"seasickness" の定義と意味

What is "seasickness"?

Seasickness is a type of motion sickness that occurs when on a boat or ship, leading to feelings of nausea and dizziness. It happens because the inner ear, which is responsible for balance, senses movement differently than the eyes, causing confusion in the brain. Symptoms of seasickness include nausea, vomiting, dizziness, sweating, and a general feeling of discomfort. Seasickness can be managed by sitting near the center of a boat where motion is minimized, focusing on the horizon, and taking medications like antihistamines or anti-nausea drugs. It's also helpful to avoid triggers such as reading while in motion.
