0:40:510:40:55

Oh! Oh, hi there!

0:40:570:40:58

Oh, excuse me. I'm a wee bit tired today.

0:40:580:41:02

I was woken up in the night,

0:41:020:41:04

by noisy cats meowing outside my bedroom window.

0:41:040:41:08

BEEPING

0:41:080:41:09

I hear a beep, I see a flash, I wonder what they're going to ask?

0:41:090:41:15

Hi, Nina!

0:41:150:41:18

Hi, guys!

0:41:180:41:19

We have a question for you.

0:41:190:41:21

Why do we have to sleep?

0:41:210:41:23

That's a great question! Why do we have to sleep?

0:41:230:41:27

It's so important we sleep enough.

0:41:270:41:30

Come to my lab and we'll do some experiments to investigate.

0:41:300:41:34

See you soon, Nina. Bye.

0:41:340:41:36

Bye.

0:41:360:41:37

I need help to answer this, and I know just who to ask.

0:41:370:41:41

OK, neurons, time to get to work!

0:41:410:41:44

WHIZZING AND WHIRRING

0:41:440:41:47

FUNKY MUSIC

0:41:480:41:50

Neurons at the ready, Nina.

0:42:010:42:03

OK. Today's question is, why do we have to sleep?

0:42:030:42:07

Which neuron will be most useful in finding the answer?

0:42:070:42:11

-Me!

-Me!

-Me!

-Me!

-Me!

0:42:110:42:13

Will it be...fabulous Felix?

0:42:130:42:16

I can help so very much, if you need the sense of touch.

0:42:160:42:20

Will it be...beautiful Belle?

0:42:200:42:22

I send messages to brain from ear. If there's sound I'll help you hear.

0:42:220:42:26

Will it be...lovely Luke?

0:42:260:42:28

Looking and seeing, day or night, I'll help with your sense of sight.

0:42:280:42:33

Will it be...awesome Ollie?

0:42:330:42:35

If it's pongy or whiffy but you can't tell,

0:42:350:42:37

my messages help your sense of smell.

0:42:370:42:39

Or will it be baby Bud?

0:42:390:42:40

Sour, salty, bitter or sweet, I'm your taste buddy when you eat.

0:42:400:42:46

-It's ALL the neurons!

-Yippee!

-Yes!

0:42:490:42:52

Go, neurons! Go, neurons! Go, neurons!

0:42:520:42:56

Go, neurons! Go, neurons! Go, neurons!

0:42:560:42:59

All neurons hip-hop-happy to help, Nina.

0:42:590:43:02

Today's question is, why do we have to sleep?

0:43:020:43:05

As sleep is important for the whole of our brilliant bodies,

0:43:050:43:09

I need all the neurons to help.

0:43:090:43:11

I need to get the lab ready before the experimenters arrive.

0:43:110:43:15

'Teagan likes tennis, Olim likes sour sweets,

0:43:160:43:20

'Kirsty loves science, but they all want to know why we have to sleep.

0:43:200:43:24

So today, Teagan, Olim and Kirsty become the experimenters!'

0:43:240:43:29

-Hi, guys.

-Hi, Nina.

0:43:310:43:34

Welcome to my science lab. Come in.

0:43:340:43:37

Now, you asked, "Why do we have to sleep?",

0:43:370:43:40

which is a great question. Why do you want to know?

0:43:400:43:43

Because my mum always tells me to go to bed early to get good sleep.

0:43:430:43:48

And I want to know why.

0:43:480:43:51

I know my body really enjoys a good night's sleep.

0:43:510:43:54

Why do we sleep? We need to do some experiments to find out.

0:43:540:43:59

Let's start by using our senses.

0:43:590:44:01

Woo-hoo! A senses experiment. We're ready, Nina.

0:44:010:44:06

So, who in your family sleeps?

0:44:060:44:08

My mummy, my big brother, my daddy,

0:44:080:44:13

and me, my little brother, and my pets.

0:44:130:44:16

Yes, everyone, humans and animals, need to sleep some of the time.

0:44:160:44:21

But some of us need more sleep than others.

0:44:210:44:25

Here we have pictures of an adult, a child and a little baby.

0:44:250:44:29

And they're all sleeping.

0:44:290:44:31

Now, can you see the little zeds?

0:44:310:44:34

Well, these show us how much sleep each of them need.

0:44:340:44:38

So, who has the smallest amount of zeds next to them?

0:44:380:44:43

The grown-up.

0:44:430:44:44

And who has the most?

