Understanding Seasickness: Causes, Prevention, and Recovery
Seasickness, also known as motion sickness, is a common condition experienced by many individuals when traveling on water. Whether you're on a large cruise ship or a smaller vessel, the continuous movement can result in nausea, dizziness, and general discomfort. We will delve into why seasickness happens, preventive measures that can be taken before boarding, actions that can help alleviate symptoms while on the water, and tips for faster recovery once back on land.
Why Does Seasickness Happen?
Seasickness is a form of motion sickness caused by conflicting sensory inputs to the brain. The inner ear (vestibular system), eyes, and sensory receptors in muscles and
joints all contribute to balance and spatial orientation. When you're on a boat, these systems send conflicting messages: the inner ear senses movement as the boat rocks, but your eyes, if focused on a stationary point inside the boat, might not perceive movement. This sensory mismatch confuses the brain, triggering symptoms of seasickness, such as nausea, dizziness, cold sweats, and vomiting.
The Vestibular System and Its Role in Seasickness
The inner ear's vestibular system plays a crucial role in seasickness. It contains tiny
hair cells and fluid-filled canals that detect changes in movement and help maintain balance. When you're on a boat, these structures respond to the rolling and pitching of the water, while your eyes may tell your brain you're stationary. This discord between what your inner ear senses and what your eyes see is the primary cause of seasickness.
Risk Factors for Seasickness
Certain individuals are more prone to seasickness than others. Factors that increase your susceptibility include:
Genetics: Some individuals have a genetic predisposition to motion sickness. According to research, up to 30-50% of people are genetically predisposed .
Fatigue or Stress: Physical or mental exhaustion can exacerbate seasickness.
Hormonal Changes: Pregnant women and individuals undergoing hormonal changes may be more susceptible to motion sickness.
Previous Episodes: Those who have experienced seasickness before are more likely to suffer from it again.
Treatment Options Before Going on the Water
Prevention is key when it comes to seasickness. While it's impossible to guarantee you'll avoid it, there are various strategies and medications available to minimize the risk. As all ways, before taking any medication, including over the counter, consult with a Physician to find out what is right for you and your personal health conditions.
Medications
Scopolamine (Transderm Scop): This is one of the most commonly prescribed medications for preventing motion sickness. It comes in the form of a patch applied behind the ear. Scopolamine works by blocking signals from the vestibular system to the brain, preventing the mismatch that causes seasickness .
Effectiveness: Studies have shown that scopolamine patches can reduce seasickness symptoms by up to 80% .
How to Use: Apply the patch 4 hours before travel. It remains effective for up to 72 hours.
Side Effects: Common side effects include dry mouth, blurred vision, and drowsiness.
Antihistamines: Non-prescription antihistamines such as Dramamine (dimenhydrinate) and Bonine (meclizine) are widely used for motion sickness. These work by dulling the brain's response to the vestibular system's signals.
Effectiveness: These are less potent than scopolamine but can still be highly effective for mild to moderate seasickness .
How to Use: Take the medication at least 30 minutes before boarding. Re-dose according to the product instructions, typically every 4-6 hours.
Side Effects: Common side effects include drowsiness, dry mouth, and sometimes blurred vision.
Ginger Supplements: Ginger has been used for centuries as a natural remedy for
nausea, including motion sickness. Research suggests that ginger supplements may help reduce the intensity of seasickness symptoms. This is Ocean Therapy's primary go to along with Ginger ale for our guests.
Effectiveness: Some studies suggest ginger can be as effective as over-the-counter medications .
How to Use: Take ginger in capsule form or as a tea 30 minutes before travel.
Side Effects: Ginger is generally well-tolerated, with few side effects. However, high doses may cause heartburn or mild digestive discomfort.
Behavioral Preparations
Rest Well: Fatigue increases the likelihood of seasickness, so it's essential to be well-rested before your trip.
Light Meal: Eat a light, non-greasy meal before departure. Avoid alcohol, large meals, or rich, fatty foods, which can exacerbate nausea.
Hydration: Drink plenty of water before your trip, but avoid overhydrating, which could cause bloating or discomfort.
What to Do to Help on the Water
If you begin to experience symptoms of seasickness while on the water, there are several techniques you can use to alleviate discomfort.
Focus on the Horizon
One of the best strategies for minimizing seasickness is to step outside and focus on the horizon. By doing so, you synchronize what your eyes see with the motion your inner ear senses, reducing the sensory conflict that leads to nausea.
