Why Do People Get Carsick?

课文

1. Carsickness happens when your eyes, inner ears, and muscles send conflicting signals to your brain.

   晕车是由于眼睛、内耳和肌肉向大脑传递相互矛盾的信号所致。

2. While riding in a car, your eyes may focus on a still book or phone screen.

   乘车时，你的眼睛可能盯着静止的书本或手机屏幕。

3. But your inner ear senses motion as the vehicle speeds up, slows down, or turns.

   但你的内耳却感知到车辆加速、减速或转弯产生的运动。

4. Your body’s sensory mismatch tricks your brain into thinking you might be poisoned.

   这种感官冲突会让大脑误以为身体可能中毒。

5. This triggers nausea, sweating, dizziness, and sometimes vomiting as a defense response.

   从而引发恶心、出汗、头晕，有时还会呕吐，作为防御反应。

6. Children aged 2–12 are especially prone because their balance systems are still developing.

   2至12岁的儿童尤其易发，因为他们的平衡系统尚未发育成熟。

7. Looking out the front window helps match visual input with motion sensed by the inner ear.

   望向正前方车窗有助于让视觉输入与内耳感知的运动保持一致。

8. Taking breaks, breathing fresh air, or chewing ginger can reduce symptoms for many people.

   休息片刻、呼吸新鲜空气或嚼姜可缓解许多人的症状。

9. Medications like dimenhydrinate work by blocking signals between the inner ear and brain.

   苯海拉明等药物通过阻断内耳与大脑之间的信号来起效。

10. Unlike seasickness, carsickness rarely lasts long after the ride ends.

    与晕船不同，晕车通常在下车后很快就会消失。
