Sea Sickness: How to Prevent It and What to Do If It Happens

Spending time on the water is one of the best parts of visiting places like Key West — whether it’s a boat tour, fishing trip, snorkeling excursion, or sunset cruise. But for some people, sea sickness can quickly take the fun out of the experience.

The good news? Sea sickness is common, manageable, and often preventable. This guide covers practical, non‑medical tips to help reduce the chances of sea sickness — and what to do if it does happen.

This article is for general information only and is not medical advice.

What Is Sea Sickness?

Sea sickness is a type of motion sickness that happens when your inner ear senses movement that your eyes don’t match — or vice versa. This sensory mismatch can lead to symptoms like:

  • Nausea

  • Dizziness or lightheadedness

  • Sweating

  • Headache

  • Fatigue

It can affect first‑time boaters and seasoned travelers alike, especially in rough or choppy conditions.

How to Prevent Sea Sickness Before You Get on the Boat

Preparation can make a huge difference.

Choose the Right Spot on the Boat

  • Stay near the center of the boat, where movement is usually less noticeable.

  • Lower decks often feel more stable than higher ones.

  • If possible, face forward and look toward the horizon.

Eat Smart Before Boarding

  • Avoid heavy, greasy, or spicy foods.

  • A light meal or snack is usually best.

  • Don’t board on an empty stomach — hunger can make symptoms worse.

Stay Hydrated

  • Drink water before and during your trip.

  • Avoid excessive alcohol before heading out on the water.

Get Fresh Air & Sunshine

  • Fresh air can help your body adjust to movement.

  • Avoid enclosed spaces if possible.

Rest Well

  • Being tired can increase your chances of motion sickness.

  • Try to get a good night’s sleep before your trip.

Helpful Non‑Medical Remedies People Commonly Use

While everyone is different, many travelers find these methods helpful:

  • Ginger (candies, chews, tea, or cookies)

  • Acupressure wrist bands

  • Peppermint (tea or lozenges)

  • Controlled breathing and relaxation techniques

These are commonly used comfort strategies and don’t require medication.

What to Do During the Boat Ride

If you start to feel uneasy:

  • Keep your eyes on the horizon or a fixed point.

  • Sit or stand where movement feels minimal.

  • Avoid reading, scrolling on your phone, or focusing on screens.

  • Take slow, deep breaths.

  • Sip water or ginger tea if available.

Staying calm and relaxed often helps prevent symptoms from escalating.

What to Do If Sea Sickness Happens

Even with preparation, sea sickness can still occur. If it does:

  • Let the crew know — they’re experienced and can help you relocate to a better spot.

  • Stay upright and avoid lying flat unless advised by crew.

  • Continue looking at the horizon.

  • Take small sips of water.

  • Step into fresh air if you’re inside.

Most cases ease once the boat returns to calmer waters or docks.

After the Boat Ride

Once back on land:

  • Sit down and rest for a few minutes.

  • Drink water and eat something light.

  • Give your body time to fully re‑adjust.

Lingering sensations usually fade fairly quickly after leaving the boat.

Final Tips for a Better Experience on the Water

  • Choose calm‑weather days when possible.

  • Shorter trips are often easier than long excursions.

  • Catamarans and larger boats tend to be more stable than smaller vessels.

  • Don’t be embarrassed — sea sickness is extremely common.

With a little preparation and awareness, most people can still enjoy their time on the water without letting sea sickness take over the experience.
