Stand with legs bent, and anticipate the motion by moving entire body Pilot the vehicle or connect with steering device 7 If unable to view the true visual horizonĪctively synchronize the body with the motion Look toward the motion or direction of travel Synchronize the visual system with the motionĪvoid close work (e.g., reading, looking at computer screens, photography)Īvoid spaces where the horizon cannot be seen If symptomatic, attempt to reduce, but not eliminate, motion stimuli Start travel in calm conditions and slowly increase the amount of motion exposure Gradually increase amount of motion stimuli Trains: at the lowest level, facing forward Vertical motions are worse than horizontal motionsĪvoid travel in difficult conditions and locationsĪvoid air travel in storms and turbulent conditionsĪvoid terrain with many turns, accelerations, and ups and downsĪvoid travel on water in storms and large wavesĪvoid travel through fog, clouds, and other conditions with poor visibilityĬhoose location within the vehicle that minimizes motionĪutomobiles: driver's or front passenger seat, facing forward 3, 4īoats: facing toward the waves, away from the rocking bow, near the surface of the water 2īuses: near the front, at the lowest level, facing forward 3 Rotary motion is worse than linear motion Low-frequency motions are worse than high-frequency motions Nonsedating antihistamines, ondansetron, and ginger root are not effective in the prevention and treatment of motion sickness.Īvoid particularly noxious types of motionsĬomplex (multiple and off-axis) motions are worse than simple (one-axis) motions First-generation antihistamines, although sedating, are also effective. Scopolamine is a first-line medication for prevention of motion sickness and should be administered transdermally several hours before the anticipated motion exposure. Patients should also attempt to reduce other sources of physical, mental, and emotional discomfort. Other behavioral strategies include watching the true visual horizon, steering the vehicle, tilting their head into turns, or lying down with their eyes closed. Slow, intermittent exposure to the motion can reduce symptoms. Patients should learn to identify situations that will lead to motion sickness and minimize the amount of unpleasant motion they are exposed to by avoiding difficult conditions while traveling or by positioning themselves in the most stable part of the vehicle. Early self-diagnosis should be emphasized, and patients should be counseled about behavioral and pharmacologic strategies to prevent motion sickness before traveling. Although nausea is the hallmark symptom, it is often preceded by stomach awareness, malaise, drowsiness, and irritability.
It is thought to be caused by conflict between the vestibular, visual, and other proprioceptive systems. Motion sickness is a common syndrome that occurs upon exposure to certain types of motion.
