Question

Why do tears come out of our eyes when we feel depressed?

Answer 1

Tears do come out of our eyes when we are emotional, either very sad or happy or when our eyes are irritated by something.

Tears are needed for our eyes to work properly. Your eye has special parts called glands that make tears all day. Normally they only produce a tiny amount of tears less than half a teaspoon per day. Tears are mostly water and a little bit of salt, but they also have some oil, mucus and chemicals called enzymes that kill germs.
