ANSWER: A “greyout” is when the vision dims in light and color. This is due to temporary loss of blood to the brain and is a common finding in people who are on roller coasters with vertical loops and corkscrews.
Other health conditions can make going on high-speed rides unsafe, including pregnancy, recent surgery, heart problems, high blood pressure and aneurysms, as well as the influence of drugs or alcohol.
While there's no way to know exactly how often such experiences occur on roller coasters, blacking out or graying out during rides is medically understandable, experts say.
Balance is determined by your inner ear struggling to keep you aligned with a level plane so, no, closing your eyes will not assist whenever you're struggling with balance concerns on a roller coaster. Induced vertigo, however, is probably what's causing the most difficulties on a roller coaster.
Fear of roller coasters, also known as veloxrotaphobia, is the extreme fear of roller coasters. It can also be informally referred to as coasterphobia. Such a fear is thought to originate from one or more of three factors: childhood trauma, fear of heights, and parental fears that “rub off” on their children.
A roller coaster ride comes to an end. Magnets on the train induce eddy currents in the braking fins, giving a smooth rise in braking force as the remaining kinetic energy is absorbed by the brakes and converted to thermal energy.
How safe are rides? According to IAAPA, there are 0.9 injuries per million rides and that in a typical year, more than 385 million guests take more than 1.7 billion rides at about 400 North American fixed-site facilities.

Air time has a strange effect on your body because your body is not completely solid — it is composed of many parts. When your body is accelerated, each part of your body accelerates individually. The seat pushes on your back, the muscles in your back push on some of your organs and those organs push on other organs.
It's important to keep your head, hands, arms, and legs inside the roller coaster whenever it's moving. You can put your hands in the air initially, but you should safely return them inside of your car for the remainder of the ride.
According to clinical psychologist Judy Kurianski, high tempo rides expose us to “good fear.” Our brains perceive the drops and heart-stopping twists to be “safe” and “predictable,” so riding these thrill rides becomes therapeutic, especially as we scream out our anxieties.
After analyzing acceleration data, it was determined that the front row had the greatest negative acceleration in the z direction and was therefore the “best place” to sit. Most people who enjoy roller coasters have a favorite place to sit when riding, but no quantitative reasons for sitting there.
However, people are actually more likely to be killed on the car ride to amusement parks than on the rides in amusement parks. As we talked about in class, car crashes kill 40,000 each year, which means around 100 everyday.
