Travel Health Untitled Document Travel health Motion sickness Sea sickness, car sickness and air sickness are types of motion sickness. Though children commonly suffer from motion sickness, there is no age limit for feeling queasy while in motion.
Symptoms range from an upset stomach to vomiting.
Motion sickness occurs when conflicting messages are sent to your brain. Normally, your eyes and inner ear work together to communicate motion. But consider the example of reading a book while riding in a car. Although your eyes see little in motion, your inner ear still detects movement. This confuses your brain and makes you feel ill.
