-Welcome to... -Operation Ouch! | 0:00:02 | 0:00:03 | |
This very special show is about something that happens to all of us. | 0:00:03 | 0:00:07 | |
Can you guess what it is? | 0:00:07 | 0:00:09 | |
Well, here's a clue. | 0:00:09 | 0:00:11 | |
-Spotty. -Angry, emotional. | 0:00:11 | 0:00:13 | |
Don't worry about it, everyone goes through it. | 0:00:13 | 0:00:15 | |
Be happy, it's normal, it's not scary. | 0:00:15 | 0:00:17 | |
Erm... | 0:00:17 | 0:00:19 | |
THEY LAUGH | 0:00:19 | 0:00:20 | |
Now, did you guess what those people were talking about? | 0:00:22 | 0:00:24 | |
That's right, it's puberty. | 0:00:24 | 0:00:26 | |
Now, Xand, did you notice how | 0:00:26 | 0:00:28 | |
all those people didn't seem to want to talk about puberty at all? | 0:00:28 | 0:00:31 | |
I did, Chris. | 0:00:31 | 0:00:32 | |
-LAUGHING: -There's a question! -There IS a question, isn't there? | 0:00:32 | 0:00:34 | |
BOTH: Erm... | 0:00:34 | 0:00:36 | |
But don't panic, | 0:00:36 | 0:00:37 | |
because on "Operation Ouch!" there's NOTHING we're afraid to talk about. | 0:00:37 | 0:00:40 | |
-Well, apart from... -Ssh! | 0:00:40 | 0:00:42 | |
Oh, yeah, sorry, right. | 0:00:42 | 0:00:43 | |
-So, puberty, get ready! -We're taking you on. | 0:00:43 | 0:00:46 | |
Coming up on this special "Operation Ouch!", | 0:00:49 | 0:00:52 | |
we show you how puberty affects your voice... | 0:00:52 | 0:00:54 | |
Ow! | 0:00:54 | 0:00:55 | |
..why not to worry about acne... | 0:00:55 | 0:00:57 | |
I had it all over the face, the back, the neck. | 0:00:57 | 0:01:01 | |
..and we offer some serious survival tips. | 0:01:01 | 0:01:03 | |
But first, what is puberty? | 0:01:06 | 0:01:08 | |
Think of it like this. | 0:01:10 | 0:01:12 | |
You've been growing since the moment you were born, | 0:01:12 | 0:01:14 | |
and it's what turned you from a little baby into a child. | 0:01:14 | 0:01:17 | |
But pretty soon, you need to go from being a child | 0:01:18 | 0:01:21 | |
into being an adult, or else the world would be full of children. | 0:01:21 | 0:01:24 | |
And this is where puberty comes in. | 0:01:24 | 0:01:27 | |
It's basically just another phase of growing. | 0:01:27 | 0:01:29 | |
And it's completely normal. | 0:01:29 | 0:01:32 | |
You might have already noticed changes in your body, | 0:01:32 | 0:01:34 | |
or perhaps you haven't, because everyone is different. | 0:01:34 | 0:01:37 | |
Usually it begins any time from the age of eight, | 0:01:37 | 0:01:40 | |
carrying right through to the age of 18. | 0:01:40 | 0:01:42 | |
In this special "Operation Ouch!", | 0:01:42 | 0:01:44 | |
we've got loads to show you about what happens to your body. | 0:01:44 | 0:01:47 | |
On the inside and the outside! | 0:01:47 | 0:01:49 | |
One thing that changes when you hit puberty is your sweat, | 0:01:52 | 0:01:55 | |
and we're going to show you why. | 0:01:55 | 0:01:58 | |
Does anybody want to smell my armpits? | 0:01:58 | 0:02:00 | |
Do you want to smell my armpits? | 0:02:00 | 0:02:02 | |
Free sweat-smelling here. | 0:02:02 | 0:02:03 | |
Can I tempt you, a little whiff? | 0:02:03 | 0:02:05 | |
Anyone? Anyone? | 0:02:05 | 0:02:07 | |
I don't seem to be having much luck for some reason. | 0:02:07 | 0:02:10 | |
Sweat. | 0:02:10 | 0:02:11 | |
It might seem a bit yucky, but everybody does it. | 0:02:11 | 0:02:14 | |
Sweating is what your body does when you get too hot, | 0:02:14 | 0:02:17 | |
and when that sweat evaporates, | 0:02:17 | 0:02:19 | |
it takes heat away from your body and prevents your internal organs | 0:02:19 | 0:02:23 | |
from overheating, so it's actually pretty wonderful stuff. | 0:02:23 | 0:02:26 | |
I'm not sure why nobody wants to smell mine. | 0:02:26 | 0:02:30 | |
HE GROANS | 0:02:31 | 0:02:32 | |
There are two types of sweat glands, | 0:02:33 | 0:02:35 | |
eccrine and apocrine. | 0:02:35 | 0:02:37 | |
Eccrine are the most common. | 0:02:37 | 0:02:39 | |
You have over two million of them all over your body. | 0:02:39 | 0:02:41 | |
Apocrine glands are only in particular places | 0:02:42 | 0:02:45 | |
like your groin and under your arms. | 0:02:45 | 0:02:47 | |
They produce a different type of sweat that is rich in protein | 0:02:47 | 0:02:50 | |
and fatty acids. | 0:02:50 | 0:02:51 | |
They only become active during, you guessed it, | 0:02:52 | 0:02:55 | |
puberty. | 0:02:55 | 0:02:56 | |
When your apocrine glands start working, | 0:02:56 | 0:02:58 | |
it changes how you sweat. | 0:02:58 | 0:03:01 | |
And this lot are going to help me show you what that means. | 0:03:01 | 0:03:04 | |
First, we're going to need a sample. | 0:03:04 | 0:03:06 | |
In fact, two samples. | 0:03:06 | 0:03:08 | |
One sample is made up of a group of eight-year-olds | 0:03:08 | 0:03:11 | |
who haven't started puberty yet. | 0:03:11 | 0:03:13 | |
The other sample is made up of 14-year-olds, | 0:03:13 | 0:03:15 | |
who are slap-bang in the middle of it. | 0:03:15 | 0:03:17 | |
And what I need from all of you now is sweat. | 0:03:17 | 0:03:20 | |
Are you ready? | 0:03:20 | 0:03:21 | |
-ALL: Yeah! -Right, let's go. | 0:03:21 | 0:03:23 | |
For the next half hour, | 0:03:24 | 0:03:25 | |
I'm getting both squads to train as hard as they can, | 0:03:25 | 0:03:28 | |
and sweat as much as possible. | 0:03:28 | 0:03:30 | |
What we're looking for here is real work. | 0:03:30 | 0:03:33 | |
It's not a race between the two teams. | 0:03:33 | 0:03:34 | |
