That's a Thing?

I felt lucky not to experience any sea sicknesses whatsoever aboard the cruise ship we spent 7 nights on last week. Sure, I felt the motion of the ship, but it seemed like a relatively calm passage. A day and a half into our journey, we disembarked at the first port of call, Icy Strait Point. It would be the worst weather of the trip, rainy and in the low 50s. We were only there for a few hours, and most of what there was to see was built on the pier where the tenders dropped us. As we made our way through the cannery-turned-museum-and-gift shops, I felt the floor swaying. This place must be a floating pier, I assumed, although it didn't really look like it.

In Juneau, Skagway, and Ketchikan, I felt a bit of dizziness, but soon I was on a cable car, train, and tour bus, respectively. I mentioned the feeling of vertigo in passing to my traveling companions, but it was mild and we let it drop. Last night? Heidi was complaining of bed spins, and I was still reeling. Google to the rescue: we seem to have mal de debarquement, also known as "land sickness," although thankfully ours seem to be mild cases.

According to Web MD:

Mal de debarquement syndrome (MdDS) is a rare and little understood disorder of the body's balance system (vestibular system) and refers to the rocking sensation and/or sense of imbalance that persists for an excessive length of time after an ocean cruise, plane flight or other motion experience. Most people after exposure to an ocean trip or long airplane ride will experience "motion" after the event is over and for a short period of time, with two days being the upper limit of normal. But for persons with MdDS, these sensations may last for 1 month or a year or even many years. Symptoms may diminish in time or periodically disappear and reappear after days, months, or years, sometimes after another motion experience or sometimes spontaneously. This syndrome is probably more common than the literature might lead us to believe, as the level of awareness in the general population as well as among health personnel is very low.

The disproportionate length of time over which the discomfort persists is normally unaccompanied by nausea, nor is it responsive to motion-sickness drugs.

For reasons that are not understood, middle aged women are overwhelmingly more likely to come down with MdDS than are men. However, most studies so far have disavowed hormones as a cause.

Coincidentally, Heidi ran into one of our neighbors this afternoon and as they discussed our trip the topic of this pesky rocking sensation came up, too. "Oh, you have mal de debarquement!" our neighbor, who is also a middle-aged woman, exclaimed. "Mine lasted 12 days-- I staggered around work for two whole weeks!"

Ours seem to be a mild cases and I have confidence they will be gone soon. If not? I guess it's just kind of a neurological souvenir of our great vacation.
