What Causes Seasickness

Introduction


Many people get motion sickness on moving vehicles, whether they be cars, trains or planes. Motion sickness on a boat, otherwise known as sea sickness, is the most common form of motion sickness. Seasickness has prevented many people throughout the world from going on everything from row boats to cruise ships, and it can leave a person miserable when they experience it.


Cause


Seasickness is caused by a conflict between what your body sees or senses, and what your internal body parts feel and sense. When you are on a boat, your inner ear may feel the waves moving the boat, but your other senses, such as sight, may not see what is causing the motion. This causes your eyes and your inner ear to send conflicting messages to your brain on what they are experiencing. Your brain reacts to this conflict by making you feel sick. This sickness will usually continue until the motion stops.


Prevention


According to WebMD, the best prevention techniques for seasickness are getting off the boat, or sitting/lying down in an area of the boat that does not move as much. Many people also try medications to help take some of the nausea away. For boats, the best way to prevent seasickness is to sit on the deck and stare at the horizon, or for cruise ships choose a cabin that is in the most central portion of the ship.
