Letter: Letters : Selective sickness

From Anne Gray

York

On a two-hour train journey the other day, your article on sickness,
“Feeling a little strange?” (14 June, p 25) came to mind.

I have always suffered from motion sickness in cars, coaches and planes. Why
have I never had it on a train, and rarely on a ship or boat?

If, as suggested, the nausea is triggered by a discrepancy between the
signals coming from the eyes and from the balance mechanism, then wouldn’t a
sure-fire method of curing it be to shut the eyes? I’ve tried this and it
doesn’t work—if anything it makes matters worse.