0:44:440:44:46

-The top one.

-And what's that?

-A baby.

0:44:460:44:49

Yes. Babies need to sleep a lot.

0:44:490:44:53

That's because sleep is important in helping their brilliant bodies grow.

0:44:530:44:58

Little babies have the most growing to do, so they need the most sleep.

0:44:580:45:03

You guys still have lots of growing to do, too.

0:45:030:45:06

You also need plenty of sleep, around 11 or 12 hours every night.

0:45:060:45:12

Hey, that's about the same as me.

0:45:120:45:15

This is Mr Bear. Do you want a wee cuddle? Yeah!

0:45:150:45:20

He's a teddy, not a real bear.

0:45:200:45:22

But did you know real bears are super-duper sleepers?

0:45:220:45:26

In fact, bears actually sleep all winter,

0:45:260:45:30

a great big, long sleep called hibernation.

0:45:300:45:33

You would need a really comfy bed to sleep all winter, Nina.

0:45:330:45:37

That's a very good point, Felix.

0:45:370:45:40

I'd like you guys to choose things from the table,

0:45:400:45:44

to make the comfiest, cosiest bed ever for Mr Bear's big sleep.

0:45:440:45:47

Off you go!

0:45:470:45:49

BALL SQUEAKS

0:45:490:45:51

-What was that?

-Look, a pillow!

0:45:510:45:54

A pillow. A pillow's good.

0:45:540:45:58

(Hard.)

0:46:020:46:04

BALL SQUEAKS

0:46:040:46:06

I'm not sure Mr Bear wants to sleep with a noisy, squeaky toy.

0:46:060:46:12

Ah, a snuggly blanket and a comfy cushion. Bliss!

0:46:120:46:16

Great work, guys. That bed looks SO cosy.

0:46:160:46:20

How did you decide what would be the best things to make the bed?

0:46:200:46:24

-We felt it.

-You felt things.

0:46:240:46:27

-Teagan, what did you put in the box?

-I put the blanket and the pillow.

0:46:270:46:34

-And what else is in with Mr Bear?

-The little bear.

0:46:340:46:37

-Why did you choose the little bear?

-Because it's soft.

0:46:370:46:41

Brilliant! So now Mr Bear has a quiet, comfy bed.

0:46:410:46:45

You might want to dim the lights, Nina.

0:46:450:46:47

Good thinking, Luke.

0:46:470:46:49

Best not to have too much light in the room if you're sleeping.

0:46:490:46:53

Hey, hey. So, now we know we all need to sleep,

0:46:540:46:58

especially children and babies, because sleep helps them to grow.

0:46:580:47:04

A quiet, darkened room, with a warm, soft bed, is best for sleeping in.

0:47:040:47:10

To find out more about why we need to sleep,

0:47:100:47:13

we need to go somewhere busy and exciting.

0:47:130:47:16

Oh, just a second...

0:47:160:47:19

(Sweet dreams, Mr Bear. Follow me, experimenters.)

0:47:200:47:25

'Off we go, for another adventure.'

0:47:290:47:32

Nina said it's somewhere busy and exciting.

0:47:320:47:36

Maybe it's the airport? Eeeoowww...

0:47:360:47:40

It looks busy, but I don't see any planes.

0:47:400:47:43

No, it's not an airport, but I've a feeling it's going to be fun.

0:47:430:47:48

-Hello, Mr Postman.

-Hello, Nina.

0:48:050:48:07

We're here to find out why sleep is important for our brain,

0:48:070:48:11

which is the thing inside our head that controls our body.

0:48:110:48:15

Do you see those envelopes Mr Postman was collecting?

0:48:150:48:18

-Yes, Nina.

-Well, those letters and cards

0:48:180:48:21

are like the new bits of information our brain collects when we're awake.

0:48:210:48:25

Every time we see, hear, smell, taste or feel something,

0:48:250:48:30

our brain takes in the information from our sense neurons.

0:48:300:48:34

That's us. We're Nina's sense neurons.

0:48:340:48:38

When we sleep, our brain gets a rest from taking in all this information,

0:48:380:48:42

but it still has a very important job to do.

0:48:420:48:45

To find out more, we're going to follow Mr Postman!

0:48:450:48:48

What is the postman doing?

0:49:040:49:06

-Sorting out the letters into different boxes.

-That's right.

0:49:060:49:10

It's important none of the mail gets lost

0:49:100:49:12

so Mr Postman is sorting everything into the right places.

0:49:120:49:16

This is just like what our brain does when we sleep.

