0:00:130:00:16

Our quest for superhumans has brought us to Iceland.

0:00:200:00:23

We're right on the edge of the Arctic Circle!

0:00:230:00:26

It's freezing cold here!

0:00:260:00:28

Today, even in the sun, it's still colder than your freezer at home.

0:00:280:00:35

To survive out here, you'd need the power of a superhero.

0:00:350:00:40

A superhero like Iceman, who never feels cold and uses frost

0:00:420:00:46

and ice to defy evil.

0:00:460:00:48

But I've heard of a real-life iceman!

0:00:500:00:53

A man whose body does not feel the cold.

0:00:530:00:56

A man who cannot be frozen!

0:00:560:00:58

This is Wim Hof.

0:01:030:01:05

He discovered his cold conquering superpowers accidentally,

0:01:050:01:08

over 20 years ago, when he saved a man from a frozen lake.

0:01:080:01:12

Since then, he's astounded scientists around the world with

0:01:120:01:16

his ability to withstand extreme cold, doing so in just his pants.

0:01:160:01:21

And this is him! Wim Hof. I'm so excited to meet you.

0:01:290:01:33

-Hi there.

-Hi.

0:01:330:01:34

Now, tell me, are you a real life iceman?

0:01:340:01:38

That's what they call me! But I am the Iceman, yes.

0:01:380:01:41

Wow! Are you superhuman?

0:01:410:01:44

I'm superhuman because I trained a lot.

0:01:440:01:46

Are you up for three tests, where I'll go up against you,

0:01:460:01:49

I'll be like a human guinea pig

0:01:490:01:51

and we'll see what my body does as opposed to what your body does,

0:01:510:01:54

which is maybe a little bit different?

0:01:540:01:56

I'm always up to a new challenge, so let's do it.

0:01:560:01:59

This is Dr Megan John, she is an expedition doctor

0:02:020:02:05

and has kept people alive in some of the most dangerous environments.

0:02:050:02:09

She's devised three supertests to discover how Tim

0:02:100:02:14

and Wim's bodies react differently.

0:02:140:02:16

So, Dr Megan, I thought we'd be filming up there

0:02:200:02:22

in the mountains with the ice, but you've brought us here to the docks.

0:02:220:02:29

Why are we here?

0:02:290:02:30

For this first experiment,

0:02:300:02:32

I need to be able to control the conditions.

0:02:320:02:34

I've chilled one of these containers to -10 degrees Celsius,

0:02:340:02:37

I'm going to put the two of you in it,

0:02:370:02:39

close the door and see what happens.

0:02:390:02:42

-10!

0:02:420:02:43

Dr Megan will be testing who can stand

0:02:460:02:48

freezing temperatures for the longest.

0:02:480:02:51

This container is about 12 degrees colder than your fridge at home

0:02:510:02:54

and as the test goes on, it will get as cold as a freezer.

0:02:540:02:58

This test is being supervised by medical professionals

0:02:580:03:01

and you should never try anything like this at home.

0:03:010:03:04

It's extremely dangerous.

0:03:040:03:06

This is my control centre for today. I've got some great equipment.

0:03:080:03:11

Firstly, thermal imaging camera.

0:03:110:03:13

It's going to give me some pictures of how the two of your bodies

0:03:130:03:16

are losing heat from the outside.

0:03:160:03:18

Thermal cameras turn heat rays into different colours.

0:03:180:03:22

The white areas are the hottest, red is warm, yellow is cold

0:03:220:03:25

and blue is the coldest.

0:03:250:03:27

Wow! Cool!

0:03:270:03:29

In order for it to be scientifically accurate,

0:03:290:03:32

I need you to do it in your underpants.

0:03:320:03:35

In my pants?

0:03:350:03:36

Yep, in your pants.

0:03:360:03:37

In addition, I want your core body temperature,

0:03:370:03:41

so that's the temperature on the inside of your body.

0:03:410:03:44

How do you manage that?

0:03:440:03:45

Two choices. Either we could put a thermometer up your bottoms...

0:03:450:03:49

Oh, no, don't do that.

0:03:490:03:51

But I've decided we'll go a bit high tech today so I've got these

0:03:510:03:54

core body transmitters, which I'd like you to swallow.

