Did you go on a long train or bus journey (旅行)? Did you feel tired during the journey? Have you ever wondered why you feel tired on a long journey, even when you've been sitting the whole time?
Research has found that feeling tired is actually a symptom (症状) of motion sickness (晕动病). Almost everyone will become motion sick. And about one person in three is very sensitive (敏锐的) to motion sickness.
Research has found that while passengers are traveling, their brains (大脑) are working hard to process (加工) the motion of the vehicle (车辆) . And they may feel a mismatch (不协调) between what their feelings are telling them and what their bodies expect to feel. Changes in speed, turning corners, and stopping and starting are motions that our bodies are not really used to, and these can make us feel unwell.
Some people may get sickness faster than others. ____ But it has been found that the longer you travel, the more likely you are to feel sick. Even the activities we do while traveling can have an effect (影响) on how we feel. Passing the time by reading a book or watching a film can create further sensory confusion (感觉困惑) , as our attention is no longer focused on processing the vehicle's motion.
To cut down the effect of motion sickness, you should sit as far forward in a vehicle as possible, there you can feel less motion. You can also get a window seat. And it can also help to close your eyes and sleep.
①Have a sleep.
②Sit at the back of a vehicle.
③Sit in the front of a vehicle.
④Try hard to feel motion sickness.
