It may feel counter-intuitive, but traveling on an empty stomach is more likely to make you feel ill than traveling after a light meal. To help settle your stomach, have a simple snack about one hour before you depart, and remember to continue snacking every few hours throughout the cruise.

Yes, clinical studies and medical experts generally agree that you are more likely to experience seasickness on an empty stomach. When the stomach is completely empty, gastric acid can slosh around more freely, which often intensifies the sensation of nausea and dizziness caused by motion. Doctors recommend eating a light, healthy meal before traveling by sea—focusing on bland carbohydrates like crackers, bread, or oatmeal—while avoiding heavy, greasy, or acidic foods that can be harder to digest. However, overeating is equally detrimental; the goal is to have a "settled" stomach. Staying hydrated with water or ginger tea is also essential. If you begin to feel unwell while on board, nibbling on dry crackers or ginger biscuits can help absorb stomach acid and provide a mild distraction for the digestive system, helping to mitigate the onset of more severe motion sickness symptoms during your journey.
