Guillaume Néry! National record! -
2:18 - 2:19Guillaume Néry: Thank you.

2:19 - 2:22(Applause)
-
2:23 - 2:25Thank you very much,
thanks for the warm welcome. -
2:25 - 2:29That dive you just watched is a journey --
-
2:29 - 2:31a journey between two breaths.
-
2:31 - 2:34A journey that takes place
between two breaths -- -
2:34 - 2:36the last one before diving into the water,
-
2:36 - 2:39and the first one,
coming back to the surface. -
2:39 - 2:44That dive is a journey
to the very limits of human possibility, -
2:44 - 2:46a journey into the unknown.
-
2:46 - 2:50But it's also, and above all,
an inner journey, -
2:50 - 2:52where a number of things happen,
-
2:52 - 2:55physiologically as well as mentally.
-
2:55 - 2:57And that's why I'm here today,
-
2:57 - 3:00to share my journey with you
and to take you along with me. -
3:00 - 3:03So, we start with the last breath.
-
3:04 - 3:07(Breathing in)
-
3:17 - 3:19(Breathing out)
-
3:19 - 3:24As you noticed, that last breath
in is slow, deep and intense. -
3:24 - 3:26It ends with a special technique
called the carp, -
3:26 - 3:30which allows me to store one to two
extra liters of air in my lungs -
3:30 - 3:32by compressing it.
-
3:32 - 3:37When I leave the surface,
I have about 10 liters of air in my lungs. -
3:38 - 3:41As soon as I leave the surface
the first mechanism kicks in: -
3:41 - 3:43the diving reflex.
-
3:43 - 3:47The first thing the diving reflex does
is make your heart rate drop. -
3:47 - 3:50My heart beat will drop
from about 60-70 per minute -
3:50 - 3:52to about 30-40 beats per minute
-
3:52 - 3:55in a matter of seconds;
almost immediately. -
3:55 - 3:58Next, the diving reflex causes
peripheral vasoconstriction, -
3:58 - 4:02which means that the blood flow
will leave the body's extremities -
4:02 - 4:06to feed the most important organs:
-
4:06 - 4:10the lungs, the heart and the brain.
-
4:11 - 4:14This mechanism is innate.
-
4:14 - 4:16I cannot control it.
-
4:16 - 4:18If you go underwater,
even if you've never done it before, -
4:18 - 4:21you'll experience the exact same effects.
-
4:21 - 4:24All human beings
share this characteristic. -
4:24 - 4:26And what's extraordinary
-
4:26 - 4:30is that we share this instinct
with marine mammals -- -
4:30 - 4:34all marine mammals:
dolphins, whales, sea lions, etc. -
4:34 - 4:38When they dive deep into the ocean,
these mechanisms become activated, -
4:38 - 4:40but to a greater extent.
-
4:40 - 4:42And, of course, it works
much better for them. -
4:44 - 4:45It's absolutely fascinating.
-
4:45 - 4:47Right as I leave the surface,
-
4:47 - 4:49nature gives me a push
in the right direction, -
4:49 - 4:52allowing me to descend with confidence.
-
4:52 - 4:54So as I dive deeper into the blue,
-
4:54 - 4:58the pressure slowly starts
to squeeze my lungs. -
4:58 - 5:02And since it's the amount of air
in my lungs that makes me float, -
5:02 - 5:05the farther down I go,
the more pressure there is on my lungs, -
5:05 - 5:08the less air they contain
and the easier it is for my body to fall. -
5:08 - 5:11And at one point,
around 35 or 40 meters down, -
5:11 - 5:14I don't even need to swim.
-
5:14 - 5:19My body is dense and heavy enough
to fall into the depths by itself, -
5:19 - 5:22and I enter what's called
the free fall phase. -
5:22 - 5:25The free fall phase
is the best part of the dive. -
5:25 - 5:27It's the reason I still dive.
-
5:27 - 5:30Because it feels like
you're being pulled down -
5:31 - 5:33and you don't need to do anything.
-
5:33 - 5:37I can go from 35 meters to 123 meters
without making a single movement. -
5:37 - 5:39I let myself be pulled by the depths,
-
5:39 - 5:41and it feels like I'm flying underwater.
-
5:41 - 5:45It's truly an amazing feeling --
an extraordinary feeling of freedom. -
5:45 - 5:48And so I slowly continue
sliding to the bottom. -
5:48 - 5:4940 meters down,
-
5:49 - 5:5150 meters down,
-
5:51 - 5:55and between 50 and 60 meters,
a second physiological response kicks in. -
5:56 - 5:58My lungs reach residual volume,
-
5:58 - 6:03below which they're not supposed
to be compressed, in theory. -
6:03 - 6:07And this second response
is called blood shift, -
6:07 - 6:09or "pulmonary erection" in French.
