　　How to avoid the dreaded feelings of jet lag? Some of frequent fliers often have to adjust a sleep schedule days before a trip, seeking out bright light at certain times, or forcing the body to eat and sleep on local time immediately upon arrival.

　　The news from most researchers appears to be that the best formula is a combination of all of these tactics.

　　As a general rule, crossing more time zones makes it more difficult to avoid symptoms, which include sleepiness and confusion. Most people have body clocks that run longer than 24 hours, which generally makes it easier to fly west than east, researchers say.

　　“jet lag”解释为飞行时差反应，简称为“时差”，也可以表达为“time lag”。人在一天内跨越不同时区，由于时差的变化，使人感到眩晕(dizziness)、疲劳(weariness)、情绪失控(emotional wreck)等问题。相关的短语有：body clock(生物钟)，time zone(时区)等。
