JET LAG & MOTION SICKNESS

Most travelers have experienced jet lag. The common symptoms - insomnia, fatigue, change in appetite, irritability - are due in part to your body's cyclical hormone production being temporarily out of synch with your activities.

In general, it takes the body one day to adjust for each time zone crossed.