We want quality, cos quality means sweat. | 0:03:34 | 0:03:37 | |
Ben, you sweating yet? | 0:03:38 | 0:03:39 | |
-Yeah. -Yeah? That's good. | 0:03:39 | 0:03:41 | |
After 30 minutes, I'm satisfied that both teams will have sweated enough. | 0:03:42 | 0:03:46 | |
It's time to collect all the sweaty shirts into separate bags. | 0:03:48 | 0:03:51 | |
Now we've got our samples. | 0:03:51 | 0:03:53 | |
The squads don't know which shirts are in which bag, | 0:03:53 | 0:03:56 | |
so let's see which smells worst. | 0:03:56 | 0:03:57 | |
One at a time, | 0:03:57 | 0:03:58 | |
you're going to smell each bag, | 0:03:58 | 0:04:00 | |
and tell me which you think smells worst. | 0:04:00 | 0:04:02 | |
Bag A is from the younger team | 0:04:03 | 0:04:05 | |
and Bag B is from the teenagers. | 0:04:05 | 0:04:07 | |
Which one do you think will smell worse? | 0:04:07 | 0:04:10 | |
-Get right in there. -That one. | 0:04:10 | 0:04:11 | |
Is it really disgusting? Huh. | 0:04:12 | 0:04:14 | |
That one. | 0:04:14 | 0:04:15 | |
What does this one smell of? | 0:04:15 | 0:04:16 | |
Like off vinegar. | 0:04:16 | 0:04:18 | |
I'll say this one. | 0:04:18 | 0:04:19 | |
You think that one smells worst? | 0:04:19 | 0:04:20 | |
This one. | 0:04:20 | 0:04:21 | |
And what do you think this one smells of? | 0:04:21 | 0:04:23 | |
-Rotten cheese. -Rotten cheese? | 0:04:23 | 0:04:25 | |
-Oh, that one. -Do you think this is your team? | 0:04:25 | 0:04:28 | |
-No. -You think the eight-year-olds are smellier than you? -Yeah. | 0:04:28 | 0:04:30 | |
Big breath in, Ben. | 0:04:30 | 0:04:32 | |
-This one. -XAND LAUGHS | 0:04:32 | 0:04:33 | |
-That one. -Really? | 0:04:35 | 0:04:36 | |
Cos, like, I smelt my own armpits and they stink more. | 0:04:36 | 0:04:40 | |
So which of you thought | 0:04:40 | 0:04:41 | |
that Bag B was the smelliest? | 0:04:41 | 0:04:43 | |
Yeah, all except two. | 0:04:44 | 0:04:45 | |
That's 12-2 to Bag B. | 0:04:45 | 0:04:47 | |
Now, THIS was the bag from the older ones. | 0:04:47 | 0:04:50 | |
So I think you're absolutely right, | 0:04:50 | 0:04:52 | |
this definitely should have been the smelliest one. | 0:04:52 | 0:04:54 | |
Now, do you know why? | 0:04:54 | 0:04:55 | |
-Because they're older. -Cos they're older, that's right. | 0:04:55 | 0:04:58 | |
And when you get older, you get different kinds of sweat glands, | 0:04:58 | 0:05:01 | |
they're called apocrine glands, | 0:05:01 | 0:05:03 | |
and make different sorts of sweat, and it's got more chemicals in, | 0:05:03 | 0:05:06 | |
which gets broken down by bacteria. | 0:05:06 | 0:05:08 | |
So what you're really smelling in here is bacteria poo. | 0:05:08 | 0:05:11 | |
ALL GROAN | 0:05:11 | 0:05:12 | |
There you go, you're the ones smelling it. | 0:05:12 | 0:05:14 | |
Not me, I haven't smelled it. | 0:05:14 | 0:05:15 | |
CHANTING: Smell it, smell it, smell it... | 0:05:15 | 0:05:17 | |
Oh, God, no! Oh! | 0:05:17 | 0:05:19 | |
-LAUGHING: -Eurgh! | 0:05:19 | 0:05:21 | |
Remember, all sweat is completely normal, | 0:05:22 | 0:05:25 | |
even the smelly variety. | 0:05:25 | 0:05:26 | |
And you could make sure you don't stay smelly | 0:05:26 | 0:05:28 | |
by washing yourself and your clothes regularly. | 0:05:28 | 0:05:31 | |
Speaking of washing, guys, | 0:05:31 | 0:05:33 | |
you better not forget to wash all your kits. Guys? | 0:05:33 | 0:05:36 | |
Guys! | 0:05:36 | 0:05:37 | |
Get ready to change shape. | 0:05:41 | 0:05:42 | |
Er... Not like that! | 0:05:44 | 0:05:45 | |
We're talking growth spurts. | 0:05:45 | 0:05:48 | |
Hormones kick in, telling your body to get taller. | 0:05:48 | 0:05:50 | |
Boys get broader, | 0:05:51 | 0:05:53 | |
girls get breasts, | 0:05:53 | 0:05:55 | |
and it can all be a bit annoying, | 0:05:55 | 0:05:57 | |
if you grow out of your favourite outfit too quickly. | 0:05:57 | 0:06:00 | |
But don't panic, it's exciting too. | 0:06:01 | 0:06:03 | |
You also get stronger... | 0:06:04 | 0:06:06 | |
Maybe not that strong! | 0:06:06 | 0:06:07 | |
Nice bus though. | 0:06:07 | 0:06:09 | |
But remember, it's all completely normal. | 0:06:09 | 0:06:11 | |
And it could be a whole lot worse. | 0:06:12 | 0:06:13 | |
If you were a baboon, | 0:06:13 | 0:06:15 | |
puberty would suddenly give you a giant red bottom. | 0:06:15 | 0:06:17 | |
As part of today's special show, we're looking at hormones. | 0:06:21 | 0:06:24 | |
Just don't try anything you see here at home. | 0:06:25 | 0:06:28 | |
-PHONE BEEPS -It's Chris. | 0:06:29 | 0:06:30 | |
PHONE BEEPS | 0:06:36 | 0:06:37 | |
OK, fair enough. | 0:06:40 | 0:06:41 | |
PHONE BEEPS | 0:06:42 | 0:06:43 | |
Well, I don't know where he keeps his custard creams, | 0:06:45 | 0:06:47 | |
-he hides them from me. -PHONE BEEPS | 0:06:47 | 0:06:49 | |
Oh, yeah, here they are. | 0:06:51 | 0:06:52 | |
PHONE BEEPS | 0:06:56 | 0:06:57 | |
Chris, why are you sending me all these ridiculous text messages? | 0:07:03 | 0:07:06 | |
I'm trying to work. | 0:07:06 | 0:07:08 | |
Well, I'm glad you asked me that, Xand, | 0:07:08 | 0:07:10 | |
it's not just because I want those custard creams, | 0:07:10 | 0:07:12 | |
although I do want them and you've written them in the logbook now. | 0:07:12 | 0:07:15 | |
It's because today's lab is all about hormones, | 0:07:15 | 0:07:17 | |
and like texts, hormones are messages | 0:07:17 | 0:07:20 | |
but they're chemical ones sent around your body. | 0:07:20 | 0:07:22 | |
