Why do we get Hiccups?
Everybody gets hiccups (also sometimes spelt ‘hiccoughs’). Even when babies are still in the womb they hiccup, which can feel very odd to their mother! But why do we get them and how can you stop them?
What are Hiccups?
Hiccups are caused by the diaphragm (pronounced DYE-uh-fram). This is a large, dome-shaped muscle that sits at the bottom of your chest cavity, below your lungs. When we breathe in the diaphragm tightens, helping to pull air into the lungs, and when it relaxes it forces the air back out again. Sometimes the diaphragm becomes irritated and instead of tightening smoothly it does it in a jerky way, which makes air suddenly rush into your throat. This air is stopped when it hits the voice box and makes the opening between the vocal cords close very suddenly. This is what produces the sound of the hiccup.

A Day in the Life of… a Structural Engineer
You might be starting to think about which subjects you want to study at school, perhaps you have even had a talk about careers.
One thing that is quite tricky to assess is what a job is REALLY like. Some jobs are quite easy to imagine, such as working as a teacher, because we see the work that teachers do every day. Some jobs are a bit of a mystery. What does an engineer actually DO? And what do you have to study, to become one?
Today we are introducing a new series of articles, which will show you the typical working life of people in many different professions. If you know someone who has an interesting or unusual career, ask them if they would agree to a short interview with us to show kids a day in their life.
We were lucky enough to interview Tasha Scott, who was happy to explain to us her studies and career as a Structural Engineer.
