The Importance of Hydration for Seasickness Prevention

Seasickness is a common ailment that affects many sailors and their families, especially those who are new to the sailing lifestyle. It can be a significant obstacle to enjoying your time at sea and can even discourage some from pursuing their sailing dreams. In this article, we will explore the importance of hydration in preventing and managing seasickness, as well as other practical tips and remedies to help you and your family stay healthy and comfortable while sailing.

What is Seasickness?

Seasickness, also known as motion sickness, is a condition that occurs when the body’s sense of balance and equilibrium is disrupted by the constant motion of a boat on the water. This can lead to a range of symptoms, including:

  • Nausea
  • Vomiting
  • Dizziness
  • Headaches
  • Fatigue
  • Cold sweats

These symptoms can be mild or severe, and they can vary from person to person. Some people may be more prone to seasickness than others, but almost anyone can experience it under the right conditions.

The Role of Hydration in Seasickness Prevention

One of the key factors in preventing and managing seasickness is staying properly hydrated. Dehydration can exacerbate the symptoms of seasickness and make it more difficult for your body to recover. Here’s why hydration is so important:

1. Maintaining Balance and Equilibrium

Your body’s sense of balance relies on a complex system of sensory input from your eyes, inner ears, and proprioceptors (sensors in your muscles and joints that detect movement and position). When you’re dehydrated, your body’s ability to process this sensory information can be impaired, making it more difficult to maintain your balance and increasing your susceptibility to seasickness.

2. Regulating Body Temperature

Staying cool and comfortable is essential for preventing seasickness, as overheating can make you feel even more nauseous and dizzy. Proper hydration helps your body regulate its temperature, allowing you to stay cool and comfortable even in warm, humid conditions.

3. Preventing Fatigue

Fatigue is a common symptom of seasickness, and it can make it more difficult for your body to recover from the effects of motion. Staying hydrated helps to prevent fatigue by ensuring that your muscles and organs have the water they need to function properly.

4. Reducing Nausea and Vomiting

Nausea and vomiting are the most well-known symptoms of seasickness, and they can be extremely uncomfortable and debilitating. Staying hydrated can help to reduce these symptoms by ensuring that your stomach has enough fluids to dilute stomach acids and prevent irritation.

Tips for Staying Hydrated at Sea

Now that we understand the importance of hydration for seasickness prevention, let’s explore some practical tips for staying hydrated while sailing:

1. Drink Water Regularly

The most obvious way to stay hydrated is to drink water regularly throughout the day. Aim for at least 8-10 glasses of water per day, and try to drink small amounts frequently rather than large amounts all at once. This will help to keep your body’s fluid levels stable and prevent dehydration.

2. Monitor Your Urine Color

A simple way to gauge your hydration levels is to monitor the color of your urine. If your urine is pale yellow, you’re likely well-hydrated. If it’s darker in color, you may need to drink more water.

3. Avoid Alcohol and Caffeine

Alcohol and caffeine can both act as diuretics, causing your body to lose more water than it takes in. This can lead to dehydration and make seasickness symptoms worse. Try to limit your consumption of these beverages while sailing, and opt for water or other hydrating drinks instead.

4. Eat Hydrating Foods

In addition to drinking water, you can also stay hydrated by eating foods with high water content. Fruits and vegetables like watermelon, cucumber, and oranges are great options for snacking on while sailing.

5. Replenish Electrolytes

When you sweat or lose fluids through vomiting, you also lose essential electrolytes like sodium, potassium, and magnesium. These electrolytes play a crucial role in maintaining your body’s fluid balance and preventing dehydration. To replenish your electrolytes, consider drinking sports drinks or coconut water, or eating foods rich in electrolytes like bananas and avocados.

Other Seasickness Prevention Tips and Remedies

In addition to staying hydrated, there are several other strategies you can use to prevent and manage seasickness:

1. Acclimate to the Motion

One of the best ways to prevent seasickness is to gradually acclimate your body to the motion of the boat. Spend time on the boat while it’s docked or anchored, and gradually increase the amount of time you spend sailing in calm conditions before tackling rougher seas.

2. Choose Your Location Wisely

Where you choose to spend your time on the boat can have a significant impact on your susceptibility to seasickness. Opt for a location near the center of the boat, where the motion is less pronounced, and try to stay on deck as much as possible to maintain a visual connection with the horizon.

3. Use Medications and Natural Remedies

There are several over-the-counter medications and natural remedies that can help to prevent and manage seasickness. These include:

  • Antihistamines like Dramamine and Bonine
  • Scopolamine patches, which are applied behind the ear
  • Ginger, which can be consumed as a tea, capsule, or candy
  • Acupressure wristbands, which apply pressure to a specific point on the wrist to help alleviate nausea

Always consult with a healthcare professional before using any medications or remedies, especially if you are pregnant, nursing, or have any pre-existing medical conditions.

4. Focus on Your Breathing

Deep, slow breathing can help to alleviate the symptoms of seasickness by calming your nervous system and reducing feelings of nausea and dizziness. Practice taking slow, deep breaths in through your nose and out through your mouth, and try to maintain a steady rhythm.

5. Distract Yourself

Sometimes, simply taking your mind off of your seasickness symptoms can help to alleviate them. Engage in conversation with your fellow sailors, listen to music, or focus on a task like navigating or adjusting the sails.


Seasickness can be a challenging aspect of the sailing lifestyle, but with proper hydration and the right prevention strategies, you can minimize its impact on your adventures at sea. By staying hydrated, acclimating to the motion of the boat, and using medications and natural remedies as needed, you can ensure that you and your family stay healthy and comfortable while exploring the open waters.