-
6:10 - 6:12I prefer "blood shift."
-
6:12 - 6:13(Laughter)
-
6:13 - 6:15So blood shift -- how does it work?
-
6:16 - 6:20The capillaries in the lungs
become engorged with blood -- -
6:20 - 6:22which is caused by the suction --
-
6:22 - 6:23so the lungs can harden
-
6:23 - 6:26and protect the whole chest cavity
from being crushed. -
6:26 - 6:30It prevents the two walls
of the lungs from collapsing, -
6:30 - 6:32from sticking together and caving in.
-
6:32 - 6:36Thanks to this phenomenon,
which we also share with marine mammals, -
6:36 - 6:38I'm able to continue with my dive.
-
6:38 - 6:4160, 70 meters down,
I keep falling, faster and faster, -
6:41 - 6:44because the pressure is crushing
my body more and more. -
6:44 - 6:46Below 80 meters,
-
6:46 - 6:48the pressure becomes a lot stronger,
-
6:48 - 6:50and I start to feel it physically.
-
6:50 - 6:52I really start to feel the suffocation.
-
6:53 - 6:55You can see what it looks like --
not pretty at all. -
6:55 - 6:59The diaphragm is completely collapsed,
the rib cage is squeezed in, -
7:00 - 7:02and mentally, there is something
going on as well. -
7:02 - 7:05You may be thinking,
"This doesn't look enjoyable. -
7:05 - 7:06How do you do it?"
-
7:06 - 7:08If I relied on my earthly reflexes --
-
7:08 - 7:12what do we do above water
when there's a problem? -
7:12 - 7:14We resist, we go against it.
-
7:14 - 7:15We fight.
-
7:15 - 7:17Underwater, that doesn't work.
-
7:17 - 7:20If you try that underwater,
you might tear your lungs, -
7:20 - 7:21spit up blood, develop an edema
-
7:21 - 7:24and you'll have to stop diving
for a good amount of time. -
7:24 - 7:27So what you need to do, mentally,
is to tell yourself -
7:27 - 7:30that nature and the elements
are stronger than you. -
7:30 - 7:33And so I let the water crush me.
-
7:33 - 7:36I accept the pressure and go with it.
-
7:36 - 7:39At this point, my body
receives this information, -
7:39 - 7:41and my lungs start relaxing.
-
7:41 - 7:44I relinquish all control,
and relax completely. -
7:44 - 7:48The pressure starts crushing me,
and it doesn't feel bad at all. -
7:48 - 7:51I even feel like
I'm in a cocoon, protected. -
7:51 - 7:54And the dive continues.
-
7:54 - 7:5580, 85 meters down,
-
7:55 - 7:5790,
-
7:57 - 7:58100.
-
7:58 - 8:00100 meters -- the magic number.
-
8:01 - 8:03In every sport, it's a magic number.
-
8:03 - 8:06For swimmers and athletes
and also for us, free divers, -
8:06 - 8:07it's a number everyone dreams of.
-
8:07 - 8:11Everyone wishes one day
to be able to get to 100 meters. -
8:11 - 8:13And it's a symbolic number for us,
-
8:13 - 8:17because in the 1970s,
doctors and physiologists did their math, -
8:17 - 8:22and predicted that the human body
would not be able to go below 100 meters. -
8:22 - 8:25Below that, they said,
the human body would implode. -
8:25 - 8:27And then the Frenchman, Jacques Mayol --
-
8:27 - 8:29you all know him as the hero
in "The Big Blue" -- -
8:29 - 8:32came along and dived down to 100 meters.
-
8:32 - 8:34He even reached 105 meters.
-
8:34 - 8:36At that time, he was doing "no limits."
-
8:36 - 8:39He'd use weights to descend faster
and come back up with a balloon, -
8:39 - 8:41just like in the movie.
-
8:41 - 8:43Today, we go down 200 meters
in no limit free diving. -
8:43 - 8:46I can do 123 meters
by simply using muscle strength. -
8:46 - 8:50And in a way, it's all thanks to him,
because he challenged known facts, -
8:50 - 8:54and with a sweep of his hand,
got rid of the theoretical beliefs -
8:54 - 8:58and all the mental limits
that we like to impose on ourselves. -
8:58 - 9:01He showed us that the human body
has an infinite ability to adapt. -
9:01 - 9:03So I carry on with my dive.
