Preventing seasickness (motion sickness) is best achieved through a combination of location, medication, and behavior. When on a ship, you should try to stay in the middle of the vessel and on a lower deck, as this is the "pivot point" where the motion of the ocean is least felt. Behavioral strategies include keeping your eyes on the horizon, which provides a stable visual reference point for your brain, and avoiding reading or staring at screens. Dietary choices also matter; stick to bland foods like crackers and ginger (ginger ale or ginger chews are proven natural remedies) and avoid heavy, greasy meals or excessive alcohol. For medical prevention, many travelers use over-the-counter antihistamines like Meclizine (Dramamine Less Drowsy) or the Scopolamine patch (a prescription "behind-the-ear" patch). These should be taken/applied at least 1 to 4 hours before you board, as they are far more effective at preventing the onset of sickness than treating it once you are already nauseous. In 2026, "Sea-Bands" (acupressure wristbands) also remain a popular non-drug alternative.