0:03:540:03:57

So how does that work?

0:03:570:03:58

It transmits the temperature to you on the outside?

0:03:580:04:01

Exactly, I've got a reader here.

0:04:010:04:03

That really is not nice. Don't try anything like this at home.

0:04:070:04:11

So, chamber set for -10?

0:04:110:04:13

OK, boys, kits off, ready to go!

0:04:150:04:18

Let's go!

0:04:180:04:20

-10 in my pants.

0:04:200:04:22

The normal human temperature is 37 degrees Celsius.

0:04:240:04:27

If your body gets colder than that you get goosebumps

0:04:270:04:31

and start to shiver.

0:04:310:04:32

If you drop to 35 degrees, you are dangerously cold

0:04:320:04:35

and we call this hypothermia.

0:04:350:04:38

You start to move slowly, your fingers, toes and lips go blue.

0:04:380:04:42

Soon, you need to wee.

0:04:420:04:44

Then your brain becomes confused.

0:04:440:04:47

Eventually, your kidneys, liver, lungs and heart

0:04:470:04:49

may shut down and you could die.

0:04:490:04:52

If at any point I think your health is in danger,

0:04:560:04:59

I'm going to pull you out.

0:04:590:05:01

Three. Two. One. Head in.

0:05:010:05:06

It really is quite cold.

0:05:090:05:11

So already they'll be going into feeling a little bit shocked

0:05:110:05:14

first of all.

0:05:140:05:16

Dr Megan has given them a few simple games to play, but not for fun.

0:05:160:05:21

-Snowball?

-Exactly right! A snowball.

0:05:210:05:24

Being dangerously cold affects the brain as well as the body,

0:05:240:05:28

so if Tim and Wim become confused playing these games,

0:05:280:05:32

Dr Megan will know it's time to get them out!

0:05:320:05:34

I don't know if you can see this on the TimCam

0:05:360:05:39

but my skin's gone all goose bumps. I've got a lot of goosebumps here.

0:05:390:05:42

Goosebumps are made when small muscles in your skin tighten up,

0:05:420:05:47

making your hairs stand on end.

0:05:470:05:49

This is because thousands of years ago, people were a lot hairier,

0:05:490:05:54

so when their hair stood on end, it trapped the heat next

0:05:540:05:57

to their skin, keeping them warm, a bit like wearing a jumper.

0:05:570:06:02

And after ten minutes, Tim's body is covered in goosebumps,

0:06:020:06:06

but Wim doesn't have any.

0:06:060:06:08

This is a thing that swims through really cold water. Like you.

0:06:080:06:12

Wim just looks completely comfortable,

0:06:120:06:14

like he's sat in his living room watching the telly.

0:06:140:06:17

-A seal.

-A seal! That's right, he knows that, there we go.

0:06:170:06:21

Oh, wow! OK, let's keep going.

0:06:210:06:24

Tim really is starting to feel the cold now.

0:06:240:06:26

He's shivering, he's rubbing all his muscles together.

0:06:260:06:29

He's what we call tremulous,

0:06:290:06:30

so very, very light little shakes all over his body.

0:06:300:06:33

15 minutes in and the temperature in the cold room has

0:06:330:06:36

gone down to -11.5 degrees.

0:06:360:06:40

Oh, wow. Got a lot of goosebumps now.

0:06:400:06:43

And slightly shivering.

0:06:430:06:47

Everything in Tim's body right now

0:06:470:06:49

is trying to launch an attack on the cold.

0:06:490:06:51

His body is saying, "I don't like this, get me out of it."

0:06:510:06:55

Wim is not shivering, he's not moving, he's not confused.

0:06:550:06:59

He's not really doing any of the things

0:06:590:07:02

I would expect a normal human to do.

0:07:020:07:04

I seem to have a pain in my back. Not on my back, but inside.

0:07:040:07:08

He's just done something really classic, rubbing the area

0:07:080:07:11

on his lower back, which is where the kidneys are.

0:07:110:07:14

As you get really cold, you end up getting to the point

0:07:140:07:17

where you wet yourself.

0:07:170:07:18

In freezing cold like this, your heart has to work much harder

0:07:200:07:23

to pump blood around your body.

