust, etc.
Emotional: We cry when we are sad, happy or mad!
How do these emotions trigger the tears?
? When we are emotional, a part of our brain that controls our emotions send a signal to switch on the “tear waterfall” or the largest tear gland.
? The effect of this is it makes more tears than our eyes can hold so the tears fall of and run through our cheeks.
? Also, the drainage system that drains out any extra tears is now coming to work. This is why normally when you cry, your nose starts to run, as the drainage pipe runs through the nose.
A good cry is cathartic…
? When you cry out of sadness, grief, stress or pain, the tears release various ‘feel-good’ chemicals.
? These chemicals released from these tears are actually different from normal tears (lacrimation). This is why our body feels better and you feel a huge sense of relief after you cry.
? One is forced to soothe oneself through deep breaths, which eventually helps in calming the nervous system and enhancing the mood.
Other teary benefits:
? Kills bacteria and germs: as tears release ‘lysozyme’ a natural antimicrobial cleaner.
? Prevents dryness: tears keep the eyes lubricated and moist and prevent the muses membrane from drying up.
What a crocodile tears?
? A saltwater crocodile releases excess salt via ‘crying’, so the term is used to signify a fake emotional cry-fest!
Now you know that actually when you cry, it’s not just water coming out, but actually a complex plumbing process that your body goes through!
