I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Organs Zone. It has scientists studying health and disease in various parts of our bodies. Who gets the prize? YOU decide!
Lack of sleep can have a really harmful effect in the brain!
It causes problems in the areas of the brain important for focussing, learning, memory and many others!
The brain is still busy during the time you are sleeping, but it also uses this time to help your body repair the other things that are not working properly!
Not enough sleep is not just bad for the brain. It can cause….
* aching muscles
* confusion, memory lapses or loss
* depression
* hallucinations
* hand tremors
* headaches
* malaise
* sensitivity to cold
* bloodshot eyes
* periorbital puffiness, commonly known as “bags under eyes” or eye bags
* increased blood pressure
* increased stress hormone levels
* increased risk of diabetes
* increased risk of fibromyalgia
* irritability
* nystagmus (rapid involuntary rhythmic eye movement)
* obesity
* temper tantrums in children
* yawning
* symptoms similar to Attention-deficit hyperactivity disorder(ADHD) and Psychosis
It’s a good reason to get enough sleep, right

The brain is like the head office (pun intended!) , and is involved in everything.
It needs some time to shut down and rest – think of it as cooling off.
Lack of sleep affects the brain is ways that Hannah has mentioned. Non of these are good (obviously!)
Not enough sleep will result in your body functioning at a sub-par standard as you can’t focus and your body and brain tells you that it’s upset/hasn’t had enough sleep by being groggy and lazy.

As the mother of two children, I can tell you that it has been at least eight years since I’ve had enough sleep. The biggest problems that I can tell you about through personal experience are: extreme crankiness, depression, loss of IQ, and dangerous driving.
One day my children will let me sleep….

Among the many consequences of sleep deprivation, deficits in attention and working memory are perhaps the most common. Sleep is critical for the brain to replay the events of the previous day – scientists have shown this in rats! People who are sleep deprived have higher levels of stress hormone which can stop new brain cells growing and kill existing ones. Ouch! The brain needs sleep.