0:07:230:07:26

Now, to make it easier, your body gets

0:07:260:07:29

rid of things in your blood that it doesn't need, like excess water.

0:07:290:07:33

Now, your kidneys do this.

0:07:330:07:35

There are two of them. They're about the size of a mobile phone.

0:07:350:07:39

The unwanted water in your blood turns into wee.

0:07:390:07:43

All this extra work your kidneys are doing makes them really ache.

0:07:430:07:47

25 minutes into the test and it's -12 degrees!

0:07:490:07:54

It's so cold that Tim's heart can not provide enough warm blood

0:07:540:07:57

to his whole body.

0:07:570:07:59

Most of his blood is being sent to his important inner organs.

0:07:590:08:02

So the outer parts of his body aren't getting much blood at all.

0:08:020:08:07

My knuckles have gone slightly blue here.

0:08:070:08:10

Yeah, the knuckles have gone blue.

0:08:100:08:12

In fact, my hand's gone blue.

0:08:120:08:14

Wim, how you feeling? You shivering a bit with the goosebumps?

0:08:140:08:17

Yeah.

0:08:170:08:19

Even Wim has started to get goosebumps now.

0:08:190:08:22

I don't have to pull him out just yet.

0:08:220:08:24

So after 28 minutes and with the cold room at -12 degrees,

0:08:240:08:29

goosebumps have appeared on Wim.

0:08:290:08:31

This is a whole 23 minutes,

0:08:310:08:33

and 2 degrees colder than when they appeared on Tim.

0:08:330:08:36

Tim, how are you feeling?

0:08:360:08:39

Freezing cold, Dr Megan.

0:08:390:08:41

Tim's brain is now so cold

0:08:410:08:44

he is losing the ability to think properly.

0:08:440:08:47

What have you done?

0:08:470:08:48

It's a definite sign of hypothermia.

0:08:480:08:51

INDISTINCT CHAT

0:08:510:08:53

Why did you do that?

0:08:570:08:58

Checking their core body temperatures.

0:08:580:09:01

So it's 643.

0:09:010:09:02

The average human body temperature is 37 degrees,

0:09:030:09:07

and after over 30 minutes with the temperature lower than -12 degrees,

0:09:070:09:11

Wim's core temperature has dropped by only half a degree.

0:09:110:09:16

Mine...

0:09:160:09:17

Tim, tell me how you're feeling.

0:09:190:09:21

Very cold now. Very, very cold indeed.

0:09:210:09:24

I'm down just below 35.

0:09:240:09:27

Tim's body temperature has dropped by more than 2 degrees, this means

0:09:270:09:32

it's now under 35 degrees and he's starting to suffer from hypothermia.

0:09:320:09:36

His body can't take much more.

0:09:360:09:39

Honestly, I'm probably going to pull him quite soon.

0:09:400:09:43

Cos he's in pain everywhere.

0:09:430:09:45

Come on, people, I can do this.

0:09:450:09:47

OK, so Tim is now in so much pain, I don't think it's safe for him

0:09:470:09:52

to continue any more, so I want him out.

0:09:520:09:55

Boys, can you get him out?

0:09:550:09:57

Tim, Tim, you need to get out now.

0:09:570:10:00

-Get out.

-I shall finish this in the warmth. Ah!

0:10:000:10:07

It's too dangerous for Tim to carry on. He's turning blue and there's

0:10:070:10:11

so little blood going to his arms and legs that he can't even walk.

0:10:110:10:15

Can we get him in the hot bath now?

0:10:150:10:17

After 37 minutes and 13 seconds in this freezing room,

0:10:170:10:22

Tim stumbles into the recovery bath, he's in pain and he's very confused.

0:10:220:10:27

It's on fire! Like internally on fire, guys.

0:10:270:10:30

-That's a bit of fun, isn't it?

-This is a lukewarm bath.

0:10:300:10:34

-It's not as warm as you'd have at home.

-It's really, really hot!

0:10:340:10:37

But unbelievably, Wim is still in the cold room.

0:10:370:10:41

And now he's doing yoga?!

