00:00Whatever happens, don't look at it.
00:04You're repeating yourself like a mantra.
00:07Your friend is laughing out loud in front of a cat video.
00:10You can't resist the temptation.
00:13Just one look at the screen and you ask for the vehicle to stop.
00:18One of your old travel companions is back.
00:21It's the evil of transportation.
00:24It's been around for centuries.
00:26The famous Greek doctor Hippocrates described the effects of navigation on the body more than 2,000 years ago.
00:33Since the time of Hippocrates, the number of environments in which it is possible to feel this disorder has increased.
00:40Today we can feel the evil of transport by car, by train, on carriages, by plane, by weightlessness in space and even in virtual reality and simulators.
00:51But the real cause of this sensation remains a mystery.
00:54When you are inside a moving car, the interior of the car seems as stable as a rock to you.
01:00But the vestibular system of your inner ear feels the movements.
01:04That's why, even if you travel in total darkness, your body knows that you are moving.
01:09And that's why your senses start to argue to know if you're relaxing or going into space.
01:17Your vestibular system consists of three semicircular tubes and each is responsible for a type of movement.
01:23From top to bottom, from one side to the other and from the front to the back.
01:28There are also two pockets of hair filled with liquid.
01:31When you move, the liquid moves and sends messages to your brain.
01:37This system helps you to perceive the orientation, the speed and the angles of your body.
01:43But if your eyes perceive things that do not correspond to what your ears perceive, then the turbulence begins in your stomach.
01:51And it's not just about moving vehicles.
01:54Even watching a movie, especially a 3D movie, can be at the origin of this phenomenon.
02:01Imagine that the camera on the screen starts to rotate in a circle while you are comfortably seated.
02:06Your eyes will feel like flying and your ears will send opposite signals.
02:11This is when the discomfort occurs.
02:14There is another theory that explains why this happens to some people.
02:18It would be related to posture control.
02:21According to this theory, you suffer from transport discomfort not only because your sensory information is desynchronized,
02:28but also because you can't adjust your posture to reduce this desynchronization.
02:34This seems logical because it is often impossible to get up and straighten your spine in a vehicle,
02:40but we don't have enough evidence to support this idea.
02:43For some people, all this resumes to a feeling of discomfort, while others have to evacuate everything.
02:49And here is another mystery of transport discomfort, since it is related to your eyes and your ears,
02:54why is the stomach concerned?
02:56According to a theory, it would be a matter of evolution.
02:59Fast vehicles are a relatively new concept in terms of evolution.
03:03Our bodies, which are old, were not designed for these sensory roller coasters, and they are still trying to adapt.
03:09Fortunately, the best way to treat a toxic product is to reject it.
03:15Since the dawn of time, the reaction to disorientation caused by a poison is instantaneous purging.
03:21This feeling of disorientation is quite close to transport discomfort.
03:25Thus, when your brain is disoriented by movement, your body decides that it is time to use this good old mechanism of purging.
03:33So it affects us all differently, and there is no explanation for the fact that some people are more prone to this disease than others.
03:42It depends on your general health and the presence of certain affections.
03:46These can affect the way your vision and your balance system work.
03:51We also know that younger people are more likely to use paper bags than their parents.
03:56The type of vehicle you borrow plays an important role in the intensity of the transport discomfort you feel.
04:03The more you are exposed to a chaotic journey and the greater the amplitude of the movements, the more severe the symptoms will be.
04:09If you spend more than eight hours on a small boat during a storm, prepare for a whole symphony of symptoms.
04:15However, if you have to take the train for a journey of a little less than an hour, irregular movements should not turn your trip into a roller coaster.
04:24The role you play during the trip also affects the way you feel.
04:30Many people feel the pain of transport when they are passengers, but not when they are driving.
04:36According to a theory, it all depends on the degree of control you exert on the situation.
04:41As a driver, you are informed in advance of all the turns, and you choose the speed at which you drive them.
04:48You always know when you are about to press the brake and when the car will stop abruptly.
04:53Passengers are like choristers who do not know the song.
04:57They react to each turn, which does not arrange things for them.
05:03This is why a simple solution is to always take the wheel if you know that your body does not like chaotic roads.
05:10If it is impossible, your second best option is to sit right next to the driver.
05:16In this way, you can fix the road in front of you.
05:19Try to keep your eyes on the horizon.
05:23It is your safety line.
05:25When you pass on bumps, the car will move from top to bottom, and your eyes will follow the movement.
05:31There should not be any conflict between your senses, and everything should go well.
05:36If you travel by sea, choose the medium point on a boat.
05:41Except in case of absolute necessity, avoid traveling on a fast boat and opt for a larger and more stable boat.
05:48On a cruise ship, book a cabin in the front or in the middle, closest to the water level.
05:54When you choose a plane seat, opt for the seat next to the window, above the wing.
05:59This is the most stable part of the plane, and even if the flight is chaotic, you will feel little of the effects.
06:05If you go to your destination by train, always choose a seat facing forward, ideally near a window.
06:11In this way, you will be able to contemplate the horizon, make sure to breathe well and moisturize yourself.
06:18If you do not feel well, try to lie down, close your eyes and sleep, if you can.
06:25Check your diet before and during the trip.
06:29Heavy, spicy, strong-smelling and fatty foods can worsen your condition.
06:35In addition, avoid all foods and drinks that do not suit you or that give you an unusual feeling of satiety.
06:43Take for example ginger, a small pinch of ginger powder an hour before departure and every 2 to 4 hours during the trip will help you feel better.
06:53It's easier said than done, but do not think of the harm of transport when you go on a trip.
06:59Research has shown that this is one of the reasons why you can feel bad.
07:04For the same reason, try to avoid the company of people who talk about the harm of transport or who describe feelings of discomfort.
07:12Try to focus immediately on another activity to occupy your brain.
07:17Do not read and do not watch chat videos on the Internet either.
07:21Rather think of your destination and the things you are going to do there.
07:26Tell yourself that you will not be sick this time.
07:29Placebo-verbals have proven to be effective in some cases.
07:33Are you an adept of virtual reality?
07:36If you suffer from this modern type of transport that is called cybercinetosis, try to reduce the duration of your sessions.
07:43Your body should end up adapting to this new reality, but it takes time and training.
07:49Try to choose games where you do not need to move a lot, but where you teleport from one place to another.
07:56A helmet equipped with good lenses will also help you.
07:59You will not need to move your eyes too much and you will feel better in virtual reality.
08:04Finally, make sure to breathe well and make sure that the room is sufficiently ventilated.
