You go to the summer camp on a hot day in a bus full of children jabbering. It is very strange that when you look down, it is down, and not out the window, you have a nausea attack that is quite difficult for you to cope with.
If bus excursions make you feel like this, then you are by no means alone. Astronauts and passengers of the Queen Elizabeth II liner are ill with you.
Do you experience nausea at sea or in a car or on a village cart - all these are manifestations of the same disease, which we, from old memory, will call sea sickness. We are not sick if we walk along the street. Why, sometimes, do we feel so bad if we drive along the same street in a taxi or in a city bus?
Causes of motion sickness
The problem is the difference between what we see and what we feel when we ride in any kind of transport. For example, you are in the cabin of an ocean liner. You experience pitching - you feel that you are rising and falling along with the waves. The fluid in your inner ear moves to the beat and registers it, sending relevant information to the brain.
Interesting fact: motion sickness arises from the contradiction between what you see and what you feel when riding in a moving vehicle.
What happens in the body with motion sickness?
Ears rightly inform the brain that you are moving. However, for your eyes, the cabin remains completely motionless. The eyes send the brain fair and truthful information that you are not moving. The conflicting information coming from the senses, which the brain is used to trust, baffles him. Who to believe?
Stress hormones, such as adrenaline, begin to be released into the bloodstream. Let us say figuratively that adrenaline is a cold sweat of the brain, which is completely at a loss. The muscles of the stomach receive powerful electrical impulses and begin to contract more often and faster than usual. It can end with vomiting. Nine out of ten people have suffered from seasickness at least once in their lives.
Prevention of motion sickness
To minimize the symptoms of this ailment, the following is recommended. While in the bus or car, look out the window at the landscape passing by. Thus, your eyes, and not just the vestibular apparatus, will know that you are moving. Do not read or look at objects inside a moving vehicle.
The best place for you is in front, near the driver, where you can see moving objects in front and on the sides. The same applies to sea voyages. It is much more beneficial for you to be on the deck of an ocean-going vessel than in a closed cabin. In a few days, when the brain understands what is happening, the manifestations of the disease will decrease. The same thing happens on a spaceship.
You can take special medicines against motion sickness.But these medicines can make you drowsy, and sometimes even dizzy and nauseous. You can try “marine bracelets” - elastic bands worn on the forearm. These bracelets use special buttons to press a specific point on the brush. According to the theory of acupressure, clicking on this point reduces nausea. Therefore, these bracelets are recommended to sea travelers and pregnant women if they are concerned about nausea. It seems that these bracelets really help people, although no one knows why.