0:10:410:10:43

So, clearly, Wim, having already been in there for the ten minutes

0:10:430:10:46

it's taken to get Tim out of there and into the bath,

0:10:460:10:49

Wim is stood up, holding himself.

0:10:490:10:51

I think the experiment has reached its conclusion,

0:10:510:10:54

which is that Wim has some super powers,

0:10:540:10:56

which Tim, a normal human being, does not have.

0:10:560:10:59

So I'd like to call an end to the experiment

0:10:590:11:01

and get Wim out of there too.

0:11:010:11:03

Wim still has an ordinary body temperature of 36.5 degrees

0:11:030:11:07

after 40 minutes of extraordinarily freezing cold!

0:11:070:11:12

You see how perfectly you walked out, Wim. How are you feeling?

0:11:120:11:15

-OK.

-You've got ice cubes around your beard.

0:11:150:11:19

So how is Wim able to do this?

0:11:190:11:22

It seems he can control his body temperature.

0:11:220:11:25

Now, there is a part of your brain called the hypothalamus

0:11:250:11:28

and its job is to keep your body at 37 degrees.

0:11:280:11:32

It's about the size of a peanut.

0:11:320:11:34

Your hypothalamus works automatically.

0:11:340:11:36

You cannot control it or override it.

0:11:360:11:39

What's amazing is that Wim can control his hypothalamus

0:11:390:11:43

and can make himself hotter if he wants to.

0:11:430:11:46

So before he went into the tank,

0:11:460:11:48

he turned his temperature up to 39 degrees.

0:11:480:11:51

We're here on the Vatnajokull Glacier.

0:11:540:11:58

The ice can get as much as 1,000 metres thick.

0:11:580:12:02

And it gets cold, very, very cold!

0:12:020:12:06

But luckily, people are amazingly, fantastically adaptable.

0:12:060:12:11

Especially the Kallallit people from Greenland.

0:12:110:12:14

They have more blood cells than people from warmer areas,

0:12:140:12:17

which generates more heat, and their bodies are small and bulky,

0:12:170:12:21

which is the best shape to protect you from the cold.

0:12:210:12:25

They eat loads of fat, from food like seal blubber,

0:12:250:12:28

which their bodies then burn, to create heat and keep them warm.

0:12:280:12:32

In supertest two, Dr Megan is testing Wim

0:12:400:12:43

and Tim's ability to stay warm whilst exercising in the cold.

0:12:430:12:46

She has marked out a course on the largest ice cap in Europe

0:12:460:12:50

and she wants to see who can run for the longest.

0:12:500:12:53

The weather changes in an instant here, from sunlight to blizzards,

0:12:530:12:56

but it's always very cold.

0:12:560:12:59

OK, so this is the course?

0:12:590:13:01

Yep, I've marked out a 1 kilometre course with these flags and I'd

0:13:010:13:04

like the two of you to try and do it in just your shorts, barefoot.

0:13:040:13:08

-Barefoot?

-Barefoot.

-I'm absolutely loving this.

0:13:080:13:12

I might get frostbite, this is seriously cold.

0:13:120:13:14

That is a danger here today, which is why I'll be monitoring

0:13:140:13:17

your core body temperature, your heart rate, talking to you and I've

0:13:170:13:21

brought a safety vehicle here with me, with a search and rescue team.

0:13:210:13:24

OK, I feel a bit reassured now.

0:13:240:13:26

Everybody's body is different but an average, fit adult would normally

0:13:260:13:30

have a heart rate during exercise of around 120 beats per minute.

0:13:300:13:35

But running in the freezing cold puts extra stress on your body.

0:13:350:13:38

You're more likely to damage a muscle.

0:13:400:13:43

With no shoes, you could freeze your toes and get frostbite.

0:13:430:13:46

You use up oxygen much more quickly,

0:13:460:13:48

and could become confused, or even faint.

0:13:480:13:50

Your heart beats faster

0:13:500:13:52

and if you reach your maximum heart rate, you could collapse.

0:13:520:13:55

In extreme cases, you could have a heart attack and you could die.

0:13:550:13:59

You seem really relaxed about this. You're ready to go.

0:14:010:14:03

What have you done? What's the secret?

0:14:030:14:06

I trained a lot and to connect the mind with the body.

