One of the worst parts of traveling regularly for business is the jet lag. It isn't quite so bad within the U.S, but it's still there. And if you're traveling to the longitudes of Europe, Asia or Oceania, it can throw you for a serious loop.
When you need your mind sharp to give presentations or make important business decisions, jet lag isn't a good thing. And by the time you finally adjust, you have to fly back and it starts over again, affecting your work life and home life for days or weeks.
Even worse, according to the National Institute of health, regular jet lag can increase your risk for cancer and digestive diseases. The good news is that there's plenty of research showing what jet lag is and how to combat it.
Basically, jet lag is when your body's internal clock, or circadian rhythm, doesn't match up with what's going on outside. So, for example, your body thinks it's 5 a.m. when the light outside says it's 5 p.m.
