Instructions for handling when suffering from severe motion sickness

Motion sickness is a phenomenon that many people experience to varying degrees, causing great inconvenience to travel. Here are ways to deal with severe motion sickness.

The brain can sense the body's movement by the nervous system, including the inner ear, eyes and body tissues. When the body moves intentionally, such as when walking, the brain controls the actions by synthesizing information about the path being traveled. However, the case of traveling by vehicle will be different. Motion sickness symptoms occur when the central nervous system receives conflicting signals from the sensory systems (including the inner ear, eyes, skin pressure receptors, and joint receptors). . For example, if you are sitting on a boat or in a car (eyes do not look out the window), the inner ear will send signals that the body is moving (up, down, left, right), but the eyes only see the frame. static scene inside the vehicle. Therefore, motion sickness is hypothesized to be caused by a conflict between the signals transmitted to the nervous system.
Any means of transport can cause motion sickness. The symptoms of motion sickness come on suddenly, and range in severity from feeling uncomfortable to breaking out in a cold sweat, dizziness, and vomiting. Motion sickness usually subsides or goes away when the vehicle is no longer moving (although for some people motion sickness can last up to several days). The degree of motion sickness will decrease if the frequency of traveling by means of transport increases (ie, the more vehicles you travel, the more "acquainted", less motion sickness).

To prevent or reduce the level of motion sickness can be done in a few ways:
Choose a seat on the vehicle : choose the seat position on the vehicle is quite important, avoid the seats at the back of the vehicle or Sit facing back to the direction of vehicle movement. Should choose sitting positions for feeling the least movement such as:
On the boat: choose the seat in the middle or at the front of the boat, horizontal close to the water level. On the plane: choose a seat in the middle of the plane, the best position is in front of the front edge of the wing. When the plane takes off, adjust the airflow towards the face. On the train: choose a seat close to the front of the train, face forward compared to the direction of the train moving, and should sit next to the window. On passenger cars: choose a seat near the front of the car. Eyes looking straight ahead, focusing on a stationary object (e.g., looking at the horizon) or looking out into the distance. Avoid reading books, newspapers or using electronic devices while on the go.
