Seasick caused by the rocking motion of the ship. Some people are vulnerable to the condition with minor stimulus and will feel seasick simply by setting foot on a boat, while others are relatively immune. In some conditions, seasickness can be dangerous, such as if you're steering a boat or want to do a scuba diving.
These are some tips on how to avoid seasick:
- Never go with empty stomach. In the other hand, don't eat too much either before departed.
- Take anti-seasickness/nausea capsule 15 minutes before leaving.
- If possible, choose a bigger ship. Usually bigger ship have the ability to reduce the effect of sea waves.
- Take a sit or choose a cabin in the back. The back side have less movement than the front.
- Keep eyes directed to the fixed shore or horizon, where possible.
- Move into a position where fresh air is blowing on their face.
- Lying down on your backs and closing eyes.
- Chew something spicy also helps, like mint gum, or a ginger candy.
