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. Dr. Martin Moore-Ede has

The proper schedule 74 light exposure depends a great deal on 75 travel plans.Data on a specific flight itinerary(旅行路线)and the individual's sleep 76 are used to produce a Trip Guide with 77 on exactly when to be exposed to bright light.When the Trip Guide calls 78 bright light you should spend time outdoors if possible. If it is dark outside, or the weather is bad, 79 you are on an aeroplane, you can use a special light device to provide the necessary light 80 for a range of activities such as reading, watching TV or working.