0:14:060:14:09

And how do you do that?

0:14:090:14:11

Sort of a meditation, going deeper within yourself

0:14:110:14:14

and reawaken the natural ability to cope with cold.

0:14:140:14:19

So do you think that before we do the test you could teach me that,

0:14:190:14:22

at least a little bit?

0:14:220:14:24

I will give the principles, but you've got to build the house.

0:14:240:14:27

OK. Let's try it.

0:14:270:14:29

Meditation is a way of focusing your mind

0:14:310:14:33

by using special breathing and concentration.

0:14:330:14:37

Make yourself as light as possible.

0:14:370:14:39

You need to try and reconnect with your body.

0:14:390:14:42

You should only try meditating if you're with an expert

0:14:420:14:45

and Wim has trained for over 20 years.

0:14:450:14:48

Totally in. Totally out. Once again. Totally in. Totally out.

0:14:480:14:52

Our thermal camera image shows that

0:14:520:14:55

Wim's body temperature is beginning to rise.

0:14:550:14:58

And the same thing is happening to Tim.

0:14:580:15:00

It's really interesting to see that despite the fact

0:15:010:15:04

that it's 0 degrees, Tim's starting to sweat

0:15:040:15:07

Tim's core body temperature, which started at 37 degrees, is going up.

0:15:080:15:13

So fascinatingly, he's gone up by nearly a degree, to 38.18.

0:15:130:15:17

What's your heart rate doing at the moment?

0:15:170:15:19

Still running at around 72.

0:15:190:15:21

So you've brought it down a little bit from before.

0:15:210:15:25

OK, so 41.47. So whenever you're ready, Wim. 62.

0:15:250:15:31

They're ready to go.

0:15:310:15:33

Are you good? Let's do this now.

0:15:330:15:37

Let's go.

0:15:370:15:38

Normally, Tim's heart rate when he's running is 121 beats per minute,

0:15:400:15:45

but in these freezing conditions, it's beating a lot faster.

0:15:450:15:49

Heart rate is now at 167.

0:15:490:15:53

Wim, can you let me know your heart rate?

0:15:530:15:56

82.

0:15:560:15:57

82. So we've got a heart rate of 82. Tim's is nearly double.

0:15:570:16:01

Blood carries oxygen and sugars round the body.

0:16:030:16:06

When you exercise, you use more oxygen and sugar

0:16:060:16:10

so your heart needs to pump faster.

0:16:100:16:12

Now, when you're cold, your body needs more oxygen and sugar too.

0:16:120:16:16

That also makes your heart pump faster.

0:16:160:16:19

So when you run in the freezing cold, your heart has to pump

0:16:190:16:22

extremely hard to keep you moving and keep you warm.

0:16:220:16:26

Running on the ice in the coldest glacier in Europe.

0:16:280:16:33

It's the 250 metre mark.

0:16:330:16:35

We've gone past the first flag.

0:16:350:16:37

Tim is starting to struggle

0:16:370:16:39

but Wim is fine, he's conserving his energy and pacing himself.

0:16:390:16:43

Wim's heart rate is going at 82 beats per minute,

0:16:430:16:46

a very normal response to exercise.

0:16:460:16:48

Tim's heart's under an awful lot of pressure.

0:16:490:16:52

Coming down the hill now. Down the hill.

0:16:520:16:55

Tim, what's your heart rate now?

0:16:550:16:56

Heart rate is up at 178.

0:16:560:16:58

84.

0:16:580:17:01

Wim's heart rate is incredibly low at only 84 beats per minute,

0:17:010:17:05

ut Tim's is now 178. This is dangerously fast.

0:17:050:17:10

This is getting touch and go as to whether I can let them

0:17:100:17:13

go on any more. Boys, if you could just stop

0:17:130:17:15

so I can check your core body temperature before you carry on.

0:17:150:17:19

HE PANTS

0:17:190:17:21

I want you to look at my feet.

0:17:220:17:24

In extreme cold, your body must keep your vital organs warm

0:17:240:17:28

to keep you alive.

0:17:280:17:30

This means that your body concentrates on getting

0:17:300:17:33

nice warm blood to these bits.