You can't control them any more than Xand could control | 0:07:22 | 0:07:25 | |
the number of texts I was sending him. | 0:07:25 | 0:07:27 | |
You have hormones from the moment you're born, | 0:07:29 | 0:07:31 | |
telling the different cells in your body what to do. | 0:07:31 | 0:07:33 | |
Your pancreas makes the hormone insulin | 0:07:35 | 0:07:37 | |
to control sugar levels in your blood. | 0:07:37 | 0:07:38 | |
WHISTLE BLOWS | 0:07:40 | 0:07:41 | |
And your adrenal glands produce the hormone adrenaline | 0:07:41 | 0:07:43 | |
when you're excited or scared, | 0:07:43 | 0:07:45 | |
preparing your body for immediate action. | 0:07:45 | 0:07:46 | |
GORILLA GRUNTS | 0:07:46 | 0:07:48 | |
SHE ZOOMS | 0:07:48 | 0:07:50 | |
And then there's your pituitary gland in your brain, | 0:07:50 | 0:07:53 | |
and to show you what that looks like, | 0:07:53 | 0:07:54 | |
I've actually got a real sheep's brain in my hand. | 0:07:54 | 0:07:59 | |
Now the first thing you'll notice is | 0:07:59 | 0:08:00 | |
it's much smaller than a human brain. | 0:08:00 | 0:08:02 | |
And that's probably why sheep are less intelligent than human beings. | 0:08:02 | 0:08:05 | |
-Chris, there might be sheep watching! -Doesn't matter. | 0:08:05 | 0:08:08 | |
-They're sheep, they won't understand what I said. -All right. | 0:08:08 | 0:08:10 | |
Well, I've cut it in half | 0:08:10 | 0:08:11 | |
so you can see right here at the base of the brain | 0:08:11 | 0:08:15 | |
is the pituitary gland. | 0:08:15 | 0:08:16 | |
Now, take a look at this MRI scan of my actual brain. | 0:08:16 | 0:08:19 | |
And there's my pituitary gland right there. | 0:08:20 | 0:08:23 | |
Now it may be small, but it has a big job to do, | 0:08:23 | 0:08:26 | |
because it's the pituitary gland that controls | 0:08:26 | 0:08:28 | |
most of the hormones in your body. | 0:08:28 | 0:08:30 | |
But when you reach puberty, your hormones go into super charge mode. | 0:08:30 | 0:08:34 | |
They spring into action like never before, | 0:08:34 | 0:08:36 | |
and they're responsible for all the changes that take place | 0:08:36 | 0:08:39 | |
during puberty. | 0:08:39 | 0:08:41 | |
And one of these changes occurs in the voice box, | 0:08:41 | 0:08:43 | |
the organ which allows you to speak. | 0:08:43 | 0:08:45 | |
And we're going to show you what it looks like. | 0:08:45 | 0:08:48 | |
Now this is the larynx, | 0:08:48 | 0:08:49 | |
or the voice box of a young pig. | 0:08:49 | 0:08:52 | |
Your voice box is in your throat, | 0:08:53 | 0:08:54 | |
it's the tough rubbery bit here on your neck. | 0:08:54 | 0:08:57 | |
Now, I also have... | 0:08:57 | 0:08:58 | |
..a pig's larynx, | 0:09:00 | 0:09:02 | |
except that mine is bigger than Chris's, | 0:09:02 | 0:09:04 | |
and that's because it's from an adult pig. | 0:09:04 | 0:09:07 | |
Now one of these two larynxes | 0:09:07 | 0:09:09 | |
will have a deeper sound | 0:09:09 | 0:09:10 | |
than the other, but which one do you think it's going to be? | 0:09:10 | 0:09:14 | |
The bellows are acting like your lungs, | 0:09:14 | 0:09:16 | |
sending air past the vocal cords | 0:09:16 | 0:09:17 | |
which you can see here. | 0:09:17 | 0:09:19 | |
And they make a sound when they vibrate. | 0:09:19 | 0:09:21 | |
LARYNX SQUEAKS | 0:09:21 | 0:09:23 | |
Compare the sound of this smaller larynx... | 0:09:23 | 0:09:25 | |
LARYNX SQUEAKS | 0:09:25 | 0:09:27 | |
..to the sound of the larger one. | 0:09:27 | 0:09:29 | |
LARYNX BLOWS | 0:09:29 | 0:09:30 | |
Can you hear the sound of the larger larynx is deeper | 0:09:30 | 0:09:33 | |
than the smaller one? | 0:09:33 | 0:09:34 | |
LARYNX SQUEAKS | 0:09:34 | 0:09:36 | |
This change in sound is known as your voice breaking, | 0:09:36 | 0:09:39 | |
and it happens to both boys and girls. | 0:09:39 | 0:09:41 | |
Now, when YOU go through puberty, those hormones, | 0:09:43 | 0:09:45 | |
controlled by your pituitary gland, | 0:09:45 | 0:09:47 | |
tell your larynx to grow bigger, | 0:09:47 | 0:09:49 | |
and that makes your voice get deeper. | 0:09:49 | 0:09:51 | |
So, we've shown you that hormones | 0:09:52 | 0:09:54 | |
are messages | 0:09:54 | 0:09:55 | |
telling your body what to do. | 0:09:55 | 0:09:56 | |
When you start puberty, | 0:09:56 | 0:09:58 | |
your hormones become more active, | 0:09:58 | 0:09:59 | |
telling you to grow into an adult. | 0:09:59 | 0:10:01 | |
And remember, hormones are what make your voice break, | 0:10:01 | 0:10:04 | |
only nothing's breaking at all. | 0:10:04 | 0:10:06 | |
Your larynx actually gets bigger, | 0:10:06 | 0:10:07 | |
and that makes your voice deeper. | 0:10:07 | 0:10:09 | |
But whether you're a boy or a girl, | 0:10:09 | 0:10:11 | |
don't panic, because it doesn't hurt at all. | 0:10:11 | 0:10:14 | |
It's all completely normal. | 0:10:14 | 0:10:16 | |
It's definitely more obvious for us boys | 0:10:16 | 0:10:18 | |
because our larynxes grow more than girls', | 0:10:18 | 0:10:20 | |
and so it pushes this bit out. | 0:10:20 | 0:10:22 | |
It's called your Adam's apple. | 0:10:22 | 0:10:24 | |
Ouch, why don't you poke your own Adam's apple? | 0:10:24 | 0:10:26 | |
-It's more fun poking yours. -Stop it, it's really annoying. | 0:10:26 | 0:10:29 | |
Really annoying, like sending somebody loads of text messages? | 0:10:29 | 0:10:32 | |
PHONE BEEPS | 0:10:32 | 0:10:33 | |
How did he do that? | 0:10:36 | 0:10:37 | |
