Question

Why do we have tears when we cry?

Answer 1

I dunno, but it always feels good to have a good cry

Answer 2

When we cry we put pressure into our heads. This pressure causes a backup of tears into our eyes from our noses. We also increase our blood flow to our face and eyes, which causes an increase in the amount of tears. These two things cause our eyes to be over filled with tears. And because we have too many tears to fit into our eyes, they flow down our cheeks as we cry.

Answer 3

Three types of tears are generated by the human eye. Basal tears protect the eye and keep it moist. Reflex tears flush out the eye when it becomes irritated. And emotional tears flow in response to sadness, distress, or physical pain.

Studies have shown that emotional tears contain more manganese, an element that affects temperament, and more prolactin, a hormone that regulates milk production. Sobbing out manganese and prolactin is thought to relieve tension by balancing the body’s stress levels and eliminating build ups of the chemicals, making the crier feel better.
