飞行时差

• Not everyone experiences jet lag to the same degree . some people suffer from jet lag when travelling east to west - westwards into a time zone five or more hours ahead . although there is some debate about it , most people agree that jet lag is worse when travelling west to east
  调查还发现，乘客受时差影响程度不同，有些人由东面飞向西面进入另一个时区，会感到飞行时差的徵状，但一般认为，由西面飞向东面时，受时差影响会较大。
