The most effective seasickness tips do not begin once you have already vomited. They begin the night before. The CDC explains that motion sickness occurs when information from the eyes, inner ear, and sense of movement do not match; looking at the horizon and limiting visual tasks such as reading a screen 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 from Ao Tien in the morning, do not stay up until 2 a.m. just because you are traveling.
Tip 2: do not leave your stomach completely empty
The CDC recommends eating small amounts, drinking enough water, and limiting alcohol/caffeine if you are prone to motion sickness. Breakfast should be light:
-
Bread.
-
Porridge.
-
Easy-to-digest foods.
There is no need for a huge buffet meal right before boarding a high-speed boat.
Tip 3: look into the distance
On the boat: Look at the horizon > look at your phone. Reading messages continuously while your body senses movement but your eyes are focused on a stationary screen can easily make the symptoms worse.
Tip 4: choose a suitable position
If you have a choice, ask the staff about a spot that is:
-
Less subject to rocking.
-
Well ventilated.
-
With an outside view.
On a large boat, areas near the middle of the vessel tend to move less than the two ends.
Tip 5: keep your head relatively still
Resting your head, taking a break, or closing your eyes may help some people. The CDC also lists lying down, sleeping, or closing your eyes as behavioral measures that may help reduce symptoms.
Tip 6: if you need medication, use it correctly
The CDC notes that motion-sickness medication is more effective when taken before exposure to movement, but many medications cause drowsiness and have their own contraindications. Therefore, the handbook should not prescribe one medication for every guest. If you are prone to severe motion sickness:
-
Ask a doctor/pharmacist.
-
Read the instructions.
-
Do not increase the dosage yourself.
-
Do not combine multiple types.
-
Be especially cautious with young children.
Tip 7: choose a trip that suits you
If you have never traveled by sea and get motion sickness very easily:
-
Try a one-day Ha Long tour first.
-
Do not immediately book a non-refundable 2–3-night cruise.
-
If you are traveling to an island, choose a schedule that allows time to rest after the boat trip.
“Tips” that should not be trusted too much
Motion-sickness wristbands, medicated oil, and ginger candy may make some people feel more comfortable, 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 practical plan.