0:49:160:49:19

It sorts through all the new information collected during the day

0:49:190:49:23

and stores it away safely so we can remember it later.

0:49:230:49:28

Scientists also believe that all this sorting out

0:49:280:49:31

is why we sometimes dream when we sleep.

0:49:310:49:33

I once dreamt that Ollie turned into a giant orange! Ha-ha-ha!

0:49:330:49:39

Really, Bud?

0:49:390:49:41

Our memories can get jumbled up when the brain sorts things out

0:49:410:49:45

so dreams can be a mixture of things we remember from yesterday

0:49:450:49:48

and things from ages ago.

0:49:480:49:51

-Thanks for your help, Mr Postman.

-No problem at all, Nina.

0:49:510:49:54

We now know that sleep is very important for our brains,

0:49:540:49:58

but why else do we need sleep?

0:49:580:50:01

-Time to go back to the lab for one final experiment.

-Yay!

0:50:010:50:04

Let's go! Bye!

0:50:040:50:06

This experiment should help explain what happens

0:50:080:50:12

when our bodies get tired.

0:50:120:50:14

OK, now, let's have a look at this little pig.

0:50:140:50:19

PIG OINKS

0:50:220:50:24

Now, does he seems sleepy to you?

0:50:240:50:27

-No.

-No?

0:50:270:50:29

He is full of energy. Come back here, pig.

0:50:290:50:34

If you switch on these other toys,

0:50:340:50:36

I think you'll find they're all pretty lively, too.

0:50:360:50:40

So, let's have a play!

0:50:400:50:41

Oh, dear. Looks like there's a problem.

0:51:000:51:03

Oh, what's happening to the toys?

0:51:030:51:06

-They're slowing down.

-They're broken.

0:51:060:51:09

Actually, the toys are fine, but they're running low on power.

0:51:090:51:14

Let's try charging the batteries and see what happens.

0:51:140:51:17

The toy's batteries need recharged, a bit like our bodies needing sleep.

0:51:170:51:24

We use up lots of energy all day,

0:51:240:51:27

and then we sleep, to let our bodies rest

0:51:270:51:30

and recover from all the activity.

0:51:300:51:34

Let's see if they're back to being lively little toys.

0:51:340:51:38

PIG OINKS

0:51:400:51:41

And the pig!

0:51:410:51:43

PUPPY BARKS

0:51:440:51:45

Oh! The dog.

0:51:450:51:48

Yes, the toys' batteries are definitely recharged.

0:51:480:51:52

So, you asked, why do we have to sleep?

0:51:560:52:00

I think we've answered it. Sleep is important for our body and brain.

0:52:000:52:05

It gives our body time to recharge after a busy day

0:52:050:52:10

and our brain time to sort out

0:52:100:52:12

the new information taken in from our senses, so we can remember them.

0:52:120:52:17

We all need sleep.

0:52:170:52:19

But children and babies need more than adults

0:52:190:52:22

as sleep is important in helping their brilliant bodies grow.

0:52:220:52:25

I hope that's answered your question.

0:52:250:52:28

-Thanks, Nina. Bye!

-Bye!

0:52:280:52:32

I really enjoyed myself today,

0:53:310:53:33

finding out that children need lots of sleep to help them grow.

0:53:330:53:37

It's been a marvellous day.

0:53:370:53:39

The experimenters made such a warm, comfy bed for Mr Bear.

0:53:390:53:44

Ah, it's been such a great day, man.

0:53:440:53:48

Seeing all those letters getting sorted so they don't get lost.

0:53:480:53:52

I've had a fabby day.

0:53:520:53:54

The toys had lots of energy after they were recharged.

0:53:540:53:59

Remember, everyone's body is different but they're all brilliant.

0:53:590:54:03

See you again soon. Bye.

Nina investigates why people have to sleep, with the help of her five sense neurons.

Experimenters Kirsty, Olim and Tegan visit Nina in her lab. They find out that babies and children need more sleep than grown-ups because sleep is really important in helping their brilliant bodies to grow. Next, they visit a post office and see the postman sorting the letters so they won't get lost. Nina explains that when people sleep, their brains sort out all of the information they have taken in from their senses during the day. It is thought that this helps us to remember things later on.

Back at the lab, the children play with some very lively toys. They see that when the toys' batteries run out, they stop moving. Nina recharges the batteries so that the toys can be full of energy again. She explains that people run out of energy too at the end of a long day. So they need to get plenty of sleep to give their brilliant bodies time to recharge.