Find a Stable Position
Positioning yourself in the center of the boat, where there is the least amount of movement, can help minimize the effects of the boat's rocking. For those on larger vessels, going to the lower levels often provides more stability than staying at the top.
Fresh Air and Ventilation
Breathing fresh air can relieve nausea and dizziness. Avoid stuffy or enclosed spaces that can exacerbate the symptoms of seasickness. If you're inside, try to move to an area with better airflow.
Acupressure and Wristbands
Acupressure wristbands, such as Sea-Bands, apply gentle pressure to the P6 (Neiguan) point on the wrist, which has been linked to relieving nausea in both traditional Chinese medicine and Western studies .
Effectiveness: Studies on the effectiveness of acupressure wristbands are mixed. Some individuals report significant relief, while others see little difference.
How to Use: Wear the band before experiencing symptoms, and ensure the bead is positioned correctly on the wrist.
Stay Hydrated and Eat Light Snacks
If you're feeling seasick, sipping on water or nibbling on dry crackers can help settle your stomach. Avoid heavy, greasy, or acidic foods that can worsen nausea.
What to Do After to Speed Recovery
Once back on land, the symptoms of seasickness typically subside within a few hours. However, for some individuals, symptoms may linger, especially if the trip was long or particularly rough. Here are some tips to speed up recovery:
Rehydration
Dehydration exacerbates nausea and dizziness, so it's essential to rehydrate as soon as you're back on land. Water, electrolyte drinks like Pedialyte, or diluted fruit juices can help replenish lost fluids. IV Therapy is also an extremely efficient way to maintain optimal hydration by delivering fluids directly into the bloodstream. This method quickly replenishes lost electrolytes and fluids, making it ideal for recovery from dehydration caused by illness, intense physical activity, or after-effects of alcohol consumption, ensuring rapid rehydration and revitalization. Included in the IV Therapy is Ondansetron or better known as Zofran, This is a prescription medication effective in preventing and alleviating nausea and vomiting, common symptoms of a seasickness and hangover. Infused intravenously, Zofran begins to work within minutes, providing quicker relief compared to oral medication. By directly entering the bloodstream, it ensures maximum absorption and faster symptom relief without the need to pass through the digestive tract first.

Take Anti-nausea Medication
If you are still feeling unwell after the trip, consider taking an anti-nausea medication, such as Meclizine or Dimenhydrinate, which can help ease lingering symptoms.
Get Plenty of Rest
Your body needs time to recover after seasickness, particularly if you experienced vomiting or fatigue. Try to rest in a stable environment with minimal movement, and avoid activities that require concentration or balance until you feel fully recovered.
Light Physical Activity
In some cases, light exercise, such as walking, can help re-establish a sense of balance. If you're feeling up to it, a gentle stroll may aid your recovery.
Recovery in Extreme Cases: Mal de Debarquement Syndrome
For some, the sensation of movement persists long after disembarking, a condition known as Mal de Debarquement Syndrome (MdDS). This rare but prolonged disorder can last weeks or even months after the trip . While most cases resolve on their own, treatment options include physical therapy focused on balance and movement desensitization. Please contact your Health Care provider for diagnoses and treatment.
Seasickness Product Options
There are several products on the market specifically designed to help prevent and manage seasickness symptoms. These include:
Transderm Scop (Scopolamine Patch): Available by prescription, this patch is a long-lasting and effective solution for individuals prone to severe motion sickness.
Dramamine (Dimenhydrinate): A widely used over-the-counter medication that provides relief from mild to moderate seasickness symptoms.
Bonine (Meclizine): Another antihistamine option that is less sedating than Dramamine, making it a better option for individuals who want to avoid drowsiness.
Sea-Bands: These acupressure wristbands provide a drug-free alternative that can help reduce nausea for some individuals.
Ginger Chews/Capsules: For those looking for a natural option, ginger supplements or candies can offer relief from nausea.
Conclusion
Seasickness is an uncomfortable but manageable condition. Understanding why it happens and taking preventative measures can significantly reduce your chances of experiencing it. From medications like scopolamine and antihistamines to natural remedies like ginger, many options exist to help prevent and alleviate seasickness symptoms. Once on the water, strategies like focusing on the horizon, staying hydrated, and wearing acupressure wristbands can make a difference. After the trip, rest, rehydration, and gentle activity can help speed up recovery.
