Question

Can we cry underwater?

Answer

Yes, it is possible to cry underwater. Tears (a water-based fluid containing salts, lipids, and proteins) are released by a structure called the lacrimal gland, located in the upper, outer region of each eye. In theory, being underwater does not prevent the lacrimal glands from releasing tears. Of course, such tears would be difficult to detect because they would immediately mix with the surrounding water. I recommend that you do not try crying underwater, as crying sometimes involves gasping and an increased breathing rate - two things that may be dangerous to experience while underwater.
