Travel sickness is also commonly known as motion sickness. It occurs when repetitive small movements means that the brain is sent mixed messages, with the eyes saying one thing and the balance mechanisms of the ear saying another. However, smells, anxiety, or focusing on a nearby object such as a book can also trigger travel sickness. Symptoms include dizziness, nausea, vomiting, drowsiness, headache, sweating and pallor. Treatment options include ginger, peppermint, anti-nausea medications, acupressure, keeping still, not reading, increasing ventilation, avoiding alcohol or heavy meals, minimizing the triggers, cognitive behavioural therapy, and progressive muscle relaxation.