0:17:330:17:35

Other less important bits, like your fingers and toes,

0:17:350:17:38

they get less blood.

0:17:380:17:39

With less blood keeping them warm, these bits start to feel numb,

0:17:390:17:43

then they start to freeze.

0:17:430:17:45

The skin on them blisters turns black.

0:17:450:17:48

Eventually, they can die and drop off.

0:17:480:17:52

Tim's numb feet are an early warning sign of frostbite.

0:17:520:17:57

So you're going, you're still going at 37.5.

0:17:570:18:00

This is extraordinary. I did not think this would be possible at all.

0:18:020:18:06

I'm amazed that he's carried this far

0:18:060:18:08

but I'm starting to get very worried about Tim's general health.

0:18:080:18:11

His heart rate is going nearly three times

0:18:110:18:13

what I would be comfortable with.

0:18:130:18:15

They've passed the 750 metre mark.

0:18:150:18:18

Tim is uncoordinated, confused and his heart rate is critically high,

0:18:180:18:22

while Wim's body condition, well, it's has hardly changed at all.

0:18:220:18:26

Now, I think, interestingly,

0:18:260:18:28

purposability determination's kicked in.

0:18:280:18:31

One of the signs of hypothermia is confusion

0:18:310:18:33

and Tim is starting to exhibit a little bit of confusion.

0:18:330:18:36

He thinks he can manage more than he can.

0:18:360:18:38

What normally happens with people when they get very cold

0:18:380:18:41

is the thing they die of is doing more than they should

0:18:410:18:43

because they start to get fighty and aggressive.

0:18:430:18:46

But this is absolutely more than I ever hoped or dreamed of

0:18:460:18:49

being able to do. In bare feet. Across a glacier.

0:18:490:18:53

Can I have your heart rates now?

0:18:530:18:55

-It's now at 184.

-92.

0:18:550:18:57

Wow. Coming up to 1,000 metres Wim's heart rate is unbelievably low.

0:18:570:19:02

But Tim's has now moved into a critical state,

0:19:020:19:05

his heart really can't take much more of this.

0:19:050:19:09

I'm using every single molecule of energy to make it to those flags.

0:19:090:19:14

I've got pain in my feet.

0:19:150:19:17

Tim, I don't think it's safe for you to continue.

0:19:170:19:20

HE PANTS

0:19:220:19:23

Tim's finished the race, but in doing so

0:19:260:19:29

has put himself in serious danger.

0:19:290:19:31

Dr Megan and the team have to cover him in insulating materials to

0:19:310:19:35

keep him warm as blood starts to return to his outer body.

0:19:350:19:39

I'm trying to keep his head lower than his heart

0:19:390:19:42

so that the blood supply gets back to his heart.

0:19:420:19:44

I'm trying to feed him some sugar, cos you get a rapid reduction

0:19:440:19:47

in sugar when you do so much exercise.

0:19:470:19:49

The rest of me feels OK, it's just the feet.

0:19:490:19:52

I can't move them now.

0:19:520:19:53

It'll be painful for Tim all over, but especially in his feet.

0:19:530:19:57

Tim needs to get off the mountain and into a recovery bath fast!

0:19:590:20:03

But remarkably, Wim is completely fine!

0:20:030:20:07

So right now, do you feel in control of your heart rate?

0:20:070:20:09

-Yeah.

-In control of your body temperature?

-Yes.

0:20:090:20:12

-You don't feel unwell in any way?

-No.

-You don't feel sick?

0:20:120:20:15

-No.

-No pain anywhere in your body?

-Nothing.

0:20:150:20:18

Remarkable. Quite remarkable.

0:20:180:20:20

OK. We've just come off the mountain now.

0:20:200:20:23

Dr Megan's looked at my feet and it seems I might have frostbite

0:20:230:20:26

so they're taking me back to the hotel

0:20:260:20:28

to get some sort of warming bath on them.

0:20:280:20:31

It'll be painful, but my feet will return to normal.

0:20:320:20:35

Sometimes the human body has an amazing ability to recover.

0:20:350:20:39

In 1999, Swedish Skier Anne Bagenholm fell

0:20:390:20:43

headfirst into a frozen water and was trapped under the ice.

