Overall the brain responds to an exhilarating ride by triggering the release of a potent cocktail of biochemicals to deal with the body’s stress, including more adrenaline (epinephrine) and norepinephrine which can suppress pain and the glow of euphoria that follows. The result can be but can also be nausea. Military and Nasa researchers have studied the problem for half a century, calling it ‘simulator sickness’. But engineers and scientists have not out how to fool the senses at the same rate at the same time. They still don’t know for sure who might get sick. Meanwhile, the latest rides are the boundaries of endurance. The human body cannot take much more of a G-force than the latest rollercoasters, so we need to understand more about what distinguishes a spine-tingling thrill from a gut emptying fright to the experience is memorable for the right reasons.
