Question

Why can't we cry under water?

Answer 1

The act of crying has been defined as "a complex secretomotor phenomenon characterized by the shedding of tears from the lacrimal apparatus, without any irritation of the ocular structures".
 
So basically, crying is an emotional state where in we start shedding tears, but that doesn't not mean that you cannot be sad/ happy underwater and start shedding tears.
 
Of course those tears would get mixed with water but still it does imply that we can cry underwater.


ok

Answer 2

No, it is not possible to cry under water, because crying requires breathing rapidly and since you can'tbreathe underwater, unless you can, you will most likely drown from excess of water in your mouth/lungs. ... The tears would simply be absorbed into the water as they came out of your tear ducts.
