Seasickness, Airsickness, And Carsickness Explained
Do you find every your sea, air and car ride uncomfortable? Do you get dizzy when you travel or take park rides? You may have motion sickness. Motion sickness is a kind of dizziness which causes a person to have nausea or to vomit. In some instances, even watching moving vehicles or rotating objects makes one feel uncomfortable. Motion sickness has many symptoms aside from nausea and vomiting. It usually starts with getting to swallow saliva, and in most cases yawning and retching. People who have family history of migraine are usually afflicted by this type of sickness and it is often visible when a person starts to sweat and become pale.
Seasickness, airsickness, and carsickness happen only to people who have fully functional inner ear balance systems. This means that people who have both systems in the inner ears are impossible to be seen developing symptoms of motion sickness. In most instances, the most effective remedy for motion sickness is to lie down. By lying down and preventing the body to move, one gets accustomed to the movement and symptoms are then greatly diminished. For people who are prone to this, they usually take oral medications of vestibular suppressants like diphenhydramine or scopolamine and in most cases, symptoms are being prevented from occurring. .
Triggers of motion sickness are excessive motion and sensory mismatch. Excessive motion is usually experienced in a bumpy car ride, or while traveling by boat on rough seas. The body is not used to experiences of unfamiliar changing of speed and accelerations. When boat, for instance, occasionally tilts, or moves up and down, motion sickness is triggered. Also when a car ride requires constant changing of speed on a not so well-paved road, the same sickness is triggered. For people who are already used to long travels, however, seasickness and carsickness are hardly experienced.
Another trigger aside from excessive motion, although closely related to it, is sensory mismatch. This happens when the head feels a moving sensation from what the eyes see. When the body experiences excessive motions, there is a change in visual environment. The inner ears and the eyes, our vestibular sensors, interprets motions and when conflicting information is received, it sends confusing motion to the head. Because of this, the calm movement your eyes see and the tilting movements which your ears interpret during a bumpy ride creates mismatch. This is also true when you are only seeing the motion but you are sitting still and not moving. If any of these situations lasts longer, motion sickness is triggered.
When the above-mentioned causes of seasickness, airsickness or carsickness is controlled, the effect is reduced. One can take oral medications before the ride and some travel with timing. They choose only to travel when the weather is good. For some who knows how to align sensory mismatch, the bumpy rides don’t matter. These people usually position themselves in a place where they can see their surrounding while they travel. They make sure their head maintains a steady movement by staring direct at the horizon in front of them. This is by far observed as effective ways to reduce the mismatch and control the information of the motion which head receives through the ears and the eyes.