-
9:03 - 9:05105, 110, 115.
-
9:05 - 9:07The bottom is getting closer.
-
9:07 - 9:08120,
-
9:08 - 9:10123 meters.
-
9:10 - 9:11I'm at the bottom.
-
9:11 - 9:15And now, I'd like to ask you to join me
and put yourself in my place. -
9:15 - 9:16Close your eyes.
-
9:17 - 9:20Imagine you get to 123 meters.
-
9:22 - 9:24The surface is far, far away.
-
9:25 - 9:26You're alone.
-
9:28 - 9:30There's hardly any light.
-
9:30 - 9:32It's cold --
-
9:32 - 9:33freezing cold.
-
9:33 - 9:35The pressure is crushing you completely --
-
9:35 - 9:3713 times stronger than on the surface.
-
9:38 - 9:40And I know what you're thinking:
-
9:40 - 9:42"This is horrible.
-
9:42 - 9:44What the hell am I doing here?
-
9:44 - 9:46He's insane."
-
9:46 - 9:48But no.
-
9:48 - 9:50That's not what I think
when I'm down there. -
9:50 - 9:52When I'm at the bottom, I feel good.
-
9:52 - 9:54I get this extraordinary
feeling of well-being. -
9:54 - 9:57Maybe it's because I've completely
released all tensions -
9:57 - 9:59and let myself go.
-
9:59 - 10:02I feel great, without the need to breathe.
-
10:05 - 10:09Although, you'd agree,
I should be worried. -
10:10 - 10:12I feel like a tiny dot,
a little drop of water, -
10:12 - 10:14floating in the middle of the ocean.
-
10:14 - 10:17And each time, I picture the same image.
-
10:18 - 10:20[The Pale Blue Dot]
-
10:20 - 10:23It's that small dot
the arrow is pointing to. -
10:23 - 10:24Do you know what it is?
-
10:25 - 10:27It's planet Earth.
-
10:27 - 10:30Planet Earth, photographed
by the Voyager probe, -
10:30 - 10:32from 4 billion kilometers away.
-
10:32 - 10:36And it shows that our home
is that small dot over there, -
10:36 - 10:38floating in the middle of nothing.
-
10:38 - 10:40That's how I feel
-
10:40 - 10:42when I'm at the bottom, at 123 meters.
-
10:42 - 10:44I feel like a small dot,
-
10:44 - 10:47a speck of dust, stardust,
-
10:47 - 10:49floating in the middle of the cosmos,
-
10:49 - 10:51in the middle of nothing,
in the immensity of space. -
10:51 - 10:53It's a fascinating sensation,
-
10:53 - 10:57because when I look up, down,
left, right, in front, behind, -
10:57 - 11:00I see the same thing:
the infinite deep blue. -
11:00 - 11:03Nowhere else on Earth
you can experience this -- -
11:03 - 11:07looking all around you,
and seeing the same thing. -
11:07 - 11:08It's extraordinary.
-
11:09 - 11:10And at that moment,
-
11:10 - 11:13I still get that feeling each time,
building up inside of me -- -
11:13 - 11:16the feeling of humility.
-
11:17 - 11:20Looking at this picture,
I feel very humble -- -
11:20 - 11:22just like when I'm all the way
down at the bottom -- -
11:22 - 11:24because I'm nothing,
-
11:24 - 11:27I'm a little speck of nothingness
lost in all of time and space. -
11:28 - 11:30And it still is absolutely fascinating.
-
11:31 - 11:34I decide to go back to the surface,
because this is not where I belong. -
11:34 - 11:37I belong up there, on the surface.
-
11:37 - 11:39So I start heading back up.
-
11:40 - 11:44I get something of a shock
-
11:44 - 11:47at the very moment when I decide to go up.
-
11:47 - 11:51First, because it takes a huge effort
to tear yourself away from the bottom. -
11:51 - 11:53It pulled you down on the way in,
-
11:53 - 11:55and will do the same on the way up.
-
11:55 - 11:57You have to swim twice as hard.
-
11:58 - 12:02Then, I'm hit with another
phenomenon known as narcosis. -
12:02 - 12:03I don't know if you've heard of that.
-
12:03 - 12:05It's called nitrogen narcosis.
-
12:05 - 12:08It's something that happens
to scuba divers, -
12:08 - 12:09but it can happen to free divers.
