Jetlag 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 {{U}}(51) {{/U}} making mistakes. It is actually caused by {{U}}(52) {{/U}} of your "body clock" -a small cluster of brain cells that controls the timing of biological {{U}}(53) {{/U}}. The body clock is designed for a regular rhythm of daylight and darkness-ness, so that it is thrown out of balance when it {{U}}(54) {{/U}} daylight and darkness at the "wrong" times in a new time zone. The symptoms of jetlag often persist for days {{U}}(55) {{/U}} the internal body clock slowly adjusts to the new time zone. Now a new anti-jetlag system is {{U}}(56) {{/U}} that is based on proven tentative pioneering scientific research. Dr. Martin Moore Ede has {{U}}(57) {{/U}} a practical strategy to adjust the body clock much sooner to the new time zone {{U}}(58) {{/U}} controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates most of the discomfort of jetlag. A successful time zone shift depends on knowing the exact times to either {{U}}(59) {{/U}} or avoid bright light. Exposure sure to light at the wrong time can actually make jetlag worse. The proper schedule {{U}}(60) {{/U}} light exposure depends a great deal on {{U}}(61) {{/U}} travel plans. Data on a specific flight itinerary (旅行路线) and the individual's sleep {{U}}(62) {{/U}} are used to produce a Trip Guide with instructions on exactly when to be exposed to bright light. When the Trip Guide calls {{U}}(63) {{/U}} bright light you should spend time outdoors if possible. If it is dark outside, or the weather is bad, {{U}}(64) {{/U}} you are on an aero plane, you can use a special light device to provide the necessary light {{U}}(65) {{/U}} for a range of activities such as reading, watching TV or working. |
