How are we crying when we are sad?
Crying can be scientifically defined as the shedding of your tears in response to an emotional state.
When a tear is produced from the lacrimal gland that sits in-between your eyeball and eyelid, you spontaneously blink, spreading the tear as a film across your eye.
The three type of tears are: basal, reflex and psychic tears. Your basal tears  ‘worker tears’ and they keep your cornea (the transparent front of your eye) nourished and lubricated so your eyes don’t dry out.
 Your reflex tears which that help you to wash out any irritations to your eyes from foreign particles or vapours (onion, being the classic example).
The psychic, or ‘crying’ tears:These are the tears produced in response to that strong emotion you may experience from stress, pleasure, anger, sadness and suffering to indeed, physical pain. Psychic tears  contain a natural painkiller, called leucine enkephalin.