-
12:09 - 12:13It's caused by nitrogen
dissolving in the blood, -
12:13 - 12:15which causes confusion
-
12:15 - 12:17between the conscious
and unconscious mind. -
12:18 - 12:22A flurry of thoughts goes spinning
through your head. -
12:22 - 12:25You can't control them,
and you shouldn't try to -- -
12:25 - 12:27you have to let it happen.
-
12:27 - 12:31The more you try to control it,
the harder it is to manage. -
12:31 - 12:33Then, a third thing happens:
-
12:33 - 12:34the desire to breathe.
-
12:34 - 12:36I'm not a fish, I'm a human being,
-
12:36 - 12:40and the desire to breathe
reminds me of that fact. -
12:40 - 12:42Around 60, 70 meters,
-
12:44 - 12:46you start to feel the need to breathe.
-
12:48 - 12:50And with everything else that's going on,
-
12:50 - 12:53you can very easily lose your ground
-
12:53 - 12:55and start to panic.
-
12:56 - 12:58When that happens, you think,
"Where's the surface? -
12:58 - 13:00I want to go up. I want to breathe now."
-
13:00 - 13:02You should not do that.
-
13:02 - 13:04Never look up to the surface --
-
13:04 - 13:06not with your eyes, or your mind.
-
13:07 - 13:10You should never
picture yourself up there. -
13:10 - 13:12You have to stay in the present.
-
13:12 - 13:16I look at the rope right in front of me,
leading me back to the surface. -
13:17 - 13:19And I focus on that,
on the present moment. -
13:20 - 13:22Because if I think
about the surface, I panic. -
13:22 - 13:24And if I panic, it's over.
-
13:25 - 13:27Time goes faster this way.
-
13:27 - 13:29And at 30 meters: deliverance.
-
13:29 - 13:31I'm not alone any more.
-
13:31 - 13:34The safety divers,
my guardian angels, join me. -
13:34 - 13:36They leave the surface,
we meet at 30 meters, -
13:36 - 13:39and they escort me
for the final few meters, -
13:39 - 13:41where potential problems could arise.
-
13:42 - 13:44Every time I see them, I think to myself,
-
13:45 - 13:47"It's thanks to you."
-
13:47 - 13:49It's thanks to them,
my team, that I'm here. -
13:49 - 13:51It brings back the sense of humility.
-
13:52 - 13:55Without my team, without all
the people around me, -
13:55 - 13:57the adventure into the deep
would be impossible. -
13:57 - 14:01A journey into the deep
is above all a group effort. -
14:01 - 14:04So I'm happy to finish
my journey with them, -
14:04 - 14:06because I wouldn't be here
if it weren't for them. -
14:06 - 14:0820 meters, 10 meters,
-
14:08 - 14:10my lungs slowly return
to their normal volume. -
14:10 - 14:12Buoyancy pushes me up to the surface.
-
14:12 - 14:16Five meters below the surface,
I start to breathe out, -
14:16 - 14:19so that as soon as I get
to the surface all I do is breathe in. -
14:19 - 14:21And so I arrive at the surface.
-
14:22 - 14:24(Breathing in)
-
14:28 - 14:30Air floods into my lungs.
-
14:30 - 14:32It's like being born again, a relief.
-
14:33 - 14:34It feels good.
-
14:34 - 14:36Though the journey was extraordinary,
-
14:36 - 14:40I do need to feel those small
oxygen molecules fueling my body. -
14:40 - 14:44It's an extraordinary sensation,
but at the same time it's traumatizing. -
14:44 - 14:46It's a shock to the system,
as you can you imagine. -
14:46 - 14:49I go from complete darkness
to the light of day, -
14:49 - 14:53from the near-silence of the depths
to the commotion up top. -
14:54 - 14:59In terms of touch, I go from the soft,
velvety feeling of the water, -
14:59 - 15:01to air rubbing across my face.
-
15:01 - 15:04In terms of smell,
-
15:04 - 15:07there is air rushing into my lungs.
-
15:07 - 15:09And in return, my lungs open up.
-
15:09 - 15:12They were completely squashed
just 90 seconds ago, -
15:12 - 15:14and now, they've opened up again.
-
15:14 - 15:17So all of this affects
quite a lot of things. -
15:18 - 15:20I need a few seconds to come back,
-
15:20 - 15:21and to feel "all there" again.
-
15:21 - 15:23But that needs to happen quickly,
-
15:23 - 15:26because the judges are there
to verify my performance; -
15:26 - 15:29I need to show them
I'm in perfect physical condition. -
15:29 - 15:32You saw in the video,
I was doing a so-called exit protocol. -
15:32 - 15:36Once at the surface, I have 15 seconds
to take off my nose clip, -
15:37 - 15:40give this signal and say
(English) "I am OK." -
15:40 - 15:41Plus, you need to be bilingual.