Get ready to get hairy. | 0:10:42 | 0:10:43 | |
OK, not that hairy, and don't worry, it's all completely normal. | 0:10:45 | 0:10:48 | |
It happens to every mammal on the planet. | 0:10:48 | 0:10:50 | |
Boys, you'll get hair on your face, | 0:10:52 | 0:10:54 | |
and everyone gets new hair on their legs | 0:10:54 | 0:10:57 | |
and armpits, | 0:10:57 | 0:10:59 | |
and between their legs. | 0:10:59 | 0:11:00 | |
That's called pubic hair. | 0:11:00 | 0:11:02 | |
In the animal world, getting hairy is the best way to attract a mate | 0:11:02 | 0:11:06 | |
because it holds on to smelly sweat, which is apparently very enticing. | 0:11:06 | 0:11:10 | |
But us humans have moved on a bit since we were apes, | 0:11:11 | 0:11:15 | |
so we don't need it. | 0:11:15 | 0:11:16 | |
Some people keep it, some remove it. | 0:11:16 | 0:11:18 | |
It's up to you. | 0:11:18 | 0:11:19 | |
Wherever you are in the UK, you can be sure that | 0:11:24 | 0:11:26 | |
the emergency services are on standby, ready to take on... | 0:11:26 | 0:11:29 | |
What? What? | 0:11:29 | 0:11:30 | |
What does this have to do with puberty? | 0:11:30 | 0:11:32 | |
I mean, I love the emergency services, | 0:11:32 | 0:11:34 | |
but how do they fit into this special episode? | 0:11:34 | 0:11:36 | |
They will, Xand, they will. | 0:11:36 | 0:11:38 | |
We're on call with the UK emergency services, | 0:11:39 | 0:11:42 | |
and today, Xand might get a few surprises. | 0:11:42 | 0:11:44 | |
Ooh! | 0:11:45 | 0:11:46 | |
On call with me is paramedic Jan Vann. | 0:11:46 | 0:11:48 | |
This is a rapid response vehicle, | 0:11:53 | 0:11:55 | |
and it's on standby 24/7 to respond | 0:11:55 | 0:11:58 | |
to whatever medical emergency calls come in. | 0:11:58 | 0:12:00 | |
-BEEPS HORN -Oh, sorry, Jan. | 0:12:00 | 0:12:02 | |
Bit embarrassing. | 0:12:04 | 0:12:05 | |
A new case is just in. | 0:12:06 | 0:12:08 | |
So we've had a 999 call to see a male with a problem with his head. | 0:12:08 | 0:12:13 | |
We know he's over 16, | 0:12:13 | 0:12:14 | |
we don't have any other details than that at the moment, | 0:12:14 | 0:12:17 | |
so this could be a huge range of things | 0:12:17 | 0:12:19 | |
and we need to get there as quickly as possible. | 0:12:19 | 0:12:21 | |
Oh, thank goodness you're here. | 0:12:27 | 0:12:28 | |
Chris? | 0:12:29 | 0:12:30 | |
Yeah, my hair is just SO greasy, | 0:12:30 | 0:12:33 | |
it's just like someone's dipped my head in a bucket of lard. | 0:12:33 | 0:12:35 | |
Dr Chris, you only call 999 in a real emergency. | 0:12:35 | 0:12:39 | |
Sorry, Jan. | 0:12:39 | 0:12:40 | |
It's not on! | 0:12:40 | 0:12:41 | |
That's what's known as a Jan Vann telling-off. | 0:12:43 | 0:12:47 | |
But since we're here, let's see what we can do for the, er... | 0:12:47 | 0:12:49 | |
CLEARS THROAT ..patient. | 0:12:49 | 0:12:51 | |
Tell me what's going on. | 0:12:51 | 0:12:52 | |
Oh, my hair's just really greasy, | 0:12:52 | 0:12:54 | |
and it's all lifeless and it feels oily, | 0:12:54 | 0:12:56 | |
so I just feel a bit embarrassed to go out with it. | 0:12:56 | 0:12:58 | |
And how long has this been going on for? | 0:12:58 | 0:13:00 | |
I don't know, like not just today, it's been going on for ages. | 0:13:00 | 0:13:03 | |
Let's have a quick look at it. | 0:13:03 | 0:13:04 | |
When you go through puberty, | 0:13:05 | 0:13:07 | |
the hormone changes that your body's going through | 0:13:07 | 0:13:09 | |
that are helping you grow up | 0:13:09 | 0:13:10 | |
stimulate your skin to produce more oil. | 0:13:10 | 0:13:13 | |
That oil's called sebum, | 0:13:13 | 0:13:14 | |
and it can make your hair really greasy. | 0:13:14 | 0:13:16 | |
Though to be honest, | 0:13:16 | 0:13:18 | |
I've never seen anyone with hair quite as greasy as Chris's. | 0:13:18 | 0:13:21 | |
What you need to do is wash your hair more frequently. | 0:13:22 | 0:13:25 | |
-Can you help? -Yeah. -Great. | 0:13:25 | 0:13:26 | |
OK, relax your head back. | 0:13:27 | 0:13:28 | |
-Is that nice, Chris? -Oh, it's really good. | 0:13:32 | 0:13:35 | |
Ah... | 0:13:35 | 0:13:36 | |
I suppose I could do this myself. | 0:13:37 | 0:13:39 | |
Well, you should be able to wash your own hair, really, | 0:13:39 | 0:13:42 | |
on a regular basis. | 0:13:42 | 0:13:43 | |
Oh, marvellous. | 0:13:45 | 0:13:47 | |
So, Jan, same time tomorrow? | 0:13:47 | 0:13:48 | |
No. This is definitely something that you can do for yourself | 0:13:48 | 0:13:51 | |
from now on. | 0:13:51 | 0:13:52 | |
Sorry. | 0:13:52 | 0:13:54 | |
If you've got greasy hair, | 0:13:54 | 0:13:55 | |
there are lots of things you can do. | 0:13:55 | 0:13:57 | |
There are special shampoos for greasy hair, | 0:13:57 | 0:13:59 | |
you can actually get water-free shampoos | 0:13:59 | 0:14:00 | |
which, for some people, work very well, | 0:14:00 | 0:14:02 | |
and you can get hair products which make your hair look less greasy. | 0:14:02 | 0:14:06 | |
The one thing you shouldn't do is call an ambulance. | 0:14:06 | 0:14:09 | |
And now, we're heading out and about for our puberty special. | 0:14:10 | 0:14:13 | |
At the clinic, Chris is open for business. | 0:14:15 | 0:14:18 | |
Next patient, please. | 0:14:18 | 0:14:19 | |
First in is ten-year-old Samantha, with some mystery marks. | 0:14:19 | 0:14:23 | |
So Sam, what brings you to the Ouch-mobile today? | 0:14:23 | 0:14:26 | |
I have some interesting stretch marks on my leg. | 0:14:26 | 0:14:28 | |
