Most people who travel long distances complain of jetlag (喷气飞行时差反应). Jetlag makes business travelers less productive and more prone 61 making mistakes. It is actually caused by 62 of your "body clock" - a small cluster of brain cells that controls the timing of biological 63 . The body clock is designed for a 64 rhythm of daylight and darkness, so that it is thrown out of balance when it 65 daylight and darkness at the "wrong" times in a new time zone. The 66 of jetlag often persist for days 67 the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is 68 that is based on proven 69 pioneering scientific research.
