For most people, taking a tropical vacation in another hemisphere or jetting off on a business trip on the other side of the world results in a case of jet lag. The most common symptom of jet lag is feeling sluggish when you arrive at your destination. Depending on the direction of your journey, on the other hand, you may feel overly alert and restless because your internal sleeping and waking clock is out of synch with the local time zone. Jet lag can also affect your digestion, your mood, and your ability to concentrate.
Fortunately, there are some simple steps you can take before, during, and after your flight to reduce the effects of traveling across several times zones.
