Just a minute-full of "sound spice" may keep the motion sickness away
Nobody likes being carsick, seasick or airsick, but what can you do to keep from getting that way? Well, according to a new study, simply listening to an audio tone for one minute might be all it takes to stop you from losing your lunch.
Takumi Kagawa, Masashi Kato and colleagues at Japan's Nagoya University set about exploring that theory further, by observing how tones of different frequencies and loudnesses activated the vestibular (balance-maintaining) function of extracted mouse utricles. Live mice subsequently listened to it for five minutes, after which they were subjected to motion-sickness-inducing movement, then made to walk across a tiny balance beam. "Our study demonstrated that short-term stimulation using a unique sound called 'sound spice' alleviates symptoms of motion sickness, such as nausea and dizziness," says Kagawa.
