What is the purpose of actually having tears when we are sad? We lose salt and water but how does that help us?

Great question! I’m waiting for an answer now. I read that women/people scream when they are startled or scared because it is a throwback to our ancestry as a way to warn of danger. Which makes sense. But I can’t come up with any reason why we cry tears based on emotion, not grit in our eyes.
