Traveling and Jet Lag

With thousands of people traveling every day as a part of their obs, there is great concern about the effect of jet lag on business travelers. In the world of international business, many men and women have trouble performing their jobs because they feel tired and sick from all their travelling. Businesspeople are not the only professionals who suffer from jet lag. Professional sports players also find that jet lag affects their performance. I have recently read a health report and it looks at the problem of jet lag in professional baseball.

This report may be of interest to all of us, not just baseball fans. You see, researchers have wondered about how jet lag affects the job performance of people who travel for a living. The problem is that it is very difficult to measure exactly how jet lag affects most travelers, how can we measure the performance of say, an executive who travels to another country to make a business deal? This is where the idea of looking at baseball comes in. We can measure the performance of baseball players, so by looking at whether baseball teams win or lose games, researchers believe that we can see how yet lag affects performance in sports, business, and other jobs.

The study, released today, focuses on the performance of professional baseball teams. It looks at the number of games won or lost by teams after they travel to another city to play a baseball game. In the study, doctors from the University of Massachusetts Medical School and Brigham and Women's Hospital in Boston looked at baseball records from 2001 to 2004. They studied the performance of 19 teams from the Eastern and Pacific time zones, looking at the results of the two games immediately after a team traveled from one coast to the other. The study shows that changing time zones may hurt the performance of West Coast baseball teams travelling east for a game, but not East Coast teams traveling west. The reason, the researchers think, is that people traveling east suffer more form the symptom of jet lag.
