Motion sickness can happen from any kind of movement, a moving boat, train, airplane, car,etc.
Motion sickness is caused by a conflict between your senses. A fluid filled canal in your inner ear that controls your sense of balance tells your brain that your body is moving, while your eyes tell your brain that you are not moving.
For example, if you are in the cabin of a moving ship, your inner ear may sense the motion of big waves, but your eyes don't see any movement. This leads to a conflict between the senses and results in motion sickness.
The most common signs and symptoms of motion sickness include:
A general feeling of being unwell (malaise)
The following tips can help you prevent or lessen the severity of motion sickness:
Watch your consumption of foods, drinks, and alcohol before and during travel. Avoid excessive alcohol and foods or liquids that "do not agree with you" or make you feel unusually full. Heavy, spicy, or fat-rich foods may worsen motion sickness in some people.
Avoiding strong food odors may also help prevent nausea.
Try to choose a seat where you will experience the least motion. The middle of an airplane over the wing is the calmest area of an airplane. On a ship, those in lower level cabins near the center of a ship generally experience less motion than passengers in higher or outer cabins.
Do not sit facing backwards from your direction of travel.
Sit in the front seat of a car.
Do not read while traveling if you are prone to motion sickness.
When traveling by car or boat, it can sometimes help to keep your gaze fixed on the horizon or on a fixed point.
Open a vent or source of fresh air if possible.
Isolate yourself from others who may be suffering from motion sickness. Hearing others talk about motion sickness or seeing others becoming ill can sometimes make you feel ill yourself.
The over-the-counter medication (Bonine, Antivert, Dramamine) can be a very effective preventive measure for short trips or for mild cases of motion sickness. Your doctor also may choose to prescribe medications for longer trips or if you repeatedly develop severe motion sickness.
