Take motion sickness medicine one to two hours before traveling.

Choose the right seat. The front passenger seat is best in the car. Choose the midpoint on a boat. Sit over the wing on a plane. Face forward on a train. Sit near a window on a train. These seats have fewer bumps. They allow you to see the horizon. If you are on a cruise, book a cabin in the front or middle of the ship. Request a room that is closest to the water level.

Get plenty of air. Use the air conditioner or roll down the window in a car. Direct the vent toward you on a plane. Sit near a window when you’re on a covered boat.

Avoid things you can’t change. For example, don’t ride on a speed boat. Waves and bumps can make you sick. If you can’t avoid it, take medicine in advance.

Don’t read while riding in a car, plane, or boat. Look out the window at the horizon. Look at a distant object.

Lie down when you feel sick.

Avoid a heavy meal before or during travel. Eat small portions of plain food instead. Don’t eat greasy, spicy, or acidic foods before or during travel.

Drink lots of water. Avoid alcohol.

Talk to your doctor about different therapies. This might include pressure bands (worn on your wrist).