What's the diagnosis, doc? | 0:14:28 | 0:14:30 | |
Sounds like a case of | 0:14:30 | 0:14:31 | |
"I've got some interesting stretch marks on my legs-itis" | 0:14:31 | 0:14:34 | |
but don't panic. | 0:14:34 | 0:14:35 | |
So, Sam, open the eyelid. | 0:14:35 | 0:14:37 | |
So why don't you stand up and see if you can show us the stretch marks? | 0:14:38 | 0:14:41 | |
Oh, yeah, OK. You've got some streaks here, | 0:14:42 | 0:14:45 | |
and they're a little bit darker, aren't they? | 0:14:45 | 0:14:47 | |
The reason you get them is when you reach puberty, | 0:14:47 | 0:14:49 | |
a lot of people start to grow very, very quickly. | 0:14:49 | 0:14:52 | |
That dark bit is where you've pulled the skin fibres apart, | 0:14:52 | 0:14:56 | |
so where the skin is a bit thinner, | 0:14:56 | 0:14:57 | |
you can see through to the darker skin underneath. | 0:14:57 | 0:15:00 | |
So it's nothing to worry about. | 0:15:00 | 0:15:02 | |
EVERYONE has stretch marks. | 0:15:02 | 0:15:04 | |
I have them, and I have them in almost exactly the same place. | 0:15:04 | 0:15:06 | |
And it's very, very common. | 0:15:06 | 0:15:08 | |
Is there anything I can do to get rid of them? | 0:15:08 | 0:15:10 | |
There are some creams that you can get, | 0:15:10 | 0:15:12 | |
so there's a Vitamin E cream. | 0:15:12 | 0:15:14 | |
It doesn't work for everyone, | 0:15:14 | 0:15:15 | |
but putting some Vitamin E on them may help a bit. | 0:15:15 | 0:15:18 | |
But as you get older, | 0:15:18 | 0:15:20 | |
they may well just get lighter, | 0:15:20 | 0:15:21 | |
and you might not notice them. | 0:15:21 | 0:15:23 | |
Thank you very much for bringing your interesting stretch marks | 0:15:23 | 0:15:25 | |
-in to see me. -Thank you, Dr Chris, for helping me. | 0:15:25 | 0:15:28 | |
Away from the clinic, Xand is in the park, | 0:15:31 | 0:15:33 | |
taking questions about growing up. | 0:15:33 | 0:15:34 | |
Why am I getting clumsier as I get older? | 0:15:35 | 0:15:38 | |
What sort of things do you get wrong? | 0:15:38 | 0:15:40 | |
I always trip over my own feet. | 0:15:40 | 0:15:41 | |
As you get bigger, | 0:15:41 | 0:15:43 | |
your arms and legs are getting longer | 0:15:43 | 0:15:44 | |
and it's hard to know where they are, | 0:15:44 | 0:15:46 | |
cos you're used to them being a bit shorter. | 0:15:46 | 0:15:48 | |
Once you stop growing, you kind of get used to it, | 0:15:48 | 0:15:50 | |
but I'm still quite clumsy. | 0:15:50 | 0:15:52 | |
Dr Chris is really clumsy. | 0:15:52 | 0:15:53 | |
THEY GIGGLE | 0:15:53 | 0:15:55 | |
So the next time you get told off for knocking things over, | 0:15:55 | 0:15:57 | |
you've got the perfect excuse. | 0:15:57 | 0:15:59 | |
"It's just puberty." | 0:15:59 | 0:16:01 | |
Back at the Ouch-mobile, there's a new case in the waiting room. | 0:16:01 | 0:16:03 | |
Next patient, please. | 0:16:03 | 0:16:05 | |
It's double trouble! Cousins Rhea and Syrus. | 0:16:05 | 0:16:08 | |
So, guys, what brings you to the Ouch-mobile today? | 0:16:09 | 0:16:11 | |
Me and Syrus are both the same age, | 0:16:11 | 0:16:13 | |
so, 12, but I am a lot taller than him. | 0:16:13 | 0:16:17 | |
What's the diagnosis, doc? | 0:16:17 | 0:16:18 | |
This sounds like a serious case of | 0:16:18 | 0:16:20 | |
"me and Syrus are exactly the same age, 12, | 0:16:20 | 0:16:23 | |
"but I'm a lot taller than him-itis." | 0:16:23 | 0:16:25 | |
But don't panic. | 0:16:25 | 0:16:27 | |
Now let's see how much taller you are. Can you stand up? | 0:16:27 | 0:16:30 | |
Syrus, do you want to stand up next to Rhea? | 0:16:30 | 0:16:32 | |
So this is how tall Rhea is, and this is how tall Syrus is. | 0:16:32 | 0:16:36 | |
You're about a head shorter, | 0:16:37 | 0:16:38 | |
-and you're exactly the same age? -Yeah. -Have a seat. | 0:16:38 | 0:16:40 | |
So, what do you want to know about this? | 0:16:40 | 0:16:43 | |
I want to know why boys have their growth spurts later than girls. | 0:16:43 | 0:16:47 | |
We don't know why boys start later, | 0:16:47 | 0:16:49 | |
but girls can start kind of aged ten to 12, | 0:16:49 | 0:16:52 | |
and boys tend to start more like 12 to 14, 15. | 0:16:52 | 0:16:56 | |
So that's because your body starts releasing a hormone | 0:16:56 | 0:16:59 | |
called testosterone. | 0:16:59 | 0:17:00 | |
It's testosterone that makes both boys and girls | 0:17:00 | 0:17:02 | |
have this sudden growth spurt. | 0:17:02 | 0:17:03 | |
What's it like being shorter than your 12-year-old female cousin? | 0:17:03 | 0:17:07 | |
-Um... Annoying! -I just beat him up all the time. -Oh, man! | 0:17:07 | 0:17:09 | |
THEY LAUGH | 0:17:09 | 0:17:11 | |
I remember that, I remember getting beaten up by girls at age 12. | 0:17:11 | 0:17:14 | |
-Thank you very much, Dr Chris. -Thank you. -It's a real pleasure. | 0:17:14 | 0:17:16 | |
If you haven't had your growth spurt yet, don't panic, | 0:17:17 | 0:17:20 | |
everyone's different. | 0:17:20 | 0:17:22 | |
It will come. | 0:17:22 | 0:17:23 | |
Clinic closed. | 0:17:23 | 0:17:24 | |
Boys, this one's for you. | 0:17:25 | 0:17:27 | |
Get ready for your testicles dropping. | 0:17:27 | 0:17:30 | |
Don't panic, they don't literally drop off. | 0:17:30 | 0:17:32 | |
They just drop lower inside your scrotum as they grow a bit, | 0:17:34 | 0:17:37 | |
and it's totally normal. | 0:17:37 | 0:17:39 | |
It happens because your testicles start to make sperm. | 0:17:39 | 0:17:42 | |
