Flying increases your chance of a cold

I just got back from from Australia, and spent around 30 hours travelling, both on planes and through busy airports. I've also just developed a nasty cold. Coincidence? Maybe not, according to this. With all that recycled air, I'm not surprised that your risk of developing a cold onboard a plane is higher, but apparently it has more to do with what you touch than what you breath. Other causes of the flying cold? Pressure changes and a dry climate don't help, and I imagine the jet lag that comes from crossing multiple time zones doesn't help either.

So if you're flying soon, be sure to wash your hands, drink some water, eat healthfully and get some sleep!
