Well, this one definitely took us by surprise when we found out about it, but it's true nonetheless, even if it does kind of go against common-sense intuition. Next time you find yourself traveling between time zones and having a hard time fighting off that pesky jet lag, try going for a run. Yeah, we know; who wants to go on a run while they have jet lag? But seriously, it does help!
Strictly speaking, you can do other things, too. It isn't just running that helps with jet lag; it's all kinds of intense physical activity that allows the body to get used to its new environment.
