The most effective tips for preventing seasickness don't begin when you're already throwing up. They start the night before. The CDC explains that motion sickness occurs when information from your eyes, inner ear, and sensory nerves doesn't match; looking at the horizon and limiting visual tasks like reading screens can help reduce this conflict.
Tip 1: Get enough sleep
Lack of sleep makes the boat ride much more uncomfortable. If you have to catch a boat at Ao Tien in the morning, don't stay up until 2:00 AM just because you're traveling.
Tip 2: Don't leave your stomach completely empty
The CDC recommends eating small amounts, staying well-hydrated, and limiting alcohol and caffeine if you are prone to motion sickness. Breakfast should be light:
-
Bread.
-
Porridge.
-
Easily digestible food.
There is no need for a massive buffet right before boarding a speedboat.
Tip 3: Look into the distance
Onboard: Looking at the horizon > looking at your phone. Continuously reading messages while your body feels the motion but your eyes focus on a stationary screen can easily exacerbate symptoms.
Tip 4: Choose the right seat
If you have a choice, ask the crew for seats that:
-
Experience less motion.
-
Are well-ventilated.
-
Offer an outside view.
On larger vessels, the midship area typically experiences less motion than either end.
Tip 5: Keep your head relatively still
Resting your head, relaxing, or closing your eyes can help some people. The CDC also lists lying down, sleeping, or keeping your eyes closed as behavioral measures that can help relieve symptoms.
Tip 6: If medication is needed, use it properly
The CDC notes that motion sickness medications are more effective when taken prior to motion exposure, but many cause drowsiness and carry specific contraindications. Therefore, this handbook does not recommend a one-size-fits-all medication for every traveler. If you are prone to severe motion sickness:
-
Consult a doctor or pharmacist.
-
Read the instructions carefully.
-
Do not increase the dosage on your own.
-
Do not combine multiple medications.
-
Exercise particular caution with young children.
Tip 7: Choose an itinerary that suits you
If you have never taken a boat and easily get motion sickness:
-
Try a Ha Long day tour first.
-
Don't immediately book a non-refundable 2–3 night cruise.
-
If traveling to an island, pick a schedule with time to rest after the crossing.
“Tips” you shouldn't rely on too heavily
Acupressure wristbands, medicated oils, and ginger candies may make some people feel better, but they shouldn't be considered guaranteed solutions. Ginger can serve as a supportive remedy, but if you have a history of severe motion sickness, you need a more practical plan.
