If you've ever been sick to your stomach while riding in a car, train, airplane, or boat, you know exactly what motion sickness feels like. It's no fun.
To understand motion sickness, it helps to understand a few parts of your body and how they affect the way you feel movement:
The brain gets an instant report from these different parts of your body and tries to put together a total picture about what you are doing just at that moment. But if any of the pieces of this picture don't match, you can get motion sickness.
For example, if you're riding in a car and reading a book, your inner ears and skin receptors will detect that you are moving forward. However, your eyes are looking at a book that isn't moving, and your muscle receptors are telling your brain that you're sitting still. So the brain gets a little confused. Things may begin to feel a little scrambled inside your head at that point.
When this happens, you might feel really tired, dizzy, or sick to your stomach. Sometimes you might even throw up. And if you're feeling scared or anxious, your motion sickness might get even worse.
To avoid motion sickness:
If you feel this way easily during any kind of movement, it's a good idea to go to the doctor. He or she will want to make sure there's nothing wrong with your inner ears or any of the other body parts that sense movement.
But for typical motion sickness, your parent may be able to give you medicine before you travel. For some kids, it may help to wear pressure bracelets that can be bought at the drugstore.
If you feel yourself getting sick while you're traveling in a car, it might help if the driver finds a safe spot where you can get out and walk around a little bit. If you can't pull over, make sure you have a plastic bag in the car — just in case!
