Sea Sickness and Pregnancy A Guide to Snorkeling

Staring out at the gorgeous Hawaiian water, but feeling a little worried about getting nauseous? You're not the only one. If you've ever felt that tell-tale queasiness on the water, you might think of sea sickness and morning sickness as cousins—and you wouldn't be wrong. They're surprisingly similar, and thankfully, both are manageable with a few simple tricks.

Why Pregnancy Can Amplify Sea Sickness

If you feel like you're suddenly more sensitive to motion now that you're pregnant, trust your gut—you’re not imagining it. It’s an incredibly common experience, and it all comes down to the amazing physiological changes happening inside your body. When you're out on a boat, it can create the perfect storm for nausea.

Hormonal surges, especially estrogen and progesterone, are the main culprits. While they're absolutely essential for a healthy pregnancy, they come with a few interesting side effects. One of them is slowing down your digestion, which can leave your stomach feeling a bit unsettled and more prone to queasiness.

Pregnancy brings a wave of changes that can make you more susceptible to that rocky feeling on a boat. Here’s a quick look at the main factors at play.

Pregnancy Factors That Increase Sea Sickness Risk

Factor	Effect on the Body	Impact on Sea Sickness
Hormonal Changes	Surges in estrogen and progesterone slow digestion.	A slower-emptying stomach is more easily upset by motion.
Increased Blood Volume	Your body is working harder to circulate more blood.	This can sometimes affect blood pressure and make you feel dizzy.
Heightened Senses	Many women experience a stronger sense of smell and taste.	Strong smells, like boat fuel, can become powerful nausea triggers.
Sensory Sensitivity	The brain's motion-processing center becomes more sensitive.	Minor conflicts between what you see and what you feel can trigger nausea.

These factors work together, creating a lower threshold for motion sickness than you might have had before pregnancy.

The Brain and Body Mismatch

Another big piece of the puzzle is how your brain processes movement. Your inner ear, eyes, and body are constantly sending signals to your brain to keep you balanced. On a boat, those signals get jumbled—your eyes might see the steady horizon, but your inner ear feels the roll of the waves.

During pregnancy, your brain's motion-sensing center gets a little over-protective. This means even a slight mismatch in sensory signals—something you might not have noticed before—is now enough to set off the nausea alarm.

This explains why some women who've never been seasick in their life suddenly struggle with it while pregnant. And if you were already prone to motion sickness, pregnancy can definitely turn up the volume.

Did you know that what we call "morning sickness," or NVP (nausea and vomiting of pregnancy), affects a huge 70-80% of all pregnant women? Interestingly, this common symptom is often linked to positive outcomes. The same hormones causing NVP are what make you more sensitive to the sway of a boat. You can read more about the science behind it if you're curious.

Ultimately, dealing with sea sickness while pregnant doesn't mean you have to stay on shore. Just understanding why it's happening is the first step toward managing it and getting back to enjoying your time on the water.

Safe and Natural Remedies for Expectant Mothers

Dealing with sea sickness while you’re pregnant doesn’t have to ruin your day on the water. Thankfully, you don’t need to reach for medication right away. A handful of simple, drug-free strategies can make a world of difference and keep you feeling your best.

It all starts with your stomach. Boarding a boat after a big, heavy meal is a recipe for trouble. Instead, the trick is to eat small, bland snacks frequently to keep your stomach settled.

Here’s what you should have in your bag:

• Crackers and Pretzels: These simple carbs are perfect for absorbing stomach acid and warding off that empty-stomach queasiness.

• Dry Toast or Cereal: A light, simple breakfast before you head out is a brilliant move.

• Stay Hydrated: Sip water steadily throughout the day. Getting dehydrated can make dizziness and nausea feel so much worse.

Tried-and-True Natural Fixes

Beyond what you eat, a few natural remedies are famously effective at calming that queasy feeling. Best of all, they are completely safe to use during pregnancy.

Ginger is one of the most trusted natural nausea-fighters out there. For centuries, people have used this amazing root to settle an upset stomach. You can easily find delicious and convenient ginger chews to keep in your pocket for quick relief when you need it most.

Another fantastic option is acupressure. This ancient technique works by applying steady pressure to a spot on your inner wrist called the P6 (Nei Guan) point. The pressure helps block the nausea signals your stomach tries to send to your brain.

The easiest way to get that consistent pressure on a moving boat is with a specialized wristband. Sea Band wristbands are an inexpensive, popular choice that applies gentle, continuous pressure to this spot. They work to prevent nausea before it even starts. To see exactly how they work, check out our deep dive on how a sea sickness bracelet works.

Simple Tricks to Settle Your Senses

Sometimes, it’s the smallest adjustments that have the biggest payoff. The way you position yourself and what you focus on can make or break your experience on the boat.

First, find some fresh air. If you start to feel a bit off, head out onto the open deck. Being in a stuffy, enclosed cabin will only make you feel worse. The ocean breeze is your friend!

Next, give your brain something stable to look at. Find a fixed spot on the distant horizon and lock your eyes on it. This helps your brain make sense of the boat's motion, cutting down on that confusing sensory input that triggers motion sickness.

Finally, stay away from strong smells. Pregnancy can crank your sense of smell up to eleven, making odors like boat fuel or strong perfumes instant nausea triggers. Try to position yourself upwind from any powerful scents to keep your stomach happy and calm.

Exploring Medication Options with Your Doctor

While natural remedies are often the perfect first line of defense against both sea sickness and that all-too-familiar pregnancy nausea, it never hurts to have a backup plan. Having a "just in case" option can bring a lot of peace of mind. Think of this section as a way to help you get ready for a productive chat with your healthcare provider—it’s purely educational, not medical advice.

When you sit down with your doctor, you’ll probably talk about both over-the-counter (OTC) and prescription medications. Each one has its own profile, and that’s especially true when you’re pregnant.

Common Over-the-Counter Choices

You’ve likely seen Dramamine and Bonine on pharmacy shelves; they're the go-to remedies for motion sickness for a reason. Knowing a little about them can help you ask your doctor the right questions.

• Dramamine (Dimenhydrinate): This is an antihistamine that’s very effective for motion sickness, but it can make you drowsy. You can find Dramamine pills almost everywhere.

• Bonine (Meclizine): Also an antihistamine, Bonine pills are another popular pick, often chosen because they tend to cause less drowsiness than Dramamine.

When you bring these up with your doctor, you can ask about their safety records during pregnancy and if one might be a better choice for you. Every pregnancy is different, so your doctor’s advice is what really counts.

Prescription and Other Remedies

If over-the-counter options don't seem like the right fit, or if your doctor thinks you need something stronger, they might bring up prescriptions. A common one is the Ship-EEZ Seasickness Patch, which uses a medication called scopolamine. You just stick it behind your ear for long-lasting relief.

The core of your conversation with your doctor will be about weighing the benefits against any potential risks. They'll look at your health history, how far along you are, and just how severe your nausea is before suggesting a path forward.

Working together like this ensures you land on a plan that feels safe and effective. Your doctor can help you feel totally confident and ready for your adventure on the water. For a bit more background on the different types available, our guide on sea sick tablets can give you extra info to bring to your appointment.
