How Much Sleep Do Kids Need?
Julianne Robertson investigates the world of snoozes, forty winks, cat naps and snoring. What is SLEEP, why do we need it, and how much sleep do kids need?
A couple of nights ago I was feeling really, really tired, so I went to bed early. I slept soundly, without even dreaming, until about 5am, when I woke up. It felt like I’d only been sleeping for about 5 minutes! After that, I fell back to sleep but had lots of vivid dreams and when I woke up a couple of hours later, it felt like I’d been asleep for a long time. After all that I still felt well-rested and was ready for the day.
All this made me wonder – what IS sleep? Why is it that some nights we feel like we’ve had a really good nights’ sleep, while other nights we still feel tired when we wake up in the morning? Here’s what I’ve discovered about sleep…
Princess Leia – The Warrior Princess
I love Star Wars. It’s my favourite trilogy of films ever. At least, I loved it when I was 8 and 9 and played Star Wars in the park wit my friends. I wasn’t overly fond of it when I was 6 years old and saw Empire Strikes Back for the first time. I still fast forward through the beginning bit of the movie where Luke Skywalker gets kidnapped by an abominable snowman on the planet Hoth and has to be rescued by Han Solo. It terrified me so much when I was 6 and saw it the cinema that my dad had to take me out.
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.