Sperm are one of the things used to make a baby | 0:17:42 | 0:17:45 | |
when you're an adult, and they like to stay cool. | 0:17:45 | 0:17:47 | |
So your testicles need to hang lower outside your body | 0:17:47 | 0:17:51 | |
to be at just the right temperature. | 0:17:51 | 0:17:52 | |
Hey, what are you doing? | 0:17:52 | 0:17:54 | |
Just chilling. | 0:17:54 | 0:17:55 | |
And one testicle is usually lower than the other. | 0:17:57 | 0:17:59 | |
If it wasn't, you'd crush them between your legs. | 0:17:59 | 0:18:02 | |
But that doesn't mean it's cool to walk like an ape. | 0:18:02 | 0:18:05 | |
Remember, if you're worried about anything, | 0:18:05 | 0:18:07 | |
speak to an adult you trust. | 0:18:07 | 0:18:08 | |
Still to come on today's puberty special, | 0:18:10 | 0:18:13 | |
Chris and Jan are called out to a moody teenager... | 0:18:13 | 0:18:15 | |
What? | 0:18:15 | 0:18:17 | |
..there's more top puberty survival tips | 0:18:17 | 0:18:19 | |
and Chris finds out why puberty | 0:18:21 | 0:18:23 | |
can make getting up in the morning really tricky. | 0:18:23 | 0:18:25 | |
CHRIS, GET UP! | 0:18:25 | 0:18:26 | |
Now, did you know 80% of teenagers get spots | 0:18:29 | 0:18:32 | |
to some degree, and boys are more likely to get them than girls? | 0:18:32 | 0:18:36 | |
But remember, don't squeeze them. | 0:18:36 | 0:18:38 | |
Spots. | 0:18:41 | 0:18:42 | |
I used to get them, | 0:18:42 | 0:18:44 | |
I still do get them, | 0:18:44 | 0:18:45 | |
you're probably going to get them, | 0:18:45 | 0:18:46 | |
and nobody likes them. | 0:18:46 | 0:18:48 | |
But for some teenagers, | 0:18:48 | 0:18:49 | |
puberty can make spots a lot worse. | 0:18:49 | 0:18:52 | |
Clear. | 0:18:52 | 0:18:54 | |
So, why does puberty make spots worse? | 0:18:54 | 0:18:56 | |
Well, imagine this is your skin | 0:18:56 | 0:18:58 | |
and there is a hair follicle with a hair growing out of it. | 0:18:58 | 0:19:01 | |
Now every hair follicle has | 0:19:01 | 0:19:03 | |
a sebaceous gland, | 0:19:03 | 0:19:05 | |
which makes a special kind of oil called sebum, | 0:19:05 | 0:19:07 | |
and sebum's good normally, | 0:19:07 | 0:19:09 | |
it keeps your skin moist. | 0:19:09 | 0:19:10 | |
But, during puberty, | 0:19:10 | 0:19:12 | |
sebum levels can skyrocket, | 0:19:12 | 0:19:15 | |
can block up the hair follicle... | 0:19:15 | 0:19:17 | |
..and cause a spot. | 0:19:18 | 0:19:21 | |
Everyone has to put up with the odd spot now and then, | 0:19:21 | 0:19:24 | |
but if it gets really bad, it's called acne. | 0:19:24 | 0:19:27 | |
And if you have acne, there are special clinics on standby to help. | 0:19:27 | 0:19:31 | |
'I'm visiting a special acne clinic | 0:19:33 | 0:19:35 | |
'at Oxford University Hospitals NHS Trust. | 0:19:35 | 0:19:38 | |
'In charge today, | 0:19:40 | 0:19:41 | |
'consultant dermatologist, Tess McPherson.' | 0:19:41 | 0:19:43 | |
What kind of things cause acne? | 0:19:45 | 0:19:47 | |
I think there's lots of myths associated with acne. | 0:19:47 | 0:19:49 | |
It doesn't mean you've got dirty skin. | 0:19:49 | 0:19:51 | |
Other things which people always ask me about is diet, | 0:19:51 | 0:19:54 | |
and there's not much evidence that diet plays a clear role. | 0:19:54 | 0:19:57 | |
If you've had bad acne in the family, | 0:19:57 | 0:19:58 | |
you're more likely to get bad acne yourself, | 0:19:58 | 0:20:00 | |
so, certainly, genetics play a role. | 0:20:00 | 0:20:02 | |
But the main cause is hormones. | 0:20:02 | 0:20:04 | |
This is 15-year-old Josh. | 0:20:04 | 0:20:06 | |
Hard to believe he had bad acne for a couple of years. | 0:20:06 | 0:20:09 | |
I had it all over the face, | 0:20:09 | 0:20:11 | |
the back, the neck, | 0:20:11 | 0:20:13 | |
up the back of the neck, a bit on the chest as well, | 0:20:13 | 0:20:15 | |
it wasn't very nice. | 0:20:15 | 0:20:17 | |
But after seven months of treatment at the clinic | 0:20:17 | 0:20:19 | |
with a tablet that stops the production of sebum, | 0:20:19 | 0:20:21 | |
Josh is doing much better. | 0:20:21 | 0:20:24 | |
Although he does have some left-over scarring on his back. | 0:20:24 | 0:20:27 | |
So was your back probably the most severely affected area? | 0:20:27 | 0:20:29 | |
Oh, yeah, definitely. | 0:20:29 | 0:20:30 | |
So although that scarring does look quite dramatic at the moment, | 0:20:30 | 0:20:33 | |
over time that will fade, and those will end up going. | 0:20:33 | 0:20:35 | |
Some of these ones which are a little bit bumpy | 0:20:35 | 0:20:37 | |
will flatten out over time. | 0:20:37 | 0:20:39 | |
And now I've had the treatment, I'm a lot happier. | 0:20:39 | 0:20:41 | |
As long as it cleared up on my face, I was pretty much happy with that. | 0:20:41 | 0:20:44 | |
So don't worry, scars can fade. | 0:20:44 | 0:20:46 | |
But remember, don't pick. | 0:20:46 | 0:20:47 | |
If you're worried about getting spots when you're a teenager, | 0:20:47 | 0:20:51 | |
then don't panic. | 0:20:51 | 0:20:52 | |
In severe cases like Josh, | 0:20:52 | 0:20:54 | |
doctors can prescribe creams and tablets to help, | 0:20:54 | 0:20:57 | |
but everyone gets some spots, | 0:20:57 | 0:20:59 | |
and here's some tips. | 0:20:59 | 0:21:00 | |
Apart from creams and medicines, | 0:21:00 | 0:21:02 | |
you can help yourself by shampooing your hair regularly, | 0:21:02 | 0:21:05 | |
