Motion sickness (Seasickness) occurs when there is a conflict between what your eyes see and what your inner ear (vestibular system) senses regarding motion. In rough sea conditions, this sensory mismatch is heightened, leading to nausea, vomiting, and secondary gastric distress like bloating or gas. Since you spend a significant part of the year at sea, managing this involves both pharmacological and behavioral interventions to help your brain 'habituate' to the ship's motion."
Next Steps
To reduce symptoms, try staying in the mid-ship area (where motion is minimal) and keep your eyes fixed on the stable horizon rather than looking down at a screen or book. Pharmacologically, medications like Cinnarizine or Promethazine can be very effective if taken 30-60 minutes before the sea gets rough. For the gas issues, avoid large, fatty meals and carbonated drinks, as they slow down gastric emptying and worsen nausea."
Health Tips
Many anti-motion sickness medications can cause significant drowsiness, which might interfere with your duties on board. It is essential to test how you react to these medications during a calm period or consult a doctor to find a non-drowsy alternative. If vomiting becomes severe and you cannot retain fluids, seek immediate medical attention from the ship’s medical officer to prevent dehydration."
