Disembarking a cruise ship can sometimes be accompanied by a range of symptoms such as dizziness, nausea, and vomiting, commonly known as "disembarkation syndrome" or "mal de debarquement." These symptoms can mimic those of seasickness, even though the ship is no longer moving. In most cases, these symptoms are mild and resolve within a few hours or days, but they can be more severe and long-lasting in some individuals.
The exact cause of disembarkation syndrome is not fully understood, but it is thought to be related to the brain's adjustment to being on stable ground after a period of time spent on a moving ship. The symptoms can be exacerbated by factors such as the length of the cruise, the size of the ship, and the individual's susceptibility to motion sickness.