and avoid letting it fall across your face. | 0:21:05 | 0:21:08 | |
Don't wash affected areas of skin more than twice a day, | 0:21:08 | 0:21:11 | |
and don't pick them. | 0:21:11 | 0:21:12 | |
Now we go back on call, and it's Chris's turn. | 0:21:13 | 0:21:16 | |
Jan, let's go. | 0:21:16 | 0:21:17 | |
Chris, shall we use the car? | 0:21:19 | 0:21:21 | |
So, a call has just come in and it's another mysterious sounding case. | 0:21:25 | 0:21:29 | |
All we know is it's an adult male, | 0:21:29 | 0:21:31 | |
so it literally could be anyone. | 0:21:31 | 0:21:34 | |
A fast response time can be crucial, | 0:21:35 | 0:21:37 | |
especially when you're dealing with... | 0:21:37 | 0:21:38 | |
medical emergencies? | 0:21:38 | 0:21:40 | |
This all looks a bit familiar to me. | 0:21:45 | 0:21:46 | |
He's upstairs. | 0:21:48 | 0:21:50 | |
We better go see him. | 0:21:50 | 0:21:51 | |
HEAVY BASS BOOMS | 0:21:51 | 0:21:53 | |
Let's go see what's going on. | 0:21:53 | 0:21:55 | |
What's that noise? | 0:21:55 | 0:21:56 | |
-MUSIC STOPS -What? | 0:21:59 | 0:22:01 | |
Chris? Jan? | 0:22:01 | 0:22:02 | |
Xand? What's going on? | 0:22:02 | 0:22:04 | |
Well, one minute I feel fine, | 0:22:04 | 0:22:06 | |
and then the next minute I just feel so frustrated and angry | 0:22:06 | 0:22:09 | |
and I just don't... | 0:22:09 | 0:22:10 | |
I'm just in a bad mood. | 0:22:10 | 0:22:13 | |
So you called an ambulance because you're having mood swings? | 0:22:13 | 0:22:15 | |
-Yeah. -Xand, this is not on, you don't call an ambulance | 0:22:15 | 0:22:18 | |
-just because you're having a mood swing. -Sorry, Jan. | 0:22:18 | 0:22:21 | |
Oh, dear, it looks like Dr Xand got a Jan Vann telling-off. | 0:22:23 | 0:22:27 | |
Now, you don't want to be on the receiving end of one of them, | 0:22:27 | 0:22:30 | |
I can tell you. | 0:22:30 | 0:22:31 | |
OK, so, what's been going on? | 0:22:31 | 0:22:33 | |
You know, I don't know whether I'm coming or going, | 0:22:33 | 0:22:35 | |
I mean, one minute I feel fine and then the next minute, | 0:22:35 | 0:22:37 | |
just everything gets me down, like this strawberry milkshake, | 0:22:37 | 0:22:40 | |
I can't get the lid off and they've just put it on really tight | 0:22:40 | 0:22:43 | |
and I can't get it off. | 0:22:43 | 0:22:44 | |
OK, give it here. | 0:22:44 | 0:22:45 | |
There you go. | 0:22:45 | 0:22:46 | |
Thank you. | 0:22:46 | 0:22:47 | |
So what Xand's got is really, really normal during puberty, | 0:22:47 | 0:22:50 | |
he's having a mood swing. | 0:22:50 | 0:22:51 | |
Now, lots and lots of different stuff can set off a mood swing, | 0:22:51 | 0:22:55 | |
but the underlying reason is the same for all of them. | 0:22:55 | 0:22:58 | |
It's to do with changes in hormone levels | 0:22:58 | 0:23:00 | |
that are happening in your body as you grow up. | 0:23:00 | 0:23:03 | |
You need to try and do some sport, | 0:23:03 | 0:23:04 | |
maybe read some books and try and occupy yourself. | 0:23:04 | 0:23:06 | |
-I like sport, I could do some sport, yeah. -You do like sport? | 0:23:06 | 0:23:09 | |
-OK, so do some sport and make yourself feel better. Yeah? -OK. | 0:23:09 | 0:23:12 | |
There are a few different things you can try | 0:23:12 | 0:23:15 | |
if you're having difficulty with your moods. | 0:23:15 | 0:23:17 | |
You can take some time out, you can listen to some music, | 0:23:17 | 0:23:19 | |
you can just do some deep breathing, | 0:23:19 | 0:23:21 | |
but the number one thing is make sure | 0:23:21 | 0:23:23 | |
you ask for help from someone you trust. | 0:23:23 | 0:23:26 | |
So don't worry if you're having mood swings. | 0:23:28 | 0:23:30 | |
The main thing to remember is that there are really some simple | 0:23:30 | 0:23:33 | |
things that you can do about it... | 0:23:33 | 0:23:34 | |
..but calling 999 isn't one of them. | 0:23:36 | 0:23:38 | |
This one's for the girls. | 0:23:41 | 0:23:43 | |
Growing up is fun. | 0:23:44 | 0:23:45 | |
you get to do stuff you've not been allowed to do before. | 0:23:45 | 0:23:48 | |
Whoopee! | 0:23:48 | 0:23:49 | |
Everyone gets a tummy ache occasionally, | 0:23:49 | 0:23:51 | |
but there's another type of tummy ache girls get one day, | 0:23:51 | 0:23:54 | |
when you get your period. | 0:23:54 | 0:23:55 | |
Don't panic, it's completely normal, | 0:23:55 | 0:23:57 | |
and your period will only last a few days each month. | 0:23:57 | 0:24:00 | |
Inside girls' bodies are two organs called ovaries, | 0:24:00 | 0:24:03 | |
which produce eggs. | 0:24:03 | 0:24:05 | |
Eggs are one of the things needed to make a baby when you're an adult. | 0:24:05 | 0:24:08 | |
And in your womb, where a baby grows, | 0:24:08 | 0:24:11 | |
a nice cosy lining gets made each month. | 0:24:11 | 0:24:14 | |
But when there's no baby, | 0:24:14 | 0:24:15 | |
the lining isn't needed and comes out as a bit of blood. | 0:24:15 | 0:24:18 | |
When it happens, tell an adult you can trust. | 0:24:18 | 0:24:21 | |
And if you feel a bit moody, that's normal too. | 0:24:21 | 0:24:24 | |
Just be careful who you bare your teeth to. | 0:24:24 | 0:24:26 | |
Are you finding it hard to sleep? | 0:24:31 | 0:24:33 | |
Finding it even harder to get up? | 0:24:35 | 0:24:36 | |
Are your parents constantly having to nag you to either go to bed | 0:24:38 | 0:24:41 | |
or wake up in the morning? | 0:24:41 | 0:24:42 | |
CHRIS, GET UP! | 0:24:42 | 0:24:43 | |
Well, you've come to the right place. | 0:24:44 | 0:24:46 | |