0:20:430:20:47

Luckily, she found an air pocket and was able to breath but eventually

0:20:470:20:51

she got so cold, extreme hypothermia actually stopped her heart!

0:20:510:20:56

When she was cut out of the ice,

0:20:560:20:58

Anne's heart had stopped for 80 minutes.

0:20:580:21:02

Her body temperature was so cold that she should have been dead.

0:21:020:21:06

Amazingly, as Anne's body slowly warmed up,

0:21:060:21:10

signs of life began to show.

0:21:100:21:11

And incredibly, ten days later, she was brought fully back to life.

0:21:110:21:16

Anne now works as a doctor in the hospital that saved her life.

0:21:160:21:21

In the third and final supertest, Dr Megan wants to see

0:21:290:21:33

how their bodies react in cold water.

0:21:330:21:35

She's set up a 300 metre swim in a freezing Arctic lake.

0:21:350:21:40

This swim is so dangerous, we have a specialist safety crew on standby.

0:21:400:21:45

Wim, with his extraordinary super powers, tells me that he

0:21:450:21:49

can swim in his swimming trunks for approximately ten minutes.

0:21:490:21:53

-In your trunks?

-Don't be mistaken, it needs a lot of trainings.

0:21:530:21:56

Otherwise, hypothermia's a real threat to the health.

0:21:560:22:00

I'd imagine it's a fatal threat to the health.

0:22:000:22:02

So we have to do this controlled,

0:22:020:22:04

but then this experiment is an adventure.

0:22:040:22:07

And we're thinking you'll give that a go as well

0:22:070:22:09

so we can test your body.

0:22:090:22:11

I'm going to try the swimming in my shorts with the icebergs?

0:22:110:22:14

-Tim, I will make sure you don't come to any harm.

-That's reassuring.

0:22:140:22:18

And I am there too. I am the Iceman.

0:22:180:22:20

You're the Iceman, that's right, you are.

0:22:200:22:23

And I'm a man who needs to get into some swimming trunks.

0:22:230:22:26

Freezing cold water is extremely dangerous because

0:22:260:22:29

it takes away heat from your body 15 times quicker than air.

0:22:290:22:33

When swimming in icy water, your muscles get cold so quickly

0:22:330:22:37

that they stop working, which means you can't swim,

0:22:370:22:40

which means you can drown.

0:22:400:22:42

The freezing temperature can also cause your body to go into shock.

0:22:420:22:46

And you could suffer a heart attack and die.

0:22:460:22:48

This is incredibly dangerous.

0:22:490:22:51

If you do have a glacial lagoon in your back garden,

0:22:510:22:54

do not try this at home.

0:22:540:22:56

And even if you haven't, don't try this in any freezing water.

0:22:560:23:00

-OK, shall we do this?

-Yes.

0:23:000:23:03

-Good luck, Tim.

-Right, I'm going to try my best.

0:23:030:23:06

It's got icebergs in!

0:23:070:23:09

Oh, that's cold. That's really quite cold!

0:23:160:23:19

-Tell me what your heart rate's doing, Tim.

-110.

-And Wim?

0:23:190:23:23

-72.

-72? Brilliant. Well done.

0:23:230:23:26

-Good grief, that's cold!

-How are your feet feeling, Tim?

0:23:260:23:30

They're very, very cold. Very cold. I've got goosebumps.

0:23:300:23:35

Gosh, this is cold! This is really cold.

0:23:380:23:40

You're already starting to show a lot of stress from the cold.

0:23:400:23:43

-I'm really shivering below more than above.

-More than above?

0:23:430:23:46

There's a lot of pain in my ankles and my knees.

0:23:460:23:49

Do you feel able to take another step?

0:23:490:23:52

I could probably take one more.

0:23:520:23:54

OK, tell me what your heart rate's doing now.

0:23:580:24:01

-It's gone up. It's up at 114.

-And Wim?

0:24:010:24:05

-62.

-OK, Tim, I think this is getting potentially

0:24:050:24:09

a little bit too dangerous. Putting too much strain on your heart.

0:24:090:24:13

-Can you come on out and get in the bath now?

-Yeah.

0:24:130:24:15

Yeah, I'm coming.

0:24:150:24:17

That was really cold.

