As the weather gets warmer, there are few things that are better to do than travel. But traveling might not be that fun for everyone, especially for those who have motion sickness (晕动症).
Motion sickness is also called travel sickness. It is a common experience for many people. Depending on how you travel, it can be called carsickness or seasickness. People with motion sickness feel very uncomfortable while they are in motion. They feel sick and dizzy, like the room around them won't stop spinning (旋转).
It is generally believed that motion sickness happens when your senses become confused (混乱的) with each other. We use different parts of our body to sense movement. Our eyes tell us if we are moving. The inner ears have a special liquid that helps us sense our direction and balance (平衡). Our muscles (肌肉) react to movement. When you move around, these body parts work well together. But when you are in a car or an airplane, they get confused. Your inner ear signals that you're moving, but your eyes say you're sitting still because you can't see that you're moving. This mismatch gives us motion sickness.
About one in three people get motion sickness. Women and children aged two to twelve are most at risk. Some people may even experience motion sickness in certain situations, such as reading in motion, playing video games and watching 3D movies. But some people are. less sensitive to motion sickness. This may be because they have certain genes (基因) that stop mismatching senses.
Although there are many ways to deal with (处理) motion sickness, I believe that the key is to simply try and adapt (适应) to it. For example, some astronauts do special exercises that give them mild (轻微的) motion sickness. After a week or two, the astronauts become used to it and don't feel uncomfortable anymore.
