Why Do We Cry When We're Sad and What’s the Purpose of Tears?

We cry when we're sad because our body wants to help us feel better. Tears are like a special kind of medicine, they clean our eyes and make us feel calmer inside. When you’re really upset, your brain sends out signals that tell your tears to come out. It's like your body is saying, 'I know this hurts, but I’ll help you feel better soon.'
