Minimising jet lag

The symptoms of jet lag are differentiated from those of travel fatigue in that jet lag symptoms occur with rapid travel across multiple time zones, rather than with flights of the same length but along the same meridian. Typically, but not always, the symptoms are worse when travelling east and increase with the number of time zones travelled. As many as 94% of travellers suffer from jet lag, and 45% describe the symptoms as severely bothersome.
