Some toxins that they consumed in the past attacked the inner ear. But why should that conflict cause us to feel nauseated and puke? One theory is that upchucking is tied into an evolutionary means humans developed to protect themselves from being poisoned. It appears reasonable that conflicting motion sensors can cause us to become dizzy. Īnother issue of study in the field of motion sickness is our stomachs. And while vision is often a major component in whether or not someone suffers from motion sickness, blind people can become motion-sick, so sight is not a critical factor. Scientists also know motion sickness can only occur if we have our inner ear, the organ that senses motion. Studies indicate your heightened sensitivity could be genetic. Some people are definitely more sensitive to motion than others. The theory that our senses being at odds with one another is what causes these physical symptoms is mainly conjecture. While scientists are pretty confident these sensory discrepancies cause motion sickness, they don't know why. Typical motion sickness symptoms include nausea, headache, dizziness, pale skin, cold sweats, increased salivation, fatigue and vomiting. ![]() This causes confusion and can upset your body. But your inner ear and sensory receptors are telling your brain you're sitting still. Or perhaps you're watching the IMAX movie "Avatar." Your eyes are seeing motion as the movie makes it appear you're flying over the great land of Pandora. Your inner ear senses the way the waves are gently rocking it, but your eyes aren't detecting any movement. So how can these sensors get scrambled? Let's say you're on a boat. Studies show that migraine-sufferers often develop it, as do those who sleep poorly.įinally, research has also shown that experiencing this ailment could be genetic. Location: Sitting in the back of a car makes it worse than in the front (which is one reason some say children suffer more from motion sickness than adults.) Also, if the vehicle is not well-ventilated, that can also bring it on.Ĭertain illnesses and conditions: If you're pregnant, prone to nausea or vomiting, or are a nervous or anxious person, you're more likely to get motion sickness. Gender and Race: Studies show women are more susceptible than men, and Asians more than whites or blacks. (We'll explain that connection on the next page.) But if you suffer from motion sickness and make it to your 50s, you may finally get a reprieve, as this is when inner-ear function starts to decline. Once in their teens, many people outgrow motion sickness, but certainly not all. Here are some other risk factors for motion sickness :Īge: Motion sickness tends to strike kids the most, specifically those between the ages of 2 and 12. Half of us who suffer from motion sickness will only succumb to an attack if the movement is quite noticeable - for example, riding in a boat when the water is rough as opposed to when it's calm. You can also develop motion sickness by watching a 3-D or IMAX movie, playing video games or looking through a microscope. And if you're very unfortunate, your stomach might remain queasy for the rest of the day.Ībout 25 to 40 percent of people are susceptible to motion sickness, the term used to cover any kind of ill feeling resulting from movement, whether in a car, boat, airplane or amusement park ride. You might end up puking no matter what you do. Maybe unroll the window, too, or have the driver pull over so you can get out and gulp some fresh air. If not, you'll have to put it away for the rest of the trip. ![]() If you're lucky, you can simply look up from your laptop for a few minutes and you'll be fine. You're riding in the car, trying to get a little work done on your laptop, when you're hit by a sudden wave of nausea.
