The most effective seasickness tip doesn't start when you're already throwing up. It starts the night before. The CDC explains that motion sickness occurs when information from your eyes, inner ears, and motion sensors 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 trip more uncomfortable. If you have to catch a boat at Ao Tien in the morning, don't stay up until 2 AM just because you're traveling.
Tip 2: Don't leave your stomach completely empty
The CDC recommends eating small amounts, drinking plenty of water, and limiting alcohol/caffeine if you're prone to motion sickness. Breakfast should be light:
-
Bread.
-
Porridge.
-
Easily digestible foods.
There is no need for a massive buffet right before boarding a speedboat.
Tip 3: Look into the distance
On board: Looking at the horizon > looking at your phone. Constantly reading messages while your body senses movement but your eyes are fixed on a stationary screen can easily worsen symptoms.
Tip 4: Choose a suitable spot
If you have a choice, ask staff for a spot that is:
-
Low in motion.
-
Well-ventilated.
-
Has an outside view.
On larger boats, the area near midship tends to experience less motion than the ends.
Tip 5: Keep your head relatively still
Resting your head, resting, or closing your eyes can help some people. The CDC also lists lying down, sleeping, or closing your eyes as behavioral measures that can help relieve symptoms.
Tip 6: If you need medication, use it properly
The CDC notes that motion sickness medications are more effective when taken before exposure to motion, but many cause drowsiness and have their own contraindications. Therefore, a handbook should not recommend a one-size-fits-all medication for all guests. If you are prone to severe motion sickness:
-
Consult a doctor/pharmacist.
-
Read the instructions.
-
Do not increase the dose on your own.
-
Do not combine multiple medications.
-
Be especially cautious with young children.
Tip 7: Choose a trip that suits you
If you have never taken a boat trip and get carsick easily:
-
Try a Ha Long day tour first.
-
Don't immediately book a non-refundable 2–3 night cruise.
-
If traveling to an island, choose a schedule with rest time after the boat trip.
“Tips” you shouldn't rely on too much
Motion sickness wristbands, medicated oil, and ginger candies may help some people feel better, but they should not be considered guaranteed solutions. Ginger can be used as a supportive option, but if you have a history of severe motion sickness, you need a more realistic plan.