-
15:42 - 15:43(Laughter)
-
15:43 - 15:44On top of everything --
-
15:44 - 15:45that's not very nice.
-
15:47 - 15:51Once the protocol is completed,
the judges show me a white card, -
15:51 - 15:52and that's when the joy starts.
-
15:53 - 15:55I can finally celebrate
what has just happened. -
15:56 - 15:58So, the journey I've just described to you
-
15:58 - 16:01is a more extreme version of free diving.
-
16:02 - 16:04Luckily, it's far from just that.
-
16:04 - 16:05For the past few years,
-
16:05 - 16:08I've been trying to show
another side of free diving, -
16:08 - 16:11because the media mainly talks
about competitions and records. -
16:11 - 16:13But free diving is more than just that.
-
16:13 - 16:15It's about being at ease in the water.
-
16:15 - 16:18It's extremely beautiful,
very poetic and artistic. -
16:18 - 16:20So my wife and I decided to film it
-
16:20 - 16:23and try to show another side of it,
-
16:23 - 16:26mostly to make people want
to go into the water. -
16:26 - 16:31Let me show you some images
to finish my story. -
16:32 - 16:34It's a mix of beautiful underwater photos.
-
16:34 - 16:35(Music)
-
16:35 - 16:40I'd like you to know that if one day
you try to stop breathing, -
16:40 - 16:43you'll realize that
when you stop breathing, -
16:43 - 16:45you stop thinking, too.
-
16:45 - 16:47It calms your mind.
-
16:48 - 16:51Today, in the 21st century,
we're under so much pressure. -
16:51 - 16:54Our minds are overworked,
we think at a million miles an hour, -
16:54 - 16:56we're always stressed.
-
16:56 - 16:59Being able to free dive
lets you, just for a moment, -
16:59 - 17:01relax your mind.
-
17:01 - 17:03Holding your breath underwater
-
17:03 - 17:07means giving yourself the chance
to experience weightlessness. -
17:07 - 17:10It means being underwater, floating,
-
17:10 - 17:14with your body completely relaxed,
letting go of all your tensions. -
17:14 - 17:16This is our plight in the 21st century:
-
17:16 - 17:18our backs hurt, our necks hurt,
everything hurts, -
17:18 - 17:21because we're stressed
and tense all the time. -
17:21 - 17:22But when you're in the water,
-
17:22 - 17:25you let yourself float,
as if you were in space. -
17:25 - 17:27You let yourself go completely.
-
17:27 - 17:28It's an extraordinary feeling.
-
17:28 - 17:34You can finally get in touch
with your body, mind and spirit. -
17:34 - 17:37Everything feels better, all at once.
-
17:38 - 17:42Learning how to free dive is also
about learning to breathe correctly. -
17:43 - 17:47We breathe with our first breath
at birth, up until our last one. -
17:47 - 17:51Breathing gives rhythm to our lives.
-
17:51 - 17:54Learning how to breathe better
is learning how to live better. -
17:55 - 17:58Holding your breath in the sea,
not necessarily at 100 meters, -
17:58 - 17:59but maybe at two or three,
-
17:59 - 18:01putting on your goggles,
a pair of flippers, -
18:01 - 18:03means you can go see another world,
-
18:03 - 18:05another universe, completely magical.
-
18:05 - 18:09You can see little fish, seaweed,
the flora and fauna, -
18:09 - 18:11you can watch it all discreetly,
-
18:11 - 18:14sliding underwater, looking around,
and coming back to the surface, -
18:14 - 18:16leaving no trace.
-
18:16 - 18:20It's an amazing feeling
to become one with nature like that. -
18:21 - 18:24And if I may say one more thing,
-
18:25 - 18:30holding your breath, being in the water,
finding this underwater world -- -
18:30 - 18:32it's all about connecting with yourself.
-
18:32 - 18:36You heard me talk a lot
about the body's memory -
18:37 - 18:40that dates back millions of years,
to our marine origins. -
18:40 - 18:42The day you get back into the water,
-
18:42 - 18:45when you hold your breath
for a few seconds, -
18:45 - 18:48you will reconnect with those origins.
-
18:48 - 18:50And I guarantee
-
18:50 - 18:51it's absolute magic.
-
18:51 - 18:53I encourage you to try it out.
-
18:53 - 18:54Thank you.
-
18:54 - 18:58(Applause)
