When we become emotional or upset our brains produce chemicals and hormones - including adrenaline - causing us to become stressed, and even more emotional. But one of the best ways to rid the body of these chemicals is to have a 'good cry'. The chemicals leave our bodies with the tears, leaving us refreshed and calm.

There are many things that make us feel like crying, and many reasons that we cry. We cry for happiness, sadness, pain, fear, frustration. What we'd like to know is, what makes you cry?

• Do you cry at weddings? And if so, why?

• Are you happy to cry in public?

• Have you ever cried with relief or frustration?

• Do you love someone so much that you find yourself crying for no other reason than that?

• Has something unexpected made you cry?

• Would you cry if you argued with your other half, or a family member?

• Will you cry if England doesn't win the World Cup?

• Do sad films or books make you cry?

• Music can affect our emotions enormously. Is there a piece of music that makes you cry, and is it with happiness or sadness?
