Some people also experience additional symptoms, including:

Mal de debarquement syndrome
Mal de debarquement syndrome means "illness of disembarkation". It is a very rare condition that is triggered by travel, such as on a boat or plane. The symptoms last long after the journey has finished.
Instead of the usual symptoms of motion sickness, such as nausea, people with mal de debarquement syndrome feel as though they are rocking or bobbing, and may describe it as feeling as if they are still on the boat. Many people feel like this for a few hours after a journey, but for people with mal de debarquement syndrome, the symptoms can last for months or even years.
