Jet lag is also known as time zone change syndrome or desynchronosis. Jet lag can occur when people travel rapidly from east to west, or west to east on a jet plane.
People with jet lag have their sleep-wake patterns disturbed. They may feel drowsy, tired, irritable, lethargic and slightly disoriented. The more time zones that are crossed rapidly, the more severe jet lag symptoms are likely to be.

To avoid or minimize the effects of jet-lag, endeavour to book an overnight flight or you can book a flight that arrives in the evening when you are coming from the east so that you can catch some sleep. .
