http://news.bbc.co.uk/2/hi/health/6676585.stmViagra could be used to help people flying eastwards recover from jetlag, animal research suggests.
A team of Argentine scientists found the drug helped hamsters recover up to 50% faster from forward shifts in their daily time cycles.
However, the drug only worked in conjunction with light therapy, and only in one time direction - the equivalent to flying eastbound.
The study features in Proceedings of the National Academy of Sciences.
In mammals, the light-dark cycle regulates the body's biological clock, which promotes activity during the daytime, when it is light, and sleep at night.What other uses will they find for Viagra in the future? Sounds like aspirin of the 21st century, albeit with some modifications for different uses. IIRC Viagra was first designed to be medication for high or low blood pressure. Although it didn't seem to quite work out in the original purposes which it was designed for. Quite a surprising finding.
So, don't be surprised if you see the captain of your flight walk in the plane with a woody (though, aren't they already, with all the stuertess around?). Unfortunately only applies to eastbound flights, for now.
