What is the biological reason why we cry when we are sad?

Question

i know that expelling tears from our eyes gets rid of irritants that enter our eyes, but why do we it when we're sad? or when we're feeling a strong emotion?

Answer 1

technically people don't cry when they're sad. They cry when they're frustrated or overwhelmed.

Answer 2

Tears flow from our eyes when we cry because they contain chemicals and hormones produced by our bodies.

When we become upset, our brains and bodies overreact and work overtime by producing chemicals and hormones.

Crying helps eliminate these extra chemicals that we don't need.

The chemicals and hormones disappear from our body through the form of tears. As our tears flow, they sooth our sadness or distress by withdrawing these chemical agents.

That is why many people feel calmer or more refreshed after crying--because the tears get rid of these hormones that are produced when we are sad, happy, or distressed.

Answer 4

not necessarily sad, but as you said, strong emotion.

Euphoria, stress, sad, shocked.....all of these when they are strong enough will stimulate tears.