0:24:230:24:26

What's really strange is,

0:24:260:24:28

I completely lost the feeling in my feet.

0:24:280:24:30

To swim safely in freezing water,

0:24:300:24:33

you'd need a specialised semi-dry wet suit made from 7mm thick rubber.

0:24:330:24:38

Tim may not be superhuman but at least he has a cool suit!

0:24:390:24:42

Wim, let's do this! Let me just get this right.

0:24:440:24:48

Even in the super suit, there are still some risks?

0:24:480:24:53

Yes, this is still potentially very dangerous.

0:24:530:24:56

-OK, boys, off you go.

-Good luck, Wim.

-Good luck.

0:24:560:25:00

Wow.

0:25:000:25:02

Wim is going in fast.

0:25:020:25:05

-Are you ready?

-I'm totally ready.

0:25:050:25:08

I'm going "Wimming". This is swimming with Wim.

0:25:080:25:12

It's the moment of truth, Wim is going to attempt

0:25:120:25:15

a 300 metre swim in freezing cold water.

0:25:150:25:19

A normal human being could suffer deadly body shock

0:25:190:25:22

in water this cold.

0:25:220:25:23

Wim should not be able to submerge his body in this

0:25:230:25:26

without seriously risking his health.

0:25:260:25:29

I can't believe what Wim is doing.

0:25:300:25:32

He's rewriting all the text books. It's truly amazing.

0:25:320:25:36

Wim is looking entirely comfortable,

0:25:380:25:40

as if he was swimming in his local swimming pool.

0:25:400:25:42

How are you feeling, Wim?

0:25:440:25:45

OK. In control. It's beautiful!

0:25:450:25:49

He's not really displaying any signs of being incredibly cold.

0:25:490:25:54

This is just remarkable. We've got an iceberg right behind Wim.

0:25:540:25:57

Wim, how are you feeling?

0:25:580:26:01

-I feel great.

-You feel great?

-Yeah.

0:26:010:26:03

Boys, you're now halfway. five minutes in.

0:26:030:26:07

You're feeling absolutely fine?

0:26:070:26:09

-I'm totally OK.

-You genuinely feel OK?

0:26:090:26:11

Yeah, really.

0:26:110:26:12

In this freezing cold water,

0:26:120:26:14

I would expect to be pulling him out because his heart had

0:26:140:26:17

gone into such funny rhythms that we were at risk of him dying.

0:26:170:26:20

When you know how to deal with the cold,

0:26:200:26:23

the cold will make you stronger. That's it.

0:26:230:26:26

Boys, can you start coming back towards me?

0:26:260:26:28

We're eight minutes in now.

0:26:280:26:30

I can still feel how cold the water is,

0:26:300:26:32

-even when it comes into the wet suit.

-OK.

0:26:320:26:34

-It's quite amazing.

-Cold is a force.

0:26:340:26:36

There's no possibility that he should still be swimming, chatting.

0:26:360:26:40

It's remarkable.

0:26:400:26:42

After ten minutes, Wim Hof has achieved the impossible.

0:26:420:26:46

He's survived a swim in a freezing glacial lake

0:26:460:26:49

that should be fatal to any normal human being.

0:26:490:26:51

Look at this.

0:26:520:26:54

You've got goosebumps though. You do have goosebumps!

0:26:540:26:57

Oh, no. You don't have goosebumps.

0:26:570:26:59

That was extraordinary.

0:27:020:27:04

Well done.

0:27:040:27:06

INDISTINCT CHAT

0:27:060:27:08

OK, you've seen it here.

0:27:080:27:10

We've been out in a glacial lagoon in just above freezing temperature.

0:27:100:27:15

I've had to put on this unbelievable wet suit

0:27:150:27:17

to try and get out there with Wim.

0:27:170:27:19

Wim has been out just in his swimming trunks and he shows no visible

0:27:190:27:23

signs of cold, no visible signs of any medical problem at all.

0:27:230:27:27

This is absolutely extraordinary.

0:27:270:27:29

I came to Iceland to find a superhero.

0:27:290:27:33

A real life Iceman, a man who doesn't feel the cold.

0:27:330:27:37

I found one. Wim Hof, you are superhuman!