This is Dr Chris's | 0:24:46 | 0:24:47 | |
one-stop-sleep-shop-clinic-place | 0:24:47 | 0:24:50 | |
for all your sleep-related needs. | 0:24:50 | 0:24:52 | |
Terms and conditions apply. | 0:24:52 | 0:24:53 | |
Monsters under the bed will not be dealt with as a cause of lost sleep. | 0:24:53 | 0:24:56 | |
Offer only applies to die-hard "Operation Ouch!" fans. | 0:24:56 | 0:24:58 | |
Going to bed late and not getting up on time are things | 0:24:58 | 0:25:01 | |
we all do occasionally. | 0:25:01 | 0:25:02 | |
But if you're hitting puberty, | 0:25:02 | 0:25:03 | |
there's actually a scientific explanation. | 0:25:03 | 0:25:05 | |
It's not just laziness, | 0:25:05 | 0:25:07 | |
or not most of the time, | 0:25:07 | 0:25:08 | |
it's all part of becoming an adult. | 0:25:08 | 0:25:10 | |
Now to show you why, I'm going to need some spit, | 0:25:10 | 0:25:13 | |
and some more sleep. Now leave me alone. | 0:25:13 | 0:25:15 | |
These volunteers are going to demonstrate how puberty | 0:25:16 | 0:25:19 | |
changes how you sleep. | 0:25:19 | 0:25:20 | |
Meet Ashleigh and Emma. | 0:25:22 | 0:25:24 | |
They're eight years old | 0:25:24 | 0:25:25 | |
and they're our young sleepers. | 0:25:25 | 0:25:27 | |
This is Thomas, Megan and Alannah. | 0:25:27 | 0:25:30 | |
They're all 13, | 0:25:30 | 0:25:31 | |
they're our teen sleepers. | 0:25:31 | 0:25:33 | |
I'm asking them to collect samples of their saliva every hour | 0:25:33 | 0:25:36 | |
between 4.00pm and when they go to bed. | 0:25:36 | 0:25:38 | |
So, does everyone understand? | 0:25:38 | 0:25:40 | |
ALL: Yes. | 0:25:40 | 0:25:42 | |
We need to spit in these pots. | 0:25:42 | 0:25:43 | |
Yay! | 0:25:43 | 0:25:45 | |
The samples our two groups are taking | 0:25:45 | 0:25:47 | |
will allow me to monitor levels | 0:25:47 | 0:25:49 | |
of a hormone called melatonin. | 0:25:49 | 0:25:51 | |
It's 6.00pm, so I need to spit now. | 0:25:51 | 0:25:53 | |
Melatonin is a hormone your body releases to make you fall asleep | 0:25:53 | 0:25:57 | |
and get some rest. | 0:25:57 | 0:25:58 | |
Goodnight. | 0:25:58 | 0:25:59 | |
I've come to meet neuroscientist Dr Paul Gringras. | 0:26:01 | 0:26:05 | |
He's been analysing our saliva samples for levels of melatonin. | 0:26:05 | 0:26:09 | |
What are the results then, doc? | 0:26:09 | 0:26:11 | |
The younger children, | 0:26:11 | 0:26:12 | |
their melatonin was starting to | 0:26:12 | 0:26:14 | |
be produced about 7.30, | 0:26:14 | 0:26:16 | |
or eight o'clock at the latest. | 0:26:16 | 0:26:18 | |
So that's why if you're younger, | 0:26:18 | 0:26:20 | |
you get tired around this time, | 0:26:20 | 0:26:21 | |
but it changes as you reach puberty. | 0:26:21 | 0:26:24 | |
For the teenage group, | 0:26:24 | 0:26:25 | |
their melatonin was not even being produced till about ten or 11. | 0:26:25 | 0:26:29 | |
And that's why they don't feel tired until much later on. | 0:26:29 | 0:26:33 | |
But you have to be careful because | 0:26:34 | 0:26:35 | |
some things can stop the melatonin doing its job. | 0:26:35 | 0:26:39 | |
We've actually got a body clock that's sensitive to light. | 0:26:39 | 0:26:42 | |
If you start doing things with bright lights, | 0:26:42 | 0:26:45 | |
you are managing to switch off your own melatonin, | 0:26:45 | 0:26:48 | |
which is one of the problems. | 0:26:48 | 0:26:49 | |
So screens like iPads and electronic hi tech stuff | 0:26:49 | 0:26:53 | |
have a lovely bright blue light which keeps us alert, | 0:26:53 | 0:26:56 | |
and in the evening it's about the very worst thing you could do. | 0:26:56 | 0:26:59 | |
So the best thing to do before bed | 0:26:59 | 0:27:01 | |
is to stay away from computer screens. | 0:27:01 | 0:27:04 | |
But because you're going to bed much later than you were before puberty, | 0:27:04 | 0:27:07 | |
and still having to get up at the same time, | 0:27:07 | 0:27:10 | |
that can take some adjusting to. | 0:27:10 | 0:27:12 | |
If you yourself are finding it difficult to wake up, | 0:27:12 | 0:27:14 | |
well, now, you know. | 0:27:14 | 0:27:15 | |
There's a biological reason for it. | 0:27:15 | 0:27:17 | |
You're not just being lazy. | 0:27:17 | 0:27:19 | |
Goodnight. | 0:27:19 | 0:27:20 | |
Although we've not been able to include everything in this puberty | 0:27:26 | 0:27:29 | |
special, hopefully we've covered most of what you wanted to know. | 0:27:29 | 0:27:32 | |
And remember, puberty is totally normal. | 0:27:32 | 0:27:34 | |
It may start earlier for some of you than for others, | 0:27:34 | 0:27:37 | |
-but it happens to everyone in the end. -What? | 0:27:37 | 0:27:40 | |
It's just another phase of growing up. | 0:27:40 | 0:27:42 | |
And preparing you for being an adult. | 0:27:42 | 0:27:44 | |
Which is pretty exciting, really. | 0:27:44 | 0:27:46 | |
And if there is anything you want to know, remember, | 0:27:46 | 0:27:48 | |
you can always ask a parent or a teacher, | 0:27:48 | 0:27:50 | |
they've been through it, too. | 0:27:50 | 0:27:51 | |
Most importantly... | 0:27:51 | 0:27:53 | |
-BOTH: -Don't panic! | 0:27:53 | 0:27:54 | |
ALARM BLARES | 0:27:54 | 0:27:55 | |
Chris, there's an emergency case | 0:27:55 | 0:27:57 | |
of greasy hair in A & E! | 0:27:57 | 0:27:58 | |
Panic stations! | 0:27:58 | 0:28:00 | |
I thought we just agreed not to panic? | 0:28:01 | 0:28:02 | |
You just need that. | 0:28:02 | 0:28:04 |
