Everything You Need to Know About Seasickness on a Cruise — And How to Avoid It

For many first-time cruisers, seasickness is a very real concern. But with today’s massive ships and high-tech stabilizers that keep things steady even in choppy waters, there's really not all that much to worry about, especially if you take a few simple precautions. Here, we break down everything you need to know about seasickness on cruise ships, along with expert tips and insights to ensure, well, smooth sailing. 

What is Seasickness? 

According to Bahar Adeli, MD, a spokesperson for the American Gastroenterological Association (AGA), seasickness is a form of motion sickness that's "characterized by symptoms like nausea, dizziness, and discomfort." Per the pro, it stems from "conflicting signals your senses send to your brain when you're at sea." For example, your inner ear can tell you’re moving, but your eyes insist you’re not — a disconnect that leaves your brain confused and your stomach queasy.

What You Need to Know About Seasickness on a Cruise

It varies from person to person 

"Seasickness is a concern for many first-time cruisers, and it's vital to evaluate your susceptibility before setting sail," says Dr. Adeli. She continues, telling ShermansTravel, "Keep in mind that susceptibility varies from person to person, with those who experience motion sickness on land, such as in cars, buses, trains, or planes, being more prone to seasickness." Additionally, certain folks — like children under the age of two, migraine sufferers, and pregnant people — are more susceptible to seasickness, as well.  

It's preventable 

Dr. Adeli explains that "planning ahead and taking necessary precautions can help ensure a smoother cruise experience." While there are over-the-counter medications that can help — including dimenhydrinate (e.g., Dramamine), meclizine (e.g., Antivert), and diphenhydramine (e.g., Benadryl) — the doctor recommends consulting with your primary care physician, as these drugs can be sedating and may interact with other medications or have side effects. However, if your doctor is on board (pun intended, of course), she says that taking a first dose of an anti-nausea medication before boarding the ship can "significantly reduce the risk of seasickness."

It's less common on larger ships 

"Seasickness can be mitigated by choosing larger ships equipped with advanced stabilizers, especially for longer voyages," says Dr. Adeli. For example, according to its website, megaships all "use stabilizers — fins built off a ship's port and starboard sides along the water line — to reduce side-to-side motion so most guests never experience any motion sickness."
