In one of the stranger research projects I’ve encountered in awhile, French scientists reported on why in the sport of discus throwing, athletes tend to feel more dizzy than those who hammer throw.
Whether discus or hammer throwing, both require spinning on part of the athlete before letting the discus/hammer go for long distances.
59% report dizziness with discus throwing, but none with hammer throwing. Why?
This occurred even among athletes who did both sports eliminating individual susceptibilities to dizziness.
Based on slow-motion video analysis, it was conjectured that Read more »

So how would one go about figuring out the best medication for dizziness due to motion-sickness leading to nausea and even vomiting?
Well, step 1… Put a bunch of people in a machine and figure out the necessary motions that will cause dizziness.
Step 2… Do the same thing, but this time, put people on different medications and figure out what works the best.
Sound crazy?
Well it has been done by the friendly folks at NASA. Read more »

I can’t read for any length of time in a moving vehicle — it makes me nauseous. This is because in order for the body to determine where it is at all times, the brain combines visual information, touch information, inner ear information, and internal expectations to judge its position in space.
Under most circumstances, the senses and expectations agree. When they disagree, there is conflict, and motion sickness can occur. In my case with reading in a car, my eyes that are fixed on the written page tell my brain that I am still. However, as the car goes over bumps and accelerates or decelerates, my inner ear disagrees resulting in my brain activating the nausea center and causing motion sickness.
Well, the same thing might happen with 3D TV. Read more »
