sama... dari kecil gue begitu mbak :D dan gua merasa puas sama jawaban hasil gugling, sbb:
Did you mean why do people get nauseated? I think that's much more common than headaches. The human body has 3 main systems that govern balance: the optical (what you see), the kinesthetic (feedback from your muscles and nerves) and the vestibular (based on fluid flow in a small organ in the inner ear.) When these 3 systems receive different signals, it causes nausea. For example, when you're looking down and reading in a car (especially if it's turning corners,) your optical system doesn't see anything moving. Your vestibular system, on the other hand, feels the motion of the car and sends signals to the brain that you are moving. The discrepancy between these signals causes the brain (for whatever reason) to give you a sense of nausea. This is why stationary amusement park rides (like Star Tours, in which the car moves somewhat while the screen gives a different picture and really confuses your brain) cause nausea more than just about any other type of ride. Movies on a curved panoramic screen (like certain IMAX theatres) can cause you very similar nausea because your vestibular system knows you're not moving, while the action on the screen tells your optical system that it's moving. In all of these cases, it's because your brain is getting mixed signals. Neither stimulus would cause you nausea normally. Closing your eyes helps. Reading in a car that's on a straight, open highway doesn't usually make you sick. -b- On Fri, May 21, 2010 at 1:42 PM, Mira Chairyah < mira.chairyahhadiy...@cimbniaga.co.id> wrote: > Teman2... > > knapa yah, sy suka pusing kl sedang di dalam mobil membaca buku/sms/bbm... > pusing dan parahnya suka mau muntah gitu.... > > Privileged/confidential information may be contained in this message.
