Disembarkation sickness, medically known as Mal de Debarquement Syndrome (MdDS), is a neurological condition where a person continues to feel a sensation of rocking, bobbing, or swaying long after they have returned to stable land. While most people feel "wobbly" for a few hours after a cruise (often called "land sickness"), true MdDS in 2026 is recognized as a disorder of neuroplasticity where the brain has successfully adapted to the ship's motion but fails to readapt to the stillness of land. Interestingly, many sufferers report that their symptoms actually disappear when they are back in a moving vehicle, such as a car or another ship. In 2026, treatments include specialized vestibular rehabilitation and "brain retraining" exercises using virtual reality. While most cases resolve within days, some individuals can experience these "phantom waves" for months or even years. It is more common in women aged 30–60 and is distinct from standard seasickness, as it occurs only after the motion has stopped.
